Radial Artery
UNDER CONSTRUCTION[edit | edit source]
Description[edit | edit source]
The Radial artery is a large blood vessel that provides oxygenated blood to the lateral aspect of the forearm. The radial artery and vein runs distally on the anterior part of the forearm, In less than 1% of the population, the radial artery takes a superfical course in the anatomical snuff box.[1]IT IS RECOMMENDED FOR ARTERIAL pulsation to be taken at the anatomical snuff box as this variation has been mistaken for the cephalic vein.
Path[edit | edit source]
the radial artery forms as a bifurcation of the brachial artery in the antecubital fossa.running distally,serving as a landmark for the division between the anterior band posterior compartments of the forearm.with the posterior compartment beginning just lateral to the artery. thevartery winds laterally around the wrist,passing through the anatomical snuff box and between the bheads of the firstdorsAL INTEROSSEOUS muscle. It passes anteriorly between the heads of the adductor pollicis and becomes the heads of the adductor pollicis, and becomes the deep palmer aRCH, WHICH JOINS WITH The deep branch of the ulnar artery
Divisions[edit | edit source]
the radial artery gives off into the forearm,the wrist and the hand.
at the forearm,the radial artery divided into
- radial recurrent artery, this arises after the artery comes off the brachial artery . it travels superiorly to anastomose with the radial collateral artery at the elbow joint
- palmer carpakl branch of radial artery- A SAMMALLER VESSEL WHICH ARISES Near the lower boarder of the pronantor quadratus
- superfical palmer branch of the radial artery
at the wrist,
- dorsal carpal branch
- first dorsal metacarpal artery
at the hand,
- princess pollicis artery
- radialis indicis
- deeo palmer arch
Supply[edit | edit source]
The radial artery provides blood supply to the elbow joint, lateralforearm muscles, radial nerve, carpal bones and joints,thumb,and lateral side of the index finger.
Clinical Relevance[edit | edit source]
the radial artery is clinically significant as it is a promenite medium to assess the heartrate. most clinicians take the radial pulse between the tendons of the brachioradialis and flexorcarpi radialis as this where the radial artery lies superfically.
in cardiac surgery the radial artery is used for coronary artery bypass grafting.
it is a common site for the insertion of an arterial line.
