title: [Rare disorders of extracranial carotid arteries].
abstract: Abnormalities of the internal carotid arteries (ACI) are rare findings, usually not linked with neurologic symptoms and frequently are diagnosed during routine duplex scanning or angiographic examination. These abnormalities are predominantly elongation of the vessel that leads to kinking, coiling or tortuosity of the artery, and the origin is congenital or acquired related to atherosclerosis. We report on two symptomatic cases related to elongation of AC. The first case was a 56-year-old female that had bilateral coiling. The second patient was a 64-year-old female that suffered from symptomatic double coiling of the left ACI connected with high grade stenosis. In both cases, successful operation was done with resection of the elongated and stenosed ACI segment and reanastomosis of the ACI and common carotid artery. Postoperatively, symptoms were resolved. In symptomatic cases of isolated carotid elongations, surgical treatment is a better option than conservative medical treatment alone, whilst in asymptomatic ACI elongation, conservative medical treatment is advised.
