A 21-year-old Indonesian woman came to hospital with severe headache and vomiting. Brain MRI showed multiple subcortical lesions. High-intensity transient signals (HITS) was detected in the carotid artery and transesophageal echocardiography (TEE) was performed to search for embolic sources. Mobile string-like structures were found in the aortic arch. We started anticoagulation therapy. One month later, TEE reexamination revealed that the aortic arch cord had shrunk, but numerous cords were found in the pulmonary artery. She was suspected with Angiostrongylus cantonensis infection and treated with antiparasitic agent and steroids. One month later, the TEE was performed again, and the cord-like structure in the aortic arch almost disappeared, and the abnormal structure in the pulmonary artery also disappeared. It is known that A. cantonensis can cause eosinophilic meningoencephalitis, but its prognosis is good, and it is thought that it may be mild. In this case, although the definitive diagnosis has not been made, the possibility was considered to be high because antiparasitic agent was effective. HITS detection for investigating the cause of multiple subcortical lesions was considered to be useful in determining the embolic mechanism.

Purpose: We attempted to detect high intensity transient signals (HITS) at common carotid artery (carotid HITS) by paste type Doppler probe in residents at Kashiwazaki City where big earthquake occurred in 2008. Calf deep venous thrombosis (DVT) has been detected frequently in the residents due to earthquake. It was examined whether it relates to DVT, cerebro-cardiovascular diseases (CCVDs), etc. Subjects and Methods: We conducted screening for 522 residents in Kashiwazaki City in 2016–2017. HITS were detected by using 2.0MHz paste type probe at carotid artery for 5min. Results: Carotid HITS was detected in 39 (7.5%). Statistically significant risk factors in the carotid HITS positive group were arterial velocity pulse index (AVI), CCVDs and atrial fibrillation. Univariate analysis of cerebro-cardiovascular disease indicated an odds ratio of 3.8 (95% CI: 1.8–7.9, p = 0.001) in the carotid HITS positive, and furthermore odds ratio 3.6 (95% CI: 1.6–7.9, p = 0.001) was found in the same group in multivariate analysis. Conclusion: Carotid HITS was a significant risk factor for CCVDs and atrial fibrillation in the general population. Therefore, it was suggested that detection of HITS at carotid artery by paste type probe may be useful for prevention of embolic disease.

For a period of 4 years, we conducted deep vein thrombosis (DVT) examinations among people living in temporary homes and those living in their own homes in areas affected by the Great East Japan Earthquake. We divided those with positive results for DVT after receiving numerous examinations into a DVT disappeared group and a DVT remained group. The thrombus formation sites were the soleus muscle veins for both groups. In terms of characteristics, multiple organized thrombi were recognized, and there was no spread to the central side. In addition, the DVT remained group exhibited an increased maximum diameter of the soleal vein. We believe that stasis of blood flow due to the extension of the soleal veins contributed to the continued formation of thrombi.

Language：Japanese Publisher：Japanese Society of Phlebology

The emergency shelters for Joso flood disaster in 2015 and the 2016 Kumamoto earthquake were set up immediately after both disasters occurred. After Niigata Chuetsu earthquake in 2004, significant rates of the evacuees with deep vein thrombosis (DVT) were reported. Since then, many vascular ultrasound examinations for DVT have been performed in the shelters for each disaster and therefore, the examinations for evacuees of both disasters were also performed. After medical interviews, blood pressure and oxygen saturation measurements, vascular ultrasound examinations for calf were conducted in a sitting position. Elastic compression stockings were handed out to the evacuees at the end of examination. To reduce disaster related death, it is important to prevent the occurrence of critical pulmonary thromboembolism and so, examinations for early detection of DVT in the shelters are quite meaningful.

Introduction: The aim of this study is to clarify the important role of deep venous thrombosis (DVT) in disaster refugees. Methods: We visited the Minami-sanriku Tome shelter in Miyagi Prefecture, one of the areas affected by the Great East Japan Earthquake, to examine the incidence of DVT by using an ultrasound device from March 14 to May 4, 2011. One hundred eighty-seven people, who were aged over 60 years and had lower limb trauma, lower limb symptoms, a history of lengthy periods of resting inside a car, and/or a motionless lifestyle in the shelter, participated in the examination. The ultrasound examination was mainly intended to check for DVT findings below the knee. Results: The incidence of DVT in the participants was 5.3% (10/187). When comparing those with DVT with those without, age, percentage of women, and percentage with lower limb trauma were significantly higher in DVT patients than in non-DVT people. After logistic regression analysis, lower limb trauma was an independent strong risk factor for DVT (p < 0.0001, odds ratio=26.5). Conclusion: In conclusion, lower limb trauma is the most important cause of DVT formation in disaster refugees.

Open Surgery for Giant Bilateral Internal Iliac Artery Aneurysms with Compression of Neighboring Abdominal Structures: A Case Report.

Atsushi Morishita, Hideyuki Tomioka, Seiichiro Katahira, Takeshi Hoshino, Kazuhiko Hanzawa

Annals of vascular diseases 8 ( 3 ) 265 - 7 2015

Language：English

We describe a patient with successfully treated giant bilateral internal iliac artery aneurysms that were associated with acute renal failure secondary to bilateral hydronephrosis, lumbosacral plexopathy, and ileus. After hemodialysis for 1 month, the patient underwent graft replacement of the abdominal aorta and iliac arteries, including complete obliteration of the internal iliac artery branches, reconstruction of the inferior mesenteric artery, and ureterolysis. Weaning from hemodialysis was achieved and postoperative renal function improved. Although the patient had serious preoperative co-morbidities, emergency traditional open surgery should be the gold standard for securely releasing compression of the neighboring organs instead of endovascular treatment.

OBJECTIVE: To estimate the frequency of deep vein thrombosis (DVT) among non-surgical inpatients, and to evaluate the D-dimer assay as a screening tool for DVT. METHODS: Subjects were non-surgical inpatients aged 20 years or older who had been bedridden for at least 24 hours and had moderate-to-high risk factors for DVT. We assessed the presence of DVT by venous ultrasonography. Patients who received a diagnosis of venous thromboembolism (VTE) before admission, who had symptoms or findings of VTE at admission, or who had surgery or trauma within the past 3 months before admission were excluded. RESULTS: DVT was confirmed in 96 of 525 patients (18.3%). In a logistic regression analysis, longer duration of hospitalization, higher D-dimer value, and history of cancer surgery were significantly associated with the occurrence of DVT. The D-dimer assay showed high sensitivity (96.1%) and high negative predictive value (97.6%). CONCLUSION: Non-surgical inpatients with a long-term hospitalization or history of cancer surgery have a risk for DVT, and need to be considered for added DVT preventive measures as recommended in the prevention guidelines. In addition, the D-dimer assay is beneficial for the screening of DVT in medical practice.

A case of reversible cerebral vasoconstriction syndrome with multiple high-intensity transient signals on transcranial Doppler

Neurosonology 27 ( 2 ) 76 - 79 2014

Language：Japanese Publisher：The Japan Academy of Neurosonology

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by acute thunderclap headaches with or without other neurological symptoms, and reversible multi-segmental vasoconstriction of the cerebral arteries. We describe the case of a 49-year-old woman presenting with severe, sudden-onset headaches and multi-segmental vasoconstriction of the cerebral arteries demonstrated on magnetic resonance angiography (MRA). Headaches disappeared within several days, and vasoconstriction of cerebral arteries was markedly improved 6 weeks after the onset. We therefore diagnosed RCVS. In addition to MRA, we repeatedly performed transcranial-color flow imaging (TC-CFI) and transcranial Doppler ultrasonography (TCD) to evaluate cerebral arterial blood flow and risk of cerebral infarction. The first TCD study was performed 6 weeks after the onset; 11 high-intensity transient signals (HITS) were detected in 30 min at the region of vasoconstriction in the right MCA. To the best of our knowledge, this is the first report of HITS-positive RCVS. Ten weeks after the onset, MRA demonstrated disappearance of cerebral arterial vasoconstriction, and TCD detected only 1 HITS in 30 min. Interestingly, TC-CFI still indicated elevated flow velocity in the bilateral MCAs. These findings suggest that TC-CFI may be more sensitive and useful than MRA for diagnosis of RCVS.

Language：Japanese Publisher：The Japan Academy of Neurosonology

Background and Purpose: Deep venous thrombosis (DVT) in the upper part of the body is rare, accounting for approximately 1 – 4% of all DVTs. The incidence and clinical significance of jugular vein thrombosis (JVT) were investigated in consecutive patients with acute ischemic stroke. Subjects and Methods: From December 2006 to March 2007, 71 patients (46 men, aged 70.8 ± 13.2 years) hospitalized within 48 hours after ischemic stroke or TIA onset were retrospectively examined. The presence of JVT was evaluated by ultrasonography. Patients with jugular vein catheterization were not included. Age, sex, hypertension, diabetes mellitus, hyperlipidemia, smoking status, presence of a malignant tumor, and D-dimer were assessed. Results: JVT was demonstrated in four patients (5.6%). The rate of a malignant tumor was significantly higher in patients with JVT than in those without (100% vs. 14.9%, p<0.001). The tumors were as follows: esophageal cancer (1); lung cancer (1); and uterine cervical cancer (2). The stroke subtype in three patients was Trousseau syndrome with a high D-dimer value, and that in the other patient was a lacunar stroke with a normal D-dimer value. Conclusions: Ultrasonographic evidence of JVT in patients with acute ischemic stroke could be a marker of a coincidental malignant tumor with or without Trousseau syndrome.

One-year overview of deep vein thrombosis prevalence in the ishinomaki area since the great East Japan earthquake.

Shinsaku Ueda, Kazuhiko Hanzawa, Muneichi Shibata

Annals of vascular diseases 7 ( 4 ) 365 - 8 2014

Language：English

After the Great East-Japan Earthquake, the prevalence of deep vein thrombosis (DVT) in disaster shelters in Ishinomaki (Pacific coast, Miyagi, Japan) was found much higher than that ever reported in Japan. In Ishinomaki, twelve patients were found to have pulmonary thromboembolism for one month since the earthquake and DVT was found in 10 of those patients. The calf DVT was examined using ultrasonography in the shelters (from March to July 2011) and in temporary emergency housings (from August to December 2011). Calf DVT was found in 190 of 701 evacuees. DVT prevalence was higher in the tsunami-flooded shelters (34.2%) than in that in the non-flooded shelters (19.1%). This indicated that deteriorated and crowded condition in the tsunami-flooded shelters might induce thrombogenesis in calf veins. Therefore, evacuees were recommended to leave tsunami-flooded areas. DVT prevalence in the shelters was gradually reduced, however, that was still higher in the temporary emergency housings (8.9%) than in the non-disaster area in Japan (2.2% in Yokohama city). The risk of calf DVT in the temporary emergency housings was increased because of reduced blood flow in the calf veins caused by immobility. The residents of the housings were required to be physically active to avoid calf DVT. (English translation of Jpn J Phlebol 2013; 24: 380-384).

Delayed visceral and spinal cord malperfusion after axillo-bifemoral bypass for complicated acute type B aortic dissection.

Atsushi Morishita, Hideyuki Tomioka, Seiichiro Katahira, Takeshi Hoshino, Kazuhiko Hanzawa

Annals of vascular diseases 7 ( 3 ) 331 - 4 2014

Language：English

We describe a successfully treated case of acute type B aortic dissection complicated with lower extremity, visceral, and spinal cord malperfusion. To restore perfusion to both lower extremities, we performed an emergency right axillo-bifemoral bypass. Furthermore, we performed total arch replacement, including primary entry closure, because of delayed visceral organ ischemia. Unexpectedly, delayed paraplegia occurred after hospital discharge; however, the patient recovered without any neurologic sequelae after early introduction of hyperbaric oxygen therapy. Because another episode of organ malperfusion in the long term cannot be anticipated, and even though the previous organ malperfusion episode was treated successfully, close observation is mandatory for detecting clinical manifestations in combination with the availability of imaging modalities.

An 86-year-old man was admitted for abdominal pain. Dissected descending thoracic aortic aneurysm and infrarenal abdominal aortic aneurysm were observed under computed tomographic (CT) scan. Hematologic studies revealed low platelet count and an increase in fibrin degradation products (FDP), and disseminated intravascular coagulation( DIC) associated with dissecting aortic aneurysm was highly suspected. Platelet transfusion was performed and gabexate mesilate was administered, however, no improvement of DIC could be obtained. An increase in aortic diameter was observed under CT scan and surgery was performed. The infrarenal aneurysm was replaced with a bifurcated prosthetic graft under open repair. Simultaneously, an endovascular stent-graft was delivered from the left limb of the abdominal graft and implanted into the descending thoracic aorta. The postoperative recovery was uneventful but platelet count did not improve in this case.

Background and Purpose: Venous thromboembolism is one of the leading causes of mortality during the acute recovery phase of cerebrovascular disease. Ultrasonographic examination is a powerful tool for detecting and predicting deep vein thrombosis (DVT). However, little is known about the clinical significance of deep vein dilatation in a recumbent position in acute cerebrovascular disease patients. We investigated the relationship between DVT and deep vein diameters in the lower limbs in acute cerebrovascular disease patients. Subjects and Methods: From January to June 2010, a total of 86 patients hospitalized within 48 hours after cerebrovascular disease onset had their lower limbs examined using duplex ultrasonography within 7 days after admission. The predictive value of deep vein diameters for the presence of DVT was examined using logistic regression analyses. Results: DVT was detected in 16 patients with acute stroke. The diameters of the popliteal veins (POVs) in the DVT group were significantly greater than those in the non-DVT group, 9.1±3.4 mm and 7.1±1.9 mm, respectively (p=0.001). However, there was no significant difference in the soleal vein diameters. Univariate logistic regression analysis showed a significantly higher odds ratio [OR] of the 4th quartile of the POV diameter (8.4–19.3 mm) compared to the 1st quartile (OR: 5.54, 95% confidence interval [CI], 1.01–30.50; p=0.049). Conclusions: POV dilatation (>8.4 mm) in a recumbent position is associated with DVT in acute cerebrovascular disease patients.

Transcranial Doppler (TCD) monitoring during cardiovascular surgery

Language：Japanese Publisher：The Japan Society of Ultrasonics in Medicine

The leading causes of cerebral injury during cardiovascular (CV) surgery are cerebral blood flow (CBF) insufficiency and embolism. TCD can detect both CBF velocity and micro-emboli in cerebral arteries. However, the middle cerebral artery (MCA) cannot always be detected by the temporal bone approach in elderly Japanese, in whom monitoring of the extra-cranial internal carotid artery (ICA) by the infra-mandible approach is recommended. CBF velocity measured by TCD is useful for cardiopulmonary bypass or selective cerebral perfusion. Most HITS/MES detected by TCD during CV surgery indicate micro-bubbles. However, many micro-bubbles cause cerebral injury. Cerebral protection therapy is needed in case numerous HITS/MES are detected during CV surgery.

By the Niigata Chuetsu earthquake generated in 2004, 10 Pulmonary embolism (PE) was reported, and 3 people of those died. In addition, Deep vein thrombosis (DVT) was accepted to 30.4% of the person of object in investigation performed within two weeks when earthquake outbreak. PE is caused primarily by DVT. Because of these factors, necessity of the early detection of the DVT rises. When DVT occurred, venous blood obstructed a flow concentrates on epibiosis vein. Therefore burdens to the vein increase, and the expansion of the blood vessel is predicted. Near-Infrared ray (wavelength: 780nm) which it is easy to penetrate skin, and absorbed by deoxyhemoglobin. Therefore We built the epibiosis vein imaging device which We used Near-Infrared ray (wavelength: 780nm) and examined the use to Deep vein thrombosis risk evaluation.

The Risk of Deep Vein Thrombosis of the Lower Extremities in Patients with Chronic Respiratory Disorders, based on the Results of Ultrasonography Screening

SOGAWA Yuichiro, YOSHIMINE Fumitoshi, HANZAWA Kazuhiko

The Japanese Journal of Rehabilitation Medicine 45 ( 1 ) 40 - 45 2008.1

Language：Japanese Publisher：The Japanese Association of Rehabilitation Medicine

We screened patients with chronic respiratory disorders for deep vein thrombosis (DVT) of the lower extremities using ultrasonography. These patients require pulmonary rehabilitation because of their physical disabilities and the reduction in their activities of daily living (ADL). The average soleus vein diameter, which is the reported source of most DVTs, was 6.1±1.5 mm in the control group, 6.8±2.1 mm in the home oxygen therapy (HOT) patients, and 7.0±1.6 mm in the non-HOT patients. The soleus vein diameters in the HOT and non-HOT patients were significantly greater than in the control group (p=0.003). The prevalence of calf DVTs in the HOT patients was significantly higher than in the non-HOT patients (14.3 % vs. 2.0 %, p=0.027). Therefore, patients with chronic respiratory disorders are at greater risks of developing DVT. Furthermore, it appears that not only the deterioration in ADL but also the presence of respiratory disorders and a hypoxic state may influence the onset of DVT in HOT patients. Chronic respiratory disorder is thought to be one of the risk factors for DVT. Therefore, preventive measures, such as ultrasonographic screening examinations, daily living guidance, and physical therapy, are important for patients with chronic respiratory disorders.

We encountered 2 cases of pulmonary thromboembolism developed during refuge for Niigata Chuetsu earthquake in 2004. Case 1 was a 76-year-old woman who moved to the back seat of a car for refuge since the earthquake struck on October 23rd, 2004. When she emerged from the car on the morning of October 25th, she felt sudden dyspnea and lost consciousness. On arrival at the hospital, she had low blood pressure and hypoxemia, hypocapnia, and metabolic acidosis. Based on her clinical history and her symptoms, pulmonary thromboembolism was suspected and heparinization was begun immediately. In our hospital, the chest CT angiography proved the diagnosis. She was transferred to a university hospital for further treatment. Case 2 was a 79-year-old woman. She spent only one night in a car. Fifteen days after the earthquake, chest tightness and dyspnea occurred. Although her symptoms were improved and disappeared, she came to our hospital. Chest CT images confirmed pulmonary thromboembolism, and treatment with heparin was begun. We think this pulmonary thromboembolism was related to the knee-bending position she had assumed in the car and decreased activity during refuge. This is a clinical condition which could happen during disasters in the future. We should recognize the likelihood of pulmonary thromboembolisms in the disasters in the future.

はじめに 平成16年10月23日午後5時56分新潟県中越地震が起こった。ライフラインが断たれ多くの方が避難所生活を余儀なくされた。一向に収まらない余震に、１万人以上といわれる車中生活者が見られたのが特徴であった。車から出た途端に血栓症で倒れて亡くなる、所謂エコノミークラス症候群の疑いの死亡者が報道されるようになった。そこで、新潟大学呼吸循環外科・榛沢医師が各避難所を回り調査した結果30％の高率で血栓が見つかった。それをふまえ定置での検査も必要と考え、被災地のほぼ中心に位置する当院でエコー検査を実施した。より多くの被災者に知ってもらうため避難所にポスターを貼り、メディアの協力を得て呼びかけを行なった。 期間 前期平成16年11月15・17・22・24・29日 12月6・13・20・27日の9日間 後期平成17年2月28日 3月4・7・14・17・22・28日の7日間 対象 １）前期：車中泊の経験者・足の痛み・腫れ・浮腫のある方 男性16名（40歳から81歳）女性67名（28歳から83歳）の計83名 平均年齢59.5歳 ２）後期：前期被検者で再検を希望した人32名 結果 前期：症状あり73名（下肢腫脹・疼痛・足がつる・熱感・違和感・関節痛）症状なし10名 慢性血栓（壁在血栓）8名充満血栓や浮遊血栓2名 12％に血栓を確認 車中泊連続20日以上8名（全員症状はあるが血栓なし）車中泊経験者は血栓が消失しても浮腫・疼痛が残る。 後期：症状あり21名（下肢腫脹・下肢疼痛など） 症状なし11名 浮遊血栓を再度確認1名新たな浮遊血栓2名壁在血栓3名静脈瘤血栓1名 21.9％に血栓を確認 考察 11月12月の検査では12％が陽性と診断された。これは、車中生活で長時間同じ姿勢の維持、トイレの回数を減らす為に水分を摂らずにいた為と考えられる。また、2月・3月のフォローアップでは、21.9％に血栓が見られた。前回異常のなかった2名に血栓が見つかり、参考に行ったＤダイマー検査でも陽性を示した。これらのことから、早期発見の重要性とフォローアップの必要性がある。死亡者を出さないためにも車中泊での問題点や注意点を啓蒙していかなければならない。今回、県内各病院の検査技師からボランティア（延べ40名）からエコー検査に協力して貰った。全国各地で地震が起こっている。今回の経験を生かし、検査技師会を通じて下肢静脈エコー検査の有用性を知って貰い、災害時に検査技師として、率先して現地に赴き、エコノミークラス症候群の早期発見に努めるよう提起していきたいと考えている。

A proposal has been made to introduce a new Japanese guideline for detection of micro-embolic signals using trans-cranial Doppler (TCD). This guideline is in accordance with the Consensus on Micro-Embolus Detection by TCD proposed by the International Consensus Group on Micro-Embolus Detection in 1998. Micro-embolic signals are called HITS or MES. HITS include artifacts in place of MES. Recommended settings are: (1) use of a 2-MHz probe; (2) sample volume within 10 mm; (3) power set as low as reasonably possible; and (4) use of a headband to affix the TCD probe. The characteristics of HITS/MES are: (5) an intensity at least 3 dB higher than the background that reflects the blood stream; (6) a recording time of more than 30 minutes but not more than one hour to maintain the normal brain temperature; and (7) signals without associated sounds or a low emboli-blood ratio (EBR) excluding HITS. Other recommendations include: (8) recording HITS as digital data, using digital audio tape or CD-R; (9) having data double-checked by an expert who is not familiar with the clinical profile of the examinee; and (10) checking all data manually. The results are better than those obtained from an automatically detected HITS/MES system that is not yet at the completion stage.

Antiphospholipid antibody syndrome (APS), which produces various clinical manifestations including arteriovenous thrombosis, recurrent spontaneous abortion, and thrombocytopenia is recognized as one of the causes of cerebral infarction in young people. It has recently been reported that microembolic signals (MES) detected by transcranial Doppler sonography might be related to cerebral ischemia in APS patients. High intensity transient signals (HITS) were studied in a 38-year-old female with APS associated with a lupus-like condition for 15 months after cerebral infarction. Interestingly, both the number of HITS and the acoustic power of HITS increased remarkably during the acute phase. This is the first prospective case report of HITS in an APS patient who developed cerebral infarction.

Transcranial Doppler ultrasound (TCD) can detect circulating microembolic signals (MES) from a variety of embolic sources. We mentioned about MES detection by TCD, MES detection in patients with ischemic stroke, and tail signs (TS) . A prevalence of MES of 5.7% was found in 151 consecutive patients with ischemic stroke. TCD was useful to confirm the stroke mechanism and to predict individual prognosis in some patients. The prevalence of MES was low and TCD did not always detect MES in patients with ischemic stroke. Our attention also focused on TS, which appeared as a small reversal signal after MES on the high time resolution spectral display. MES and artifacts were examined in experimental animals to determine whether TS were specific changes associated with MES, and TS were investigated in both animal and clinical studies. TS associated with MES were observed in both animal and clinical studies, and were never associated with artifacts. These results indicate that TS are highly specific for MES and can be used as another criterion for MES identification.

Cardiogenic embolism is one of the main causes of stroke. We analyzed the prevalence of microembolic signals (MES) in patients with recent cardiogenic embolism using a multigate technique. We examined 9 patients with cardiogenic embolism and 10 healthy controls, performing transcranial Doppler (TCD) monitoring from one middle cerebral artery using a 2-MHz probe of a multigated tanscranial pulsed Doppler system. The prevalence of MES was 22%. Most of the patients receiving antithrombotic therapy showed no MES. Two patients with acute stroke before initiation of therapy had no MES. In one of them, TCD detected no MES at 4 days after the onset of stroke, but another embolic stroke recurred only one day after TCD monitoring. All the healthy controls were free of MES. TCD was useful for confirming the stroke mechanism and for predicting individual prognosis in some patients. The prevalence of MES was not so high, and TCD did not always detect MES in patients with acute cardiogenic embolism. Recording for longer than 30 min, or on multiple occasions per patient will be necessary.

We detected HITS in patients with a risk of embolic stroke and V-A ECMO. HITS was detected by TC2020 (EME) with 2.0MHz probe at MCA artery for 15min. HITS was never detected in healthy volunteers (n=20). HITS count in patients with no cerebrovascular disease was 0.5 (n=17). The count in patients receiving open heart surgery without mechanical valve was 0.08 (n=11). In cerebral infarction, HITS was frequently detected, and the counts in patients having antiplatelets (3, n=20) was significantly lower than that in those without antiplatelets (13, n=22) (p<0.01). In mechanical valve replacement, HITS was more frequently than cerebral infarction, and the count in patients suffering from cerebral infarction (83, n=8) was significantly higher her than that in those without a history of stroke (7, n=42) (p<0.01). HITS in patients with V-A ECMO was 118 (ACT=200 sec, n=6) and the count reduced by prolonging ACT. In V-V ECMO, HITS was not detected. HITS was frequently detected in patients with a risk of cerebral infarction. Furthermore, HITS count appeared to be reduced by antiplatelet or anticoagulation therapy. HITS may indicate a risk of embolic event and useful for managing of V-A ECMD.
