ABSTRACT

The study of variations in the origin of radial artery taken for study due to its great importance in clinical practice and in Surgical practice. The anatomical knowledge for the variations of radial artery is essential for clinicians and Surgeons, as the radial artery is the choice of artery in recent advanced procedures for vascular Surgeries & diagnostic purpose. The radial artery is important for radiologists during Surgical invasive and non-invasive manipulative procedures. Caronary artery bypass grafting has gained wide spread of importance in treating Coronary artery diseases, the radial artery is the artery must widely used as harvesting material in Caronary artery bypass grafts (CABG). Radial artery is the artery of choice for dialysis in Chronic renal failure (CRF) by making an autogenous fistula because of peak flow rate. The radial artery is also used in reconstructive microvascular Surgeries. Radial pulse is of clinical importance, presence of radial pulse indicate systolic blood pressure of more than 70mm of Hg. Radial artery puncture is performed to obtain arterial blood sampling for gas analysis. Materials and Method: The present study conducted in 100 upper limbs of 50 cadavers in Guntur Medical college, Guntur during the dissections of 1st year MBBS students for a period of 5 years. Results: Length of arteries were measured from the point of bifurcation of brachial artery into radial and ulnar arteries. (1) High origin was observed in 5 cadavers out of 50 Cadavers. 3 Specimens shown – high origin of radial artery in the middle of arm. (2) One specimen the radial artery originated from axillary artery and the brachial artery continued as ulnar artery. (3) One case the radial artery arised from the brachial artery at the upper part of the arm. Conclusion: Incidence of variations 10% (5 out of 50 cadarers). In the middle of the arm = 6%, From the axillary artery 2%, In the upper arm 2% variant origin of radial artery noted.
