在手术显微镜下,解剖观察了50侧用红色乳胶灌注动脉的成人上肢标本。共有12个动脉源参加腕部的动脉网。腕部动脉网在背侧有三个层次,掌侧有两个层次。位于腕关节囊掌侧和背侧的动脉网最为完整,是腕部动脉吻合交通的主要动脉网。腕背侧动脉网,主要由桡动脉腕背支、骨间前动脉背侧支及上穿动脉上支吻合形成。腕掌侧动脉网,主要由桡动脉腕掌支、骨间前动脉掌侧支和尺动脉腕背支参加。骨间前动脉在腕部与桡、尺两动脉均有广泛吻合,但从吻合管径和吻合数量看,则具有桡侧优势。前臂动脉干与手部动脉干之间,通过腕掌侧和背侧动脉网建立的侧副吻合,则显示背侧优势。腕部的动脉网,呈现多来源、多吻合、多层次的构筑特点,与多关节、多活动、多层次的腕部结构和功能相适应。 本文从形态学上讨论了,腕部桡、尺动脉两支或任何一支在急性或慢性阻断时,腕部动脉网代偿动脉干供应手部血液的可能性。
Under the surgical microscope, adult upper extremity specimens of 50 arteries infused with red latex were dissected. A total of 12 arterial sources participate in the arterial network of the wrist. Wrist arteries in the dorsal three levels, palm has two levels. The arteries located at the palmar and dorsal aspect of the wrist joint capsule are the most intact and are the main arterial network for carotid artery anastomosis traffic. Wrist dorsal artery network, mainly by the radial artery dorsal branch, anterior interosseous artery dorsal branch and the upper branch of the arteries formed anastomosis. Wrist palm artery network, mainly by the radial artery wrist branch, anterior interosseous artery and dorsal ulnar artery ulnar artery branch to participate. Anterior interosseous artery in the wrist and radial, ulnar two arteries are widely consistent, but from the number of anastomosis diameter and anastomosis, then has a radial advantage. Dorsal superiority was demonstrated between the anterior and posterior arteries, the side-to-side anastomosis established by the carpal and dorsal arteries. Wrist artery network, showing multiple sources, more consistent, multi-level construction features, and multi-joint, multi-activity, multi-level wrist structure and function to adapt. This article morphologically discusses the possibility of compensating for the supply of blood to the hand by two or more of the wrist radial and ulnar arteries, either in acute or chronic obstruction.
