Anterolateral Thigh Twin Free Flaps from a Single Donor Site-a Modification Based on the Oblique Branch of the Lateral Circumflex Femoral Artery.

The pedicle of the anterolateral thigh flap is formed by the descending branch of the lateral circumflex femoral artery. Recently, an oblique branch of lateral circumflex femoral artery was described by Wei et al., which can also be used as an alternative to the descending branch. We describe a case in which both the pedicles were used to create two free flaps (twin flaps) from the same thigh for post tumour reconstruction of breast.

Skin paddle vascularity of free fibula flap - A study of 386 cases and a classification based on contribution from axial vessels of the leg.

OBJECTIVE: The skin paddle of the free fibula flap receives its vascular supply from septocutaneous perforators, musculocutaneous perforators or from both, and these perforators might originate from the peroneal or posterior tibial vessels or from both. The objective of this study was to classify the skin paddles based on the dominance of vascular contribution by these axial vessels through their different perforator systems. MATERIALS AND METHODS: A retrospective analysis of 5-year data of 386 free fibula flaps used in oro-mandibular reconstruction was done and the skin paddle vascularity was studied. While majority of the skin paddles received their blood supply from the peroneal septocutaneous perforators, a few had their dominant supply from the soleus musculocutaneous perforators in addition to peroneal septocutaneous perforators. In few cases, the soleus musculocutaneous perforators were the sole source of blood supply to the skin paddle. The limitation in this study was the inability to augment the clinical observation with cadaveric study. RESULTS: The skin paddle of the free fibula flap was classified into four different types (a-d) based on the dominance of vascular contribution by axial vessels of the leg. CONCLUSION: The skin paddle of the free fibula flap has reliable blood supply, but a thorough knowledge of the variations in vascular pattern of the skin paddle is required especially to salvage the larger paddles used in the reconstruction complex oro-mandibular defects.

Reconstruction of oncological oro-mandibular defects with double skin paddled-free fibula flap: a prudent alternative to double flaps in resource-constrained centres.

OBJECTIVE: The free fibula flap is the choice flap for mandibular reconstruction following extensive tumor resections. While large defects are managed with a second flap [free or pedicle] in advanced centres, a free fibula flap with a large skin paddle that can be de-epithelised to provide outer skin and inner lining is the best alternative in resource- constrained centres. MATERIALS AND METHODS: From January 2005 to December 2009 a total of 386 free fibula flaps were used of which 307 flaps had de-epithelised double skin paddle in reconstructing complex oral and mandibular defects after tumor ablative surgeries. RESULTS: Complete flap survival was seen in 282/307 patients. Complete flap loss was seen in 9/307 patients. Partial flap loss was seen in 16 patients. Re - exploration was done in 30 patients and the flap was salvaged in 21 patients. CONCLUSION: The vascular supply of the free fibula osteo myocutaneous flap is reliable and a flap with a large skin paddle can be used to provide both inner lining and outer cover in resource-constrained centres.

Pedicle transfer in oral cavity reconstruction.

In head and neck reconstructions when a free flap is used intra orally to provide the lining its vascular pedicle has to be transferred to the neck for anastomosis. This has to be performed in such a way that the pedicle does not get kinked or twisted. The pedicle is enrolled in a split open glove from its point of entry into the flap till its proximal most part. In order to prevent twisting of the vessels and to maintain orientation, the glove is wrapped in such a way that the imprint on the glove is on the visualized surface. The glove wrapped pedicle is passed from inside the oral cavity while an artery clamp passed from the neck wound through the submandibular or subcutaneous tunnel holds the tip of the glove component and guides it safely to the neck without exerting any traction on the flap or the pedicle vessels.

Utility of proximally based sural artery flap for lower thigh and knee defects.

The proximally based sural artery flap presents distinct advantages in reconstruction of knee and lower thigh defects including thin sensate flap, reduced donor-site morbidity with good aesthetic outcome. However there are few reports in the literature regarding this flap. This study presents our experience with use of this flap in 37 patients. A retrospective study was performed over a 6-year period (from January 2003 to October 2008) using proximally based islanded sural artery flap for the lower thigh, knee, and upper leg defects following tumor excision defects. There were no complete failures in the series with only one flap requiring additional bipedicled flap for the necrosis of distal margin. All donor sites were closed with split thickness skin graft, with skin paddle sizes ranging up to 23 x 10.5 cm. All patients achieved a good final outcome. The authors found the proximally based islanded sural artery flap to be a simple and reproducible technique to perform and have greater reach up to the lower thigh. It provides thin pliable skin with minimal compromise to either appearance or function. The flap is suitable in the regional reconstruction around the knee as a pedicled flap.

Pedicled anterolateral thigh flap: a versatile flap for difficult regional soft tissue reconstruction.

Reconstruction of extensive oncosurgical defects of lower trunk, perineum and upper thigh, without the complexity of microsurgery, is a reconstructive challenge. Pedicled anterolateral thigh (ALT) flap offers many advantages over other regional flaps for this purpose, such as the large skin and soft tissue availability, the remarkable pedicle length and the reliability. However, there is paucity of literature describing the utility of pedicled ALT flaps for reconstruction of these difficult soft tissue defects. We present our experience of pedicled ALT flaps for various post oncosurgical defects. From January 2005 to August 2008, 85 pedicled ALT flaps were done in 78 patients for post oncological excision defects of lower trunk, groin, perineum, and upper thigh. Majority of patients were males, with locally advanced inguinal disease, underwent wide skin excision and en bloc nodal resection. Age group ranged from 22 to 81 years. The flap size ranged from 10 x 5 cm (50 cm) to 38 x 20 cm (760 cm). The length of the pedicle ranged from 8 to 14 cm. Satisfactory coverage was achieved in all patients, except one, where the flap had to be discarded due to absent artery in the vascular pedicle. Clinically, no functional deficit of knee extensor mechanism was seen in any of these patients during routine activities. Present study has shown the wide arc of rotation, large skin replacement potential, and reliability of pedicled ALT flap.

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.

There is no donor side specificity of fibula free flap for complex oromandibular reconstruction.

BACKGROUND: The objective of this study was to prove that there is no significance to the donor side (right or left) of the free fibula osteocutaneous flap (FFOCF) in the reconstruction of complex oromandibular defects (COMD) and proper flap planning, designing and tailoring are important in reconstructing different types of COMD after tumour-ablative surgery. MATERIALS AND METHODS: Three hundred and eighty-six consecutive patients who where reconstructed with FFOCF for COMD from Jan 2005 to Dec 2009 over a period of 5 years were studied. Except in seven patients, all fibula flaps were harvested from the left leg as per convenience and to facilitate a simultaneous, two-team approach. Depending on the condition of the neck vessels, vascular anastomosis was performed on the right or the left side, irrespective of the side of the defect. RESULTS: Complete flap survival was seen in 334 patients (86.52%). Superficial skin necrosis was seen in 20 patients, and was managed conservatively (5.18%). Partial flap loss was seen in 20 patients (5.18%). There were 39 re-explorations. Complete flap loss was seen in 12 patients (3.10%). CONCLUSION: We found no significance in terms of the results as far as the side of flap donor leg or primary defect were concerned. Flap tailoring in terms of meeting the tissue requirement and vessel orientation were rather more important.

Successful management of free osteocutaneous fibula flap with anomalous vascularity of the skin paddle.

The free osteocutaneous fibula flap is an established method of reconstruction of maxillary and mandibular defects. The vascularity of the skeletal and the cutaneous components is provided by the peroneal artery via the nutrient artery and the septo- and musculocutaneous perforators. In rare situations, these perforators may arise from other major leg arteries. In such circumstances, the procedure has to be either abandoned or modified so that neither the vascularity of the flap nor the donor limb is compromised. We present a case of an anomalous musculocutaneous perforator, which originated from the proximal part of the posterior tibial artery, passed through the soleus muscle and supplied the skin paddle. The flap was elevated as a single composite unit and was managed by two separate vascular anastomosis at the recipient site, one for the peroneal vessels and the other for the anomalous perforator.
