摘要
目的采用球囊导管(BGC)近端闭塞颈总动脉(CCA)进行颈动脉支架植入术(CAS)是一种简单的近端保护方法,可防止远端栓塞,但至少需要8 French (F)系统。7f Optimo BGC是最小的BGC,内腔直径为0.071英寸,允许5f颈动脉支架通过。我们回顾性地研究了7f Optimo BGC联合远端过滤器的临床结果和CAS的安全性。材料与方法对100例颈动脉狭窄患者采用7f Optimo BGC和远端过滤器联合保护进行CAS治疗。BGC分别从85例和15例患者的股动脉和桡动脉进行导航。结果7 F Optimo BGC在所有患者中均顺利导航进入CCA,技术成功率为100%。1例(1%)患者在手术后30天内出现任何死亡、中风或心肌梗死的主要不良事件。术后弥散加权磁共振成像显示21%的患者高信号,所有患者无症状。结论7f Optimo是采用近端保护系统实现CAS的最小BGC。联合使用7f Optimo BGC和远端过滤器对BGC导航和远端栓塞保护是有效的。
Carotid artery stenting using a 7 French Optimo balloon guide catheter combined with a distal filter.
ObjectivesCarotid artery stenting (CAS) by proximal occlusion of the common carotid artery (CCA) using a balloon guide catheter (BGC) is a simple proximal protection method to prevent distal embolism, however, it requires at least an 8 French (F) system. A 7 F Optimo BGC is the smallest BGC with an inner lumen diameter of 0.071 inches, and which permits the passage of a 5 F carotid stent. We retrospectively investigated the clinical results and the safety of CAS by using a 7 F Optimo BGC combined with a distal filter.Materials and MethodsOne-hundred carotid arterial stenosis patients were treated with CAS using combined protection of a 7 F Optimo BGC and a distal filter. The BGC was navigated from the femoral and radial arteries in 85 and 15 patients, respectively.ResultsThe 7 F Optimo BGC was successfully navigated into the CCA in all patients, and the technical success rate of CAS was 100%. Major adverse events of any death, stroke, or myocardial infarction within 30-day after the procedure were observed in one (1%). Post-procedural diffusion-weighted magnetic resonance imaging revealed high signals in 21% of the patients, all of whom were asymptomatic.ConclusionsThe 7 F Optimo is the smallest BGC to achieve CAS using a proximal protection system. The combined use of a 7 F Optimo BGC and a distal filter is effective for navigating the BGC and distal embolic protection.
