Treatment of type 2 endoleaks after endovascular repair of abdominal aortic aneurysms: Comparison of transarterial and translumbar techniques

摘要: Abstract Objective: The exact significance of collateral endoleaks is unknown and a topic great debate. Because this uncertainty, some physicians choose to watch wait while others aggressively treat these leaks. purpose investigation was the evaluation efficacy two techniques used in treatment that occur after endovascular aneurysm repair. Methods: Patients with 33 angiographically proven type 2 underwent either transarterial inferior mesenteric artery embolization (n = 20) or direct translumbar 13) during an 18-month period. Embolization success defined as resolution endoleak on all subsequent computed tomography angiogram results. likelihood failure between treatments expressed risk ratio compared Fisher test. Results: Sixteen 20 embolizations (80%) failed recanalization original cavity over time. A single (8%) group occurred patient whom new attachment site leak developed. remaining 12 (92%) were successful durable, median follow-up period 254 days. patients who significantly more likely have persistent than (risk ratio, 4.6; 95% confidence interval, 1.9 11.2; P=.0001). Conclusion: arteries for repair ineffective should not be performed. Direct effective elimination leaks therapy choice when aggressive management indicated. (J Vasc Surg 2002;35:23-9.)
