Abstract

<abstract xml:lang="en" abstract-type="author" id="abs0010"> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title id="sectitle0010">Objective</title> <p id="abspara0010">To identify predictors of failure in percutaneous endovascular aneurysm repair (P-EVAR) using the Prostar XL Percutaneous Vascular Surgery Device (Abbot Vascular, Santa Clara, CA, USA) and the need for conversion to conventional femoral cutdown (O-EVAR).</p> </sec> <sec> <title id="sectitle0015">Methods</title> <p id="abspara0015">Consecutive patients who underwent P-EVAR with the Prostar XL device between January 2009 and April 2012 were included in this series. Patients with a circular calcified common femoral artery (CFA) on computed tomography angiography were operated using O-EVAR and were therefore excluded. To identify predictors of success of closure in P-EVAR, artery characteristics, sheath size used, and comorbidities were analyzed in a univariate logistic regression model.</p> </sec> <sec> <title id="sectitle0020">Results</title> <p id="abspara0020">Percutaneous access was achieved in 154 femoral access sites with conversion to O-EVAR was needed in 10 (6.5%). Significant predictors of conversion included sheath size (continuous, relative risk [RR] 1.50, <italic>p</italic> < .03) and the ratio between sheath size and CFA diameter >0.75 (RR 8.93, <italic>p</italic> < .01). Variables such as calcification quantity scores, CFA diameter, body mass index, and comorbidities were not significant.</p> </sec> <sec> <title id="sectitle0025">Conclusion</title> <p id="abspara0025">The data demonstrate that sheath size, in particular, combined with CFA diameter predicts failure of closure in P-EVAR using the Prostar XL device. This ratio can be utilized to help in decision making with regard to the EVAR approach. A ratio of >0.75 would favor a primary open groin approach.</p> </sec> </abstract>
