The Utility of Ultrasound Guidance to Improve the Safety of Closure of Antegrade Common Femoral Artery Access after Lower Limb Revascularization

This study aimed to investigate the feasibility of ultrasound (US)-guidance in reducing adverse event (AE) rates when using Angioseal device during antegrade lower limb angioplasty via common femoral artery access. From December 2016 to November 2022, 1,322 patients were identified, including 1,131 (85.6%) patients who underwent US-guided closure and 191 (14.4%) who underwent non–US-guided closure. Moderate AEs were encountered in 10 (5.2%) patients in the non–US-guided closure group compared to 38 (3.4%) patients in the US-guided closure group (P = .208). Severe AEs were encountered in 4 (2.1%) patients in the non–US-guided closure group compared to 3 (0.3%) patients in the US-guided closure group (P = .01). Overall AEs occurred in 14 (7.3%) patients in the non–US-guided closure group compared to 41 (3.6%) patients in the US-guided closure group (P = .029). Binary logistic regression showed that only non-US guidance was an independent risk factor for the occurrence of severe AEs (P = .008). [Display omitted]
