Abstract

Background Mechanical thrombectomy (MT) is a well-established treatment for acute ischemic stroke (AIS) due to large vessel occlusion (LVO). However, its role in cervical artery dissection-related (CeAD) LVO remains debated due to anatomical complexities and procedural challenges. This systematic review and meta-analysis aims to evaluate the safety, efficacy, and clinical outcomes of MT in patients with AIS due to CeAD-related LVO compared with other AIS etiologies. Methods PubMed, Embase, and Scopus were systematically searched from inception to March 2025. Comparative observational studies evaluating the use of MT in adult patients with AIS due to LVO were included, specifically those comparing outcomes in patients with CeAD versus non-CeAD etiologies. Results MT for CeAD-related AIS showed no statistically significant difference in successful recanalization compared with non-CeAD cases (OR 0.81 (95% CI 0.63 to 1.04), P=0.10). However, patients with CeAD-related AIS had significantly higher rates of 90-day functional independence (modified Rankin Scale score 0–2) (OR 2.17 (95% CI 1.55 to 3.05), P<0.01) and lower 90-day mortality (OR 0.34 (95% CI 0.22 to 0.53), P<0.01). Rates of distal embolization (OR 1.60 (95% CI 0.69 to 3.70), P=0.27), symptomatic intracranial hemorrhage (OR 0.84 (95% CI 0.51 to 1.38), P=0.49), or iatrogenic dissection (OR 1.58 (95% CI 0.59 to 4.22), P=0.36) did not differ significantly between patient groups. Conclusions MT in patients with CeAD-related LVO is safe, effective, and associated with improved functional outcomes and lower mortality compared with patients with non-CeAD acute ischemic causes. © Author(s) (or their employer(s)) 2025.
