Outcomes after Standalone Use of Gore Excluder Iliac Branch Endoprosthesis for Endovascular Repair of Isolated Iliac Artery Aneurysms.

Abstract：

BACKGROUND:The aim of our study was to describe outcomes of stand-alone use (i.e., without concomitant implantation of an aortic stent graft) of the Gore Excluder iliac branch endoprosthesis (IBE) for elective endovascular repair of isolated iliac artery aneurysms. METHODS:We evaluated all consecutive patients electively treated for isolated iliac artery aneurysms using standalone Gore Excluder IBE (January 2014-December 2018). Early (i.e., 30-day) endpoints were technical success, mortality, major adverse events (MAEs), and major access-site complications. Late endpoints were survival, freedom from aortic-related mortality (ARM), internal iliac artery (IIA) primary patency, IIA branch instability, graft-related adverse events (GRAEs), secondary interventions, endoleaks (ELs), aneurysm sac behavior, and new-onset buttock claudication (BC). RESULTS:A total of 11 consecutive patients (10 men; median age 75 years) were included. The technical success rate was 100%. At 30 days, mortality, MAEs, and major access-site complications were all 0%. Survival and freedom from ARM were 91% and 100%, respectively; only one nonaortic related death was recorded during follow-up. At a median follow-up of 14 months, IIA primary patency, IIA branch instability, and GRAEs were 100%, 0%, and 0%, respectively. No instances of graft migration ≥10 mm were detected. No graft-related secondary interventions were recorded, and 2 patients required a procedure-related secondary intervention 3 months after the index procedure (1 common femoral artery endarterectomy and 1 external iliac artery stenting). Although new-onset type 1 or type 3 ELs were never noted, one patient developed a new-onset type 2 EL. Aneurysm sac regression ≥5 mm was noted in 6 patients (55%), whereas in the remaining ones, the sac size was stable. No instances of new-onset BC were noted. CONCLUSIONS:Use of standalone Gore Excluder IBE for elective endovascular repair of isolated iliac artery aneurysms is a safe, feasible, and effective treatment option. These results may support use of the technique as an effective means of endovascular reconstruction in patients with suitable anatomy.
