Dolichoarteriopathy of Common Carotid Artery: An Unusual Entity.

Dolichoarterial disease of the carotid arteries refers to elongated arteries with tortuous, coiling, and kinking anatomy. This morphology is usually met in the elderly and not associated with atherosclerotic risk factors. Current practice reserves surgical correction only in symptomatic patients. Significant tortuosity index may be associated with stroke and poses extra difficulties to the endovascular passage of guidewires and catheters for the treatment of extra- and intracranial vascular lesions. This article presents a typical case of bilateral dolichoarteriopathy of the common carotid artery and stresses the need for further categorization of the particular morphology based on modern angiography techniques and three-dimensional reconstruction software.
