Abstract

Background: Vascular closure devices have been used to achieve hemostasis of percutaneous access sites following endovascular procedures, with reported decreased time for arterial control as well as decreased time to ambulation. We sought to determine rates and risk factors of postoperative bleeding complications and failures using these devices from a single institution experienced in the use of vascular closure devices.

Methods: All patients undergoing arterial endovascular procedures with percutaneous access between March 2010 and October 2015 at a single institution were identified and analyzed (n = 894). Patients undergoing endovascular aneurysm repair, open access, venous procedures, or upper extremity access were excluded. Comparison groups were formed between those using the Mynxgrip® (Mynx), Angio-Seal™, Perclose® vascular closure devices and manual pressure (MP). Patient demographics, intraoperative data, and postoperative complications were compared.

Results: A total of 615 (69%) patients received Mynx, 165 other vascular closure devices (VCD) ([14%] Perclose, 44 [4%] Angio-Seal), and 114 (13%) MP. MP patients were more likely to be diagnostic angiogram with smaller sheaths, while VCD patients were more likely to be interventions with larger sheaths. Univariate analysis identified age, atrial fibrillation, intervention (as opposed to diagnostic), and sheath size >5F associated with postoperative bleeding (P < 0.05), and in backward, logistic regression analysis, sheath size, age, and renal failure were independent predictors of the same.

Conclusions: Use of vascular closure devices has a low rate of bleeding complication, device failure, and need for operative repair. Bleeding is associated with increased age, interventional procedure, and end-stage renal disease. Mynx, Perclose, and Angio-Seal have similar rates of complications. Use of these devices are a safe option for groin vessel closure.
