Superthin Thoracodorsal Artery Perforator Flap for the Reconstruction of Palmar Burn Contracture.

ABSTRACT: Treating burn scar contractures is challenging. Although free flap transfer is an effective tool for hand reconstruction, free flaps are often bulky, causing functional disturbance and poor cosmetic appearance. Secondary debulking operations are required, resulting in a prolonged total treatment period and delayed return to daily life and work for the patient. Therefore, 1-stage reconstruction using a thin and pliable flap is ideal. In this report, we present the superthin TDAP flap as an option for the reconstruction of postburn palmar contracture. During TDAP flap elevation, the thoracodorsal artery perforator was identified and traced distally until its penetration into the dermis. Subsequently, the subdermal tissue was removed and a uniformly superthin TDAP flap was elevated. Postoperatively, early functional recovery was achieved with excellent palmar contour and texture. No revision surgery was required and no recurrence of contractures occurred during the 6-month follow-up. This procedure is useful in elevating a superthin TDAP flap and is a feasible option for the reconstruction of working surfaces, such as the palm.

Effective Secondary Reconstruction of Refractory Urethrocutaneous Fistula after Metoidioplasty Using Folded Superficial Circumflex Iliac Artery Perforator Flap.

Project description:One of the primary goals of penile reconstruction for female-to-male transsexuals is to enable voiding while standing. Metoidioplasty represents a viable option, but it is associated with a high rate of postoperative fistula formation and recurrence, which affects the aesthetic and functional outcomes. Subsequent surgical repair using scarred and inadequate local tissue may contribute to fistula recurrence. The folded superficial circumflex iliac artery perforator (SCIP) island flap offers sufficient well-vascularized tissue and skin envelope for the reconstruction of the urethra and outer skin after failed metoidioplasty. The SCIP flap can be elevated as a hairless thin flap, making it useful in urethral reconstruction even when it is folded. We describe a case of a 44-year-old female-to-male transsexual patient who developed a refractory urethrocutaneous fistula after metoidioplasty. Surgical repairs were attempted using local tissue 4 times without success. The patient presented to our hospital, and we performed urethral reconstruction using a folded, pedicled SCIP flap for both urethra and skin augmentation. The postoperative course was uneventful, with satisfactory functional results and low donor-site morbidity. No fistula recurrence was observed during the 2 years of follow-up. This novel procedure offers a viable alternative technique for refractory urethrocutaneous fistula repair.

An Innovative Autologous Breast Reconstruction Option: Musculo-derma-glandular, Axio-perforator, Bipedicled Flap.

Project description:Following a mastectomy, patients frequently seek breast reconstruction. Although there are several options for reconstruction, none of them are considered ideal. Taking patients' psychological and physical condition into account, we created a new flap technique with a low postoperative morbidity and short operation time. We harvested the flap composed of skin, breast tissue, and pectoralis major muscle with a base in the parasternal line from the contralateral breast. To display our results, we presented 2 case examples. The mean follow-up was 12 months, and no postoperative complications were observed. At follow-ups, patients answered the question, "How satisfied are you with the results of the surgery?" using a 5-point Likert-like scale (5, very satisfied; 4, somewhat satisfied; 3, undecided; 2, somewhat dissatisfied; and 1, very dissatisfied). The mean score was 4. Our study showed that this surgical approach is a safe and cost-effective alternative for immediate and delayed breast reconstruction.

Predictors of Reoperations in Deep Inferior Epigastric Perforator Flap Breast Reconstruction.

Project description:The deep inferior epigastric perforator (DIEP) procedure is regarded a safe option for autologous breast reconstruction. Reoperations, however, may occur, and there is no consensus in the literature regarding the risk factors. The aim of this study was to identify factors associated with reoperations in DIEP procedure.A retrospective study of consecutive patients undergoing DIEP breast reconstruction 2007 to 2014 was performed and included a review of 433 medical charts. Surgical outcome was defined as any unanticipated reoperation requiring return to the operating room. Multivariate regression analysis was utilized to identify predictors of reoperation. The following factors were considered: age, body mass index, comorbidity, childbearing history, previous abdominal surgery, adjuvant therapy, reconstruction laterality and timing, flap and perforator characteristics, and number and size of veins.In total, 503 free flaps were performed in 433 patients, 363 (83.8%) unilateral and 70 (16.2%) bilateral procedures. Mean age was 51 years; 15.0% were obese; 13.4% had hypertension; 2.3% had diabetes; 42.6% received tamoxifen; 58.8% had preoperative radiotherapy; 45.6% had abdominal scars. Reoperation rate was 15.9% (80/503) and included flap failure, 2.0%; partial flap loss, 1.2%; arterial thrombosis, 2.0%; venous thrombosis, 0.8%; venous congestion, 1.2%; vein kinking, 0.6%. Other complications included bleeding, 2.2%; hematoma, 3.0%; fat necrosis, 2.8%, and infection, 0.2%. Factors negatively associated with reoperation were childbearing history (odds ratio [OR]: 3.18, P = 0.001) and dual venous drainage (OR: 1.91, P = 0.016); however, only childbearing remained significant in the multivariate analyses (OR: 4.56, P = 0.023).The history of childbearing was found to be protective against reoperation. Number of venous anastomoses may also affect reoperation incidence, and dual venous drainage could be beneficial in nulliparous patients.

Complications following immediate compared to delayed deep inferior epigastric artery perforator flap breast reconstructions.

Project description:PURPOSE:As more breast cancer patients opt for immediate breast reconstruction, the incidence of complications should be evaluated. The aim of this study was to analyze the recipient-site complications and flap re-explorations of immediate compared to delayed deep inferior epigastric artery perforator (DIEP) flap breast reconstructions. METHODS:For this multicenter retrospective cohort study, the medical records of all patients who underwent DIEP flap breast reconstruction in three hospitals in the Netherlands between January 2010 and June 2017 were reviewed. Patient demographics, risk factors, timing of reconstruction, recipient-site complications, and flap re-explorations were recorded. RESULTS:A total of 910 DIEP flap breast reconstructions (n = 397 immediate and n = 513 delayed reconstructions) in 737 patients were included. There were no significant differences in major complications or flap re-explorations between immediate and delayed reconstructions. The total flap failure rate was 1.5 and 2.5% in the immediate and delayed group, respectively. Significantly more hematomas (OR 2.91; 95% CI 1.59-5.30; p = 0.001) and seromas (OR 3.60; 95% CI 1.14-11.4; p = 0.029) occurred in immediate reconstructions, whereas wound problems were more frequently observed in delayed reconstructions (OR 1.99; 95% CI 1.27-3.11; p = 0.003). Correction for potential confounders still showed significant differences for hematoma and seroma, but no longer for wound problems (p = 0.052). CONCLUSIONS:This study demonstrated similar incidences of major recipient-site complications and flap re-explorations between immediate and delayed DIEP flap breast reconstructions. However, hematoma and seroma occurred significantly more often in immediate reconstructions, while wound problems were more frequently observed in delayed reconstructions.

Superficial Circumflex Iliac Perforator-Osteocutaneous Flap for Reconstruction of Extensive Composite Defects in the Forefoot.

Project description:Although the great toe plays important roles in walking, loading, and maintaining balance when compared with other toes, there are few reports on great toe reconstruction, including the reconstruction of distal phalanx. This report aims to describe the use of a superficial circumflex iliac artery perforator (SCIP)-osteocutaneous flap for reconstructing a complex tissue defect of the great toe. A 62-year-old man presented with a crush injury to the forefoot. Because the great toe was severely crushed, the defect distal to the proximal phalanx of the great toe was reconstructed using a SCIP-osteocutaneous flap. The immediate postoperative course was uneventful; however, surgical revision was necessary. Signs of osseous union could be observed on radiographic images taken 2 months after the initial surgery. Twenty-four months after surgery, the patient could freely walk without resorption of the transferred bone. We demonstrated that SCIP-osteocutaneous flaps may be promising free flaps in complex tissue defect reconstruction of the great toe.

A case of an upper anterior abdominal wall extra-skeletal Ewing sarcoma- soft tissue reconstruction with medial intercostal artery perforator flap and free anterolateral thigh fasciocutaneous flap with arteriovenous loop graft.

Project description:IntroductionExtra-skeletal Ewing sarcoma - a rare clinical entity. After the tumour resection, a huge upper anterior abdominal wall defect poses a challenge in soft tissue reconstruction in a thin individual.Case presentationWe report an anterior abdominal wall Ewing sarcoma in a 22-year-old gentleman, arising from the left rectus abdominis muscle. After wide local excision, the reconstruction was achieved with free anterolateral thigh(ALT) fasciocutaneous flap with arteriovenous(AV) loop graft, right medial intercostal artery perforator(MICAP) flap and split-thickness skin graft(SSG).DiscussionThe goals of anterior abdominal wall reconstruction are to restore the integrity of the abdominal wall, prevent visceral eventration, and provide functional support. In view of the size of the defect, a free ALT flap was harvested and anastomosed to the left deep inferior epigastric bundle with the AV loop graft. Although the current trend is skewed towards the use of biologic mesh, an on-lay prolene mesh was used due to its affordable cost and that the biologic mesh was not available in Malaysia. The options of further reconstruction after the patient developed marginal flap necrosis and surgical site infection were also discussed. Post-operation 3 months, there was denser hair growth on the ALT flap. This finding has never been reported before and warrants further studies.ConclusionThe use of combination of various technique, namely free ALT fasciocutaneous flap with AV loop graft, right MICAP flap and SSG in reconstruction ensures a satisfactory functional and aesthetic outcome in the upper anterior abdominal wall reconstruction.

Customized reconstruction of a complex soft-tissue defect around the knee with a free perforator flap.

Project description:Reconstruction of a complex defect around the knee, particularly involving a large soft-tissue defect or disruption of the extensor mechanism, is always a challenging problem. The purpose of this study was to introduce the use of a customized free perforator flap for complex soft-tissue reconstruction around the knee. Between June 2010 and March 2017, 16 patients underwent this procedure. The choice of flap design is based on the location of the wound, the required pedicle length, the missing tissue components and their volumes, and the risk of donor-site morbidity. The reconstruction was performed using anterolateral thigh perforator (ALTP) flaps in five cases, modified ALTP flaps in two cases, chimeric ALTP flaps in four cases, dual-skin paddle ALTP flaps in two cases, and chimeric thoracodorsal artery perforator flaps in two cases. Multiple perforator flaps and vascularized fascia lata were used in one case. All flaps survived postoperatively. No vascular congestion was observed, and partial necrosis was observed in only one case. Primary closure of the donor site was performed for all patients. At a mean follow-up time of 16.5 months, most cases showed satisfactory flap contours and acceptable functional outcomes. A free perforator flap is a reliable option for repairing complex soft-tissue defects in the knee region, especially when local and pedicled flaps are unavailable. Various flap designs allow for more individualized treatment approaches and can achieve better results.

The Dorsoulnar Artery Perforator Adipofascial Flap in the Treatment of Distal Radioulnar Synostosis.

Project description:Posttraumatic radioulnar synostosis (RUS) is a rare event following forearm fractures. Consequences are disabling for patients who suffer from functional limitation in forearm pronosupination. Distal RUS are even more rare and more difficult to treat because of high recurrence rates. The patient we describe in this paper came to our attention with a double distal RUS recurrence and a Darrach procedure already performed. We performed a radical excision of RUS and interposition with a vascularized dorsoulnar artery (DUA) adipofascial perforator flap. Four years after surgery, the patient shows the same complete range of motion in pronosupination, and MRI confirms that the flap is still in place with signs of vascularization. Simple synostosis excision has been proven ineffective in many cases. Interposition is recommended after excision, and biological material interposition seems to be more effective than foreign material. Surgeons are increasingly performing vascularized interposition, and the results are very encouraging.

The Modified Crescenteric Anterior Intercostal Perforator Flap.

Project description:Lower pole breast cancers are challenging to manage because conventional wide local excision may produce a "bird's beak" deformity. In an era of oncoplastic surgery, techniques that balance oncological results with cosmetic outcomes such as local flaps have extended the role of breast-conserving surgery. Local flaps are particularly useful for partial breast reconstruction due to the relative simplicity of the surgical procedure and reduced morbidity. Intercostal artery perforator flaps have a shorter duration of surgery than free flaps and do not require microsurgical anastomoses. Anterior intercostal artery perforator (AICAP) flaps provide excellent cosmesis, yet traditional crescenteric harvest yields limited volume for reconstruction. We describe a modification to an established reconstructive technique for lower pole breast defects. The technique is based on 3 extensions of tissue, providing a larger volume of tissue replacement compared with traditional AICAP flaps. The technique is particularly suitable for small- and medium-sized non-ptotic breasts, with lower pole tumors. The modified crescenteric AICAP technique can be used to increase the available tissue when performing lower pole reconstructions.
