AIM: The aim of this paper was to report outcomes of endovascular aneurysm repair with percutaneous femoral access (pEVAR) using Prostar XL and Proglide closure systems (Abbot Vascular, Santa Clara, CA, USA), from the multicenter Italian Percutaneous EVAR (IPER) registry.
METHODS: Consecutive patients affected by aortic pathology treated by EVAR with percutaneous access (pEVAR) between January 2010 and December 2014 at seven Italian centers were enrolled in this multicenter registry. All the operators had an experience of at least 50 percutaneous femoral access procedures. Data were prospectively collected into a dedicated online database including patient’s demographics, anatomical features, intra- and postoperative outcomes. A retrospective analysis was carried out to report intraoperative and 30-day technical success and access-related complication rate. Uni- and multivariate analyses were performed to identify factors potentially associated with an increased risk of percutaneous pEVAR failure.
RESULTS: A total of 2381 accesses were collected in 1322 patients, 1249 (94.4%) male with a mean age of 73.5±8.3 years (range 45-97). The overall technical success rate was 96.8% (2305/2381). Major intraoperative access-related complications requiring conversion to surgical cut-down were observed in 3.2% of the cases (76/2381). One-month pEVAR failure-rate was 0.25% (6/2381). Presence of femoral artery calcifications resulted to be a significant predictor of technical failure (OR: 1.69; 95% CI: 1.03-2.77; P=0.036) at multivariate analysis. No significant association was observed with sex (P=0.28), obesity (P=0.64), CFA diameter (P=0.32), level of CFA bifurcation (P=0.94) and sheath size >18 F (P=0.24). The use of Proglide was associated with a lower failure rate compared to Prostar XL (2.5% vs. 3.3%) despite not statistically significant (P=0.33).
CONCLUSION: The results of the IPER registry confirm the high technical success rate of percutaneous EVAR when performed by experienced operators, even in presence of demanding anatomies. Femoral calcification represents the only predictor of percutaneous access failure.
