EVT in Acute Basilar Artery Occlusion With Large Infarction Core

The vascular access route is selected based on the patient's anatomical characteristics and operator discretion. Endovascular treatment (EVT) procedures must adhere to each participating center's standardized operating protocols. Upon confirmation of vascular occlusion, EVT may be performed using devices approved by China's National Medical Products Administration (NMPA). Based on lesion-specific features and operator judgment, permissible techniques include stent retriever thrombectomy, aspiration thrombectomy, balloon angioplasty with or without stenting, or intra-arterial thrombolysis. Investigational devices are strictly prohibited.
