Vascular Access-Site Complications in Chronic Total Occlusion Percutaneous Coronary Intervention

Abstract

Background: Vascular access-site complications (VASC) can occur during chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Methods: We compared the baseline and procedural characteristics, and outcomes of patients with versus without VASC in a large multicenter CTO PCI registry. VASC was defined as any of the following: small hematoma (hematoma = 5 cm), arteriovenous fistula, pseudoaneurysm and acute arterial closure. Results: VASC occurred in 158 of 16,810 CTO PCIs (0.9%). VASC patients were older (67 +/- 11 vs. 64 +/- 10 years, p 0.9) and procedural (82.3% vs. 85.9%, p = 0.2) success, but higher MACE (6.3% vs. 1.9%, p = 7 F were associated with VASC in patients undergoing CTO PCI.
