Obliterative processes of the carotid bifurcation can be a starting point for cerebral and especially retinal microemboli. Early diagnosis is essential in protecting such patients from a definitive insult, or a reduction of sight which can go as far as permanent blindness, whereas the amaurosis fugax being the most common ocular symptom of the internal carotid insufficiency. Due to the fact ca. 65%--75% of the patients with ocular symptoms of a carotid insufficiency show forms of amaurosis fugax or photopical sensations, this symptom complex, especially in combination with temporary contralateral hemiparalysis, has to be evaluated as a classical symptom of carotid stenosis until the contrary can be angiographically proven. Only during the last few years has it become apparent that these microemboli originate from ulcerous or verrucous beds of the carotid bifurcation. The discovery of the above connections was only made possible through the improvements in carotid angiography technique.
颈动脉分叉处的闭塞性病变可能是脑微栓子尤其是视网膜微栓子的起始点。早期诊断对于保护此类患者免受最终的损伤或视力减退至关重要，视力减退甚至可能发展为永久性失明，而一过性黑矇是颈内动脉供血不足最常见的眼部症状。由于约65% - 75%有颈动脉供血不足眼部症状的患者表现为一过性黑矇或光幻觉形式，这种症状复合体，尤其是与暂时性对侧偏瘫相结合时，在血管造影证实相反情况之前，必须被视为颈动脉狭窄的典型症状。直到最近几年才明显发现这些微栓子起源于颈动脉分叉处的溃疡性或疣状病灶。上述关联的发现仅通过颈动脉血管造影技术的改进才成为可能。
