Abstract

Background: The medial upper arm is a potential donor site for the perforator flaps because of its ideal thickness, pliability, excellent color, and well-hidden donor site scar. Its main vascular supply originates from the cutaneous perforators of the superior ulnar collateral artery and brachial artery. The purpose of this cadaveric study was to localize and describe the characteristics of the distal brachial artery perforator (DBAp), which supplies the distal medial upper arm, thereby providing databases for flap elevation.

Methods: A cross-sectional study was carried out in 24 intact upper limbs from 12 fresh cadavers (6 men, 6 women). The surgical procedure was performed through 3 stages to locate the DBAp and then gather anatomical characteristics.

Results: We always identify at least 1 DBAp in each arm. There were 30 perforators (mean number 1.25 ± 0.53). The average external diameter and length of perforator arteries were 0.95 ± 0.22 mm and 3.52 ± 1.29 cm, respectively. The majority of the points where the perforators pierce the deep fascia were spotted within a circle of 3.45 cm diameter, the center of which was 2.82 cm proximal (y value) and 1.40 cm lateral (x value) to the medial epicondyle. A consistent branch of the medial antebrachial cutaneous nerve (MACN) was found supplying sensory innervation to the DBAp flap.

Conclusion: The DBAp flap is a viable option for reconstructing soft tissue defects in the elbow and regions such as the face, head, and neck.

远端肱动脉穿支：解剖学研究。

背景：上臂内侧因其理想的厚度、柔韧性、良好的颜色和良好的隐蔽性而成为穿支皮瓣潜在的供区。其主要血管供应来源于尺上副动脉和肱动脉的皮穿支。本尸体研究的目的是定位和描述供应上臂远端内侧的远端肱动脉穿支（DBAp）的特征，从而为皮瓣提升提供数据库。方法：对12具新鲜尸体（男6例，女6例）的24条完整上肢进行横断面研究。手术过程分3个阶段进行，以定位DBAp，然后收集解剖学特征。结果：我们总是在每只手臂中至少鉴定出1个DBAp。共30个穿支（平均数目1.25±0.53）。穿支动脉平均外径0.95±0.22 mm，平均长度3.52±1.29 cm。大多数穿支穿入深筋膜的点位于直径3.45 cm的圆圈内，该圆圈的中心位于内侧上髁近端2.82 cm （y值）和外侧1.40 cm （x值）。前臂内侧皮神经（MACN）的一致分支支配着DBAp皮瓣的感觉神经。结论：DBAp皮瓣是修复肘关节及面部、头颈部软组织缺损的一种可行方法。
