The radial artery is also used to evaluate the collateral circulation of blood through the hands; applying pressure through palpating the palmar arches results in paleness over the area being compressed; adequate collateral circulation can be ascertained by how quickly normal colour returns after the pressure is removed.
The radialis indicis artery (radial artery of index finger) is a branch of the radial artery that provides blood to the index finger.. It arises close to the princeps pollicis artery, and descends between the first dorsal interosseous muscle and the transverse head of the adductor pollicis, and runs along the lateral side of the index finger to its extremity, where it anastomoses with the ...
The radial artery is occasionally used as a conduit for bypass surgery, and its patency lasts longer in comparison to the saphenous veins. Prior to heart bypass surgery, the test is performed to assess the suitability of the radial artery to be used as a conduit. A result of less than 3 seconds is considered as good and suitable.
The lateral border (radial side) is a pair of parallel and intimate tendons, of the extensor pollicis brevis and the abductor pollicis longus. [1] (Accordingly, the anatomical snuffbox is most visible, having a more pronounced concavity, during thumb extension.) The proximal border is formed by the styloid process of the radius
The ulnar artery also contributes through an anastomosis. [1] The deep palmar arch lies upon the bases of the metacarpal bones and on the interossei of the hand. It is deep to the oblique head of the adductor pollicis muscle, the flexor tendons of the fingers, [1] and the lumbricals of the hand.
First, a quick science lesson on cold hands: “The body regulates the temperature of the hand mainly by controlling blood flow through the radial and the ulnar arteries,” Dr. Abayomi Ogunwale ...
To prevent hand ischemia, there is a "squirt test" that involves squirting blood from the radial artery, which is used in intraoperative assessment of collateral arm blood flow before radial artery harvest. [3] This is more commonly called "Allen's test" by microvascular surgeons, and is used before harvesting radial artery based free tissue ...
The first dorsal interosseous muscle is larger than the others. Between its two heads, the radial artery passes from the back of the hand into the palm. Between the heads of dorsal interossei two, three, and four, a perforating branch from the deep palmar arch is transmitted. [2]
