AngioJet mechanical thrombectomy for lower deep venous thrombosis / 中华普通外科杂志

ABSTRACT

Objective To evaluate percutaneous AngioJet thrombectomy in the treatment of iliofemoral deep venous thrombosis (DVT).Methods A total of 36 patients with 38 legs of lower extremity DVT treated by AngioJet mechanical thrombectomy from Feb 2016 to Dec 2016 were analyzed retrospectively.The effect of lower limb venous recanalization was evaluated by observing the intraoperativeangiography and the results of postoperative follow-up including complaints,signs,and lower extremity venous ultrasound or CT and Villalta scores.Results Thrombosis was completely dissolved by AngioJet thrombectomy device in 32 out of 38 legs (84.2％) at first stage.Slight bleeding occurred in 4 cases,1 patient could not tolerate the operation.23 patients were followed-up for 6 months,venous patency was present in 21 of 23 patients (91.3％).11 patients complete the one-year follow-up,9 patients (81.8％) were in the 0-4 Villalta group.Conclusions AngioJet can effectively and safely remove thrombus in the lower extremity deep venous system.It is especially advantageous for patients who have contraindications for thrombolysis with a satisfactory short term venous patency.
