Our objective was to undertake a comprehensive review of the literature and conduct an analysis of the outcomes of percutaneous endovascular aneurysm repair.

MEDLINE; EMBASE; CINAHL; CENTRAL; the World Health Organization International Clinical Trials Registry; ClinicalTrials.gov; and ISRCTN Register, and bibliographic reference lists were searched to identify all studies providing comparative outcomes of the percutaneous technique for endovascular aneurysm repair. Success rate and access-related complications were defined as the primary outcome parameters. Combined overall effect sizes were calculated using fixed effect or random effects models. We conducted a network meta-analysis of different techniques for femoral access applying multivariate meta-analysis assuming consistency.

Three randomised controlled trials and 18 observational studies were identified. Percutaneous access was associated with a lower frequency of groin infection (p < 0.0001) and lymphocele (p = 0.007), and a shorter procedure time (p < 0.0001) and hospital length of stay (p = 0.03) compared with open surgical access. Moreover, percutaneous endovascular aneurysm repair did not increase the risk of haematoma, pseudoaneurysm, and arterial thrombosis or dissection.

Percutaneous access demonstrates advantages over conventional surgical exposure for endovascular aneurysm repair, as indicated by access-related complications and hospital length of stay. Further research is required to define its impact on resource utilization, cost-effectiveness and quality of life.
