Bilateral Abnormal Course Of Brachial Artery Related With The Median Nerve In Arm: A Case Report

ABSTRACT

Many formative variations of median nerve are known but this variant formation and course of median nerve israre. A variant formation of median nerve was noted in the axilla and arm of a male cadaver, in the form offormation of median nerve behind the third part of axillary artery and brachial artery wind around mediannerve. There may be compression of the nerve passing around the artery. This variation may be clinicallyimportant because symptoms of median nerve compression arising from similar variations are often confusedwith more common causes such as radiculopathy and carpal tunnel syndrome.During routine dissection, one of the cadaver showed bilateral abnormal course of brachial artery in the arm. Inthe right arm In the axilla, median nerve present posterior to the artery. In the left arm brachial artery twistingaround the median nerve. At the level of the neck of radius brachial artery dividing into radial and ulnar arteriesin both side of upper limb.
