Lymphedema surgery: the current state of the art.

BACKGROUND/PURPOSE: Lymphedema surgery, when integrated into a comprehensive lymphedema treatment program for patients, can provide effective and long-term improvements that non-surgical management alone cannot achieve. Such a treatment program can provide significant improvement for many issues such as recurring cellulitis infections, inability to wear clothing appropriate for the rest of their body size, loss of function of arm or leg, and desire to decrease the amount of lymphedema therapy and compression garment use. METHODS: The fluid predominant portion of lymphedema may be treated effectively with surgeries that involve transplantation of lymphatic tissue, called vascularized lymph node transfer (VLNT), or involve direct connections from the lymphatic system to the veins, called lymphaticovenous anastomoses (LVA). VLNT and LVA are microsurgical procedures that can improve the patient's own physiologic drainage of the lymphatic fluid, and we have seen the complete elimination for the need of compression garments in some of our patients. These procedures tend to have better results when performed when a patient's lymphatic system has less damage. The stiff, solid-predominant swelling often found in later stages of lymphedema can be treated effectively with a surgery called suction-assisted protein lipectomy (SAPL). SAPL surgeries allow removal of lymphatic solids and fatty deposits that are otherwise poorly treated by conservative lymphedema therapy, VLNT or LVA surgeries. CONCLUSION: Overall, multiple effective surgical options for lymphedema exist. Surgical treatments should not be seen as a "quick fix", and should be pursued in the framework of continuing lymphedema therapy and treatment to optimize each patient's outcome. When performed by an experienced lymphedema surgeon as part of an integrated system with expert lymphedema therapy, safe, consistent and long-term improvements can be achieved.

Surgeon motivations behind the timing of breast reconstruction in patients requiring postmastectomy radiation therapy.

OBJECTIVES: Although postmastectomy radiation therapy (PMRT) has been shown to reduce breast cancer burden and improve survival, PMRT may negatively influence outcomes after reconstruction. The goal of this study was to compare current opinions of plastic and reconstructive surgeons (PRS) and surgical oncologists (SO) regarding the optimal timing of breast reconstruction for patients requiring PMRT. METHODS: Members of the American Society of Plastic Surgeons (ASPS), the American Society of Breast Surgeons (ASBS), and the Society of Surgical Oncology (SSO) were asked to participate in an anonymous web-based survey. Responses were solicited in accordance to the Dillman method, and they were analyzed using standard descriptive statistics. RESULTS: A total of 330 members of the ASPS and 348 members of the ASBS and SSO participated in our survey. PRS and SO differed in patient-payor mix (p < 0.01) and practice setting (p < 0.01), but they did not differ by urban versus rural setting (p = 0.65) or geographic location (p = 0.30). Although PRS favored immediate reconstruction versus SO, overall timing did not significantly differ between the two specialists (p = 0.14). The primary rationale behind delayed breast reconstruction differed significantly between PRS and SO (p < 0.01), with more PRS believing that the reconstructive outcome is significantly and adversely affected by radiation. Both PRS and SO cited "patient-driven desire to have immediate reconstruction" (p = 0.86) as the primary motivation for immediate reconstruction. CONCLUSIONS: Although the optimal timing of reconstruction is controversial between PRS and SO, our study suggests that the timing of reconstruction in PMRT patients is ultimately driven by patient preferences and the desire of PRS to optimize aesthetic outcomes.

Use of Dual, Tubularized Supraclavicular Artery Island Flaps in Series to Restore Gastrointestinal Continuity After a Failed Ileocolic Esophageal Reconstruction.

The supraclavicular artery island flap (SCAIF) is a versatile pedicled flap that can be an excellent alternative to free flap reconstruction in complex head and neck defects. We use the SCAIF routinely as a first-line option for many of our soft tissue head and neck reconstructions. Here we describe a novel application of dual SCAIFs used in series for proximal esophageal reconstruction. This followed esophagectomy for neoplastic disease and failed gastric pull-up and colonic interposition procedures.

A novel two-stage surgical approach to treat chronic lymphedema.

Surgical treatment of chronic lymphedema has seen significant advances. Suction-assisted protein lipectomy (SAPL) has been shown to safely and effectively reduce the solid component of swelling in chronic lymphedema. However, these patients must continuously use compression garments to control and prevent recurrence. Microsurgery procedures, including lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), have been shown to be effective in the management of the fluid component of lymphedema and allow for decreased garment use. SAPL and VLNT were applied together in a two-stage approach in two patients with chronic lymphedema after treatment for breast cancer. SAPL was used first to remove the chronic, solid component of the soft-tissue excess. Volume excess in our patients' arms was reduced an average of approximately 83% and 110% after SAPL surgery. After the arms had sufficiently healed and the volume reductions had stabilized, VLNT was performed to reduce the need for continuous compression and reduce fluid re-accumulation. Following the VLNT procedures, the patients were able to remove their compression garments consistently during the day and still maintain their volume reductions. Neither patient had any postoperative episodes of cellulitis. SAPL and VLNT can be combined to achieve optimal outcomes in patients with chronic lymphedema.

Review of current surgical treatments for lymphedema.

BACKGROUND: The current mainstay of lymphedema therapy has been conservative nonsurgical treatment. However, surgical options for lymphedema have been reported for over a century. Early surgical procedures were often invasive and disfiguring, and they often had only limited long-term success. In contrast, contemporary surgical techniques are much less invasive and have been shown to be effective in reducing excess limb volume, the risk of cellulitis, and the need for compression garment use and lymphedema therapy. Microsurgical procedures such as lymphaticovenous anastomosis and vascularized lymph node transfer lymphaticolymphatic bypass can treat the excess fluid component of lymphedema swelling that presents as pitting edema. Suction-assisted protein lipectomy is a minimally invasive procedure that addresses the solid component of lymphedema swelling that typically occurs later in the disease process and presents as chronic nonpitting lymphedema. These surgical techniques are becoming increasingly popular and their success continues to be documented in the medical literature. We review the efficacy and limitations of these contemporary surgical procedures for lymphedema. METHODS: A Medline literature review was performed of lymphedema surgery, vascularized lymph node transfer, lymphaticovenous anastomosis, lymphatic liposuction, and lymphaticolymphatic bypass with particular emphasis on developments within the past 10 years. A literature review of technique, indications, and outcomes of the surgical treatments for lymphedema was undertaken. RESULTS: Surgical treatments have evolved to become less invasive and more effective. CONCLUSIONS: With proper diagnosis and the appropriate selection of procedure, surgical techniques can be used to treat lymphedema safely and effectively in many patients when combined with integrated lymphedema therapy.

An effective system of surgical treatment of lymphedema.

BACKGROUND: Effective surgical treatments for lymphedema now can address the fluid and solid phases of the disease process. Microsurgical procedures, including lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), target the fluid component that predominates at earlier stages of the disease. Suction-assisted protein lipectomy (SAPL) addresses the solid component that typically presents later as chronic, nonpitting lymphedema of an extremity. We assess the outcomes of patients who underwent selective application of these three surgical procedures as part of an effective system to treat lymphedema. METHODS: This is a retrospective chart review of patients with lymphedema who underwent complete decongestive therapy followed by surgical treatment with SAPL, LVA, or VLNT. The primary outcomes measured were postoperative volume reduction (SAPL), daily requirement for compression garments and lymphedema therapy (VLNT and LVA), and the incidence of severe cellulitis. RESULTS: Twenty-six patients were included in the study, of which 10 underwent SAPL and 16 underwent LVA or VLNT. The average reduction of excess volume by SAPL was 3,212 mL in legs and 943 mL in arms, or a volume reduction of 87 and 111 %, respectively, when compared with the unaffected, opposite sides. Microsurgical procedures (VLNT and LVA) significantly reduced the need for both compression garment use (p = 0.003) and lymphedema therapy (p < 0.0001). The overall rate of cellulitis decreased from 58 % before surgery to 15 % after surgery (p < 0.0001). CONCLUSIONS: When applied appropriately to properly selected patients, surgical procedures used in the treatment of lymphedema are effective and safe.

The sensate fibula osteocutaneous flap: neurosomal anatomy.

BACKGROUND: Rapid return of oral sensation enhances quality of life following oromandibular reconstruction. For predictable reinnervation of flaps, a detailed knowledge of their nerve supply is required. This study was designed to investigate the cutaneous nerve supply of the fibula osteocutaneous flap. METHODS: We dissected thirty-seven fresh cadaveric specimens to better understand the cutaneous innervation of the typical fibula flap that would be used in oromandibular reconstruction. In addition, ten volunteers were enlisted for nerve blocks testing the cutaneous innervation of the lateral aspect of the lower leg. RESULTS: The lateral sural cutaneous nerve (LSCN) is generally considered to be sole cutaneous innervation to the lateral aspect of the lower leg; however, our analysis of the cadaveric specimens revealed dual innervation to this region. We identified a previously unnamed distal branch of the superficial peroneal nerve, which we have termed the recurrent superficial peroneal nerve (RSPN). Given the cadaveric findings, both the LSCN and the RSPN were tested using sequential nerve blocks in 10 volunteers. An overlapping pattern of innervation was demonstrated. CONCLUSIONS: The lateral aspect of the lower leg has an overlapping innervation from the LSCN and the newly described RSPN. The overlap zone lies in the region of the skin paddle of the fibula flap. The exact position of the neurosomal overlap zone (N.O.Z.E.) may be an important factor in reestablishing sensation in the fibula's skin paddle following free tissue transfer.

The sensate fibular osteoneurocutaneous flap in oromandibular reconstruction: clinical outcomes in 31 cases.

Thirty-one patients requiring composite mandibular resection were reconstructed with sensate fibula osteocutaneous flaps. Preoperatively, all patients underwent lower extremity sensory testing at the location of the proposed flap site. Intraoperatively, either the Lateral Sural Cutaneous Nerve (LSCN) or the Recurrent Superficial Peroneal Nerve (RSPN) was chosen as donor. It was then joined to either the lingual or the greater auricular nerve. Both end-to-end and end-to-side neurorrhaphies were used. At least six months postoperatively, the intraoral flaps were tested for sensory function. Twenty-eight patients achieved sensory return, including hot/cold and pinprick sensation. Both the LSCN and RSPN groups demonstrated improved two-point discrimination in static and moving studies. Better results were obtained when the lingual rather than the greater auricular nerve was the recipient. Only three patients underwent end-to-side repair, with improved two-point discrimination in two patients. The average follow-up for all patients was 11.7 months. The most dramatic return of sensory function was seen in the end-to-end lingual nerve neurorrhaphies, followed by end-to-side lingual nerve neurorrhaphies. Of the five repairs using the greater auricular nerve, only three demonstrated any measurable postoperative sensory return. Functional outcomes of postoperative patients were measured via analysis of speech, type of food consumption, and oral continence. The majority of patients exhibited normal or easily intelligible speech, was able to consume a soft food or normal diet, and could maintain normal to manageable oral continence. A subset of patients enrolled in the study went on to pursue dental rehabilitation.

Bipedicled flaps in posttraumatic lower-extremity reconstruction.

BACKGROUND: Complex, lower-extremity, soft-tissue defects pose a significant challenge to the reconstructive surgeon and often require the use of free flaps, which puts significant demands on the patient, the surgeon and the health-care system. Bipedicled flaps are random but receive a blood supply from two pedicles, allowing the surgeon to use local tissue with an augmented nutrient blood flow. They are simple to elevate and economical in operating time. This study describes our experience with lower-extremity wound reconstruction using the bipedicled flap as an alternative to pedicled flaps and free flaps. METHODS: Ten patients with lower-extremity defects underwent bipedicled flap reconstruction. Operative times, length of stay following flap procedure and postoperative complications were documented. Data were collected in a prospective fashion. RESULTS: Two patients had minimal areas of flap necrosis, both of which resolved with conservative local wound care and one patient developed a postoperative wound infection remedied with a course of oral antibiotics. We experienced one major complication involving wound dehiscence requiring an additional flap. CONCLUSIONS: Bipedicled flaps provide a safe, fast and relatively easy alternative for coverage of certain complex open wounds in the lower extremities. Their use does not preclude the use of more traditional options of pedicled muscle or free flap coverage at a later time should they be required. CLINICAL QUESTIONS ADDRESSED/LEVEL OF EVIDENCE: What are alternative strategies for lower-extremity wound reconstruction. Level of Evidence V.

Supraclavicular artery island flap (SCAIF) vs free fasciocutaneous flaps for head and neck reconstruction.

OBJECTIVE: At our institution, the supraclavicular artery island flap (SCAIF) has become a reliable option for fasciocutaneous coverage of complex head and neck (H&N) defects. We directly compare the outcomes of reconstructions performed with SCAIFs and free fasciocutaneous flaps (FFFs), which have not been reported previously. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic medical center. SUBJECTS AND METHODS: Retrospective review of consecutive single-surgeon H&N reconstructions using fasciocutaneous flaps over 5 years. Reconstructions were divided into 2 groups: SCAIFs and FFFs. Patient demographics, surgical parameters, and outcomes were compared statistically between groups. RESULTS: Thirty-four flaps were used in H&N reconstruction (18 SCAIFs and 16 FFFs). There was no difference in patient demographics, distribution of defects, or follow-up (SCAIF 9.2 vs FFF 15.13 months, P = .65) between the 2 groups. The SCAIFs were larger than the FFFs (164.6 ± 60 vs 111 ± 68 cm(2), P < .05) and had shorter total operative times (588 ± 131 vs 816 ± 149 minutes, P < .05). Intensive care unit (ICU) length of stay was shorter for the SCAIF vs the FFF group (1.8 vs 5.6 days, P < .05). Overall morbidity was not significantly different (SCAIF 39% vs FFF 44%, P = NS). CONCLUSION: The SCAIF is a technically simpler and equally reliable sensate fasciocutaneous flap for H&N reconstruction with comparable outcomes, shorter operative time, less ICU stay, and no need for postoperative monitoring when compared with using FFFs. It should be considered a first-choice reconstructive option for complex H&N defects.

The supraclavicular artery island flap (SCAIF) for head and neck reconstruction: surgical technique and refinements.

OBJECTIVE: We have found the supraclavicular artery island flap (SCAIF) to be a reliable, first-line tool for the reconstruction of complex head and neck defects. Here, we review our technique of flap elevation and summarize the current literature citing important contributions in the evolution of this flap. DATA SOURCES: Medline literature review of supraclavicular artery island flap or shoulder flap in head and neck reconstruction with particular emphasis on developments within the past 5 years. REVIEW METHODS: Literature review of technique, indications, anatomy, modification, and outcomes of the supraclavicular artery island flap. CONCLUSION: The supraclavicular artery island flap is an important and reliable option in head and neck reconstruction. We use the flap routinely in our practice as a first-line technique when fasciocutaneous soft-tissue reconstruction is required, and we provide a detailed summary of the flap elevation and inset. IMPLICATIONS FOR PRACTICE: The supraclavicular artery island flap is a safe, reliable, technically simple, sensate, thin, pliable fasciocutaneous regional flap option that has low morbidity. It provides sensate, single-stage reconstruction for a variety of head and neck defects and should be considered as a first-line option in head and neck reconstruction.

Quality of innervation in sensate medial plantar flaps for heel reconstruction.

BACKGROUND: Reconstruction of the heel represents a difficult challenge for surgeons, given the demand for thick, durable skin capable of withstanding both pressure and shear. The authors describe the use of a sensate medial plantar flap for heel reconstruction in three patients and document the long-term retention of sensation compared with the contralateral uninjured heel and corresponding donor site. METHODS: A medial plantar flap was harvested to include the branch of the medial plantar nerve to the instep to preserve innervation. Sharp pain, light and deep pressure, vibration, cold temperature, and static and dynamic two-point discrimination were examined between 6 months and 1 year after surgery. RESULTS: Sharp pain, vibration, and deep pressure sensation were present equally in the medial plantar flap, contralateral heel, and contralateral instep. Cold perception, light pressure, and static two-point and dynamic two-point discrimination were significantly less in the normal contralateral heel when compared with the heel reconstructed by the innervated flap. There were no significant differences in sensation between the medial plantar flap and the contralateral instep. CONCLUSIONS: The medial plantar flap is capable of providing durable, sensate coverage of plantar hindfoot defects with minimal donor-site morbidity. Furthermore, that sensation remains identical to that of the instep donor site and superior to that of the normal heel pad.

Professional perceptions of plastic and reconstructive surgery: what primary care physicians think.

BACKGROUND: The great breadth of the specialty of plastic surgery is often misunderstood by practitioners in other specialties and by the public at large. The authors investigate the perceptions of primary care physicians in training toward the practice of different areas of plastic and reconstructive surgery. METHODS: A short, anonymous, Web-based survey was administered to residents of internal medicine, family medicine, and pediatrics training programs in the United States. Respondents were asked to choose the specialist they perceived to be an expert for six specific clinical areas, including eyelid surgery, cleft lip and palate surgery, facial fractures, hand surgery, rhinoplasty, and skin cancer of the face. Specialists for selection included the following choices: dermatologist, general surgeon, ophthalmologist, oral and maxillofacial surgeon, orthopedic surgeon, otolaryngologist, and plastic surgeon. RESULTS: A total of 1020 usable survey responses were collected. Respondents believed the following specialists were experts for eyelid surgery (plastic surgeon, 70 percent; ophthalmologist, 59 percent; oral and maxillofacial surgeon, 15 percent; dermatologist, 5 percent; and otolaryngologist, 5 percent); cleft lip and palate surgery (oral and maxillofacial surgeon, 78 percent; plastic surgeon, 57 percent; and otolaryngologist, 36 percent); facial fractures (oral and maxillofacial surgeon, 88 percent; plastic surgeon, 36 percent; otolaryngologist, 30 percent; orthopedic surgeon, 11 percent; general surgeon, 3 percent; and ophthalmologist, 2 percent); hand surgery (orthopedic surgeon, 76 percent; plastic surgeon, 52 percent; and general surgeon, 7 percent); rhinoplasty (plastic surgeon, 76 percent; otolaryngologist, 45 percent; and oral and maxillofacial surgeon, 18 percent); and skin cancer of the face (dermatologist, 89 percent; plastic surgeon, 35 percent; oral and maxillofacial surgeon, 9 percent; otolaryngologist, 8 percent; and general surgeon, 7 percent). CONCLUSION: As the field of plastic surgery and other areas of medicine continue to evolve, additional education of internal medicine, pediatrics, and family practice physicians and trainees in the scope of plastic surgery practice will be critical.

Breast reconstruction with perforator flaps.

BACKGROUND: Perforator flaps represent the latest in the evolution of soft-tissue flaps. They allow the transfer of the patient's own skin and fat in a reliable manner, with minimal donor-site morbidity. The powerful perforator flap concept allows transfer of tissue from numerous, well-described donor sites to almost any distant site with suitable recipient vessels. Large-volume flaps can be supported reliably with perforators from areas such as the abdomen, buttock, or flank and transferred microsurgically for breast reconstruction. INDICATIONS: The ideal tissue for breast reconstruction is fat with or without skin, not implants or muscle. Absolute contraindications specific to perforator flaps in the authors' practice include history of previous liposuction of the donor site, some previous donor-site surgery, or active smoking (within 1 month before surgery). TECHNIQUE: Perforator flaps are supplied by blood vessels that arise from named, axial vessels and perforate through or around overlying muscles and septa to vascularize the overlying skin and fat. During flap harvest, these perforators are meticulously dissected free from the surrounding muscle, which is spread in the direction of the muscle fibers and preserved intact. The pedicle is anastomosed to recipient vessels in the chest, and the donor site is closed without the use of mesh. CONCLUSION: Perforator flaps allow for safe, reliable tissue transfer from a variety of sites and provide ideal tissue for breast reconstruction, with minimal donor-site morbidity.

Age-related changes of the orbit and midcheek and the implications for facial rejuvenation.

BACKGROUND: Aging of the midface is complex and poorly understood. Changes occur not only in the facial soft tissues, but also in the underlying bony structure. Computed tomography (CT) imaging was used for investigating characteristics of the bony orbit and the anterior wall of the maxilla in patients of different ages and genders. METHODS: Facial CT scans were performed for 62 patients ranging in age from 21 to 70 years, who were divided into three age groups: 21-30 years, 41-50 years, and 61-70 years. Patients also were grouped by gender. The lengths of the orbital roof and floor and the angle of the anterior wall of the maxilla were recorded on parasagittal images through the midline of the orbit for each patient. RESULTS: The lengths of the orbital roof and floor at their midpoints showed no significant differences between the age groups. When grouped by gender, the lengths were found to be statistically longer for males than for females. The angle between the anterior maxillary wall and the orbital floor was found to have a statistically significant decrease with advancing age among both sexes. CONCLUSION: Bony changes occur in the skeleton of the midcheek with advancing age for both males and females. The anterior maxillary wall retrudes in relation to the bony orbit, which maintains a fixed anteroposterior dimension at its midpoint. These changes should be considered in addressing the aging midface.

Breast reconstruction using perforator flaps.

BACKGROUND: Perforator flaps allow the transfer of the patient's own skin and fat in a reliable manner with minimal donor-site morbidity. The deep inferior epigastric artery (DIEP) and superficial inferior epigastric artery (SIEA) flaps transfer the same tissue from the abdomen to the chest for breast reconstruction as the TRAM flap without sacrificing the rectus muscle or fascia. Gluteal artery perforator (GAP) flaps allow transfer of tissue from the buttock, also with minimal donor-site morbidity. INDICATIONS: Most women requiring tissue transfer to the chest for breast reconstruction or other reasons are candidates for perforator flaps. Absolute contraindications to perforator flap breast reconstruction include history of previous liposuction of the donor site or active smoking (within 1 month prior to surgery). ANATOMY AND TECHNIQUE: The DIEP flap is supplied by intramuscular perforators from the deep inferior epigastric artery and vein. The SIEA flap is based on the SIEA and vein, which arise from the common femoral artery and saphenous bulb. GAP flaps are based on perforators from either the superior or inferior gluteal artery. During flap harvest, these perforators are meticulously dissected free from the surrounding muscle which is spread in the direction of the muscle fibers and preserved intact. The pedicle is anastomosed to recipient vessels in the chest and the donor site is closed without the use of mesh or other materials. CONCLUSIONS: Perforator flaps allow the safe and reliable transfer of abdominal tissue for breast reconstruction.

The in-the-crease inferior gluteal artery perforator flap for breast reconstruction.

BACKGROUND: Perforator free flaps harvested from the abdomen or buttock are excellent options for breast reconstruction. They enable the reconstructive surgeon to recreate a breast with skin and fat while leaving muscle at the donor site undisturbed. The gluteal artery perforator free flap using buttock tissue was first introduced by the authors' group in 1993. Of the 279 gluteal artery perforator flaps, the authors have performed for breast reconstruction, 220 have been based on the superior gluteal artery and 59 have been based on the inferior gluteal artery. The authors have found that for some women with excess tissue in the upper buttock and hip area, use of the gluteal artery perforator flap resulted in an improvement at the donor site, whereas for others the aesthetic unit of the buttock was clearly disrupted. Therefore, the authors have recently been placing the scar in the inferior buttock crease to improve donor-site aesthetics. METHODS: The authors have now performed 31 in-the-crease inferior gluteal artery perforator free flaps for breast reconstruction and found that the results are very favorable. RESULTS: The removal of tissue from the inferior buttock results in a tightened, lifted appearance. The resultant scar is well concealed within the infrabuttock crease, and exposure or injury of the sciatic nerve has not occurred. Extended beveling at this site is also possible, with less risk of causing an unsightly depression. The final aesthetic result of the scar lying within the inferior buttock crease is very favorable. All patients report satisfaction with the donor site. Complications included one total flap loss, two reoperations for venous congestion, one hematoma, two cases with delayed wound healing at the recipient site, and one with delayed wound healing at the buttock. CONCLUSION: The in-the-crease inferior gluteal artery perforator flap from the buttock is now the authors' primary alternative to the deep inferior epigastric perforator flap from the abdomen for breast reconstruction.

Breast reconstruction with the deep inferior epigastric perforator flap: history and an update on current technique.

Perforator flaps allow the transfer of the patient's own skin and fat in a reliable manner with minimal donor site morbidity. For breast reconstruction, the abdomen typically is our primary choice as a donor site. The deep inferior epigastric perforator (DIEP) flap remains our first choice as an abdominal perforator flap and has become a mainstay for the repair of mastectomy defects. It allows the transfer of the same tissue from the abdomen to the chest for breast reconstruction as the TRAM flap without sacrifice of the rectus muscle or fascia. We discuss our current techniques and specific issues related to the surgery. We present the results of 1095 cases of free tissue transfers from the abdomen for reconstruction of the breast.

Breast reconstruction with gluteal artery perforator flaps.

BACKGROUND: Several alternatives exist for breast cancer reconstruction with perforator flaps. For those patients in whom the buttock is the best choice as a source for autologous tissue, the IGAP and SGAP flaps are an excellent option. These flaps allow the reliable transfer of skin and soft tissue from the buttock without the associated donor site morbidity of a muscle flap. INDICATIONS: Most women requiring tissue transfer to the chest from the buttock for breast reconstruction or other reasons are candidates for IGAP or SGAP flaps. Do to an improved donor site contour and scar, we now prefer to use the IGAP to the SGAP flap. Absolute contraindications specific to perforator flap breast reconstruction in our practice include history of previous liposuction of the donor site or active smoking (within 1 month prior to surgery). ANATOMY AND TECHNIQUE: IGAP and SGAP flaps are based on perforators from either the superior or inferior gluteal artery. These perforators are carefully dissected free from the surrounding gluteus maximus muscle, which is spread in the direction of the muscle fibres and safely preserved. The vascular pedicle is anastomosed to recipient vessels in the chest and the donor site closed primarily. CONCLUSIONS: IGAP and SGAP flaps allow the safe and reliable transfer of tissue from the buttock for breast reconstruction as an alternative to soft tissue transfer from an abdominal donor site or even as a first choice in selected patients.
