The external carotid artery is an important collateral pathway for cerebral perfusion when the internal carotid artery is occluded. After internal carotid artery occlusion, there is a definite risk of ipsilateral neurological events. The authors retrospectively examined their experience with endarterectomy of the external carotid artery for symptomatic internal carotid artery occlusion. Results based on the authors' experience and on historical data show external carotid endarterectomy to be a safe procedure. Obliteration of the cul-de-sac appears to be a very important factor in the prevention of reocclusion or recurrence of symptoms after external carotid endarterectomy. Use of the internal carotid artery stump for patching of the endarterectomized external carotid artery is both safe and effective in treating symptomatic internal carotid artery occlusion.
当颈内动脉闭塞时，颈外动脉是脑灌注的重要侧支循环途径。颈内动脉闭塞后，同侧发生神经事件的风险明确。作者回顾性研究了他们对有症状的颈内动脉闭塞行颈外动脉内膜切除术的经验。基于作者经验和历史数据的结果表明，颈外动脉内膜切除术是一种安全的手术。盲端闭塞似乎是预防颈外动脉内膜切除术后再闭塞或症状复发的一个非常重要的因素。使用颈内动脉残端修补颈外动脉内膜切除术后的缺损，在治疗有症状的颈内动脉闭塞方面既安全又有效。
