Abstract

Objective: Transradial access has recently been gaining more popularity in various neurointerventional procedures. To this day, a systematic review and meta-analysis investigating the outcomes of transradial access for mechanical thrombectomy in acute stroke have not been performed. Methods: PubMed, Embase, and Scopus databases were systematically searched. Studies published in the last ten years reporting on the use of transradial access for acute stroke intervention were eligible. The DerSimonian–Laird random effects model was used, and the primary endpoints included puncture to reperfusion time, end mRS, TICI reperfusion, mortality, and access site complications. Results: A total of 515 records were identified. Fourteen observational studies reported on the use of radial access for thrombectomy, with 10 of these studies (n = 309) included in the meta-analysis. Mean puncture to reperfusion time associated with the transradial access was 46.864 ± 6.601 min. Favorable end mRS of ≤ 2 was reported in 37.1 % ± 7.3 % of patients. TICI ≥ 2B was achieved in 84.6 % ± 3.4 % of patients. All-cause mortality was observed in 9.3 % ± 4.8 % of patients. Transradial access had low complications with only 1.4 % ± 0.7 % of stroke cases. When the transradial studies were compared to the contemporary randomized clinical trials using the standard transfemoral access, no significant differences were found in all of these primary outcomes. Conclusion: This meta-analysis study demonstrates that transradial access for mechanical thrombectomy in acute stroke may be a feasible and safe alternative. Future prospective studies are needed to validate these results.
