Clinical Significance of the Rectus Abdominis Muscle Free Flap for Large Diabetic Ulcer and Necrosis of the Foot

The purpose of this study was to present the clinical significance of rectus abdominis free muscle flap for large sized diabetic ulcer and necrosis of the foot to salvage limb. From June 2000 to February 2006, eleven patients were included in our study. There were seven males and four females with a mean age of 58.3 years (48~65) at the surgery. All had a history of diabetics and subsequent huge soft tissue defect caused by necrotizing abscess formation around the foot and the ankle. After complete debridement of large sized, infected necrotic tissue, susceptible intravenous antibiotics and wound care were done. After control of infection, confirmed by clinical and laboratory findings, the rectus abdominis free muscle flap was applied to cover remained large soft tissue defect and to prevent the recurrence of infection. All flaps survived and it provided satisfactory coverage for the soft tissue defect on the foot and the ankle area for a mean of 41.1 months (24~85) follow up period. All except of one patients did not have any recurrence of infection on the operation site and could salvage their limbs. The rectus abdominis free muscle flap could be recommended for large sized soft tissue defect after necrotizing abscess in diabetic foot to salvage major limb.

Management of Post-lobectomy Bronchopleural: Cutaneous Fistula with a Rectus Abdominis Free Flap

PURPOSE: The repair of complex chest wall defects presents a challenging problem for the reconstructive surgeon. In particular, a free flap is often required when the defect is large, in which case suitable recipient vessels must be found to insure revascularization. The authors report a case of persistent bronchopleural-cutaneous fistula developed after undergoing lobectomy for lung cancer. METHODS: The defect area was repaired using a free vertical rectus abdominis muscle flap revascularized by microvascular anastomosis to the 6th intercostal pedicle. The flap obliterated the right chest cavity, closed the site of empyema drainage, and aided healing of a bronchopleuralcutaneous fistula. RESULTS: The patient has remained healed for 14 months without any postoperative complications or recurrent infection or fistula. CONCLUSION: We suggest that a rectus abdominis musculocutaneus free flap and intercostal pedicle as a recipient could be a useful method for repair of chest defects.

Rectus Abdominis Free Flap Reconstruction for Orbital-Maxillary Defect in Advanced Maxillary Sinus Cancer / 대한이비인후과학회지

In the management of advanced maxillary sinus cancer, sometimes it requires an extensive ablation and orbital exenteration that results in large and full defects of the cheek and orbital regions. Reconstruction of large orbital-maxillary defects can be accomplished in one stage by microsurgical free transfer of rectus abdominis myocutaneous flap. The muscle component is suitable to fill the orbital and maxillary cavities, and the skin components are used for cheek, palate and lateral nasal cavity wall reconstruction as a three-dimentional folded free flap. Major problems with this flap are the bulkiness, the possibility of abdominal hernia and muscle weakness following the removal of the rectus abdominis muscle. Free deep inferior epigastric artery skin flap without rectus abdominis muscle is available in the reconstruction of large orbital-maxillary defect without the problems of the rectus abdominis myocutaneous free flap. We experienced one case of rectus abdominis myocutaneous free flap, and one other case of inferior rectus abdominis free flap for the reconstruction of huge surgical defects due to radical maxillectomy with orbital excenteration. Both of the patients were satisfied and there have been no severe complication associated with these technique.
