AngioJet rheolytic thrombectomy for the treatment of acute deep venous thrombosis of lower extremity / 介入放射学杂志

ABSTRACT

Objective To discuss the efficacy and complications of using AngioJet rheolytic thrombectomy in treating acute lower extremity deep vein thrombosis (DVT).Methods The clinical data of 22 patients with acute lower extremity DVT,who were treated with AngioJet rheolytic thrombectomy during the period from February 2015 to August 2016,were retrospectively analyzed.The improvement of clinical symptoms and the thrombus clearance rate were calculated to evaluate the curative effect.The procedure-related complications were documented.Results The clinical symptoms were relieved immediately after operation in all 22 patients.The thigh circumference difference between the affected side and the healthy side decreased from preoperative (4.5±0.6) cm to postoperative (1.0±0.4) cm,the difference in change was statistically significant (P＜0.05).The mean used dose of urokinase was (0.18±0.03) million unit and the average duration of thrombolysis was (4.2±0.7) hours.Complete removal of DVT (＞90％) was achieved in 19 patients,most removal of DVT (50％-90％) in 2 patients,and partial removal of DVT (＜50％) in one patient.After treatment,6 patients developed transient hemoglobinuria,which was relieved after hydration with fluid infusion on the same day.No serious complications such as pulmonary embolism or hemorrhage occurred.Conclusion For the treatment of acute lower extremity DVT,AngioJet rheolytic thrombectomy is safe and effective with less complications.
