Among the 213 enrolled patients, 210 patients (98.6%) obtained successfully revascularization and 206 patients (96.7%) had good revascularization after stenting. The extent of stenosis before and after intervention was 86.3 ± 6.8% and 9.1 ± 3.7%, respectively. Within 90 days after stenting, 10 patients (4.7%) experienced primary endpoint events, including 4 cases (4.2%) in the intracranial vertebral artery (V4) group and 6 (5.1%) in basilar artery (BA) group. Among them, 2 (2.1%) and 3 cases (2.5%) of ischemic stroke in V4 and BA group, respectively; and 2 (2.1%) and 2 (1.7%) cases of TIA in V4 and BA group, respectively. One (0.8%) case in the BA group dead because of the acute stent occlusion resulted in the top of the basilar syndrome. Six patients (2.8%) experienced adverse events, including 2 (2.1%) and 4 (3.4%) cases of groin hematoma in the V4 and BA group, respectively. No cases of hemorrhagic...
