  • Title: Management of kinked extracranial cerebral arteries.
    Author: Poindexter JM, Patel KR, Clauss RH.
    Journal: J Vasc Surg; 1987 Aug; 6(2):127-33. PubMed ID: 3612961.
    Abstract:
    Kinked extracranial carotid and vertebral arteries are observed in 10% to 16% of cerebral angiograms. The hemodynamic significance of some kinked carotid arteries has been shown by investigators who documented oculoplethysmographic and angiographic differences accompanying flexion, extension, or rotation changes of the neck and head. In the 3-year period ending November 1985, we performed operations on seven patients to correct six kinked internal carotid arteries and one kinked vertebral artery at the C-2 level. The final decision regarding optimal operative technique was determined during operation, after observing the relative lengths of dissected arteries, envisioning the results of the procedures selected. We performed five segmental resections and end-to-end anastomoses (one vertebral, two common carotid, and two internal carotid arteries). Transection of the internal carotid artery with reimplantation into the side of the common carotid artery was performed twice. All patients became asymptomatic up to 4 years, irrespective of head and neck positions. There were no complications or deaths in these patients. This experience suggests that arterial kinks may constitute tenable indications for operative treatment in patients with transient cerebral ischemia who lack typical stenotic or ulcerative plaques to account for their symptoms. Kinked arteries can be corrected safely and effectively by appropriate surgical procedures.
