对42侧成年人上肢臂外侧皮瓣的动脉来源、皮动脉在皮及皮下组织内的吻合情况及神经分布等进行了观察和测量。1.臂外侧皮瓣的动脉主要来自肱深动脉及桡侧副动脉皮支、肱外侧皮动脉和旋肱后动脉的皮支。皮瓣移植时主要以肱深动脉或桡侧副动脉作为血管蒂。2.分布于臂外侧皮瓣的皮动脉在皮及皮下组织内吻合成微血管网。而由臂内侧、前臀上部来的皮动脉也参与这个动脉网的形成。3.臂外侧皮瓣的静脉包括浅、深两组:浅组是头静脉,外径较粗;深组是肱深静脉或桡侧副静脉,多数有两条与同名动脉伴行。皮瓣移植时,浅、深组静脉可依据受区的条件和需要分别或同时与受区的静脉缝合。4.臂外侧皮神经和前臂后皮神经在不周高度穿出臂外侧肌间隔,分布于臂外侧和前臂背侧皮肤。后者与桡侧副动脉后支的皮支极为密切。5.依据用红墨水灌注肱深动脉所显示的结果,讨论了臂外侧皮瓣的切取范围。臂外侧皮瓣可分为上、中、下臂外侧皮瓣,分别以旋肱后动脉皮支、肱外侧皮动脉和肱深动脉或桡侧副动脉作为血管蒂。
The arterial origin of the flaps of the upper extremity arm of 42 adults and the anastomosis and distribution of nerve in the skin and subcutaneous tissue were observed and measured. 1. The outer arm flap arteries mainly from the deep brachial artery and radial artery branch, the lateral humeral artery and the posterior humeral artery branch. Flap transplantation mainly to the deep brachial artery or radial artery as the pedicle. 2. Distributed in the lateral flap of the skin arteries in the skin and subcutaneous tissue anastomosis into microvascular network. By the inside of the arm, buttocks to the upper part of the arteries also involved in the formation of this artery network. 3. The lateral veins of the arm include the superficial and deep veins. The superficial group is the cephalic vein with thick outer diameter. The deep group is the deep brachial vein or the radial side veins, and most of them have the same artery. Flap transplantation, shallow, deep vein can be based on the conditions and needs of the affected area, respectively, or at the same time with the affected area of the vein suture. 4. The lateral outer arm nerve and the posterior branch of the posterior cutaneous nerve penetrate out of the lateral arm muscle at irregular intervals, which are located outside the arm and the dorsal skin of the forearm. The latter is very close to the dorsal branch of radial artery. 5. Based on the results shown by perfusion of the deep brachial artery with red ink, the excision range of the lateral flap of the arm was discussed. The lateral flap of the arm can be divided into lateral flaps of upper, middle and lower arm. The flaps of the posterior humeral artery, the lateral flanks of the brachialis, the deep brachial artery or the radial sideral arteries are used as the pedicles.
