ObjectiveTo compare the efficiency of preventing PE, retrieval and complications between OptEase filter and Tulip filter By case-control studying in DVT patients.Method123 cases of DVT patients in February 2006~December 2008, are divided into Tulip filter group and OptEase filters group according to the type of filters, and follow up from 13 to 46 months. The follow-up methods include radiography,ultrasound and angiography to examine the shape,location of filters and thrombosis in inferior vena cava or lower extremity vein after surgery. If chest pain, shortness of breath, Dyspnea and other symptoms of PE appear in follow-up period, diagnose by 3DCT immediately Use X2 test to compare the data collected (P>0.05)ResultsTechnical success rate was 100% in the filter placement in two groups, no intraoperative complications and near term complications. None occurred PE during hospitalization and follow-up periods.No filter fracture, penetrate the vessel wall. The success rate of retrieval is 90%in OptEase filter group,and the rate in Tulip filter group is 100%.Among the unretrieved patients, deep vein thrombosis occurred in 3 patients (7.3%), inferior vena cava thrombosis occurred in 1 patient (2.4%) in OptEase filter group, tilt occurred in 2 patients(4.7%). Deep vein thrombosis occurred in 3 patients (7%), and inferior vena cava thrombosis occurred in 1 patient(2.3%) in Tulip filter group.ConclusionsResults by X 2 test found to be no statistically difference. |
