一过性大脑半球缺血性发作(HTIA)、黑朦与颈内、外颈动脉系统的溃疡性,闭塞性病损有关。但已往报告对颈动脉有溃疡性病损而无狭窄的重要性尚认识不足。作者对123例患者作颈动脉的血管造影138次(15例进行了双侧造影)。其中HTIA93例;黑朦(有或无HTIA)30例。所有黑朦患者的35次造影中,颈动脉分叉或虹吸部均证实有溃疡性或闭塞性病损存在。其中4例(11%)仅在颈动脉虹吸部有溃疡性病损存生。HTIA患者的103次造影中,94次(91%)在颈动脉分叉处或虹吸部有溃疡性或闭塞性病损存在。这些患者中3例颈动脉虹吸部有孤立的病根存在;1例在颈动脉分叉处病变极小,无名动脉有明显的溃疡性病损。9例(9%)颈动脉造影正常。分叉处有溃疡性病损者为67支(49%);溃疡性病损合并有狭窄者58支(42%);有溃疡性病损而无狭窄者9支(7%)。该处无造影显示的溃疡性病损 A transient hemispheric ischemic attack (HTIA), darkness and the carotid system of the internal and external carotid ulcer, occlusive disease related. However, the importance of reporting ulcerative lesions of the carotid artery without stenosis has been poorly understood. The authors performed carotid angiography 138 times in 123 patients (15 patients underwent bilateral angiography). There were 93 cases of HTIA and 30 cases of hazy (with or without HTIA). In all 35 patients with amaurosis, carotid bifurcation or siphon confirmed the existence of ulcerative or occlusive lesions. Four of them (11%) had ulcerative lesions only in the carotid siphon. Of the 103 radiographs of HTIA patients, 94 (91%) had ulcerative or occlusive lesions at the bifurcation or siphon of the carotid artery. Three of these patients had isolated root lesions in the siphon of the carotid artery; one had minimal disease at the bifurcation of the carotid artery, and the unnamed artery had significant ulcerative lesions. Carotid angiography was normal in 9 cases (9%). 67 (49%) had ulcerative lesions at the bifurcation; 58 (42%) had ulcerative lesions with stenosis; 9 (7%) had ulcerative lesions without stenosis. There is no angiography showed ulcerative lesions
