title: Percutaneous endovascular abdominal aortic aneurysm repair.
abstract: In this prospective, nonrandomized study, we compared outcome with percutaneous femoral artery closure to that with open femoral arteriotomy in 95 patients who underwent endovascular AAA repair. Devices were introduced using 22 Fr and/or 16 Fr sheaths. The 8 Fr/10 Fr Perclose devices (Perclose Inc., Redwood City, CA) were used in an off-label "preclose technique." Thirty-three patients had bilateral open femoral arteriotomies, 44 patients had bilateral attempted percutaneous closure, and 18 patients had open femoral arteriotomy on one side and attempted percutaneous closure on the other side. Percutaneous closure was successful in 85% (47/55) of 16 Fr sheaths and 64% (29/45) of 22 Fr sheaths (p < 0.027). Bilateral percutaneous closure was successful in 63% (28/44) of patients. Conversion to open femoral arteriotomy due to bleeding occurred in 24 of 106 percutaneous attempts. There were no dissections, arterial thromboses, or pseudoaneurysms associated with percutaneous arterial closure. Wound complications were seen in 3.6% (3/84) of open arteriotomies and 0.9% (1/106) of all percutaneous attempts and arterial closures (p > 0.05). Gender, previous femoral access, obesity, and iliac occlusive disease were not predictive of percutaneous failure. Procedural success for percutaneous AAA repair is affected by sheath size. Devices delivered through 16 Fr or smaller sheaths will have successful femoral artery closure rates of at least 85%.
