Abstract: Introduction Endovascular Therapy (EVT) is an effective treatment for Basilar Artery Occlusion (BAO), but selecting the right patients can be challenging. Therefore, a prognostic model such as the Basilar Artery on Computed Tomography Angiography (BATMAN) score may help predict outcomes and guide patient selection. Aim of Study To assess the prognostic value of BATMAN score in predicting good functional status for BAO patients treated with EVT. Methods We conducted a single-centre retrospective cohort study and analysed data from all consecutive patients who underwent EVT for BAO between January 2015 and September 2023. Patients were divided into 2 groups according to BATMAN score: good BATMAN score (gBS) group (values 7-10) and poor BATMAN score (pBS) group (0-6). Primary outcome was good functional status classified as modified Rankin Scale (mRS) score 0-3. Safety outcomes were symptomatic intracranial haemorrhage (sICH) and 90day mortality. Results 55 patients were included in the analysis (23 gBS/32 pBS). Baseline characteristics did not differ significantly between groups. Good functional status occurred in 14 patients (61%) in gBS group and in 9 patients (28%) in pBS group (OR, 3.98; 95% CI, 1.27 to 12.41; P=0.026). sICH occurred in 1 patient (4%) in gBS group and in 3 patients (9%) in pBS group (RR, 0.46; 95% CI, 0.051 to 4.18; P=0.479). Mortality at 90 days was 26% in gBS group and 69% in pBS group (RR, 0.38; 95% CI, 0.18 to 0.78, P=0.0018). Conclusion BATMAN score seems to be a reliable prognostic tool for patients with BAO undergoing EVT. Disclosure of Interest no.
