  • Title: Reconstruction of an external hemipelvectomy defect with a two-stage fillet of leg-free flap.
    Author: Boehmler JH, Francis SH, Grawe RK, Mayerson JL.
    Journal: J Reconstr Microsurg; 2010 May; 26(4):271-6. PubMed ID: 20169526.
    Abstract:
    The defect created by external hemipelvectomy for bone and soft tissue tumor resection is a challenge to reconstruct because of the exposure of bone, neurovascular structures, and peritoneal contents, particularly in the setting of previous radiotherapy. In a nonsalvageable limb with extensive tumor involvement and radiation damage, a free fillet of leg flap can be used to provide the necessary large volume of tissue for reconstruction without donor site morbidity. Because of the lengthy operative time for the hemipelvectomy procedure, the fillet of leg flap may be subject to long ischemia time and a subsequently compromised outcome. A two-stage fillet of leg flap for a hemipelvectomy defect was performed with two goals: to decrease ischemia time and to allow the necessary resuscitation of the patient between operative stages. Stage one was dissection of a lower fillet of leg flap, transfer and anastomosis to the contralateral femoral vessels, and temporary inset in the groin. The patient and flap were observed in the intensive care unit for several days. The patient returned to the operating room 3 days later for staged external hemipelvectomy and inset of the viable fillet of leg flap. Throughout follow-up, the reconstructive results and functional outcome were excellent.
