主动脉粥样硬化的CT检查体会

Experience of examination of Aortic Atherosclerosis By CT The First Hospital of Quan Zhou,Fujian

主动脉粥样硬化大多发生在40岁以上,多数病灶先出现在腹主动脉,特别是后壁,然后逐渐向上延伸至胸主动脉。本文对1989年8月至1991年8月期间的551例40岁以上腹部CT检查患者进行分析,认为CT能比常规X线较早发现主动脉钙化。此外,CT增强扫描能发现未钙化的粥样硬化斑块或继发性血栓。表现为主动脉内呈弧形或新月状的低密度影。这对本病的早期诊断和治疗起着重要作用。

The most of patients with aortic atherosclerosis are over 40 years of age. Usually,abdominal aorta is first involved,especially in posterior wall and thoracic aorta fol- low later.In the paper 551 cases over 40 years of age who abdomen were examined by CT were analysed from August 1989 to August 1991.We considered CT can detect calcification of abdominal aorta earlier than x—ray.Besides,entranced CT can discover atherosclerotic plaques without calcifcation or secondary thrombi.Arced or crescent hypodensity shadow can be seen in aprta.CT plays an important role in early diagnosis and treatment of aortic athe- roclerosis.
