The purpose of this study was to determine if the rectus abdominis muscle in the dog model could be used as a transposition flap based on its proximal blood supply following ligation of the internal mammary artery. In 11 dogs, the left internal mammary artery and vein were ligated at the fifth intercostal space. Both the left and right rectus abdominis muscles were elevated from their respective beds, dividing the inferior epigastric and intercostal vascular pedicles. Each muscle was then wrapped in a thin silicone sheet and replaced. One week later the dogs were returned to surgery and the muscles inspected. The right rectus abdominis muscle was completely viable in all the dogs. In 10 of the 11 dogs, the left rectus abdominis muscle was completely viable. We conclude that a superiorly based rectus abdominis muscle in the dog can maintain its viability following ligation of its proximal blood supply at the fifth intercostal space.
本研究的目的是确定在狗模型中，在胸廓内动脉结扎后，腹直肌能否基于其近端血供用作转位皮瓣。在11只狗中，在第五肋间空间结扎左胸廓内动脉和静脉。将左右腹直肌从其各自的床中掀起，切断腹壁下血管蒂和肋间血管蒂。然后将每块肌肉包裹在薄硅胶片中并放回原处。一周后，让狗再次接受手术并检查肌肉。所有狗的右腹直肌均完全存活。11只狗中的10只，左腹直肌完全存活。我们得出结论，在狗中，以第五肋间空间近端血供为蒂的腹直肌在其近端血供结扎后仍能维持其存活能力。
