Mechanical Thrombectomy in Basilar Artery Occlusion : Presence of Bilateral Posterior Communicating Arteries is a Predictor of Favorable Clinical Outcome.

The use of MT for BAO is safe with high rates of successful reperfusion. Aside from baseline NIHSS and incomplete vessel occlusion, both known predictors of favorable outcome in anterior circulation events, we found that collateral flow based on the presence or absence of PcoAs had a decisive prognostic impact.
