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.

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.
