Percutaneous mechanical thrombectomy combined with catheter-directed thrombolysis in the treatment of deep venous thrombosis of lower extremity via contralateral femoral vein approach / 上海交通大学学报（医学版）

ABSTRACT

Objective: To analyze the early clinical effects of acute deep venous thrombosis (DVT) of the lower extremities through a contralateral femoral vein approach by percutaneous mechanical thrombectomy (PMT) combined with catheter-directed thrombolysis (CDT) therapy. Methods: A retrospective analysis about 45 patients (from September 2016 to August 2017) was conducted to analyze the success rate of the technique, the degree of thrombolysis in different venous segments, and the incidence of complications during the treatment of PMT+CDT. Results: Technique successful rate was 100%. 86.7% of lower extremity thrombosis (LET) segments (calf veins), 82.2% of LET Ⅱ segments (femoral and popliteal veins) and 71.1% of LET III segments (common iliac and femoral veins) were completely dissolved. No serious complications occurred. Conclusion: It is feasible, safe and effective to use PMT+CDT in acute DVT.
