TORTUOUS SUPERFICIAL BRACHIAL ARTERY WITH CHANGE IN ITS COURSEâ€“A RARE PHENOMENON-A CASE REPORT
The major arteries of the upper limb show a wide range of variations. In this article a case of superficial tortuous brachial artery and its abnormal course is reported. During routine dissection of a male cadaver of 65 years old, in the Department of Shareera Rachana in JSS Ayurveda Medical College, the right brachial artery was found to be tortuous and superficial to the median nerve and change in its course has been observed. This artery instead of travelling from medial to lateral with respect to median nerve, it is covering the median nerve in the lower part of the arm. The superficial brachial artery continued in the arm without giving any branche and ended in the cubital fossa dividing into radial and ulnar arteries. It showed a remarkable tortuous course with loops and bends in its lower half. Tortuous peripheral arteries are generally asymptomatic but an abnormal superficial tortuous brachial artery and its branches may be mistaken for basilic vein during cannulation. The great variability of this arterial pattern may be attributed to the failure of regression of some paths of the embryonic arterial trunks. The embryological and clinical significance of this variant are also discussed.
