Lotus petal flap for unusual indication: A recto-vaginal fistula with perineal defect after vaginal delivery

Introduction and importanceThree to five percent of vaginal deliveries are complicated by third or fourth degree perineal laceration. Misdiagnosed perineal injuries may be associated with a poor sexual and psychological prognosis. Management of old perineal tears and laceration is challenging with a high failure rate. In such condition, interposition tissue technic or local flap can be a good surgical alternative. Lotus petal Flap, usually indicated in management of large perineal defect in gynecological oncology can be used.Case presentationWe report a case of 32-year-old women presenting complex and relapsed perineal fistula after vaginal delivery associated with perineal defect treated by lotus petal flap with a good outcome.DiscussionPerineal defects are commonly encountered after oncologic, traumatic or infectious perineal excisions and described as a challenging situation. In case of perineal defects after obstetrical tears, no validated surgical filler technics are recommended. Inspired from oncologic surgical technics to fill perineal defects, Lotus Flap can be used. Its advantages are to mobilize a satisfactory tissue volume to fill important perineal defect compared to the small bulbocavernous flap with a hidden scar comparing to gracilis muscle flap. This technic is associated with a good sexual and self-imaging outcome.ConclusionLotus petal flap may be required as a solution to manage perineal defect in case of perineal fistula. This technique provides aesthetic and good results for perineal reconstruction.     

A safe and simple technique using the distal pedicled reversed upper arm flap to cover large elbow defects.

The reconstruction of large soft-tissue defects at the elbow is hard to achieve by conventional techniques and is complicated by the difficulty of transferring sufficient tissue with adequate elasticity and sensate skin. Surgical treatment should permit early mobilisation to avoid permanent functional impairment. Clinical experience with the distal pedicled reversed upper arm flap in 10 patients suffering from large elbow defects is presented (seven male, three female; age 40-70 years). The patient sample included six patients with chronic ulcer, two with tissue defects due to excision of a histiocytoma, and one patient with burn contracture. In the two cases of histiocytoma, defect closure of the elbow's ulnar area was achieved by using a recurrent medial upper arm flap. In the eight other patients we used a flap from the lateral upper arm with a flap rotation of 180 degrees. Average wound size ranged from 4 to 10 cm, average wound area from 30 to 80 cm(2). Flap dimensions ranged from 15 x 8 cm for the lateral upper arm flap to 29 x 8 cm for the medial upper arm flap. The inferior posterior radial and ulnar collateral arteries are the major nutrient vessels of the reversed lateral and medial upper arm flaps. Perforating vessels are identified preoperatively using colour Doppler ultrasonography. Flap failure did not occur. Secondary wound closure became necessary due to initial wound healing difficulties in one patient. Mean operation time was 1.5 h and mean follow-up period 12 months. Good defect coverage with tension-free wound closure was achieved in all cases. Stable defect coverage led to long-term wound stability without any restriction of elbow movement. The lateral and medial upper arm flaps represent a safe and reliable surgical treatment option for large elbow defects. The surgical technique is comparatively simple and quick.     

Freestyle propeller flaps to reconstruct defects of the posterior trunk: a simple approach to a difficult problem

The reconstruction of complex defects of the back remains difficult. However, a local skin flap alone based on a competent single perforator can have a large skin territory with an efficient arc of rotation as a propeller flap to cover many back wounds, while the donor site can still be closed primarily. Eleven patients with defect sizes ranging from 36 to 264 cm(2) underwent coverage of posterior trunk defects using propeller flap (rotated perforator flaps), and all the donor sites were primarily closed. The average number of perforators within the flap was 1.4. All flaps healed uneventfully except for 1 case in which congestion was noted; leech was applied and the flap healed well. Radiation therapy was done in 1 case and was uneventful. The freestyle perforator propeller flap can be a reliable and a simpler solution to reconstruct a difficult defect while achieving minimal donor site morbidity.     

Reconstruction of the external genitals and repair of skin defects of the perineal region using three types of lateral groin flap

Three types of lateral groin flap have been applied to reconstruct the external genitals and to repair skin defects in the perineal region. A single lateral groin flap was used to construct a vagina for 2 patients who had congenital absence of vagina. A composite flap containing iliac crest bone was applied to reconstruct the penis in 11 patients: 8 suffered traumatic amputation and 3 had congenital micropenis. A coaxial pedicle flap of the lateral groin and abdominal area was used to repair skin defects of the penis and scrotum after resection of the elephantiasis caused by recurrent erysipelas in 2 patients, and to relieve postburn scar contracture in the perineal region in another. Using this operative technique, 14 flaps survived completely with satisfactory results; 70% of one composite flap was lost as a result of hematoma. In the single-flap group, the distal portion (3 x 5 cm) of one flap necrosed and was resected and resurfaced with a free skin graft; the final result was good.

Reverse first dorsal metatarsal artery flap for reconstruction of traumatic defects of dorsal great toe

BACKGROUND: Soft-tissue defects of the great toe that include exposed tendon and bone present a reconstructive challenge for plastic surgeons. This study investigates the feasibility and reliability of reverse first dorsal metatarsal artery flap (FDMA) for reconstruction of the dorsal great toe soft-tissue defects. METHODS: Six male patients with dorsal great toe defects (mean 2.2 x 4.7 cm) underwent reconstruction using the reverse FDMA flap. Preoperative angiography was performed to confirm the existence and patency of the distal communicating artery between the FDMA and plantar metatarsal artery. The flap was raised by dividing the dorsalis pedis artery and proximal communicating arteries and rotated 180 degrees to cover the defect. RESULTS: All flaps survived completely. Mean follow-up time was 3.3 months. Painless full range of motion was recovered and the contour of the flap was satisfactory. All patients returned to their normal walking and running activities and none necessitated special footwear. No donor-site morbidity was encountered. CONCLUSION: Reverse FDMA flap presents a viable alternative for reconstruction of soft-tissue defects of dorsal great toe when local flap coverage is required. Because of anatomic variations, preoperative angiography is necessary for successful reconstruction, especially in patients with comorbidities affecting patency of their vasculature.     

Die Deckung von Weichteildefekten und instabilen Narben über der Achillessehne durch freie mikrochirurgische Lappenplastiken

INTRODUCTION: Coverage of the exposed Achilles tendon requires thin, supple tissue to provide adequate range of motion and a satisfying aesthetic result for the distal lower extremity. Various local flaps and free flaps have been described for reconstruction of small and large defects. Small defects can be closed with local tissue, whereas free flap coverage may be necessary for coverage of large defects. METHODS: From July 1993 to September 1998 14 patients between the age of 15 and 74 years (mean 47 years; 3 female, 11 male) underwent free flap coverage for the exposed Achilles tendon due to primary trauma, chronic wounds or tumors. The mean duration of follow-up was 33.3 months. The defect size ranged from 8 x 8 to 25 x 28 cm. RESULTS: Six parascapular flaps (three with a vascularized scapular fascial extension), four radial forearm flaps and four latissimus dorsi flaps (one combined with free serratus fascia) were used for soft tissue coverage over the Achilles tendon. Thirteen flaps survived. In one case a parascapular flap had to be removed due to venous thrombosis and a free latissimus dorsi flap was used as secondary salvage procedure. The donor site morbidity was acceptable for most patients after flap harvesting in the subscapular region and also satisfactory in the forearm region. Average active range of motion in the upper ankle joint was 15-0-40 degrees for extension/flexion. All patients were satisfied with the functional and aesthetic result. CONCLUSION: Soft tissue coverage over the exposed Achilles tendon requires an optimal solution for each patient to achieve an aesthetically pleasing result and acceptable function. Microvascular free flaps can be used to reconstruct medium and large defects and to provide gliding tissue for the Achilles tendon. The complication rate of microvascular flaps is comparable with that of local flaps.

Reconstruction of a large pelvic defect by transfer of a quadruplet combination of pedicled flaps from the medial thigh using bilateral muscular gracilis flaps and bilateral vertical posteromedial thigh (vPMT) propeller flaps—A case report

The reconstruction of defects of the perianal area and vagina places a high demand on a reconstructive surgeon. Different reconstructive methods include a skin graft, a local skin flap, a musculocutaneous flap, and a pedicled perforator flap. Here, we report the case of a 59-year-old female patient with a pelvic defect, who underwent reconstruction with a quadruplet combination of pedicled flaps from the medial thigh, due to an extensive resection of a recurrence of a squamous cell carcinoma of the anus, vulva, and partially the colon. The surgical oncologist performed a rectum amputation, a partial colectomy, a complete hysterectomy, and a resection of the dorso-lateral vaginal vault in order to achieve tumor-free margins. The resulting defect measured 14 × 11 cm² with 8 cm of deep space. The defect was covered and reconstructed by employing a bilateral pedicled gracilis muscle flap rotated about 120° and advanced to fill up the residual spare space in the deep and a bilateral vertical posteromedial thigh (vPMT) using a propeller flap measuring 27 × 10 cm² rotated 180° in order to reconstruct the vagina and the perianal area. All flaps survived without major post-operative complications. The donor site morbidity was minimal. The range of motion was not limited over both hip and knee joints. Patient had no problem with urination. Sexual intercourse was not highly considered due to patient's old age. The follow-up at 6 months showed acceptable cosmetic results with a satisfying contour of the coverage and reconstructed area. The combination of pedicled gracilis muscle flap and vPMT propeller flap may represent a valuable option in such a defect where deep space obliteration and reconstruction of the vagina with perianal contouring are needed.     

The horn shaped fascio-cutaneous flap usage in cutaneous malignancy of the leg.

The cover of defects in the leg is a surgical challenge, especially in the elderly patient. We report our experience in 24 patients, who underwent excision of a cutaneous malignancy and subsequent cover of the defect with a horn shaped fascio-cutaneous flap. The patients' average age was 77 with a range of 61-89 years. The average size of the defect covered was 4x4 cm, with a range from 3x3 to 8x8 cm. There were no flap losses. Two complications presented following discharge from hospital, one required further surgery. These findings indicate that this technically simple flap is reliable, with a low complication rate (8%), and produces an aesthetic result. It provides an alternative to split skin grafting for cutaneous malignancy defects of the leg.     

Free medialis pedis flap as a coverage and flow-through flap in hand and digit reconstruction.

BACKGROUND: Skin and soft-tissue defects of the hand and digit present a challenge for the hand surgeon especially in meeting the reconstructive needs of thickness, texture, color matching, and sensation. It becomes an even bigger challenge to reconstruct the defect in a devascularized finger with segmental loss of the neurovascular bundle. We use the relatively new flap, the medialis pedis flap, to solve the above conditions and compare it with traditional flaps. METHODS: From May of 1994 to March of 1997, the free medialis pedis flap was used to reconstruct 19 digit and hand defects; the flap sizes ranging from 1.5 x 3.0 cm to 3.0 x 9.0 cm. Sixteen flaps were used for simple coverage of digit defects, including 12 for single-digit and 4 for multiple-digit reconstruction. The remaining three flaps were used as coverage and a flow-through flap for devascularized fingers. RESULTS: All 19 flaps survived and achieved a good protective sensation. The appearance was very satisfactory, and the donor-site scars were without sensory problems. CONCLUSION: Compared with traditional flaps, the free medialis pedis has the following advantages: it provides good thickness, texture, and color matching for hand and digit resurfacing; it can be used as a flow-through flap and as coverage for a devascularized finger in a one-stage procedure; the size of the feeding vessels of the flap matches those of the digital vessels well; and it consists of glabrous skin rich in nerve endings, so it has good potential for sensory recovery. Because of all of these characteristics, the free medialis flap may become a better consideration for hand surgeons.     

Secret scar free gracilis flap

The gracilis free flap is a workhorse in plastic surgery. We present a modified technique that relies on a single horizontal thigh-lift-type approach, which (1) gives wide pedicle exposure, (2) provides material for skin grafting, and (3) allows for distal flap transection without an additional incision. Eighteen gracilis free flaps were performed from 2007 to 2009 for lower extremity reconstruction. Complete flap survival was observed in 17 patients with one partial necrosis distally. Our approach allowed access to divide the distal gracilis tendon without a second incision in all cases. The mean scar length was 16 ± 3 cm and no hypertrophic scars were observed. In 15 patients, no visible scar was observed in the upright position, and in three patients, the scar was visible dorsally (2 ± 1 cm). No sensory deficits were observed 6 months postoperatively. In addition, the split-thickness skin graft harvested from the skin paddle was sufficient to cover all defects.

A free microsurgical transfer of a radial (Chinese) flap in reconstructing the lower limb

The microsurgical transplantation of the radial flap to the hind limb has as main advantages to offer a good quality and sensitive skin cover, the possibility to use the flap's radial artery as a vascular bypass and to raise composite flaps with tendon or bone in case of complex reconstruction. MATERIAL AND METHODS: The authors present 9 free radial flap transfers to the foot. Patients' ages ranged from 22 to 50 years. Flap dimensions varied between 7 x 5 cm and 12 x 9 cm. Two flaps contained the flexor carpi radialis tendon to reconstruct the Achilles' tendon and one flap included a bone graft from the radial shaft to resolve a bone defect in the second metatarsal. All flaps were reinnervated by suturing the antebrachial cutaneous nerve of the flap to a cutaneous nerve in the recipient site. RESULTS: There was only one failure in an extensive crush injury. We recommend the radial flap in reconstructing complex defects for it's versatility and for the fact that it can include all types of tissue that may be necessary.

Distally based dorsal pedal neurocutaneous flap for forefoot coverage

The authors describe their experience with the use of the distally based dorsal pedal neurocutaneous flap for distal foot coverage. Ten patients underwent reconstruction with 13 flaps between 2004 and 2008. One patient suffered from a traffic accident and 9 from electrical injury. All of the soft tissue defects resulted in metatarsophalangeal joint and phalanx bone exposure. The size of the flaps ranged from 6 × 2 cm to 11 × 6 cm. The flaps were elevated based on intermediate or medial dorsal pedal nerves. Nine flaps were harvested in first stage to repair the distal foot. Among them, 3 showed partial necrosis in the distal region because of venous insufficiency. Four flaps underwent a surgical delay procedure in the first stage and were then transferred to reconstruct phalanx wounds in the second stage, surviving completely. All patients were satisfied with their reconstruction and donor site contour. The distally based dorsal pedal neurocutaneous flap can be used to repair the distal foot soft tissue defects, providing sufficient skin territory and excellent aesthetic and functional recovery. Surgical delay effectively enhances the distally based dorsal pedal neurocutaneous flap survival, particularly for the large size flaps.
