Endovascular treatment of acute basilar artery occlusion: time to treatment is crucial

Aim To evaluate the safety and efficacy of multimodal endovascular treatment (EVT) of acute basilar artery occlusion (BAO), including bridging therapy [intravenous thrombolysis (IVT) with subsequent EVT], to compare particular EVT techniques and identify predictors of clinical outcome.

Zusammenfassung:Aim To evaluate the safety and efficacy of multimodal endovascular treatment (EVT) of acute basilar artery occlusion (BAO), including bridging therapy [intravenous thrombolysis (IVT) with subsequent EVT], to compare particular EVT techniques and identify predictors of clinical outcome. Materials and methods This retrospective, multi-centre study comprised 72 acute ischaemic stroke patients (51 males; mean age 59.1 ± 13.3 years) with radiologically confirmed BAO. The following data were collected: baseline characteristics, risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, localization of occlusion, time to therapy, recanalization rate, post-treatment imaging findings. Thirty- and 90-day outcomes were evaluated using the modified Rankin scale with a good clinical outcome defined as 0–3 points. Results Successful recanalization was achieved in 94.4% patients. Stepwise binary logistic regression analysis identified the presence of arterial hypertension (OR = 0.073 and OR = 0.067, respectively), National Institutes of Health Stroke Scale (NIHSS) at the time of treatment (OR = 0,829 and OR = 0.864, respectively), and time to treatment (OR = 0.556 and OR = 0.502, respectively) as significant independent predictors of 30- and 90-day clinical outcomes. Conclusion Data from this multicentre study showed that multimodal EVT was an effective recanalization method in acute BAO. Bridging therapy shortens the time to treatment, which was identified as the only modifiable outcome predictor.
