To determine applicability and size limits of an axial pattern flap based on the lateral caudal arteries in dogs to reconstruct caudodorsal trunk skin defects.
Experimental study.
Ten mature, mixed breed dogs.
The lateral caudal vessels of the tail were incorporated in the flaps of the treatment group (n=5) and were ligated in the control group (n=5). Flaps were rotated and placed into experimentally created caudodorsal skin defects on the trunk. The length and area of tissue that remained viable in each flap were determined.
Mean (+/-SD) survival area (222.8+/-32.9 cm2) and length (25.1+/-4.5 cm) of vascularized flaps were significantly greater (P<.05) compared with control flaps (94.9+/-13.4 cm2 and 14.61+/-4.7 cm). Necrosis occurred in all control flaps, resulting in lower percentage flap area (48.8%) and length (47.1%) survival compared with vascularized flaps (78.1%, 77.5%).
Axial pattern flap based on lateral caudal arteries of the tail was successfully elevated and transferred in a single procedure, with 78% survival for closure of large experimentally created caudodorsal trunk defects in dogs.
Large cutaneous defects of the caudodorsal trunk area in dog could be reconstructed with tail axial pattern flap. Limitations in terms of size and changes in animal appearance have to be considered before flap elevation.
确定基于犬尾外侧尾动脉的轴型皮瓣在重建尾背躯干皮肤缺损中的适用性和尺寸限制。
实验研究。
10只成年杂种犬。
治疗组（n = 5）的皮瓣纳入尾外侧血管，对照组（n = 5）结扎尾外侧血管。将皮瓣旋转并置于躯干上实验性造成的尾背皮肤缺损处。测定每个皮瓣中存活组织的长度和面积。
与对照皮瓣（94.9±13.4 cm²和14.61±4.7 cm）相比，带血管蒂皮瓣的平均（±标准差）存活面积（222.8±32.9 cm²）和长度（25.1±4.5 cm）显著更大（P<0.05）。所有对照皮瓣均发生坏死，与带血管蒂皮瓣（78.1%，77.5%）相比，皮瓣面积存活率（48.8%）和长度存活率（47.1%）更低。
基于尾外侧尾动脉的轴型皮瓣在一次手术中成功掀起并转移，用于闭合犬实验性造成的大型尾背躯干缺损时存活率达78%。
犬尾背躯干区域的大面积皮肤缺损可用尾轴型皮瓣重建。在掀起皮瓣前必须考虑尺寸限制和动物外观变化。
