A secondary TRAM flap was prefabricated in a rat model using the rectus muscle. The right rectus muscle was elevated as an inferiorly pedicled muscle flap in one experimental group (n = 6) and as a superiorly pedicled muscle flap in a second group (n = 5) and then sandwiched between a silicone sheet and the abdominal skin. Two weeks later, the abdominal skin and attached rectus muscle were elevated over the silicone sheet as a secondary TRAM flap. The surviving skin paddle areas of these prefabricated TRAM flaps were compared with superiorly (n = 7) and inferiorly (n = 8) pedicled TRAM flaps in a control group. One-way analysis of variance did not show significant differences between groups (p = 0.07). TRAM flap prefabrication in the rat model yields a skin paddle survival area comparable to that of a conventional TRAM flap, and it is possible to perform this procedure without using the anterior rectus sheath.
在大鼠模型中使用腹直肌预制了一个二期横行腹直肌肌皮瓣（TRAM瓣）。在一个实验组（n = 6）中，将右侧腹直肌作为下蒂肌瓣掀起，在另一组（n = 5）中作为上蒂肌瓣掀起，然后夹在硅胶片和腹部皮肤之间。两周后，将腹部皮肤及附着的腹直肌作为二期TRAM瓣在硅胶片上方掀起。将这些预制TRAM瓣的存活皮瓣面积与对照组中上蒂（n = 7）和下蒂（n = 8）TRAM瓣进行比较。单因素方差分析未显示组间有显著差异（p = 0.07）。在大鼠模型中预制TRAM瓣所获得的皮瓣存活面积与传统TRAM瓣相当，并且不使用腹直肌前鞘也可以进行该手术。
