Hemostasis control after femoral percutaneous approach: A systematic review and meta-analysis

Hemostasis control after percutaneous endovascular procedures through the femoral approach remains challenging for catheterization laboratory nurses, given method variability.To summarize the available evidence on vascular devices efficacy dedicated to hemostasis control compared to the extrinsic compression after percutaneous procedures in the femoral vein or artery.A systematic review with meta-analysis of randomized clinical trials was conducted. We compared different hemostasis methods in adult patients who underwent diagnostic and/or therapeutic procedures through femoral access. The databases searched were PubMed, Embase, CINAHL and Cochrane CENTRAL, and updated on 03/2022. The outcomes included hematoma, pseudoaneurysm, bleeding, minor and major vascular complication, time to hemostasis, device failure, and manual compression repetition. The risk of bias was assessed using the Cochrane Risk of Bias Tool 1.0. Pooled effect sizes on continuous, categorical and proportion variables were estimated with the random effects model. The continuous variables were summarized as the difference between means weighted by the inverse of variance (WMD), and the categorical ones by the summary of relative risks (RR), estimated by the DerSimonian and Laird method. The Freeman-Tukey method was used to estimate the summary effect of proportions.Fifty articles were included in the systematic review. When compared to extrinsic compression, vascular closure devices resulted in a relative risk reduction (RRR) for hematoma: RR 0.82 [95%CI 0.72 to 0.94] and in shorter time to hemostasis WMD -15.06 min [95%CI -17.56 to -12.56]; no association was observed between interventions with vascular closure devices and extrinsic compression for pseudoaneurysm, bleeding, minor and major vascular complications. Compared to extrinsic compression, sealant or gel type devices were compatible with a RRR for hematoma: RR 0.73 [95%CI 0.59 to 0.90]; and metal clip or staple type devices for pseudoaneurysm: RR 0.48 [95%CI 0.25 to 0.90]; and major vascular complication: RR 0.33 [95%CI 0.17 to 0.64]. For each 100 observations, the device failure rate for metal clip or staple was 3.28% [95%CI 1.69 to 6.27]; for suture 6.84% [95%CI 4.93 to 9.41]; for collagen 3.15% [95%CI 2.24 to 4.41]; and for sealant or gel 7.22% [95% CI 5.49 to 9.45].Vascular closure devices performed better in hemostasis control. The certainty of the evidence was rated as very low to moderate.PROSPERO CRD42019140794.
