AIM: We assessed the safety and effectiveness of the Enterprise stent in treating @entity4522 ( @entity4522 ). MATERIAL AND METHODS: This was a retrospective study conducted with 60 consecutive @entity1 with 62 @entity4522 lesions who received the Enterprise stent at the Department of Neurosurgery, Second Hospital of Shandong University between June 2012 and January 2014. All @entity1 were assessed using the modified Rankin scoring system at discharge. Clinical follow-ups and digital subtraction angiography (DSA) were performed at 1, 3, 6 and 12 months postoperatively. RESULTS: There were 42 @entity1 and 18 @entity1 with a mean age of 56.8  8.0 years. Fourteen lesions (22.6%) were at the anterior and 48 (77.4 %) were at the posterior circulation. The mean stenosis rate was 76.3  12.7%. The mean stenotic vessel length was 7.7  2.0 mm. The technical success rate was 100%. The mean post-stent residual stenosis rate was 22.8  4.8%. Five @entity1 (8.3%) had perioperative complications, but no disability or mortality occurred within 30 days. The mean follow-up duration was 6.2 months. DSA was used to evaluate 45 lesions (72.6%) six months postoperatively: 6 (13.3%) had postoperative restenoses, 2 at the anterior circulation, and 4 at the posterior circulation. Of these 6, 4 (66.7%) were immediate residual stenoses after stenting. The residual stenosis rate was identified as a risk factor for @entity256 . Five (8.3%) @entity63 events, consistent with the @entity455 , occurred. CONCLUSION: Application of the Enterprise stent was safe and efficacious. The technical success rate was high while the perioperative complication rate was low.
