Visualization in angiographic investigations of the common carotid artery of certain collateral circulation routes can sometimes facilitate evaluation of the site of occlusion and its extent. Collateral circulation via the arterial network of the nape of the neck indicates stenosis or occlusion of the subclavian artery. Collateral circulation through the muscular branches of the occipital artery to the vertebral and basal arteries suggests lesions in the vertebral artery. Collateral circulation via the anterior communicating artery suggests stenosis or occlusion of the contralateral internal carotid artery. Visualization in the angiograms of the common carotid artery of numerous channels of collateral circulation indicates presence of disseminated changes in the extracranial brain-supplying arteries.
在颈总动脉血管造影检查中，某些侧支循环途径的显影有时有助于评估闭塞部位及其程度。通过颈部动脉网络的侧支循环提示锁骨下动脉狭窄或闭塞。通过枕动脉的肌支至椎动脉和基底动脉的侧支循环提示椎动脉病变。通过前交通动脉的侧支循环提示对侧颈内动脉狭窄或闭塞。颈总动脉血管造影中众多侧支循环通道的显影提示颅外脑供血动脉存在弥漫性改变。
