We studied by angiography 80 patients within 6 hours from the onset of symptoms of supratentorial ischaemic stroke. Occlusion of the internal carotid artery in the extracranial segment was found in 19 patients, at the bifurcation in 11 and at the cervical level in 8. While in the chronic phase of stroke, internal carotid artery occlusion in the cervical segment is an uncommon angiographic finding, we found a high frequency of occlusion at this level (8 out of 19) in our patients. Cervical segment occlusion may be due to a dissecting aneurysm or to an intracranial carotid artery occlusion (embolic or atherothrombotic) with subsequent migration of the clot down to this level. A direct embolic occlusion may be postulated as well.
我们对80例幕上缺血性卒中症状发作6小时内的患者进行了血管造影研究。19例患者发现颅外段颈内动脉闭塞，11例在分叉处闭塞，8例在颈部水平闭塞。虽然在卒中慢性期，颈部段颈内动脉闭塞是一种不常见的血管造影表现，但我们发现我们的患者中该水平闭塞的频率很高（19例中有8例）。颈部段闭塞可能是由于夹层动脉瘤或颅内颈内动脉闭塞（栓塞性或动脉粥样硬化血栓形成性），随后血栓向下迁移至该水平。也可以假定为直接栓塞性闭塞。
