Vascular Procedures and Complications

To retrospectively analyze the efficacy and midterm results of endovascular aneurysm repair (EVAR) with a tubular stent-graft using 2 different implantation techniques.Between November 2004 and September 2007, 53 patients (49 men; mean age 68.5+/-8.6 years, range 40-80) were treated with the EndoFit tube stent-graft. The majority (45, 85%) were treated using the trombone technique, in which 2 tubular aortoaortic endografts were deployed with 4 to 8 cm of overlap. This subgroup was compared to the 8 patients who received single tube grafts.Technical and procedural success were 100%; perioperative mortality was 0%. Operative results were similar for patients treated with 1 graft versus those treated with the overlapping trombone technique. The overall device-related complication rate was significantly lower for patients treated with the trombone technique (11% versus 75%, p<0.001). Mean follow-up was 24 months (range 6-36). Endoleak type II occurred in 3 (5.7%) cases. Three (5.7%) patients died, 1 from an aortoduodenal fistula secondary to a proximal type I endoleak and 2 from acute myocardial infarction.The tubular EndoFit device appears both safe and effective in terms of midterm clinical outcome, especially when the trombone technique is utilized. It compares favorably with previously reported EVAR results.
