We reviewed bilateral carotid angiograms of 74 patients with strictly unilateral carotid ischemic symptoms to evaluate asymptomatic atherosclerosis. Symptomatic arteries showed more stenosis than the asymptomatic counterparts, especially in patients with multiple TIAs, amaurosis fugax, or TIAs lasting less than 60 minutes. However, the frequency or degree of ulceration did not differ, and the proportion of stenotic lesions that appeared ulcerated was nearly equal on the symptomatic and asymptomatic sides.
我们回顾了74例有严格单侧颈动脉缺血症状患者的双侧颈动脉血管造影片，以评估无症状性动脉粥样硬化。有症状的动脉比无症状的动脉显示出更多的狭窄，尤其是在患有多次短暂性脑缺血发作（TIA）、一过性黑矇或持续时间少于60分钟的TIA患者中。然而，溃疡形成的频率或程度并无差异，且有溃疡形成的狭窄病变比例在有症状侧和无症状侧几乎相等。
