This study was performed to explore the effect of the aortic arch type on technical indicators in patients undergoing carotid artery stenting (CAS).
The data of 224 consecutive patients who underwent unilateral CAS from January 2011 to December 2012 were retrospectively analyzed. The requirement for placement of the guiding catheter into the common carotid artery with assistance of an angiographic catheter, fluoroscopy time, contrast agent dose, and adverse events were recorded.
The fluoroscopy time was significantly longer and the contrast agent dose was significantly higher in patients with Type III than Type I and II arches. Significantly more patients with Type III than Type I and II arches required placement of the guiding catheter with assistance of an angiographic catheter (46.2% vs. 15.0%, respectively). The procedural success rate was significantly lower in patients with Type III than Type I and II arches (96.2% vs. 100.0%, respectively). The incidence of death, myocardial infarction, and all types of stroke was significantly higher in patients with Type III than Type I and II arches (7.7% vs. 1.7%, respectively).
The aortic arch type is an important influential factor in CAS. Type III arches are associated with more difficulties and complications.
本研究旨在探讨主动脉弓类型对接受颈动脉支架置入术（CAS）患者技术指标的影响。
回顾性分析2011年1月至2012年12月期间连续接受单侧CAS的224例患者的数据。记录在血管造影导管辅助下将引导导管置入颈总动脉的需求、透视时间、造影剂剂量和不良事件。
III型主动脉弓患者的透视时间明显长于I型和II型主动脉弓患者，造影剂剂量也明显更高。与I型和II型主动脉弓患者相比，III型主动脉弓患者需要在血管造影导管辅助下放置引导导管的人数明显更多（分别为46.2%和15.0%）。III型主动脉弓患者的手术成功率明显低于I型和II型主动脉弓患者（分别为96.2%和100.0%）。III型主动脉弓患者的死亡、心肌梗死和所有类型中风的发生率明显高于I型和II型主动脉弓患者（分别为7.7%和1.7%）。
主动脉弓类型是CAS的一个重要影响因素。III型主动脉弓与更多的困难和并发症相关。
