在39头猪上，以大网膜为载体，制作了四种不同类型的二期岛状皮瓣。本研究表明：1.皮肤移植（劈裂或全层），当移植到大网膜，可以转化为一个“岛状皮瓣”，并与微血管吻合，这种皮瓣的自由转移是可行的。2.皮瓣，联合皮瓣，或两者和颌下肌可以用网膜血管化，以获得网膜岛状皮瓣或网膜岛状肌皮瓣，并如前所述转移。3.三种类型的继发性岛状骨皮瓣使用网膜。这些皮瓣中，8个成功地进行了微血管转移。采用各种标准诊断技术，包括99 mTc-焦磷酸四环素标记，微血管造影和组织切片，证明了骨血管和不连续的活力。除了在重建手术中游离活骨移植的许多公认的优点外，这种新型岛状复合皮瓣的其他优点包括其尺寸不受限制，供体畸形最小，易于转移。我们已经证明，网膜可用于血管化皮肤，皮瓣，胫骨，肋骨或髂骨移植，以获得第二个岛状皮瓣。这些皮瓣的临床应用为重建手术提供了一个新的和令人兴奋的视野。
In 39 pigs, four varieties of secondary island flaps were created using omentum as a carrier. This study demonstrates that: 1. Skin grafts (split- or full-thickness), when grafted to omentum, can be transformed into an "island flap," and the free transfer of this flap with microvascular anastomosis is feasible. 2. A skin flap, a combined skin flap, or both and subjacent muscle could be vascularized with omentum to obtain an omental island skin flap or an omental island musculocutaneous flap and transferred as already described. 3. Three varieties of secondary island osteocutaneous flaps were created using the omentum. Of these flaps, eight successfully underwent microvascular transfer. Bone vascularity and incontinuity viability were demonstrated by employing a variety of standard diagnostic techniques, including 99mTc-pyrophosphate tetracycline labeling, microangiography, and histologic sectioning. In addition to the many recognized advantages of a free living bone graft in reconstructive surgery, other benefits of this new kind of island composite flap include its unlimited size, minimal donor deformity, and ease of transfer. We have demonstrated that omentum can be used to vascularize skin, a skin flap, and either tibial, costal, or iliac bone graft to obtain a secondary island flap. The clinical uses of these flaps promise a new and exciting horizon in reconstructive surgery.
