A novel technique for the reconstruction of infected full-thickness chest wall defects.

BACKGROUND: Chest wall resection and reconstruction can be performed with minimal mortality and excellent functional and cosmetic results using synthetic meshes, methylmethacrylate, or other substitutes. However, these techniques are less easily applicable if chest wall resections have to be performed for infections. METHODS: We report a novel technique for this purpose using a modified latissimus dorsi flap harvested in continuity with the thoracolumbar fascia. The vascularized fascia was sutured into the chest wall defect, providing a stable base for the muscular component of the flap. Three patients requiring large full-thickness resections of the anterolateral chest wall for chronic infections were treated accordingly, two presenting with chronic radionecrosis and osteomyelitis and one with chest wall invasion by pulmonary aspergillosis. RESULTS: There were no intraoperative or postoperative complications and immediate extubation was possible in all 3 patients without the need for postoperative ventilation or tracheotomy. Healing of the infected chest wall was observed in all 3 patients. Postoperative cinemagnetic resonance imaging revealed concordant movements of the replaced segments without evidence of paradoxical motion during inspiration and expiration. CONCLUSIONS: This technique is easy and safe. It allows a stable and satisfactory reconstruction after large anterolateral full-thickness chest wall resections of infected, previously irradiated tissues, using only well-vascularized autologous tissue.     

Using the costal muscle flap with latissimus dorsi muscle to repair full-thickness anterior chest wall defects

Musculoosseous flaps with latissimus dorsi muscle are used for reconstruction of full-thickness anterior chest wall defects. The 11th and 12th ribs and the posterior parietal pleura are elevated with the latissimus dorsi muscle. The blood supply of the compound flap comes from the thoracodorsal pedicle and from perforating segmental vessels. The posterior thoracic wall island is transferred to the anterior chest wall defect to restore a skeletal plane and the transposed latissimus dorsi obliterates all the dead spaces that cannot be collapsed. The latissimus dorsi compound flap with the 11th and 12th ribs appears to be a "safe" procedure to reconstruct full-thickness anterior chest wall defects.     

Reconstruction of full-thickness chest wall defects using rectus abdominis musculocutaneous flap: a report of fifteen cases

In 15 patients chest walls were excised because of recurrent breast cancer, radiation ulcer, or rib tumor. In most cases the full-thickness defect of the chest wall was about 10 x 10 cm. Reconstruction was performed using only a rectus abdominis musculocutaneous flap. No patient developed circulation problems in the flap or severe flail chest, and we had successful results in all our cases. These results show that the rectus abdominis musculocutaneous flap is quite effective and safe to use in the reconstruction of chest wall defects.     

Reconstruction of full thickness chest wall defects.

Over the last 5 years, 14 patients were treated by wide en bloc resection of chest wall tumors with primary reconstruction. There were nine females and five male patients with an age range of 31-77 years. All patients had a skeletal resection of the chest wall. An average of 3.9 ribs were resected in the patients treated. In three patients a partial sternectomy was carried out in conjunction with the rib resections. Chest wall skeletal defects were reconstructed with Prolene mesh, which was placed under tension. Soft tissue reconstruction utilized selected portions of the latissimus dorsi musculocutaneous territory with fasciocutaneous extensions beyond the muscle itself. Primary healing was obtained in all patients and secondary procedures were not required. The average hospitalization was 23 days. All patients survived the resection and reconstruction and were alive 30 days after operation. In selected patients the preservation of a portion of the innervated muscle in situ or the transfer of the muscle with the preservation of its resting length has maintained the majority of the muscle function.     

Diaphragm mobilization for closure of chest wall defects

Locally disseminated breast carcinoma after a simple or radical mastectomy and radiotherapy causes serious surgical problems. Excision of the chest wall obliterates the negative intrapleural pressure, and wound healing within a previously irradiated area is notoriously poor. A new method is described in which the diaphragm is mobilized and reinserted into the defect to allow final resurfacing with a skin graft or locally rotated skin flap. This simple surgical method is advocated when the prognosis is poor and breast reconstruction is not being considered.     

A free fibula autologous transfer for a full-thickness anterior chest wall defect

Large defects of the anterior chest wall lead to gross chest instability which can result in paradoxical respiration. Skeletal stabilization is an essential requirement in such cases. The current methods for achieving total or near total sternal reconstructions involve the use of alloplastic implant materials: prosthetic mesh with methyl methacrylate. In our experience, this method of reconstruction is often complicated by a persistent seroma and infection. A large full-thickness sternal defect was reconstructed by an osteotomized free fibula "Z" transfer and bilateral bipedicled pectoralis major myocutaneous flaps. This case highlights the use of vascularized autologous tissue for a complex full-thickness anterior chest wall reconstruction.     

Combined reconstruction of complex defects of the chest wall

Defects of the chest wall are often encountered, and good results can be obtained both cosmetically and functionally from their treatment. We treated 13 patients with full thickness chest wall defects. Follow up ranged from 12 days to 19 months. Three had had recurrent breast carcinoma, seven relapse after excision of a sarcoma, two had had lesions of the chest wall after irradiation, and one had a sternal fistula. Local skin, musculocutaneous and free latissimus dorsi and anterolateral thigh flaps were done to cover soft tissue. Fascia lata, polypropylene (Marlex®) mesh, and Marlex® mesh-methylmethacrylate sandwich prosthesis, were used to stabilise the skeleton in nine patients. Two of the patients died postoperatively, one early. The use of Marlex® mesh-methylmethacrylate sandwich prostheses for the stabilisation of the skeleton and local musculocutaneous flaps for covering soft tissues after resection of three or more ribs is effective.     

Efficiency of the combination of Mersilene-musculocutaneous flap in the reconstruction of full-thickness chest wall defects. A retrospective study of 14 cases

SUBJECT: The tumors of chest wall can be responsible of large full-thickness defects. The skeletal stabilization by different synthetic materials with numerous modalities of use and the superficial coverage of the defect by a musculocutaneous flap are the two imperatives parts of this reconstruction. PATIENTS AND METHODS: From January 1997 to January 2006, 14 patients, 10 males and 4 females, aged between 17 and 63 years old and suffering from full-thickness chest wall defects secondary to tumor resection have benefited from a simple reconstruction, wherever the defect, by a Mersilene Mesh and a muscular or musculocutaneous flap. These defects measured between 8 x 12 cm and 14 x 16 cm and were located in the anterior part of the chest in 3 cases, with resection of the upper half of the sternum and the internal part of both clavicles and the first three ribs, and in the lateral part of the chest in 11 cases with resection between 3 and 5 ribs. The histological diagnoses of these tumors were 3 chondrosarcomas, 3 sternum and 1 rib metastases, 2 desmoid tumors, 1 Ewing's sarcoma, 4 benign tumors. The flaps used were pedicled in 13 cases and based on the latissimus dorsi muscle, the serratus muscle and the pectoralis major muscle; in 1 case, the latissimus dorsi musculocutaneous flap was free. RESULTS: The skeletal stabilisation seems satisfying. There was no problems with the pulmonary function except in 4 cases where a dyspnea appears in sustained effort. No vascular complication on these flaps was noted. With a mean follow up of 46 months, there was no local recurrence of the malignant tumors. Two patients were deceased 1 year after surgery.0. CONCLUSION: The Mersilene mesh associated with a locoregional musculocutaneous flap represent a simple and efficient solution for the treatment of such defects.     

Extended myofascial thigh flaps for repair of large full-thickness abdominal wall defects

The large, full-thickness abdominal wall defect encompassing the upper and lower quadrants can test the surgeon's ingenuity in providing definitive repair. Two cases are reported of this type of abdominal wall defect closed in one stage using an extended tensor fascia lata myofasciocutaneous flap and an extended rectus femoris myofascial flap, respectively. In addition, a fresh cadaver dye injection study demonstrates the extensive circulatory pattern of these flaps.     

Treatment of full-thickness abdominal and chest wall losses with split-thickness skin grafting.

A 22-year-old man developed a large abdominal wall and sternal defect resulting from wound dehiscence. This was a sequel to two operations for gunshot wounds of the abdomen, the second one being for intraperitoneal abscess. The infected dehiscence was treated by the open method using povidoneiodine (Betadine) packs. As soon as the patient's condition permitted, split-thickness grafts were applied to the defect. One hundred percent success resulted, and convalescence of this critically ill patient was thereafter uninterrupted until discharge 31 days later. It is the authors' opinion that this method has a wider application than it is usually accredited.
