In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [1] [2] It travels down the right coronary sulcus, towards the crux of the heart.

Dorsal Radial Artery (DRA): DRA originates directly from radial artery (in two-thirds of specimens 13 ) at the level of trapezio-metacarpal joint and runs parallel to the extensor pollicis longus tendon (Figure 7 and 8).

Jun 28, 2020 · The reverse digital artery (RDA) flap described in 1986 by Kojima et al1 is used for one-stage reconstruction of finger pulp defects. Lai et al modified this to include a dorsal sensory nerve branch for reinnervation of the flap. 2

Jun 25, 2024 · Radial artery coronary bypass is a surgical procedure utilizing the radial artery as a conduit for coronary artery bypass grafting (CABG). The radial artery is preferred after the left internal mammary artery, as it is easier to harvest and has better long-term patency rates than saphenous vein grafts (SVGs).

The radial artery (RA) has emerged as the second arterial graft of choice. It has the same patency as the right internal thoracic artery (ITA) when placed to the same vessels under the same conditions, but is much more versatile and easier to use. 4

Dec 11, 2016 · The RDP runs in the posterior interventricular groove. In 60% the sinus node artery arises from the proximal portion of the RCA. The left main coronary artery (LMCA) originated in the left sinus of Valsalva. Its length varies from 5-10mm. Sporadically the LMCA is absent, resulting in separated ostia of RCx and LAD.

The artery of the thumb in palmar side and artery of the index arise from ulnar digital artery (UDA), radial digital artery (RDA) and radialisindicis (RI), respectively (Fig. 2).

Digital artery lacerations usually occur secondary to open puncture wounds to the hand, but these injuries may also result from severely displaced fractures or crush injuries.

Sep 6, 2024 · The right coronary artery (RCA) is one of the two main coronary arteries that supply the heart with oxygenated blood. The right coronary artery arises from its ostium in the right sinus of Valsalva, found between the aortic valve annulus and the sinotubular junction.

Superficial palmar branch of radial artery (SUPBRA)–based flaps are a useful option for the reconstruction of volar defects of the digits and palm providing a ‘like for like’ reconstruction with glabrous skin. We and other authors have reported and presented its use as free and pedicled (antegrade and reverse) flaps 1, 2, 3, 4.
