High Origin Of Radial Artery: An Anatomical Variation With Its Embryological Basis & Clinical Significance.
Kusum R Gandhi, K. Naga Vidya Lakshmi
BACKGROUND: Radial artery is the smaller terminal branch of Brachial artery. Abnormal variations in the anatomy of radial artery may produce an iatrogenic injury leading to undesired complications. MATERIAL & METHOD: Study was carried out on 18 formalin fixed cadavers i.e. 36 limbs of adult age in the Department of Anatomy. Arm and forearm of both upper limbs were carefully dissected to note the variation in the origin of Radial artery. RESULT: Unilateral Variations of high origin of Radial artery were observed in two cases (5.55%). In first case, radial artery was originated from right brachial artery 13.5 centimetre above the intercondylar line while in second case it was 19 centimetres above the intercondylar line. CONCLUSION: In recent times, there has been an increase in the use of radial artery for various diagnostic & invasive procedures which requires the qualified apprehension of the variant anatomy to avoid iatrogenic injury and perform safe procedures.
