颈动脉窦和虹吸部纵列的动脉硬化损害可增加颈动脉内膜切除术的危险;当虹吸部损害使其严重狭窄时,小血管搭桥可能是有益的处理方法。但作者对两例患严重虹吸部狭窄和明显的颈动脉窦损害的病人,进行了颈动脉内膜切除术,术后动脉造影显示虹吸部狭窄解除。使两个明显颈动脉窦损害病人同侧颈动脉分布区的TIA周期延长。此病例都在 Carotid sinus and siphon atherosclerosis damage can increase the risk of carotid endarterectomy; siphon damage when severe stenosis, the small vessel bypass may be a beneficial treatment. However, the authors performed carotid endarterectomy on two patients with severe stenosis of the siphon and significant carotid sinus damage, and postoperative arteriography showed stenosis was relieved. Two obvious carotid sinus lesions in patients with ipsilateral carotid distribution of TIA cycle extension. This is the case
