Ipsilateral subclavian steal in association with aberrant origin of the left vertebral artery from the aortic arch.
نویسندگان
چکیده
Five cases are reported of left subclavian steal syndrome associated with anomalous origin of the left vertebral artery from the aortic arch. In all five instances blood flow at the origin of the left vertebral artery was in an antegrade direction contrary to that usually reported in this condition. The distal subclavian artery was supplied via an extensive collateral network of vessels connecting the vertebral artery to the thyrocervical trunk.

A Case Report of Variant Origin of Left Vertebral Artery from Aortic Arch and its Embryological Explanation
Vertebral artery is the first branch of subclavian artery. It merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. Variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. It originated from aortic arch and was longer as ...
متن کاملSubclavian steal syndrome from the ipsilateral vertebral artery.
We present two cases of subclavian steal syndrome from the ipsilateral vertebral artery (VA) to the subclavian artery (SCA), one with the left VA originating from the aortic arch and the other with the left VA originating very close to the origin of the SCA, proximal to the occluded segment. In both cases, angiographic demonstration of these anatomic variations and successful endovascular treat...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...

Kommerell's diverticulum (KD) is defined as a bulbous dilatation of the origin of an aberrant subclavian artery due to a remnant of the left fourth aortic arch. We report the case of an asymptomatic woman in whom progressive thrombosis of the KD extending to the prevertebral tract of an aberrant right subclavian artery was detected at multidetector computed tomography imaging for lung cancer st...
متن کاملOrigin of the right vertebral artery from the left side of the aortic arch proximal to the origin of the left subclavian artery.
The right vertebral artery most commonly originates from the right subclavian artery. There are a variety of anomalous origins of the right vertebral artery described throughout the literature ( 114); however, in most cases the artery arises from a vessel on the right side of the aortic arch. There have only been three reports of the right vertebral artery crossing over from an origin on the le...
