Objective: The aim of this study is to compare the outcomes of percutaneous femoral closure with the Prostar XL for endovascular aneurysm repair (EVAR) to those of open femoral cutdown, and to evaluate factors which may predict the failure of percutaneous closure. Methods: Patients undergoing endovascular aneurysm repair for an infrarenal abdominal aortic aneurysm between 2005 and 2013 were included. Patient characteristics, anatomic femoral artery measurements, and postoperative complications were recorded retrospectively. Operator experience was defined with a cut-off point of >30 Prostar XL closures performed. Comparisons were made per access site. Results: A total of 443 access sites were included, with percutaneous closure used in 257 cases (58.0%) and open cutdown in 186 cases (42.0%). The complication rate was 2.7% for the percutaneous and 4.3% for the open cutdown group (P =.482). No significant differences between groups were found with respect to 30-day mortality, wound infections, thrombosis, seromas, or bleeding complications. Fourteen failures (5.4%) of percutaneous closure occurred. The success rates were similar for experienced and unexperienced operators (94.2% vs 95.5%, P =.768). Renal insufficiency was more common in the failed than in the successful percutaneous closure group (64.3% vs 24.7%, P =.003). Common femoral artery calcification or diameter, BMI, sheath size, or operator experience did not predict failure. No further complications were seen in follow-up CT at 1-3 years postoperatively. Conclusion: The use of the Prostar XL is safe compared to open cutdown. The success rate is 94.6%. Operator experience, sheath size, obesity, or femoral artery diameter or calcification do not appear to predict a failure of percutaneous closure. Complications seem to occur perioperatively, and late complications are rare.
