丛状神经纤维瘤内血窦丰富,手术出血较难控制,采用预先结扎局部血管及控制性低血压等措施减少失血。丛状神经纤维瘤一般占据面积较大,切除后常用游离植皮、皮瓣或皮管修复,术后皮肤质量差,疤痕明显或较臃肿,经采用瘤体真皮下血管网皮瓣修复,节约了皮源,避免了皮片移植造成的环状疤痕和皮瓣、皮管移植后的臃肿外形,效果较好。 The sinusoidal neurofibroma is rich in sinusoids, surgical hemorrhage is difficult to control, and blood loss is reduced by preliminarily ligating local blood vessels and controlled hypotension. Plexus neurofibromas generally occupy a larger area, after removal of the skin graft, skin flap or skin repair, postoperative skin quality is poor, scars are obvious or more bloated, the use of the tumor subdermal vascular network flap repair, saving The skin source avoids the circular scars and skin flaps after the skin grafting and the blister shape after the skin grafting. The effect is better.
