Thrombectomy in Posterior Circulation Tandem Occlusions: Multicenter Comparative Analysis of Procedural Techniques and Predictors of Clinical Outcomes

The authors aimed to evaluate the outcomes of thrombectomy in patients with posterior circulation tandem occlusions (TOs) across multiple centers. They found that thrombectomy was feasible and effective, with successful reperfusion achieved in 88.5% of patients and favorable functional outcomes associated with a distal-first strategy. Additionally, factors such as hyperglycemia, hypertension, and higher baseline NIHSS scores predicted unfavorable outcomes, while successful reperfusion and prestroke antithrombotic use were linked to better outcomes.
