Objective To evaluate the effect of percutaneous mechanical thrombectomy (PMT) with AngioJet mechanical thrombus aspiration system for the acute deep venous thrombosis (DVT) of lower extremities. Methods The clinical data of 72 patients (72 limbs) with acute DVT who underwent PMT with AngioJet system from December 2015 to June 2018 in our hospital were analyzed retrospectively. Results Of the 72 cases, 30 cases underwent PMT alone, while 42 cases underwent PMT combined with catheter directed thrombolysis (CDT). Thrombus clearance rate of grade Ⅲ was obtained in 49 cases (68.05%), grade Ⅱ in 20 cases (27.78%), and grade Ⅰ in 3 cases (4.17%). Thirty-five cases were found with May-Thurner syndrome, and 34 cases were treated with stenting while 1 case complicated with iliac bleeding. The rates of PTS were 1.41% (1/71), 3.57% (2/56), 4.55% (2/44), and 20.00% (3/15) at 3-month, 6-month, 1-year, and 2-year after intervention, respectively. The deep vein patency rates were 86.36% (38/44) and 80.00% (12/15) at 1-year and 2-year after intervention, respectively. The iliac stent patency rates were 100% (23/23) and 87.50% (7/8) at 1-year and 2-year after intervention, respectively. Conclusion The effect of PMT assisted with CDT for the acute DVT of lower extremities is satisfactory, but its long-term efficacy needs to be further observed.
