RESUMO
BACKGROUND: Multi-territory perforator flap reconstruction has been proven effective in treating large skin and soft tissue defects in clinical settings. However, in view of that the multi-territory perforator flap is prone to partial postoperative necrosis, increasing its survival is the key to the success of reconstruction. In this study, we aimed to clarify the effect of emodin on multi-territory perforator flap survival. METHODS: Flap survival was assessed by viability area analysis, infrared laser imaging detector, HE staining, immunohistochemistry, and angiography. Western blotting, immunofluorescence assays, and real-time fluorescent quantitative PCR were performed to detect the indicators of oxidative stress, pyroptosis and autophagy. RESULTS: After emodin treatment, the multi-territory perforator flap showed a significantly increased survival rate, which was shown to be closely related to the inhibition of oxidative stress and pyroptosis and enhanced autophagy. Meanwhile, the use of autophagy inhibitor 3 MA was found to reverse the inhibitory effects of emodin on oxidative stress and pyroptosis and weaken the improving effect of emodin on flap survival, suggesting that autophagy plays a critical role in emodin-treated flaps. Interestingly, our mechanistic investigations revealed that the positive effect of emodin on multi-territory perforator flap was attributed to the mTOR-ULK1 signaling pathway activation. CONCLUSIONS: Emodin can inhibit oxidative stress and pyroptosis by activating autophagy via the mTOR-ULK1 pathway, thereby improving the multi-territory perforator flap survival.

Perforator flap magnetic resonance angiography (MRA) has emerged as a widely accepted and preferred modality for perforator flap mapping at several institutions. Autologous perforator flaps are a type of reconstructive microsurgical technique that involves transferring skin and fat from one part of the patient's body to another to replace tissue lost due to trauma, cancer resection, or other reasons. Autologous perforator flaps are based on a specific perforating blood vessel perfusing the transferred tissue. Hence, the surgery relies on the precise identification and mapping of perforating vessels to ensure successful outcomes. With its superior soft tissue contrast and multiplanar imaging capabilities, MRA has shown great potential in providing accurate and detailed visualization of perforator anatomy, size, and course. This review article summarizes the current literature on perforator flap MRA, including its technical considerations, imaging protocols, postprocessing, and reporting, specifically for autologous breast reconstructions. The advantages and limitations of MRA in evaluating perforator flaps are discussed, including its role in preoperative planning, intraoperative guidance, and postoperative assessment. Anatomy, brief surgical technique, specific technical modifications, and reporting of most commonly performed autologous breast flaps are described. Recent advancements in Perforator flap surgery and MRA techniques are discussed. Additionally, we examine the emerging role of artificial intelligence and machine learning in improving the accuracy and efficiency of perforator flap MRA interpretation. LEVEL OF EVIDENCE: 5 TECHNICAL EFFICACY: Stage 5.

BACKGROUND: The efficacy and safety of perforator-based propeller flaps (PPF) versus free flaps (FF) in traumatic lower leg and foot reconstructions are debated. PPFs are perceived as simpler due to advantages like avoiding microsurgery, but concerns about complications, such as flap congestion and necrosis, persist. This study aimed to compare outcomes of PPF and FF in trauma-related distal lower extremity soft tissue reconstruction. METHODS: We retrospectively studied 38 flaps in 33 patients who underwent lower leg and foot soft tissue reconstruction due to trauma at our hospital from 2015 until 2022. Flap-related outcomes and complications were compared between the PPF group (18 flaps in 15 patients) and the FF group (20 flaps in 18 patients). These included complete and partial flap necrosis, venous congestion, delayed osteomyelitis, and the coverage failure rate, defined as the need for secondary flaps due to flap necrosis. RESULTS: The coverage failure rate was 22% in the PPF group and 5% in the FF group, with complete necrosis observed in 11% of the PPF group and 5% of the FF group, and partial necrosis in 39% of the PPF group and 10% of the FF group, indicating no significant difference between the two groups. However, venous congestion was significantly higher in 72% of the PPF group compared to 10% of the FF group. Four PPFs and one FF required FF reconstruction due to implant/fracture exposure from necrosis. Additionally, four PPFs developed delayed osteomyelitis post-healing, requiring reconstruction using free vascularized bone graft in three out of four cases. CONCLUSIONS: Flap necrosis in traumatic lower-leg defects can lead to reconstructive failure, exposing implants or fractures and potentially causing catastrophic outcomes like osteomyelitis, jeopardizing limb salvage. Surgeons should be cautious about deeming PPFs as straightforward and microsurgery-free procedures, given the increased complication rates compared to FFs in traumatic reconstruction.

OBJECTIVE: To evaluate the clinical effectiveness of antibiotic bone cement combined with the lobulated perforator flap based on the descending branch of the lateral circumflex femoral artery (d-LCFA) in the treatment of infected traumatic tissue defects in the foot, in accordance with the Enhanced Recovery after Surgery (ERAS) concept. METHODS: From December 2019 to November 2022, 10 patients with infected traumatic tissue defects of the foot were treated with antibiotic bone cement combined with the d-LCFA lobulated perforator flap. The cohort comprised 6 males and 4 females, aged 21 to 67 years. Initial infection control was achieved through debridement and coverage with antibiotic bone cement, requiring one debridement in nine cases and two debridements in one case. Following infection control, the tissue defects were reconstructed utilizing the d-LCFA lobulated perforator flap, with the donor site closed primarily. The flap area ranged from 12 cm×6 cm to 31 cm×7 cm. Postoperative follow-up included evaluation of flap survival, donor site healing, and ambulatory function of the foot. RESULTS: The follow-up period ranged from 7 to 24 months, averaging 14 months. Infection control was achieved successfully in all cases. The flaps exhibited excellent survival rates and the donor site healed by first intention. Based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, pain and function were evaluated as excellent in 3 cases, good in 5 cases, and moderate in 2 cases. CONCLUSION: The application of antibiotic bone cement combined with the d-LCFA lobulated perforator flap is an effective treatment for infected traumatic tissue defects of the foot with the advantages of simplicity, high repeatability, and precise curative effects. The application of the d-LCFA lobulated perforator flap in wound repair causes minimal damage to the donor site, shortens hospital stays, lowers medical expenses, and accelerates patient rehabilitation, aligning with the ERAS concept. Therefore, it is a practice worth promoting in clinical use.

Avascular necrosis frequently occurs as a complication following surgery involving the distal perforator flap. Dihydrocapsaicin (DHC) can protect tissue from ischemia-reperfusion (I/R) injury, but its specific role in multizone perforator flaps remains unclear. In this study, the prospective target of DHC in the context of I/R injury was predicted using network pharmacology analysis. Flap viability was determined through survival area analysis, laser Doppler blood flow, angiograms, and histological examination. The expressions of angiogenesis, apoptosis, NLR family pyrin domain containing 3 (NLRP3) inflammasome, oxidative stress, and molecules related to cyclic guanosine monophosphate (GMP)-adenosine monophosphate synthase (cGAS)-interferon gene stimulant (STING) pathway were assessed using western blotting, immunofluorescence, TUNEL staining, and dihydroethidium (DHE) staining. Our finding revealed that DHC promoted the perforator flap survival, which involves the cGAS-STING pathway, oxidative stress, NLRP3 inflammasome, apoptosis, and angiogenesis. DHC induced oxidative stress resistance and suppressed the NLRP3 inflammasome, preventing apoptosis in vascular endothelial cells. Through regulation of STING pathway, DHC controlled oxidative stress in endothelial cells and NLRP3 levels in ischemic flaps. However, activation of the cGAS-STING pathway led to the accumulation of reactive oxygen species (ROS) and NLRP3 inflammasome, thereby diminishing the protective role of DHC. DHC enhanced the survival of multidomain perforator flaps by suppressing the cGAS-STING pathway, oxidative stress, and the formation of NLRP3 inflammasome. These findings unveil a potentially novel mechanism with clinical significance for promoting the survival of multidomain perforator flaps.

PURPOSE: Autologous breast reconstruction improves patient satisfaction and quality of life after mastectomy. In Germany, free flap surgery and implant-based reconstruction is usually separate between reconstructive surgery and gynecology. Cooperation between the specialist disciplines and implementation of microsurgery into breast surgeon training could enhance surgical treatment for breast cancer patients. This evaluation is intended to demonstrate the learning progress within a microsurgical training program and the complication rate in relation to microsurgical experience. METHODS: At the breast cancer center at Klinikum rechts der Isar, TU Munich, a three-stage training program for autologous breast reconstruction and microsurgery for gynecological breast surgeons was developed. Between 2019 and 2022, 74 women received autologous free flap breast reconstruction by a consistent team consisting of a gynecological surgeon in training and an expert microsurgeon. Peri- and postoperative data were collected to analyze the feasibility and safety of a microsurgical training in gynecology. RESULTS: Within the training, operative steps of free autologous breast reconstruction were increasingly taken over by the gynecological surgeon in training. The analysis showed a decrease in operating times with consistently low complication rates during the training. CONCLUSION: This study demonstrated that a training in free autologous breast reconstruction for gynecological surgeons is safely feasible through close cooperation between gynecological and reconstructive surgery.

BACKGROUND: The thoracodorsal artery perforator (TDAP) flap has gained interest as a option for reconstruction of head and neck defects while minimizing donor site morbidity as compared to traditional workhorse flaps. The primary aim of this systematic review is to assess the postoperative outcomes and efficacy of this flap. METHODS: Several databases were screened for relevant citations. The quality of studies and risk of bias were evaluated using the MINORS scoring system. RESULTS: Twenty articles containing 168 patients undergoing at least one TDAP flap reconstruction met the inclusion criteria. There were no incidences of total flap failure and only 10 incidences of partial flap failure (5.95 %). Flap complications and donor site morbidity was low. The average MINORS score of the studies suggested a moderately high amount of bias. CONCLUSIONS: Based on limited quality evidence, this review suggests that TDAP flap is a safe and feasible option for head and neck reconstruction with comparable success rates as other commonly used flaps, with low complication rate and donor site morbidity. Further large-scale studies are warranted.

BACKGROUND: The descending genicular artery (DGA) and medial thigh region have been underused as donor sites for perforator flaps. This study evaluated the anatomical relationship between the perforators of the DGA and the saphenous vein (SV) to review the clinical applications of the free descending genicular artery perforator (DGAP) flap for locoregional reconstruction. METHODS: Fifteen cadavers were arterially perfused with red latex and dissected. Thirty-one patients with extremity tissue defects were treated with a free DGAP flap, including six patients who received a chimeric flap. The minimum distance between the DGAP and the SV was measured during surgery. RESULTS: In all patients, the skin branch of the descending genicular artery was found in the medial femoral condyle plane in front of the SV. The average distance between the descending genicular artery perforator and the SV was 3.71 ± 0.38 cm (range: 2.9-4.3 cm). Thirty flaps survived completely, and one flap developed partial necrosis; however, this flap healed two weeks after skin grafting. The average follow-up time was 11.23 months. CONCLUSIONS: We conclude that the SV can be preserved when harvesting the descending genicular artery perforator flap, causing less damage to the donor site and having no effect on flap survival. The free descending genicular artery perforator flap without the SV is a better therapy for complicated tissue defects.

Acupuncture has been proven an effective clinical treatment for numerous pathological conditions and malfunctions. However, substantial anatomical evidence for acupuncture points (APs) and meridians is still lacking, so the location of APs is relatively subjective and understanding of the biological mechanisms of acupuncture is limited. All these problems hinder the clinical applications and worldwide acceptance of acupuncture. Our long-term microsurgery experience has indicated that Perforating Cutaneous Vessels (PCVs) are highly relevant to APs but the anatomical evidence is insufficient. To address this lack, two specimens of fresh adult human upper limbs were dissected using an advanced vascular perfusion-fixation method and then examined. The results show that all 30 five-Shu APs in the upper limbs have corresponding PCVs. Both specimens showed a 100% coincidence rate between APs and PCVs, indicating that PCVs could be critical anatomical features of APs. This study also provides an anatomical basis for locating APs objectively via preliminary detection of PCVs. The findings could lead to a better theoretical understanding of mechanisms of acupuncture and the essence of meridians.

BACKGROUND: Breast-conserving surgery combined with oncoplastic breast surgery has become the standard surgical treatment for early breast cancer. OBJECTIVE: The purpose of this study was to investigate the safety and efficacy of the thoracodorsal artery perforator flap (TDAPF) in breast-conserving reconstruction of T2 breast cancer. METHODS: Thirty patients with T2 breast cancer admitted to our hospital from January 2019 to December 2020 were enrolled to receive pedicled TDAPF for repairing breast defects after breast-conserving surgery. Intraoperative conditions, postoperative complications, and shape satisfaction after breast reconstruction were recorded. RESULTS: The operation was successfully completed in all 30 patients, with an operation time of 177.77 ± 24.39 min, bleeding of 44.17 ± 7.67 mL, and length of hospital stay of 5.23 ± .97 d. There was no deformity or seroma at the donor site. Breast shape recovered well after operation. After operation, one patient had fat liquefaction in the recipient site, which healed well after wound treatment. The incidence of postoperative complications was 3.33%. Postoperative follow-up lasted 16-28 months, with a median of 22 months. The Breast-Q score for breast satisfaction was 61.83 ± 12.87 at 6 months after operation, compared to 62.07 ± 11.78 before operation (P > .05). CONCLUSIONS: TDAPF, featuring a high survival rate, moderate flap area, fewer postoperative complications, and high satisfaction with breast shape after operation. For east asian women with moderate breast size, TDAPF is a safe, effective choice for repairing defects in breast-conserving surgery for T2 breast cancer.

Vulvar loss of soft tissue leads to urinary, sexual and morphological dysfunctions. Most patients affected are comorbid making it difficult to perform a flap, which is the most appropriate way to reconstruct. Our multidisciplinary plastic and gynecologic surgery team has developed a new technique using a pedicled internal pudendal island flap. Reconstruction is reliable, quick and applicable to all patients, with a highly satisfactory final appearance.

Tracheoesophageal fistulas (TOF) following esophagectomy for esophageal cancer are rare but potentially fatal. There is no consensus on treatment between stenting and surgical repair, although the latter is associated with better distant survival. In surgical repair, the interposition of a flap improves healing by providing well-vascularized tissue and reinforcing the repair zone. The flaps described are usually muscular and decaying. We present the case of a malnourished fifty-year-old man who underwent intrathoracic surgical repair of symptomatic recurrent TOF using a skin flap based on the perforators of the internal thoracic artery (IMAP). The perforator flap was completely de-epidermized and tunneled under the sternum by a proximal and limited resection of the 3rd costal cartilage and placed at the posterior aspect of the trachea, with the excess tissue rolled up on either side. At 9 months, the patient showed no recurrence and improved general condition. The de-epidermized IMAP tunneled under the sternum intrathoracically is a reliable alternative to the conventional muscle flaps described in TOF management and an attractive additional tool in the plastic surgeon's surgical arsenal.

Flap-based reconstruction techniques have shown promise in preventing scar contractures and enhancing healing in fold areas by providing vascularized and thick tissue. We report a septic rupture of the superficial femoral artery treated with an arterial allograft and covered with a contralateral pedicled Deep Inferior Epigastric Artery Perforator (DIEP) flap. The patient presented favorable outcomes, including optimal healing at 8 months, with no functional limitation. A literature review also discusses alternative pedicled perforator flaps. These modern techniques present several advantages, including reliability, and can be of great interest in complex vascular surgery cases.

OBJECTIVES: To compare the clinical outcomes of anterolateral femoral interregional flap with turbocharge technique and traditional anterolateral femoral flap in repair of large limb wounds. METHODS: Clinical data of 38 patients with large limb surface wound (11 cm×39 cm-16 cm×65 cm) admitted to the Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from May 2018 to May 2022 were retrospectively analyzed. Eighteen patients were treated by anterolateral thigh perforator flap combined with superficial circumflex iliac artery flap (ALTP-SCIAP) with turbocharge technique (interregional flap group); while 20 patients were treated with unilateral or bilateral anterolateral femoral flaps, combined with skin grafting if necessary (traditional anterolateral femoral flap group). The survival of skin flap, repair of donor area, complications and patient satisfaction were compared between the two groups. RESULTS: In interregional flap group, 18 flaps were harvested and transplanted, the flap width, length and the viable area were (9.9±2.0) cm, (44.2±3.5) cm and (343.2±79.9) cm2, respectively. In traditional anterolateral femoral flap group, 29 flaps were harvested and transplanted, the flap width, length and the viable area were (11.0±2.8) cm, (21.7±3.2) cm and (186.4±49.2) cm2, respectively. There were significant differences in the flap length and the viable area between the two groups (t=22.365 and 8.345, both P<0.05). In the interregional flap group, the donor site of flap was closed by direct suture in 11 flaps, by skin retractor assisted suture in 6 flaps, and by skin grafting in one flap. In traditional anterolateral femoral flap group, the donor site of flap was closed by direct suture in 12 flaps, by skin retractor assisted suture in 11 flaps, and by skin grafting in 6 flaps. The skin graft rates of the two groups were 5.6% (1/18) and 20.7% (6/29), respectively (χ2=2.007, P>0.05). The interregional flap group had lower postoperative complications rate (5.6% vs. 35.0%, χ2=4.942, P<0.05) and higher patient satisfaction rate (94.4% vs. 70.0%, χ2=4.448, P<0.05) than traditional anterolateral femoral flap group. CONCLUSIONS: Compared with the traditional anterolateral femoral flap, the anterolateral femoral interregional flap with turbocharge technique has a larger flap area, most of the donor areas of the flap can be sutured directly without skin grafting and with less complications and a higher patient satisfaction rate.

Facial gunshots injuries remain challenging and present functional and aesthetic problems. Such defects generally require composite tissue flaps for reconstruction. Rebuilding the palate and the maxilla is especially delicate because it requires reconstitution of the facial buttresses, and replacement of bony hard palate, based on occlusion, as well as the restoration of the thin intraoral and intranasal lining which normally constitute the soft palate. Various methods of reconstruction have been applied to this area in search of an ideal soft tissue and bone flap to restore the bony framework of the maxilla and palate while providing an internal lining. The scapula dorsal perforator flap is used in the case of a patient to successfully reconstruct the palate, the maxilla and the nasal pyramid in one stage. Free tissue transfer using thoracodorsal perforator flaps and scapula bone free flap have been already described in literature but never to perform the nasal pyramid reconstruction at the same time. Good functional and aesthetic results have been obtained in this case. This article also reviews, through the authors experience and literature, anatomical landmarks, indications, technical surgical tricks, advantages and disadvantages of this flap for palatal, maxillary and nose reconstruction.

INTRODUCTION: Fournier's gangrene is a serious pathology with a high mortality rate. Treatment requires a large debridement of necrotized tissues, conducing to a skin loss, requiring a reconstruction, which may involve different surgical techniques, depending on the context as well as the size and location of the skin loss. The most common covering technique uses split-thickness skin grafting, which however presents a risk of contracture. CASE: Our 63 years old patient presented a Fournier's gangrene, leading to pubic and circular penile skin defects after multiple debridements. We decided to practice a right superficial circumflex iliac perforator (SCIP) pedicled flap to reconstruct the penile skin sheath. The flap was rotated 180 degrees and rolled around the penis. DISCUSSION: The inguinal pedicle flap is described for penile reconstruction, the SCIP flap for perineal reconstruction, and even bilateral SCIP flaps for performing phalloplasty, but SCIP pedicled flap is not already described for isolated penile skin sheath reconstruction. Skin loss in our patient was not extensive, permitting us to perform this surgical technique. To go further, note the possibility of carrying out this reconstruction by a super-thin SCIP flap, as a pure skin graft flap. CONCLUSION: The SCIP pedicled flap seems us to be a safe technique for penile skin reconstruction and a good alternative to the usual skin grafts, especially regarding the lower risk of contracture, and low donor-site morbidity.

BACKGROUND: The advent of propeller flaps has permitted new and less invasive coverage solutions for thoracic defects compared to conventional flaps. Through a retrospective analysis of our cases, we would like to show the advantages of the internal mammary artery perforator (IMAP) flap for anterior chest wall reconstruction. METHODS: We included patients who underwent anterior chest wall reconstruction with an IMAP propeller flap in the Toulouse University Hospital's plastic surgery department from January 2019 to December 2022. The data were collected on patient data, skin defects, and flap characteristics. RESULTS: Twenty-three IMAP flaps were realized to cover locoregional defects. The skin paddle size of the IMAP flap averaged 15.6cm long (12-20)×6.7cm wide (4-10). The average arc of rotation of the flap was 113.5° (range 70-140°). In 3 cases, the IMAP flap was performed with a superior epigastric artery perforator flap (SEAP). In 3 cases out of 23, the flap partially necrotized, requiring surgical revision. In 1 case, the flap was fully necrotized and had to be removed. DISCUSSION AND CONCLUSION: Our series of 23 IMAP flaps on thoracic reconstruction is one of the largest published to date. Our series shows that the IMAP flap offers a simple and reliable solution with minor donor site morbidity for reconstructing small to medium-sized defects in the medial and paramedian regions of the chest wall.

Background The deep inferior epigastric perforator (DIEP) and latissimus dorsi (LD) flaps are two widely used autologous breast reconstructions. Despite studies on flap-volume changes, the time of the first measurement is not immediately after surgery. Therefore, this study aimed to investigate the change in volume over time from the immediate postoperative period using a three-dimensional (3D) scanner. Methods Patients who underwent breast reconstruction with a DIEP or LD flap between October 2019 and December 2020 at Showa University Koto Toyosu Hospital were included. The Kinect 3D scanner was used to measure the reconstructed and healthy breast volumes immediately after surgery and at 1, 3, 6, and 12 months. The control group was the healthy side, and the volumes obtained at each time point and ratios (to the immediate postoperative period) were calculated and analyzed using a linear mixed model. Results Of the 25 patients and 26 breasts examined, the postoperative increase in volume ratios was statistically significant in the DIEP flap group, except for the sixth month, but decreased significantly in the LD group. Compared with the control group, the volume ratio was significantly higher up to 3 months in the DIEP flap group and decreased significantly after 3 months in the LD flap group. Conclusions The volume of the LD flap continued to decrease immediately after surgery, whereas the volume of the DIEP flap increased by 10% up to 1M. Therefore, this increase in volume should be taken into consideration in studies where the initial measurements were not taken immediately after surgery.
RESUMO
Introduction Breast reconstruction has become integral part of breast cancer treatment. Deep inferior epigastric perforator (DIEP)-based flap is considered the gold standard in autologous breast reconstruction. Aims and Objectives The aim of this study was to evaluate the patient satisfaction and the incidence of complications in DIEP flaps in an Indian setup for breast reconstruction. Materials and Methods This is a prospective, nonrandomized study at a single institute-Manipal Hospitals, Old Airport Road, Bangalore. Eligible patients were women aged between 28 and 60 years with primary breast cancer requiring mastectomy and radiotherapy, who consented for DIEP flap reconstruction. Results The study includes subjects who had autologous breast reconstruction after mastectomy with DIEP flap between January 2019 and August 2021 that included 31 patients with a minimum follow-up of 2 years. Four flaps were turbocharged and 17 flaps were superdrained primarily. The average operative time for the whole procedure by adopting a two-team approach is 353.8 ± 43.793 minutes. About 94.1% patients had excellent aesthetic score results. Six patients developed mastectomy flap necrosis, one had fat necrosis that was managed conservatively, whereas one patient had donor site re-exploration for hematoma. We had no DIEP flap necrosis, seroma, flap site hematoma, or flap failure. Physical well-being module of Breast-Q indicated an average of 83 points, psychosocial well-being module indicated 80 points, whereas sexual scores reverted an average of 77 points. Among satisfaction module, aesthetic outcomes for breast showed an average of 94 points, whereas the donor site had 96 points. Satisfaction with information, surgeon, medical staff each gained more than 87 points. Conclusion Breast reconstruction with DIEP flap yields good aesthetic outcomes and quality of life in Indian population. The incidence of fat necrosis, flap and donor site complications is less over time and will enhance the patient satisfaction score further.
RESUMO
BACKGROUND: Extensive loss of soft tissue and bone due to neoplasia, trauma, or infection in extremities often leads to amputation. CASE PRESENTATION: We present the case of a 72-year-old female patient presenting with an extended cutaneous squamous cell carcinoma of the lower leg, developed on top of necrobiosis lipoidica. After achieving the R0 resection, a 26 × 20-cm soft tissue and 15-cm tibial bone defect resulted. The contralateral leg had been lost due to the same disease 18 years before. We achieved a successful reconstruction of the leg using a pedicled fibula transplantation, an extended anterolateral thigh perforator flap, and an internal fixation with plate and screws. Two years after the original surgery, the patient is relapse-free and mobile, with adequate function of the reconstructed foot. CONCLUSIONS: Our case presented a unique combination of pedicled fibula transplantation and free extended ALT perforator flap to reconstruct an extensive defect after resection of a rare cSCC on top of NL. In selected cases, the boundaries of limb salvage can be pushed far beyond the current standards of treatment.
