Complication of Stenting in Intracranial Arterial Stenosis
Abstract:
Introduction
To evaluate the perioperative complications and long-term restenosis rates following percutaneous transluminal angioplasty and stenting (PTAS) in patients with intracranial atherosclerotic stenosis (ICAS).Methods
A retrospective analysis was performed on the clinical data of 102 ICAS patients (103 cases of stenosis) who underwent PTAS. The perioperative complications and long-term restenosis rates were analyzed.Results
The success rate of PTAS was 100%. Six patients (5.83%, 6/103) had perioperative complications. Six cases (6.52%, 6/92) of restenosis occurred and one patient (1.09%) died. Five of the 6 restenosis cases (5.43%) occurred in the blood-supplying region and were associated with ischemic symptoms and one patient (1.09%) had no ischemic symptom. The postoperative restenosis rates at 6, 6 12, and 12 74 months were 3.26%, 2.56%, and 2.38%, respectively. The postoperative restenosis rates had a significant difference between the residual stenosis rate ≥ 20% and Conclusions
The vasospasm, arterial dissection, arterial occlusion and acute thrombosis are common perioperative complications following PTAS in patients with ICAS. The medium- and long-term postoperative restenosis rate is low. Age is the risk factor for postoperative restenosis.Keywords:
