PURPOSE
The PercuSurge system is a distal balloon embolic protection device used for carotid artery stenting (CAS). We performed a retrospective study on the prognosis and clinical effects of spasms induced by the PercuSurge GuardWire system (PercuSurge-induced spasm).
MATERIALS AND METHODS
We performed CAS in 118 carotid stenoses using the PercuSurge system. Of the 118 procedures, 31 (26.3%) of the patients experienced PercuSurge-induced spasm, and all underwent postoperative follow-up studies by cerebral angiography and antiplatelet treatment.
RESULTS
On follow-up angiograms obtained a mean of 5.2 months (range 3-10 months) after CAS, all 31 PercuSurge-induced spasms had disappeared, and no delayed stenosis was found at the sites where the spasms had occurred. No ischemic events due to the spasms occurred during a mean follow-up of 13 months (range 3-32 months).
CONCLUSION
In the hands of physicians experienced in endovascular surgery, CAS using the PercuSurge system is a safe method with which to treat patients with carotid stenosis. Our study demonstrated that PercuSurge-induced spasms had no morphological or clinical adverse effects.
目的
PercuSurge系统是一种用于颈动脉支架置入术（CAS）的远端球囊栓塞保护装置。我们对PercuSurge GuardWire系统引起的痉挛（PercuSurge诱导的痉挛）的预后和临床效果进行了一项回顾性研究。
材料与方法
我们使用PercuSurge系统对118例颈动脉狭窄患者进行了CAS。在这118例手术中，31例（26.3%）患者发生了PercuSurge诱导的痉挛，所有患者均接受了术后脑血管造影随访研究和抗血小板治疗。
结果
在CAS术后平均5.2个月（范围3 - 10个月）获得的随访血管造影中，所有31例PercuSurge诱导的痉挛均已消失，且在痉挛发生部位未发现延迟性狭窄。在平均13个月（范围3 - 32个月）的随访期间，未发生因痉挛导致的缺血事件。
结论
在有血管内手术经验的医生手中，使用PercuSurge系统进行CAS是治疗颈动脉狭窄患者的一种安全方法。我们的研究表明，PercuSurge诱导的痉挛没有形态学或临床不良影响。
