Observations of a series of fifteen surgically treated coiled and kinked internal carotid arteries are reported. The kinked internal carotid artery may be clinically significant and can cause cerebral infarction, even in the absence of atherosclerosis. Each patient must be thoroughly investigated and evaluated individually. One must distinguish simple tortuosity without blood flow obstruction from critical kinking of the internal carotid artery. If a patient with angiographic confirmation is symptomatic and other causes are eliminated, surgical correction should be carefully considered, especially if rotational cerebral ischemia is present. The surgical treatment of choice is resection of the redundant internal carotid artery with reimplantation and thromboendarterectomy of any associated plaque. Kinking of the internal carotid artery may lead to aneurysm formation requiring a difficult surgical resection. Although the evidence for a precise causal relationship between kinking of the internal carotid artery and cerebrovascular symptoms is sometimes difficult to establish, it is our belief that a more aggressive surgical approach may be warranted in this potentially disabling and even fatal condition.
