Endovascular treatment for ruptured femoral artery pseudoaneurysm associated with bleeding caused by injection of addictive drug / 介入放射学杂志

ABSTRACT

Objective To investigate the feasibility,safety and effectiveness of endovascular angioplasty with covered stent and embolization with spring coil in treating ruptured femoral artery pseudoaneurysm (FAP) associated with bleeding caused by injection of addictive drug.Methods The clinical data of 32 patients with ruptured FAP complicated by bleeding caused by injection of addictive drug,who were admitted to authors' hospital during the period from July 2012 to December 2015,were retrospectively analyzed.The average age of the patients was 36.5 years old,among them 25 patients were male (78.1％).Results Successful hemostasis was achieved in all 32 patients.The technical success rate of endovascular therapy was 100％,and no death occurred during perioperative period.Endovascular repair with covered stent was carried out in 25 patients (78.1％),embolization of femoral profound artery with spring coil in 9 patients (9.4％),and covered stent implantation together with embolization of femoral profound artery in 4 patients (12.5％).The patients were followed up for a mean of (17.5±11.6) months,with a follow-up rate being 93.8％ (30/32).The 3-year cumulative stent patency rate was 90.9％,and the 3-year overall survival rate was 91.3％.Conclusion For the treatment of ruptured FAP complicated by bleeding caused by injection of addictive drug,endovascular treatment is safe and effective with satisfactory mid-term clinical effect.This technique helps win the valuable time for critically ill patients to receive two-stage surgical debridement and vascular repair,as two-stage thorough debridement is an important means to control infection.
