Abdominal plastic surgery is a four-level plastic surgery, with high difficulty coefficient and corresponding risks. Usually, there are risks of abdominal wall skin necrosis, hematoma, seroma and surgical infection in abdominal wall plastic surgery. There are risks, and how to reduce the risks during the operation, especially how to effectively prevent skin flap necrosis, is worth discussing. Next, Director Yu Wenlin will answer your questions.

As we all know, the blood supply of abdominal wall is mainly composed of superficial abdominal wall vessels, superficial circumflex iliac vessels, perforating branches of upper and lower abdominal wall arteries, inferior costal arch arteries, intercostal arteries and perforating branches of lumbar arteries. When peeling off the abdominal wall flap, it is inevitable to cut off the perforating branches under the flap. At this time, the blood supply of the flap mainly depends on the superficial abdominal vessels and the perforating branches from bilateral intercostal arteries, lumbar arteries and other segmental arteries. Therefore, when peeling off the flap, don't peel off too much on the outside of the flap, and try to keep the perforating blood vessels above the flap.

At the same time, in order to avoid damaging the main blood vessels in the abdomen, try to use fine needles. In addition, during the suture process, the tension of the flap should not be too large, otherwise it will affect the blood supply of the flap, and the hip flexion position should be used as much as possible after the operation to reduce the tension of the abdominal wall.

Besides skin flap necrosis, hematoma and seroma can not be ignored. Want to avoid postoperative hematoma and serum swelling as much as possible, director Yu Wenlin said:

Once the hematoma appears, it should be removed again, otherwise it may cause infection and skin flap necrosis. However, the problem of serum swelling can usually be relieved by three times of drainage and pressure dressing, and then gradually heal.
