BACKGROUND
Proper patient selection criteria for treatment of carotid chronic total occlusion (CTO) are unclear. This study was designed to predict procedure successful rate and 1-year patency after carotid artery stenting (CAS) for carotid CTO using pre-procedural CTA.
METHODS
Patients with CTO detected on CTA who underwent recanalization within 3months were divided into those with occlusions at (or distal to) the clinoid segment of the internal carotid artery (group A) and those with occlusions proximal to the clinoid segment (group B) and outcomes were compared between groups.
RESULTS
Technical success rates, major complications, and re-occlusions within 1-year were 52%, 22%, 91% in group A (N=23), and 89%, 0%, 0% in group B (N=19), respectively. Diabetes was more frequent in group A (43%) compared with group B (11%).
CONCLUSION
CTA may play a role in predicting successful rate and 1-year patency for endovascular recanalization in carotid CTO.
背景
治疗颈动脉慢性完全闭塞（CTO）的恰当患者选择标准尚不清楚。本研究旨在利用术前CTA预测颈动脉CTO患者行颈动脉支架置入术（CAS）后的手术成功率和1年通畅率。
方法
CTA检测出CTO且在3个月内行再通治疗的患者被分为颈内动脉床突段（或其远端）闭塞的患者（A组）和床突段近端闭塞的患者（B组），并比较两组的结局。
结果
A组（n = 23）的技术成功率、主要并发症和1年内再闭塞率分别为52%、22%、91%，B组（n = 19）分别为89%、0%、0%。A组（43%）糖尿病患者比B组（11%）更常见。
结论
CTA可能在预测颈动脉CTO血管内再通的成功率和1年通畅率方面发挥作用。
