Reconstruction of complex thoraco-abdominal defects with extended anterolateral thigh flap

Background:

The reconstruction of complex thoraco-abdominal defects following tumour ablative procedures has evolved over the years from the use of pedicle flaps to free flaps. The free extended anterolateral thigh flap is a good choice to cover large defects in one stage.

Materials and Methods:

From 2004 to 2009, five patients with complex defects of the thoracic and abdominal wall following tumour ablation were reconstructed in one stage and were studied. The commonest tumour was chondrosarcoma. The skeletal component was reconstructed with methylmethacrylate bone cement and polypropylene mesh and the soft tissue with free extended anterolateral thigh flap. The flaps were anastomosed with internal mammary vessels. The donor sites of the flaps were covered with split-skin graft.

Result:

All the flaps survived well. One flap required re-exploration for venous congestion and was successfully salvaged. Two flaps had post operative wound infection and were managed conservatively. All flap donor sites developed hyper-pigmentation, contour deformity and cobble stone appearance.

Conclusion:

Single-stage reconstruction of the complex defects of the thoraco-abdominal region is feasible with extended anterolateral thigh flap and can be adopted as the first procedure of choice.     

Monitoring a free anterolateral thigh flap for pharyngeal reconstruction

Aim: To describe a novel way of monitoring a buried fasciocutaneous anterolateral thigh (ALT) flap used for pharyngeal reconstruction. Methods: A tubed ALT flap was used to reconstruct a circumferential pharyngeal defect following resection of a carcinoma. An island of skin based on a separate perforator and externalized through the neck incision was used to monitor the flap. It was removed as a bedside procedure on the fifth postoperative day. Results: The externalized skin island allowed easy monitoring of the buried tubed free‐flap used to reconstruct the pharynx. Simple clinical parameters such as temperature, colour and capillary refill were used to monitor the flap instead of more complex and invasive methods. Conclusion: When feasible, a second skin island based on a separate set of perforator vessels provides an easy, safe and simple method of monitoring a buried free‐flap.     

Computed tomography angiography imaging for the chimeric anterolateral thigh flap in reconstruction of full thickness buccal defect

Background: Microvascular free flap transplantation is the current most common choice for reconstruction of difficult through‐and‐through buccal defect after cancer extirpation. The chimeric anterolateral thigh (ALT) flap is an ideal flap to cover this full thickness defect, but variation in the location of perforators is a major concern. Herein, we introduce computed tomographic angiography (CTA)‐guided mathematical perforators mapping for chimeric ALT flap design and harvest. Methods: Between September 2008 and March 2009, nine patients with head and neck tumour underwent preoperative CTA perforator mapping before free ALT flap reconstruction of full thickness buccal defects. The perforators were marked on a 64‐section multi‐detector CT image for each patient, and the actual perforator locations were correlated with the intra‐operative dissection. The donor limb of choice, either right or left, was also selected based on the dominant vascularity. Flap success rates, any associated morbidity and complications were recorded. Results: A total of 23 perforators were identified on CTA image preoperatively. Twenty‐two of these perforators were chosen for chimeric flap design, and all were located as the CTA predicted, with the rate of utilization being 95.7% (22/23). There were two post‐operative complications, including one partial flap necrosis and one microstomia. All of the ALT flaps survived, and there was no donor site morbidity. Conclusions: Preoperative CTA allows accurate perforator mapping and evaluation of the dominant vascularity. It helps the surgeon to get an ideal designing of the chimeric ALT flap with two skin paddles based on individual perforators, but only one vascular anastomosis in reconstruction of full thickness buccal defects.

Functional outcomes after laryngopharyngectomy with anterolateral thigh flap reconstruction

BACKGROUND: We examined speech and swallowing outcomes and complications in patients with anterolateral thigh (ALT) flap reconstruction of cervical esophageal defects. METHODS: We retrospectively reviewed 29 patients treated with laryngopharyngectomy and ALT flap reconstruction at The University of Texas M. D. Anderson Cancer Center from March 2002 to July 2004. We compared complication rates, nutritional intake, number of tracheoesophageal punctures (TEPs), speech fluency and use, operative defects, and radiotherapy effects. RESULTS: Twenty-two patients had circumferential defects, and seven had partial defects. Twenty-four patients had radiotherapy. Eleven patients underwent TEP. Higher complication rates in patients after TEP compared with those without TEP were not statistically significant (p = .268). Ninety percent of patients with TEP spoke fluently. Ninety percent of all patients returned to oral alimentation without significant effect from TEP (p = 1.00), complications (p = 1.00), radiation therapy (p = 1.00), or surgical defect (p = .56). CONCLUSIONS: The ALT flap successfully reconstructs laryngopharyngeal defects with excellent speech and swallowing results.

First web-space reconstruction by the anterolateral thigh flap

Four patients with severe contracture of the first web space were treated with an anterolateral thigh perforator flap. The flap size ranged from 10 to 13 cm in length and from 7 to 8 cm in width. The donor site was closed directly and thinning of the flap was performed in all cases. All flaps survived and there were no re-explorations. Web space opening was maintained over the follow-up period. There was an average postoperative increase of the angle of the first web space of 61 degrees. The thinned anterolateral thigh flap provides a pliable vascularized tissue for resurfacing the skin after release of severe contracture of the first web space and represents a reliable alternative to other flaps.

Reversed anterolateral thigh adipofascial flap for knee and proximal calf defects

BACKGROUND: Reconstruction of defects involving the knee and proximal one third of the lower leg presents a challenging problem in plastic surgery. AIM: To evaluate the reversed anterolateral thigh adipofascial flap for covering such defects. METHODS: Between September 2006 and May 2007, one man and four women with defects around the knee and upper calf underwent reconstruction with reversed anterolateral thigh adipofascial flaps. The patients' average age was 45 years (25-72 years). The size of the transferred flap ranged from 6cmx8cm to 12cmx13cm. RESULTS: Four flaps with overlying skin grafts healed uneventfully; one skin graft showed minor necrosis due to haematoma, but the adipofascial flap survived well. Postoperatively the appearance of the reconstructive flap was acceptable. CONCLUSIONS: The reversed anterolateral thigh adipofascial flap is an effective option for covering defects of the knee and proximal calf.
