Acute Basilar Artery Occlusion: Differences in Characteristics and Outcomes after Endovascular Therapy between Patients with and without Underlying Severe Atherosclerotic Stenosis
Fellows’ Journal Club
Sixty-two patients with acute basilar artery occlusion underwent multimodal endovascular therapy with stent-retriever thrombectomy as a first-line endovascular therapy. Patients with underlying intracranial atherosclerotic stenosis underwent additional intracranial angioplasty and stent placement. Underlying intracranial atherosclerotic stenosis was identified at the occlusion site in 15 patients (24.1%). Occlusion in the proximal segment of the basilar artery was more common in patients with intracranial atherosclerotic stenosis (60% versus 6.4%), whereas occlusion in the distal segment was more common in those without it. Patients with and without underlying intracranial atherosclerotic stenosis who underwent endovascular therapy had similar outcomes.
