A case of radiation-induced bilateral common carotid artery stenosis is reported. This 60 years old housewife was hospitalized in 1982 because of sudden onset of mild left hemiparesis. Twenty-five years ago, she underwent radiation therapy of approximately 5,000 rads to the anterior cervical region because of thyroid cancer. Angiograms in 1982 revealed bilateral common carotid artery stenosis, especially in the right common carotid artery, the legion of which were included within the field of radiation performed in 1952. Right thromboendarterectomy was performed in 1983. At operation, slight periarterial fibrosis with calcified arteriosclerotic change was found, and dissection between the thickened intima and the media was not so difficult. Histological change of resected thromboendarterium was similar to the one observed in the pure arteriosclerotic disease.
报告一例放射性双侧颈总动脉狭窄病例。这位60岁的家庭主妇于1982年因突然出现轻度左侧偏瘫入院。25年前，她因甲状腺癌接受了约5000拉德的颈部前方放射治疗。1982年的血管造影显示双侧颈总动脉狭窄，尤其是右侧颈总动脉，其病变位于1952年放射治疗的区域内。1983年进行了右侧血栓内膜切除术。手术时，发现动脉周围有轻微纤维化并伴有钙化性动脉硬化改变，增厚的内膜与中膜之间的分离并不困难。切除的血栓内膜的组织学变化与单纯动脉硬化疾病中观察到的相似。
