犬肋骨膜肌瓣食管成型术的应用解剖及实验研究

目的：为带血供的骨膜肋间肌瓣食管成型术提供解剖学和形态学基础。方法：取１０条犬的肋骨膜肌瓣标本，将其上的第７肋间血管灌注后观察分布情况。手术先切除部分第７肋骨，然后将保留的骨膜和上下肋间肌修整成一个带血管蒂的骨膜肌瓣。瓣上８．５～１２．５ｃｍ，宽４．５ｃｍ，以此肌瓣修复１／２直径４ｃｍ长的食管缺损。结果：带蒂的骨膜肌瓣由肋间动脉的两条主干分支供血，具有良好的血运。尽管处死犬检查手术修复部位轻度狭窄

Applied anatomy and experimental study of esophagoplasty with osteoperio-intercostal muscle flap in dog

To provide anatomical and morphologic basis for the esophagoplasty with vascularized osteoperio- intercostal muscle flap in dogs. Methods: The seventh intercostal vessels of the pedicled flap was fixed and observed on 10 dog specimens. After a segment of the seventh rib on the right chest was removed, the left osteoperiost with connective muscles was cut into a pedicled flap, 8.5 - 12.5 cm long and 4.5 cm wide, which was used to repair the esophageal defect with 1/2 diameter and 4 cm long. Results: The pedicled flaps were supplied with rich vessels from two main branches of the seventh intercostal artery. The experimental animals were as same as the nounal animals in diet and action although a little stricture was formed in the repaired region after operation. Conclusion: Ostoperio-intercostal muscle flap is a feasible donor for esophagoplasty in thorn.
