During 2 years and 8 months (1980.9.-1983.4), 100 patients of arteriosclerosis were admitted to our hospital. Of these patients, 43 who had clinical symptoms of TIA, RIND, or bruits on the neck or supraclavicular fossa, were reviewed. Ages ranged from 46 to 81 years (mean: 66.3). Male to female ratio was 1.9:1. Of the 43 patients, 33 were submitted to arteriography of the branches of the aortic arch. Thirty-two but one had arteriosclerotic lesions on the 62 arteries: 32 carotid, 18 vertebral, and 12 subclavian arteries, respectively. Morphologically there were 42 stenoses, 13 occlusions, 7 aneurysmal dilatations, and three other lesions. Seven patients were involved only one artery and 25 were involved more than two arteries. Eight patients were involved other regions such as lower extremities, too. Of the 43 patients, 12 were operated upon and there were no operative deaths and complications. Three of 31 who were treated conservatively, died of malignancies and heart failure. Although operative indications for TIA or RIND have been defined, those for asymptomatic lesions have not been established. Once stroke occurred, however, it would become difficult to recover from it. It is hoped that operative indications for asymptomatic lesions are established as soon as possible.
在2年8个月期间（1980年9月至1983年4月），我院收治了100例动脉硬化患者。其中，对43例有短暂性脑缺血发作（TIA）、可逆性缺血性神经功能缺损（RIND）临床症状，或颈部或锁骨上窝有血管杂音的患者进行了回顾性研究。年龄范围为46至81岁（平均66.3岁）。男女比例为1.9:1。43例患者中，33例行主动脉弓分支动脉造影。在62条动脉中，除1例患者外，其余32例均有动脉硬化病变，分别为32条颈动脉、18条椎动脉和12条锁骨下动脉。形态学上有42处狭窄、13处闭塞、7处动脉瘤样扩张和其他3处病变。7例患者仅累及1条动脉，25例累及2条以上动脉。8例患者还累及下肢等其他部位。43例患者中，12例接受了手术治疗，无手术死亡及并发症。31例保守治疗的患者中，3例死于恶性肿瘤和心力衰竭。虽然TIA或RIND的手术指征已明确，但无症状病变的手术指征尚未确立。然而，一旦发生中风，恢复就会变得困难。希望尽快确立无症状病变的手术指征。
