摘要

Objective To observe the number of dorsal perforating branches of the anterior interosseous artery, the diameter of its origin canal, its extent of supply, and its anastomosis with branches of the posterior interosseous artery. Methods Thirteen fresh adult forearm specimens were thawed and dissected after perfusion of red latex for artery visualization. The forearm skin and flexor muscles were removed from ten specimens to expose the anterior interosseous artery and its dorsal perforating branch...更多

Objective To observe the number of dorsal perforating branches of the anterior interosseous artery, the diameter of its origin canal, its extent of supply, and its anastomosis with branches of the posterior interosseous artery. Methods Thirteen fresh adult forearm specimens were thawed and dissected after perfusion of red latex for artery visualization. The forearm skin and flexor muscles were removed from ten specimens to expose the anterior interosseous artery and its dorsal perforating branch. The number and diameter of the dorsal perforating branches of the anterior interosseous artery at its origin were measured and recorded. By dissecting deeper along the gap between the radial wrist flexor and finger extensor muscles, the number of dorsal branches of the anterior interosseous artery and their supply to the dorsal extensor muscles of the forearm were observed. Additionally, thirteen forearm specimens were dissected to observe the anastomosis between the dorsal perforating branches of the anterior interosseous artery and the branches of the posterior interosseous artery in the gaps between the dorsal superficial extensor muscles, deep extensor muscles, and between the deep and superficial extensor muscles. Results The total number of dorsal perforating branches of the anterior interosseous artery was 94 in the ten specimens, with a range of 7 to 12 branches per side. The diameter of the canal at the beginning ranged from 0. 21 to 1. 56 mm （mean of 0. 70±0. 34 mm . The dorsal perforating branches of the anterior interosseous artery primarily supplied the dorsal deep extensor muscles of the forearm and also provided branches to the extensors of the digits in the distal one-third of the forearm. Among the thirteen specimens, there were seven instances of single anastomosis, five instances of double anastomosis, and one case of non-anastomosis between the dorsal perforating branch of the anterior interosseous artery and the branch of the posterior interosseous artery. Conclusions The dorsal branches of the anterior interosseous artery, which were more numerous and had a larger diameter at the beginning, primarily supplied the dorsal deep extensor muscles, extensor digitorum superficialis, and extensor digitorum profundus of the forearm. Anastomosis between the dorsal branches of the anterior interosseous artery and branches of the posterior interosseous artery could occur as single or double anastomoses, or may be absent.收起
