Feasibility, efficacy, and safety of sheathless transradial mechanical thrombectomy in acute ischemic stroke: A meta-analysis.
Introduction: Mechanical thrombectomy (MT) is the standard of care for large vessel occlusions (LVO) in acute ischemic stroke (AIS), traditionally performed using transfemoral access (TFA). However, the sheathless transradial approach (sTRA) has emerged as a viable alternative, particularly for patients with complex vascular anatomies.
Objectives: This systematic review and meta-analysis aim to evaluate the feasibility, efficacy, and safety of sTRA in MT for AIS.
Methods: We conducted a systematic review and meta-analysis following PRISMA guidelines, including observational studies that reported on MT using sTRA. Primary outcomes included the proportion of successful reperfusion (modified Treatment in Cerebral Infarction [mTICI] grade 2b-3), crossover rates from radial to femoral access, and symptomatic intracerebral hemorrhage (sICH). Secondary outcomes assessed were minor access site-related complications.
Results: A total of four studies were included, comprising 138 patients who underwent MT with sTRA. The pooled analysis revealed a high rate of successful reperfusion (97%; 95% CI: 95-100%), with a low crossover rate to TFA (3%; 95% CI: 0-7%). The incidence of sICH was low, at 4% (95% CI: 0-8%), and minor access site-related complications occurred in 5% of patients (95% CI: 2-9%).
Conclusion: This meta-analysis demonstrates that sTRA is a feasible and effective approach for MT in AIS, with a favorable safety profile. The technique offers high recanalization rates, low complication rates, and minimal need for crossover to TFA. Future randomized controlled trials comparing MT with sTRA and TFA are needed to confirm these results and refine patient selection criteria for this approach. Despite encouraging results, the small number of included studies and their observational design limit the generalizability of the findings. Therefore, further comparative and randomized trials are needed to validate these outcomes.

Neuroradiology aims to provide state-of-the-art medical and scientific information in the fields of Neuroradiology, Neurosciences, Neurology, Psychiatry, Neurosurgery, and related medical specialities. Neuroradiology as the official Journal of the European Society of Neuroradiology receives submissions from all parts of the world and publishes peer-reviewed original research, comprehensive reviews, educational papers, opinion papers, and short reports on exceptional clinical observations and new technical developments in the field of Neuroimaging and Neurointervention. The journal has subsections for Diagnostic and Interventional Neuroradiology, Advanced Neuroimaging, Paediatric Neuroradiology, Head-Neck-ENT Radiology, Spine Neuroradiology, and for submissions from Japan. Neuroradiology aims to provide new knowledge about and insights into the function and pathology of the human nervous system that may help to better diagnose and treat nervous system diseases. Neuroradiology is a member of the Committee on Publication Ethics (COPE) and follows the COPE core practices. Neuroradiology prefers articles that are free of bias, self-critical regarding limitations, transparent and clear in describing study participants, methods, and statistics, and short in presenting results. Before peer-review all submissions are automatically checked by iThenticate to assess for potential overlap in prior publication.
