Abstract

OBJECTIVE

To systematically determine the location and number of cutaneous perforators greater than 0. 5 mm in diameter of the lateral branch of the thoracodorsal artery perforator flap for resurfacing shallow defect.

MATERIAL AND METHOD

Sixty dissections of the thoracodorsal arterial system were carried out in 30 preserved cadavers. The location and number of cutaneous perforators greater than 0.5 mm in diameter of the lateral branch of the thoracodorsal artery perforator flap were studied and measured.

RESULTS

Seventy-six perforators were found in 60 flaps (1.3 perforators per flap). The first perforator was exited in all dissections. It emerged from the latissimus dorsi muscle 9.8 cm below the dome of the axilla. In 21.67% of the cases, the second perforator of the thoracodorsal artery arose 3.4 cm distal to the origin of the first perforator The third perforator was found in 5% of dissections, and originated 3.0 cm away from the origin of the second perforator In addition, most perforators penetrated the muscle within 7.0-14. 0 cm below the dome of the axilla.

CONCLUSION

The center of the flap designed should be placed between 7 to 14 cm from the dome of the axilla.

摘要

目的

系统地确定用于修复浅表缺损的胸背动脉穿支皮瓣外侧支直径大于0.5mm的皮穿支的位置和数量。

材料与方法

在30具防腐尸体上对胸背动脉系统进行60次解剖。研究并测量胸背动脉穿支皮瓣外侧支直径大于0.5mm的皮穿支的位置和数量。

结果

在60个皮瓣中发现76个穿支（每个皮瓣1.3个穿支）。所有解剖中均发现第一穿支。它从腋窝顶下方9.8cm处的背阔肌穿出。在21.67%的病例中，胸背动脉的第二穿支在第一穿支起点远侧3.4cm处发出。在5%的解剖中发现第三穿支，其起源于距第二穿支起点3.0cm处。此外，大多数穿支在腋窝顶下方7.0 - 14.0cm范围内穿透肌肉。
