A novel radiological score on digital subtraction angiography predicts prognosis for acute basilar artery occlusion treated with endovascular thrombectomy: a two-center retrospective study.

ABSTRACT:

Background

Acute basilar artery occlusion (BAO) carries high risks of disability and mortality. While endovascular thrombectomy (EVT) improves outcomes, reliable prognostic tools are needed. This study aimed to evaluate the prognostic value of the novel Basilar Artery and Posterior Circulation Collaterals (BAPCOR) score on digital subtraction angiography (DSA) for predicting clinical outcomes after EVT in acute BAO.

Methods

A retrospective analysis was conducted on consecutive acute BAO patients treated with EVT at two comprehensive stroke centers (October 2020-January 2024). The BAPCOR score (15-point DSA-based system) assessed thrombus burden and posterior circulation collateral status. Successful recanalization was defined as modified Thrombolysis in Cerebral Infarction (
