Radial and Ulnar Artery Dominance Among Sudanese Population-Colour Doppler Ultrasound Study

Abstract

Background: This study aims to describe the appearance of radial and ulnar arteries diameter by mean values and determine the possible dominance of arterial supply in radial or ulnar arteries. Knowledge of the different diameters of forearm vessels is one of the most essential factors in coronary bypass surgery and radial artery conduit. Methods: The study was conducted on 28 individuals (14 male, 14) females with a mean age of 30, 5 years +/- 5, 5 selected systematically by systematic sample technique. Patient prepared for arterial evaluation using color Doppler Ultrasound after 10 minutes rest on a couch. There was no hazard affecting the patients when using colour Doppler ultrasound. All patients have informed consent for ethical clearance. Results: The results showed that the mean diameter of right and left radial arteries were (2.5 +/-.39) SD was (2.4 +/- 0.41) SD mm, (2.1 +/-.29) SD mm, respectively, and right-left ulnar arteries diameter was (2.4 +/-.41) SD mm, (2.2 +/-.43) mm respectively. The dominant arterial supply was the right radial artery. Conclusions: There was no wide variation in mean diameter between radial and ulnar arteries in both hands because most samples were educated using their right hand rather than left. Subsequently, the dominant arterial supply of the hand was the right radial artery.
