Outcomes of single versus double Perclose suture device use after transfemoral transcatheter procedures using large-bore arterial access: A meta-analysis and systematic review.

BACKGROUND: In large-bore transfemoral procedures such as transcatheter aortic valve replacement and endovascular aneurysm repair, the comparative effectiveness of single (SP) versus the default double Perclose (DP) strategies for arterial closure remains uncertain. METHODS: We performed a systematic literature search in PubMed, Scopus, Web of Science, and the Cochrane Library from January 2014 to April 2026 to identify studies comparing SP and DP devices for large-bore transfemoral arterial access closure. Outcomes included device/technical success, need for unplanned surgical or catheter-based intervention, 30-day mortality, any vascular complication, major bleeding, arterial dissection, and arterial stenosis. Random-effects meta-analysis using inverse-variance weighting was performed, and heterogeneity was assessed using the I2 statistic. RESULTS: We identified 14 studies published or available between 2015 and 2026, comprising 6487 patients before matching or adjustment (SP 3518; DP 2969). Post-matching adjusted cohorts comprised 5077 patients (SP 2691; DP 2386). Comparing SP with DP, device/technical success was similar (RR 1.02, 95% CI 1.00-1.03; P = 0.07), as was the need for unplanned surgical/catheter intervention (RR 0.77, 95% CI 0.54-1.09; P = 0.14). There were no significant differences in overall vascular complications (RR 0.78, 95% CI 0.59-1.04; P = 0.09), major bleeding (RR 0.83, 95% CI 0.51-1.36; P = 0.46), arterial stenosis (RR 0.81, 95% CI 0.55-1.20; P = 0.30), or 30-day mortality (RR 0.99, 95% CI 0.65-1.50; P = 0.96). However, SP was associated with a lower risk of arterial dissection (RR 0.32, 95% CI 0.15-0.70; P = 0.004). CONCLUSION: In large-bore transfemoral transcatheter procedures, a single Perclose strategy was associated with a lower risk of arterial dissection compared to double Perclose and no significant difference for other major outcomes and complications.
