研究证明颈动脉粥样硬化斑块造成血管狭窄及闭塞是引起缺血性脑卒中的重要原因。颈动脉内膜切除术的目的是切除颈动脉粥样硬化斑块,解除颈总动脉及颈内动脉的狭窄和阻塞。颈动脉内膜切除术(CEA)因其较低的并发症及肯定的疗效已成为目前预防和治疗缺血性脑血管病的最有效手段。? Studies have shown that carotid atherosclerosis caused by vascular stenosis and occlusion is an important cause of ischemic stroke. The purpose of carotid endarterectomy is to remove the carotid atherosclerotic plaque and relieve the stenosis and obstruction of the common carotid and internal carotid arteries. Carotid endarterectomy (CEA) has become the most effective method for the prevention and treatment of ischemic cerebrovascular disease due to its low complication and definite curative effect. ?
