		In its course downward, it lies upon the tendon of the Biceps brachii, the Supinator, the Pronator teres, the radial origin of the Flexor digitorum sublimis, the Flexor pollicis longus, the Pronator quadratus, and the lower end of the radius.
		The superficial branch of the radial nerve is close to the lateral side of the artery in the middle third of its course; and some filaments of the lateral antibrachial cutaneous nerve run along the lower part of the artery as it winds around the wrist.
		The volar carpal branch (ramus carpeus volaris; anterior radial carpal artery) is a small vessel which arises near the lower border of the Pronator quadratus, and, running across the front of the carpus, anastomoses with the volar carpal branch of the ulnar artery.

	Radial artery - Wikipedia, the free encyclopedia
		In human anatomy, the radial artery is the main blood vessel, with oxygenated blood, of the lateral aspect of the forearm.
		The radial artery arises from the bifurcation of the brachial artery in the cubital fossa.
		The artery's pulse is palpable in the anatomical snuff box and on the anterior aspect of the arm over the carpal bones (where it is commonly used to assess the heart rate and cardiac rhythm).

		Commonly, the radial artery is the vessel of choice; it is readily accessible, and the hand usually has extensive collateral circulation.
		The radial artery arises at the bifurcation of the brachial artery, most commonly just distal to the antecubital fossa, and then traverses distally along the radial side of the volar forearm under the brachioradial muscle and the radial flexor muscle of the wrist (flexor carpi radialis).
		The radial artery contributes to the principal artery of the thumb and the radial artery of the index finger.

	Radial artery appears to be a safe alternative to femoral artery for catheter procedures
		Instead of threading catheters from the femoral artery in the groin, cardiologists can safely use the radial artery in the arm to gain access to coronary arteries for angioplasty, stent placement, and other procedures, according to a new meta-analysis in the July 21, 2004 issue of the Journal of the American College of Cardiology.
		It is useful for cardiologists to learn the radial approach in addition to the femoral approach, so they have the opportunity to choose the right one in every patient, and in order to predict possible complications and avoid them," said Pierfrancesco Agostoni, MD at the University of Verona in Italy.
		Threading a catheter through arteries from the arm to the heart is considered more challenging because there are more turns than in the relatively straight route from the groin.

	Radial Artery Provides Reliable Conduit Option
		Use of the radial artery as a conduit during CABG was examined, then abandoned, during the 1970s, as the radial artery was found to be subject to spasm as well as being associated with complications resulting in ischemia of the hand.
		Anderson and his surgical team began using the radial artery in 1996, performing 98 harvests in 72 patients between November 1996 and July 1998.
		Especially useful for patients who have limited conduit options because of previous bypass surgery or whose saphenous veins are undesirable, the radial artery provides physicians with a reliable conduit choice, as the radial artery is more uniform in size and characteristic.

		The radial approach has virtually eliminated these complications. In addition, some angioplasty procedures may require powerful blood thinners (glycoprotein IIb/IIIa inhibitors) which are safer to use when the radial approach is chosen.
		Patients done via the radial artery are able to sit up immediately and potentially discharged from the hospital within 1-2 hours if no angioplasty is necessary.
		All of the cardiologists in the LIJ Cath Lab are committed to the radial approach for coronary angiography and interventions. When cardiac catheterization or angioplasty is required, it makes sense to choose LIJ.

	Southcoast Health System & Southcoast Hospitals Group
		— Southcoast Hospitals are among the first hospitals in New England to use a new less-invasive procedure to harvest the radial artery for use during cardiac bypass surgery, reducing pain and scar size and lowering infection risk in heart surgery patients.
		Cardiac bypass surgery is a procedure called coronary artery bypass grafting (CABG) that is used to extract a healthy vessel from another part of the body.
		The procedure typically includes surgically removing, or "harvesting," a vein or artery from the leg or arm or chest and is performed by the physician assistant (PA) at the same time as the surgeon is preparing the heart for bypass.

	Use of Radial Artery in Coronary Artery Bypass Grafting: Currents: UI Health Care
		The goal of coronary artery bypass grafting (CABG) is to eliminate angina and improve myocardial perfusion.
		The right gastroepiploic, inferior epigastric, splenic, subscapular, and radial artery (RA) are also successfully grafted as arterial conduits, thus increasing the range of choices available to the surgeon.
		As a conduit in CABG, RA potential benefits are: a) the high proportion of total arterial revascularization of the heart achievable; b) RA’s diameter is greater than that of the IMA; c) RA is rarely affected by atherosclerosis; and d) RA is normally subjected to systemic blood pressure.
