目的探讨经桡动脉入路行颈动脉狭窄支架成形术的适应证和优势。方法经桡动脉入路在颈内动脉岩部放置阻塞球囊,对38例颈动脉粥样硬化性狭窄患者行支架置入术。其中有症状者29例,无症状者9例。术前均行颈动脉数字减影血管造影(DSA)、脑实质血管DSA、颈动脉多普勒超声及头部MR I等检查。结果术后患者均复查颈动脉DSA和脑实质血管DSA,显示脑部供血均有明显改善,其患侧颈内动脉、皮质下血管显影时间较术前提前0.3~0.8 s,颅内血管血流经过时间缩短0.4~0.7 s。短暂性脑缺血发作(TIA)症状消失。全组无手术死亡病例,无并发症。随访3~15个月,无再狭窄患者。结论当经股动脉入路为相对禁忌时,经桡动脉入路是颈动脉狭窄支架成形术值得选择的一种入路。
Objective To explore the indications and advantages of transradial approach for carotid artery stenting. Methods The obstruction balloon was placed on the rock of internal carotid artery via radial artery approach, and 38 patients with carotid atherosclerosis were treated with stenting. Among them, 29 cases were symptomatic and 9 cases were asymptomatic. Preoperative carotid digital subtraction angiography (DSA), brain parenchymal vascular DSA, carotid artery Doppler ultrasound and head MRI and other tests. Results All patients underwent carotid artery DSA and cerebral parenchymal vessels DSA. The blood supply to the brain was significantly improved. The ipsilateral internal carotid artery and subcortical vessels developed 0.3 ~ 0.8 s earlier than preoperative, and intracranial vascular blood flow Shorten the time 0.4 ~ 0.7 s. Transient ischemic attack (TIA) symptoms disappear. No case of surgical deaths, no complications. Follow-up 3 to 15 months, no restenosis patients. Conclusions Transradial approach is a worthy choice for stenting of carotid artery stenosis when the transsphenoidal approach is relatively contraindicated.
