Observational StudyAcute Stroke Treatment in Patients with Basilar Artery Occlusion: A Single-Center Observational Study.
Acute ischemic stroke (AIS) due to basilar artery occlusion (BAO) represents 1-4% of all ischemic strokes. BAO results in strokes associated with a high risk of a poor functional outcome and, in 86-95% of the untreated cases, it results in death because of the vital cerebral structures involved. Diagnosis can be delayed because of the variability in presenting symptoms, and acute treatment is often attempted even beyond 6 h from symptoms onset because of the high risk of a fatal prognosis. ⋯ In our study, we found that younger age, low NIHSS score at admission, and high pc-ASPECTS, but not onset to treatment time, are associated with a favorable clinical outcome. Transferred patients did not have a significantly poorer outcome. These findings confirm that acute stroke treatment improves clinical outcome in BAO patients, in spite of a delayed diagnosis and an extended therapeutic window, considering lesion volume and localization in DWI MRI.
