2023年10月30日 · The deep palmar arch is an anastomotic vessel found in the deep compartment of the hand. It is mainly formed by the radial artery with a contribution of the ulnar artery via its deep palmar branch.

The deep palmar arch (deep volar arch[1]) is an arterial network found in the palm. It is usually primarily formed from the terminal part of the radial artery. The ulnar artery also contributes through an anastomosis. This is in contrast to the superficial palmar arch, which is formed predominantly by the ulnar artery.

2024年4月22日 · The deep palmar arch is the terminal branch of the radial artery, usually forming an anastomosis with the ulnar artery 1. The radial artery enters the palm in between the oblique and transverse heads of adductor pollicis muscle, coursing across the palm approximately 1 cm proximal to the superficial palmar arch 1.

2025年1月24日 · The deep palmar arch is a major arterial structure in the hand, formed primarily by the radial artery with contributions from the deep branch of the ulnar artery. It plays a key role in providing blood supply to the deep structures of the palm, including the muscles, tendons, and bones of the hand.

The deep palmar arch is the terminal branch of the radial artery. The arch is completed by anastomosis with the deep palmar branch of the ulnar artery. The deep palmar arch begins at the lateral aspect of the base of the second metacarpal, near the first dorsal interosseous muscle.

2024年4月22日 · Superficial component superficial palmar arch the superficial branch of the ulnar artery distal to the flexor retinaculum superficial to the long flexor tendons of the digits and deep to the palmar aponeurosis in two-thirds of cases, the palmar arch is incomplete and forms a hockey-stick shape arch lies across the center of the palm at …

2023年8月8日 · As the arteries carry blood across the wrist and reach the palm, they anastomose to form two arches called the superficial volar arch and the deep volar arch. These arches, along with their branches, form an abundant network of blood vessels that is responsible for providing oxygenated blood to all musculoskeletal components of the hand and ...

2023年11月2日 · Deep palmar arch – The deep palmar arterial arch is formed primarily by the radial artery. It lies across the bases of the metacarpals. The deep palmar arterial arch arises from the princeps pollicis, radialis indicis, and three palmar metacarpal arteries. It terminates by anastomosing with the superficial palmar arterial arch.

The deep palmar arch is formed by anastomosis of the continuation of the radial artery with the deep palmar branch of the ulnar artery. With recent advances in microsurgical techniques for vascular repair, the knowledge of variations in the arteries of the hand, as well as the caliber of these arteries, has become more important for surgeons.

2018年10月29日 · According to the usual textbook description, the palmar metacarpal arteries from the deep arch unite with the common palmar digital arteries from the superficial palmar arch. Thus, both arches supply the fingers.
