BackgroundThe aim of this study is to examine the efficacy and safety of AngioJet rheolytic thrombectomy for the treatment of subacute deep venous thrombosis (DVT) in lower limbs.MethodsA retrospective study was performed on 90 patients with subacute DVT (15-90 days) in lower limbs in our center from November 2015 to December 2016. In total, 27 patients with subacute DVT in lower limbs treated with AngioJet rheolytic thrombectomy were included in the study, including 17 men and 10 women. The onset time of thrombosis was between 15 and 75 days. Five patients were diagnosed bilaterally; 5 patients were diagnosed in the right lower limb; and 17 patients were affected by thrombosis in left lower limb. All the 27 cases received AngioJet rheolytic thrombectomy.ResultsAfter AngioJet thrombectomy, 17 cases were improved to grade II (50-99%), and 10 cases were grade I (<50%). Nineteen cases were treated with subsequent catheter-directed thrombolysis (CDT), and the average time of thrombolysis was 3.2 days, with an average urokinase administration dose of 7.32 million units. Among the 27 cases, 21 of them received iliac venous balloon dilation, with 10 of them being implanted with the iliac vein stent; 12 stents were implanted in total. Finally, the angiography suggested that 25 cases (92.6%) obtained a recanalization rate higher than grade II, and no serious complications occurred during the perioperative period. All patients were followed up regularly for 3 to 15 months, and 2 patients died from malignant tumor during the follow-up period. Twenty-three cases were followed up for more than 6 months; 17 cases finished 12-month follow-up. The primary patency rate at 6 and 12 months was 96.3% and 88.9%, respectively. The Villalta score of postoperative postthrombosis syndrome symptom at 6 and 12 months was 3.3 ± 2.8 and 3.5 ± 2.8, respectively.ConclusionsIt is safe and feasible to use the AngioJet rheolytic thrombectomy in the treatment of subacute DVT in lower limbs. In patients without high risk of bleeding, combination of AngioJet thrombectomy and CDT is an effective treatment to reduce the thrombus volume.Copyright © 2019 Elsevier Inc. All rights reserved.
