The Clinical Significance of Radial Artery Morphology in Artificial Arterial-venous Fistula for Hemodialysis

The radial artery usually arises from brachial artery and begins just below the inferior border of teres major. The present study focuses on the radial artery features which are the internal diameter and external diameter as well as thickness of wall and origin level of radial artery to give extensive data for physicians. Present study comprises a dissection of 68 upper limbs which is 34 cadavers (14 female and 20 male cadavers, 34 rights and 34 left). The age range 37-96 years in which the radial artery was investigated. It usually arises distal to the superior margin of the head of the radius in 82.65%. The angle degree of radial artery with respect of brachial artery ranges from to 8 to 30. The internal and external diameters of the radial artery found to be decreasing gradually from proximal to distal in all cases. The right radial artery is more prominent than left one. The right radial artery is a proper choice to select in artificial arteriovenous fistula due its size. Selecting the right radial artery will increase the success rate of artificial arteriovenous fistula. Knowing the morphological of radial artery is essential for radiologists and and surgeons to avoid the iatrogenic faults. With variable morphology of the radial artery, there is a frequent vascular injury may happen during surgical operation. Therefore, identifying the thickness, diameter and variable origin level of the radial artery is clinically
