This study states that Randomised controlled trials (RCTs) that compared percutaneous and cutdown endovascular aneurysm repair (EVAR) were considered. Pooled effect estimates were calculated using the odds ratio (OR), risk difference, or mean difference (MD) and 95% confidence interval (CI). The Mantel–Haenszel or inverse variance statistical method was used as appropriate. Trial sequential analysis was performed to quantify the available evidence and control for the risk of type 1 and type 2 error. Risk of bias was assessed with the revised tool developed by Cochrane and the quality of evidence was graded using the GRADE system (Grades of Recommendation, Assessment, Development and Evaluation).
Four RCTs were identified, reporting a total of 368 patients and 530 access sites. Meta-analysis showed no difference in access site complications or infection, post-operative bleeding/haematoma, access related arterial injury, femoral artery occlusion, pseudo-aneurysm, or peri-operative mortality between percutaneous and cutdown EVAR. Seroma/lymphorrhoea was significantly less frequent after percutaneous EVAR.
