Abstract

The present study included cadaveric dissection with clinical study and histological study. The results of the study are based on the routine dissection methods, radiological methods including doppler study. The branching pattern and the variation of the radial artery in the present study has contributed to our knowledge regarding the relationship, course and the variation of the branching pattern which is of considerable practical importance in the conduct of reparative surgery in the forearm and hand. The arterial variations of the upper limb have been implicated in different clinical situations. In the present study variations regarding the level of origin and the branches of the radial artery, their contribution to superficial palmar arch and deep palmar arch are encountered. Careful scrutiny of the anti cubital area should be made preceeding simple veni puncture, there is a possibility of accidental intra arterial injections may lead to gangrene of fingers, hand and forearms (fig – 60, 61). The superficial position of the arteries make them vulnerable to trauma and also make them more accessible to cannulation if needed such as for arterio venous fistula in chronic renal failure, diabetes mellitus for dialysis purpose. The superficial radial artery has been encountered during elevation of the radial forearm flap. The existence of the superficial radial artery implies the absence of the normal radial pulse at the wrist level. The absence of the ulnar artery was responsible for hand ischaemia after radial artery grafting for coronary bypass. Traditionally blocks in the heart are treated through angioplasty performed through the artery of the groin which sometimes result in complications like prolonged bed rest, bleeding, blood clots, damaged artery and so on. Now in recent practices, cardio thoracic surgeons have introduced “Radial Artery Access” by which a pinhole access through the wrist as a day care procedure. Through a tiny puncture catheters and stents are guided through the artery to the blocks in the heart. No need for incision, stitches, big scars or long recovery. So the present study of “Radial artery and its branching pattern and variations” will be more useful to the clinicians especially vascular surgeons and plastic surgeons.
