Interventional treatment for acute iliofemoral venous thrombosis: a comparison between angioJet rheolytic thrombectomy and manual aspiration thrombectomy

Objective To compare the clinical efficacy of angioJet rheolytic thrombectomy (ART) and manual aspiration thrombectomy (MAT) combined with catheter-directed thrombolysis (CDT) in the treatment of acute iliofemoral venous thrombosis (IFVT). Methods 62 acute IFVT patients undergoing interventional treatment with either ART (group A, 30 cases) or MAT (group B, 32 cases) from 2014 to 2016, were enrolled in this study.Clinical efficacy and postthrombotic syndrome (PTS) rate were compared between the two groups. Results The instant thrombolysis rate in group A was 83.3% (25/30), that was 59.4% (19/32) in group B(P 0.05). No severe complications occurred during the treatment of ART and MAT procedure.Fifty seven cases (91.9%) were followed-up, the valvular regurgitation rate in group A and group B were 14.3% (4/28) and 37.9% (11/29), respectively (P 0.05). Conclusions Interventional treatment for acute IFVT with ART and MAT can both achieve high clinical efficacy.ART are with higher instant thrombolysis rate and less valvular regurgitation compared with MAT.
