We have investigated the hemodynamic mechanisms of delay phenomenon of various types of deltopectoral flaps and optimal time for transfer after delay operation using the local clearance method of Xenon-133. Characteristic differences were observed in recovery patterns of the distal blood flow among five types of delay procedure the results obtained are reported. In Group 1 (U-shaped, raised deltopectoral flap), two types of recovery patterns (fast and slow) were obtained. In cases of faster recovery, the optimal transfer time after delay is considered to be almost 10 days. In cases of slow recover in groups I and II (U-shaped, raised deltoid flap), the optimal time for transfer is thought to be 2 to 3 weeks. In group III (deltopectoral flap lined with a split-skin graft) and group IV (tubed, raised deltopectoral flap), a faster recovery pattern was observed than in groups I and II, and the optimum transfer time is considered to be about 7 to 14 days after delay operation. Accordingly, the use of groups III and IV would be highly recommended instead of group I. In group V (bipedicled, raised deltopectoral flap), the time of lateral incision was found to be critical.
我们采用氙-133局部清除法，研究了各类胸三角皮瓣延迟现象的血流动力学机制以及延迟手术后最佳转移时间。观察了五种延迟手术方式中皮瓣远端血流恢复模式的特征差异，并报告了所得结果。在第1组（U形掀起式胸三角皮瓣）中，获得了两种恢复模式（快速和缓慢）。恢复较快的情况下，延迟后的最佳转移时间约为10天。在第I组和第II组（U形掀起式三角肌皮瓣）恢复缓慢的情况下，最佳转移时间被认为是2至3周。在第III组（带断层皮片移植的胸三角皮瓣）和第IV组（管状掀起式胸三角皮瓣）中，观察到比第I组和第II组更快的恢复模式，最佳转移时间被认为是延迟手术后约7至14天。因此，强烈推荐使用第III组和第IV组而非第I组。在第V组（双蒂掀起式胸三角皮瓣）中，发现外侧切口时间至关重要。
