Duplication of the left vertebral artery in a patient with dissection of the right internal carotid artery and Ehlers–Danlos syndrome: case report and review of the literature
نویسندگان
چکیده
Duplication of the left vertebral artery was observed in a 43-year-old Caucasian male with dissection of the right internal carotid artery during multidetector 64-row computer tomography and Doppler ultrasonography B-flow mode. Both duplicated segments arose from the left subclavian artery and united at levels C5-C6 to form a single vessel. The presented case describes precisely the origin and diameter of both vertebral arteries. Additionally, after all procedures associated with diagnosis and treatment of the patient, Ehlers-Danlos syndrome type IV was diagnosed. The lumen of the duplicated vertebral artery was smaller than normal; it can be concluded that this variant has clinical implications and should be taken into consideration when vertebral arteries need catheterization.

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

Background: The branches of right and left subclavian arteries are important in conducting of blood to spinal cord, posterior cranial fossa, base of the neck, thyroid gland, wall of the thorax and abdomen. The routine use of internal thoracic artery as a conduit in coronary artery bypass grafting surgery requires appreciation of the anatomical variations of these vessels. So far, there is not a...
متن کامل[Carotid dissection associated with Ehlers-Danlos syndrome. Report of one case].
In the vascular type of Ehlers-Danlos syndrome there is a defect in the synthesis of collagen type III, important constituent of the blood vessel wall, which may cause arterial rupture and dissection. We report a 15-year-old girl with a history of Ehlers-Danlos syndrome, who suffered an ischemic stroke secondary to dissection of the right internal carotid artery. She was managed conservatively ...
متن کاملCarotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
