A Case Report of Variant Origin of Left Vertebral Artery from Aortic Arch and its Embryological Explanation
Authors
Abstract:
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 compared with the right vertebral artery. Its further course was as usual. Awareness of such variations is important in supra-aortic vascular surgery and is clinically significant during diagnostic procedures like angiographi.

The duplicated origin of vertebral artery (VA) is a very rare condition. It could be easily misdiagnosed as an arterial dissection on selective catheter angiography, especially in a patient with acute cerebellar infarction of unknown etiology. We report a patient with an acute cerebellar infarction and duplicated origin of the left VA, which was found during the selective catheter angiography.

Purpose: Several variations of aortic arch have been reported yet. In present study another variation of aortic arch was reported. Right subclavian artery arises from posterior surface of the distal end of the aortic arch. Case Report: we present a variation of an aorticarch in which right subclavian artery arisesfrom posterior surface of the distal end of the aortic arch and passing behind eso...

In anatomy, normality embraces a range of morphologies. It includes those that are more common and others called variations which are less frequent but not considered abnormal [1]. Arterial derangements within the thorax are common, complex and can assume many diverse forms. These derangements in origin and course of main vessels occurring either individually or in combination with other cardio...

The left internal mammary artery is commonly used during coronary artery bypass grafting to provide direct revascularization for arteries, typically left anterior descending artery, with significant coronary atherosclerosis. In the world medical literature, we identified only 3 cases of well-documented anomalous origin of the left internal mammary artery from the aortic arch identified followin...
