Gluteal Soft Tissue Necrosis After Transcatheter Angiographic Embolization for Pelvic Fracture: a Report of Two Cases.

In this paper, two cases of the gluteal soft tissue necrosis after pelvic fractures will be discussed. In the case of a 29-year-old man, a localized area of skin necrosis on the buttock appeared after transcatheter arterial embolization (TAE) of the right internal iliac artery (IIA). In the second case, a 52-year-old man, who was treated using TAE of the bilateral IIA's, developed an extensive area of necrosis in the gluteus maximus muscle with subsequent severe infection. In both cases, complete excision of the necrotic tissue and reconstructive flap surgery were imperative. Gluteal soft tissue necrosis is clinically important as one of the serious complications of TAE.
