Abstract

After previous earthquakes, high prevalence of cardiovascular diseases including venous thromboembolism (VTE) has been reported. We performed venous screening at the site of Hokkaido East Iburi Earthquake which happened at 6th September 2018. VTE screening using ultrasound sonography was performed for total 7 days at Atsuma town, Mukawa town and Abira town (total 9 shelters). Deep vein thrombosis (DVT) was found in 19 of 195 evacuees (9.7%), including 8 fresh thrombus cases (4.1%). On multivariable analysis of evacuees and shelter environment factors, systolic blood pressure, use of cardboard bed and toilet environment were significant predictor of DVT. Introduction and setting-up of cardboard beds were found as an important shelter environment factor. (This is secondary publication from Jpn J Phlebol 2021; 32(1): 5–10.)
