高龄老年人症状性颈动脉狭窄与颈动脉内膜切除术(附3例临床报告)

The Effectiveness of Carotid Endarterectomy in Advanced Age Patients with Symptomatic Carotid Artery Narrowing

目的 探讨高龄老年人症状性颈动脉狭窄的诊断、狭窄程度与颈动脉内膜切除术的有效性。方法 回顾追踪 3例高龄老年人颈动脉内膜切除术前后临床缺血发作症状、颈动脉超声、头颅及颈部磁共振血管造影的变化。结果 2例患者经颈动脉内膜切除术后 2、5年内缺血发作缓解 ,颈动脉检查狭窄消失 ,1例患者术后 1个月切除部位形成血栓再次出现狭窄。结论 老年人症状性高度颈动脉狭窄者可从手术中获益。

Objective To investigate the diagnosis of the symptomatic carotid artery stenosis and the relationship between the degree of stenosis and effectiveness of carotid endarterectomy in advanced age. Methods The changes in clinical symptoms,carotid artery ultrasound,magnetic resonance angiography (MRA) of brain and cervical region before and after carotid endarterectomy of 3 advanced age patients were reviewed. Results The symptoms of cerebral ischemia in 2 cases were vanished for 2 and 5 years after operation respectively,the examinations of their carotid artery showed disappearance of the stenosis. The thrombosis and restenosis were found intheplaceofendarterectomyin1patientonemonthafter operation. Conclusions Thecarotid endarterectomy is beneficial to the treatment advanced age patients with severe carotid artery stenosis.
