Abstract
Percutaneous endovascular aneurysm repair (pEVAR) is commonly utilized and requires the use of suture-mediated closure (SMC) devices to ensure adequate femoral artery hemostasis. Despite the use of such devices, puncture-related complications remain relatively common. We introduced two new adjuncts (pledget reinforcement and tractional compression) along with SMC to reduce such puncture-related complications. The aim of the study was to assess the efficacy and safety of the new adjunct techniques. This retrospective observational cohort study examines the impact of two adjunctive techniques on puncture-related complications compared with the previous year data before this new introduction of adjunct techniques. Sixty-one percutaneous femoral punctures (in 31 patients) utilizing adjunct techniques for closure (the adjunct group) were retrospectively compared with 89 punctures (in 46 patients) closed with standard SMC technique (the standard group). The use of adjunctive techniques led to a significant reduction in overall puncture-related complications (3/61 (4.9%) vs. 20/89 (22.5%), P=0.0106) and the need for emergent surgical repair after failed hemostasis (2/61 (3.3%) vs. 13/89 (14.6%), P=0.037). These novel adjunctive techniques (pledget reinforcement and tractional compression) of SMC for pEVAR reduce puncture-related complications and increase the confidence to offer percutaneous techniques for more patients.
