作者报道了１９例因颈动脉硬化性狭窄病变（狭窄超过７０％）致脑缺血患者，经彩超或磁共振血管造影、数控成影血管造影明确诊断，其中３例成功地作了颈动脉内膜切除术，疏通了颈内动脉；有６例因远端颈内动脉完全性阻塞，不能行手术治疗；其它１０例因年迈合并其它严重疾病、医疗费用困难或对接受手术有顾虑等原因暂未接受手术。作者指出：对脑缺血患者（包括短暂性脑缺血和脑梗塞）应作颈动脉的超声检查或造影检查，如发现局限性的颈动脉严重狭窄（超过７０％），则可行颈动脉内膜切除术，可改善脑部血液供应。作者指出在手术中采用颈丛麻醉下的颈动脉钳夹试验，将使手术可安全进行。
The authors reported 19 cases of cerebral ischemia caused by carotid atherosclerotic stenosis (stenosis more than 70%), diagnosed by color Doppler ultrasound or magnetic resonance angiography, digital angiography confirmed angiography, of which 3 were successfully made in the carotid artery Membrane resection, dredging of the internal carotid artery; 6 cases of complete obstruction of the distal internal carotid artery, can not be surgically treated; the other 10 cases due to age and other serious diseases, medical costs or difficulty in receiving surgery and other reasons No surgery. The authors note that carotid ultrasound or angiography should be performed on patients with cerebral ischemia (including transient ischemic attack and cerebral infarction). In the case of localized severe carotid stenosis (over 70%), the carotid artery Membrane resection can improve blood supply to the brain. The authors point out that carotid artery clamp testing under cervical plexus anesthesia during surgery will make surgery safe.
