目的:探讨症状性颈内动脉(ICA)闭塞的临床表现和短期预后。方法:从住院的缺血性脑血管病患者检查中发现21例ICA闭塞患者,分析他们的临床和影像学表现,并进行短期随访。结果:症状性ICA闭塞占住院缺血性脑血管病患者的2.6%,影像学检查发现皮层下、分水岭性、皮层和大面积脑梗死分别占43%、23.8%、14.0%、9.5%。结论:症状性ICA闭塞以皮层下和分水岭性脑梗死多见,闭塞后仍有较高的卒中发生率。
Objective: To investigate the clinical manifestations and short-term prognosis of symptomatic internal carotid artery (ICA) occlusion. METHODS: Twenty-one patients with ICA occlusion were examined in hospitalized patients with ischemic cerebrovascular disease. Their clinical and radiographic findings were analyzed and short-term follow-up was performed. Results: Symptomatic ICA occlusion accounted for 2.6% of hospitalized patients with ischemic cerebrovascular disease. Imaging examination revealed 43%, 23.8%, 14.0% and 9.5% of subcortical, watershed, cortical and massive cerebral infarction respectively. Conclusions: Symptomatic occlusion of ICA is more common in subcortical and watershed cerebral infarctions, with a higher incidence of stroke after occlusion.
