Superficial Brachio Ulnar Artery and other Vascular Variants in Left Upper Limb.

Background: Variations in origin, course and distribution of upper limb arteries are well documented and they have a great clinical significance. But the incidence of certain variations like presence of Superficial Brachioulnar Artery (SBUA) is less and its association with other vascular variations in hand are very few. Material: Human male cadaver of about 65 years age, received for student demonstration dissections provided the material for this study. Results & Observations: SBUA originated from brachial artery (BA) in the left upper limb of a human male cadaver. Other vascular variations noted were division of BA into radial artery (RA) and a common trunk (CT) for common interosseous and ulnar recurrent arteries (URA); and variant pattern in completion of Superficial Palmar arch (SPA). Conclusion: Arterial variations of upper limb have been reported to have clinical implications. A variant vessel like SBUA may be encountered during elevation of forearm flaps, or accidental injections of drugs into artery with mistaken identity for a vein, may land in severe complications. Added to these, knowledge of formation of palmar arterial arches and their branching pattern is important in reconstructive surgeries of hand.

Finger print pattern in different blood groups.

Dermatoglyphics is study of pattern of fine ridges on fingers, palms and soles. The term dermatoglyphics was coined by Cummins. The type of finger print is unique and is based on genetic characters of each individual. They develop between 2nd and 3rd months of intra uterine life and remain unchanged in an individual through out life. Finger prints are regarded as the most reliable tool for personal identification. Due to their immence potential particularly in forensic medicine, the study of finger print pattern was carried out in relation to various ABO blood groups. The study was carried out in the Department of Anatomy, NRI medical college, Chinakakani, Guntur. 506 students of known blood group were selected for the study. The finger prints were collected, studied and analyzed statistically. Thumbs presented high frequency of whorls in A+ves. Index and ring fingers were associated with high frequency of whorls in A-ves and AB+ves.
