Abstract: Objective To assess the safety and efficacy of enterprise stent in the treatment of atherosclerotic vertebral-basilar arterial stenosis. Methods A retrospective study was performed in patients who received enterprise stent in the Department of Neurosurgery, Second Hospital of Shandong University during Jan. 2012 and June 2014. Patients were prescribed with medication of clopidogrel 75 mg/d and aspirin 300 mg/d at least 3 days preoperatively. The observation indexes, clinical follow-ups and digital subtraction angiography (DSA) performed in month 1, 3, 6 and 12 postoperatively were collected and reviewed. Results Of the 46 patients with 48 lesions, 33 (71.7%) were men and 13 (28.3%) were women, 28 lesions (58.3%) were at the basilar artery, 15 (31.3%) were at the left vertebral artery, and 5 (10.4%) were at the right vertebral artery. The technical success rate was 100%. Altogether 4 patients (8.7%) developed perioperative complications. DSA examination of 35 lesions 6 months postoperatively showed 5 cases (14.3%) had postoperative restenoses. And 5 (10.9%) ischemic events occurred during the follow-up. Conclusion Application of enterprise stent is safe and efficacious, with high technical success rate and low perioperative complication rate.
