ABSTRACT

Abstract Objective To evaluate the use of external fixators in the delta-type kickstand configuration as an adjuvant method in the postoperative period of patients submitted to free flaps in the lower limbs. Methods A total of 17 external delta fixators were used in patients submitted to free flaps in the lower limbs. The surgical technique was performed in a standardized manner, with the distal pin located 6 cm proximally to the anastomosis, and the proximal pin, 6 cm distally to the anterior tuberosity of the tibia. Results The mean age of the sample was of 34.76 years (range: 15 to 66 years). In total, 11 men and 6 women were selected. The posterior tibial artery was used in 14 cases, and the anterior tibial artery, in 3 cases. The mean time of use of the external fixators was of 3.88 weeks. The rate of reoperation was of 17.64%; that of retail loss was of 11.76%; that of success rate was of 88.23%; and the rate of infection was of 5.9%. Conclusion The use of delta-type fixators as an adjunct method in the postoperative period is reliable; however, more studies are needed to evaluate its true role in the postoperative period.

ABSTRACT

ABSTRACT Purpose: To evaluate surgical complications and oncological outcomes of patients submitted to primary radical inguinal surgical debulking (PRISD) and myocutaneous pediculate flap reconstruction (MPFR) for locally advanced penile cancer (PC). Materials and Methods: Forty-two patients with ulcerated and/or fixed bulky inguinal masses underwent unilateral or bilateral PRISD with MPFR. Tensor fascia lata flap (TFL) was the standard of care for all patients. Additional use of the gracilis flap (GF) was carried out when necessary. Contra-lateral radical inguinal lymphadenectomy (RIL) was conduced when PRISD was performed unilaterally. Surgical complications were analyzed and stratified into minor and major according to the Bevan-Thomas classification. Adjunctive treatments were assessed and oncological outcomes analyzed. Results: Of the 42 patients evaluated, 10 (23.8%) underwent bilateral PRISD and 32 (76.2%) unilateral PRISD with contra-lateral RIL, totaling 84 lymphadenectomies. A total of 62 MPFRs were performed, 52 with TFL and 10 with GF. A total of 53 complications were identified, 49 related to PRISD with MPFR and 4 to RIL. Adjuvant chemotherapy was carried out in 16 patients. Median follow-up was 10.8 months with a median overall survival (OS) of 14.0 months against 6.0 months (p=0.006) for patients submitted to PRISD with adjuvant chemotherapy in relation to surgery alone. Conclusions: PRISD alone for advanced loco-regional PC is unlikely to promote long-term survival, although it can lead to temporary local control of the disease. Despite the feasibility of the procedure, it is related to high incidence of complications. Surgical treatment with adjuvant chemotherapy is associated with improved OS.

ABSTRACT

Los labios son repliegues músculo membranosos móviles que se encuentran en la entrada de la cavidad oral, y tienen como funcionalidad proporcionar competencia para la cavidad oral durante la masticación y el reposo. Bozzola y cols., en 1989, describieron la arteria bucal como el principal pedículo para el músculo buccinador. El objetivo de este trabajo es demostrar la efectividad del colgajo miomucoso del buccinador para reconstrucción del labio inferior en un paciente con hemangioma congénito. Este es un estudio longitudinal de tipo retrospectivo, con resultado descriptivo, que se le realizó a un paciente masculino de 32 años, para cubrimiento de defecto de lesión en labio inferior secundario a hemangioma congénito utilizando la reconstrucción con colgajo miomucoso del buccinador. El colgajo miomucoso del buccinador o colgajo yugal se considera uno de los mejores colgajos locales para la reconstrucción del labio inferior, sea cual fuere la causa, por su fácil disección y versatilidad debido a que tiene una tasa de sobrevida muy elevada con mínimas complicaciones en el posoperatorio. Nuestros resultados obtenidos concuerdan con los resultados ya publicados por diferentes autores, que llegan a las mismas conclusiones; aunque existen varias técnicas con colgajos locales para la reconstrucción del labio inferior, el colgajo del músculo buccinador o yugal se considera como una de las principales alternativas, ya que puede lograrse un labio funcional y estético.


The lips are mobile muscle membranous folds, found at the entrance of the oral cavity, whose function is to provide competition for the oral cavity during chewing and rest. Bozzola et al. in 1989, they described the buccal artery as the main pedicle for the Buccinator Muscle. The objective of this work is to demonstrate the effectiveness of the buccinator myomucosal flap for reconstruction of the lower lip in a patient with congenital hemangioma. This is a retrospective longitudinal study, with descriptive results, which was performed in a 32-year-old male patient to cover a lower lip lesion defect secondary to congenital hemangioma using buccinator myomucosal flap reconstruction. The buccinator myomucosal flap or jugal flap is considered one of the best local flaps for the reconstruction of the lower lip whatever the cause, due to its easy dissection and versatility due to the fact that it has a very high survival rate with minimal complications in the postoperative period. Our obtained results agree with the results already published by different authors, reaching the same conclusions; Although there are several techniques with local flaps for the reconstruction of the lower lip, the buccinator or jugal muscle flap is considered one of the main alternatives, since a functional and aesthetic lip can be achieved.

ABSTRACT

Resumen Se presentan casos clínicos operados con la técnica de reconstrucción mamaria de grande dorsal Vd, y se muestra un procedimiento quirúrgico que permite dar un mejor terminado en cuanto a simetría, volumen y proyección. Se muestran 4 casos de reconstrucción tardía, de los cuales 2 fueron reconstrucciones tardías propiamente dichas y los otros 2 con reconstrucciones previas con complicaciones (un caso de necrosis previa de TRAM y otro con mal posicionamiento de la prótesis). Se resalta la utilización de un sistema de cierre asistido por vacío (sistema de presión negativa), un sistema no invasivo y dinámico que ayuda a promover la cicatrización en el lugar de la herida, lo que favorece la reducción del área de la herida, eliminando el exceso de fluidos y estimulando la angiogénesis. Los 4 casos se atendieron en el Instituto Nacional de Cancerología de Colombia, la Clínica San Diego y el Hospital Departamental de Villavicencio.


Abstract There are clinical cases operated with the large dorsal breast reconstruction technique Vd, and a surgical procedure is shown that allows a better finish in terms of symmetry, volume and projection. Four cases of late reconstruction are shown, of which 2 were late reconstructions themselves and the other 2 with previous reconstructions with complications (one case of previous TRAM necrosis and another with poor positioning of the prosthesis). The use of a vacuum assisted closure system (negative pressure system), a non-invasive and dynamic system that helps promote healing at the site of the wound, which favors the reduction of the wound area, eliminating excess fluids and stimulating angiogenesis. The 4 cases were treated at the National Cancer Institute of Colombia, the San Diego Clinic and the Villavicencio Departmental Hospital.

ABSTRACT

ABSTRACT Background: Abdominoperineal excision of the rectum (APR) remains the only potential curative treatment for very low rectal adenocarcinoma and squamous cell carcinoma of the anus. Yet, it implies a significant perineal exenteration and has set the attention on the perineal reconstruction. Aim: To present technique used in one case of APR for anal cancer, with resection of the vaginal posterior wall with large perineal defect which has called for the necessity of a flap for reconstruction Method: To cover the large perineal defect and reconstruct the posterior vaginal wall was perform a standardized and reproducible surgical technique using oblique rectus abdominis myocutaneous (ORAM) flap. The overlying skin of this flap is thick and well vascularized by both superficial branches and perforators of the superior epigastric artery and the deep inferior epigastric artery which serves as the vascular pedicle for the ORAM flap. Results: This procedure was applied in a 65-year-old woman with recurrent squamous cell carcinoma of the anus infiltrating the posterior wall of the vagina. Was performed an APR with en-bloc resection of the vaginal posterior wall in order to achieve tumor-free margins. Postoperative course was uneventful and she was discharged home at postoperative day 9. Final pathological report confirmed the oncological adequacy of the procedure (R0) and showed a rypT4N0 lesion. Conclusion: Flap reconstruction is an effective way to cover the perineal wound reducing both perineal complication rate and wound healing delay. The ORAM is particularly interesting for female whose tumors require resection and subsequent reconstruction of the posterior wall of the vagina.


RESUMO Racional: A amputação abdominoperineal do reto (APR) continua sendo o único tratamento curativo nos casos de adenocarcinoma retal muito baixo e carcinoma espinocelular do ânus. No entanto, implica em exenteração perineal significativa e exige atenção na reconstrução perineal. Objetivo: Propor, ilustrando com um caso clinico, proposta de APR para câncer anal com ressecção da parede posterior da vagina com cobertura do grande defeito perineal através de reconstrução com retalho miocutâneo oblíquo do reto abdominal (ORAM). Método: Para cobrir o defeito e reconstruir a parede vaginal posterior, realizou-se técnica de retalho miocutâneo oblíquo do reto abdominal (ORAM). A pele subjacente desse retalho por ser espessa e bem vascularizada por ramos perforantes superficiais da artéria epigástrica superior e pela artéria epigástrica inferior profunda serviu como pedículo vascular. Resultado: Este procedimento foi aplicado em uma mulher de 65 anos com recidiva de carcinoma espinocelular do ânus infiltrado na parede posterior da vagina. Foi realizada APR com ressecção em bloco da parede posterior vaginal com o objetivo de obter margens livres de tumor. O pós-operatório transcorreu sem intercorrências e a paciente recebeu alta hospitalar no 9° dia pós-operatório. O relatório patológico final confirmou a adequação oncológica do procedimento (R0) e mostrou uma lesão rypT4N0 de 6,5 cm. Conclusão: A reconstrução perineal com utilização de retalho é maneira eficaz de fechar a ferida operatória, reduzindo a taxa de complicações perineais e o atraso na cicatrização. O retalho de tipo ORAM é particularmente interessante para mulheres cujos tumores requerem ressecção e subsequente reconstrução da parede posterior da vagina.

ABSTRACT

PURPOSE: The creation of the nipple-areola complex is the final stage in breast reconstruction and highly affects patient satisfaction. The neo-nipple is well known to shrink over time, particularly in the nipple projection. Currently, no reconstruction technique is clearly superior in terms of nipple size maintenance. We evaluated nipple size changes among several methods of breast mound reconstruction. METHODS: Seventy-eight patients received nipple-areola complex reconstruction secondarily after breast reconstruction. C-V flap nipple reconstructions were performed using a free transverse rectus abdominis myocutaneous (TRAM) flap in 25 cases (TRAM group), a latissimus dorsi (LD) myocutaneous flap in 27 cases (LD group), and an implant in 26 cases (implant group). The circumference and projection of the neo-nipple were measured using a flexible ruler, immediately after reconstruction and average 10 months after surgery. RESULTS: The overall circumference and projection at the final measurement were 91.43% ± 7.11% and 62.16% ± 21.55%, respectively, of immediate postoperative values. The change in circumference did not significantly differ among the 3 groups. In contrast, the change in projection was significantly worse in implant group compared to that in TRAM and LD groups. In addition, among the patients in implant group, greater inflation was significantly associated with greater decrease in the nipple projection. CONCLUSION: Breast mound reconstruction with autologous musculocutaneous flap techniques achieves better long-term maintenance of the neo-nipple projection compared to that achieved with expanded tissue and implantation. Considering the prospective loss of long-term nipple dimension, the preoperative design should be oversized in accordance with its origin in mound reconstruction.

ABSTRACT

The syndrome of the trephined is a neurologic phenomenon that manifests as sudden decline in cognition, behavior, and sensorimotor function due to loss of intracranial domain. This scenario typically occurs in the setting of large craniectomy defects, resulting from trauma, infection, and/or oncologic extirpation. Cranioplasty has been shown to reverse these symptoms by normalizing cerebral hemodynamics and metabolism. However, successful reconstruction may be difficult in patients with complex and/or hostile calvarial defects. We present the case of a 48-year-old male with a large cranial bone defect, who failed autologous cranioplasty secondary to infection, and developed rapid neurologic deterioration leading to a near-vegetative state. Following debridement and antibiotic therapy, delayed cranioplasty was accomplished using a polyetheretherketone (PEEK) implant with free chimeric latissimus dorsi/serratus anterior myocutaneous flap transfer for vascularized resurfacing. Significant improvements in cognition and motor skill were noted in the early postoperative period. At 6-month follow-up, the patient had regained the ability to speak, ambulate and self-feed—correlating with evidence of cerebral/ventricular re-expansion on computed tomography. Based on our findings, we advocate delayed alloplastic implantation with total vascularized soft tissue coverage as a viable alternative for reconstructing extensive, hostile calvarial defects in patients with the syndrome of the trephined.

ABSTRACT

BACKGROUND: In immediate breast reconstruction using an extended latissimus dorsi musculocutaneous (eLDMC) flap, the volume of the flap decreases, which causes a secondary deformity of the breast shape. Since little research has investigated this decrease in muscle volume, the authors conducted an objective study to characterize the decrease in muscle volume after breast reconstruction using an eLDMC flap. METHODS: Research was conducted from October 2011 to November 2016. The subjects included 23 patients who underwent mastectomy due to breast cancer, received immediate reconstruction using an eLDMC flap without any adjuvant chemotherapy or radiotherapy, and received a computed tomography (CT) scan from days 7 to 10 after surgery and 6 to 8 months postoperatively. In 10 patients, an additional CT scan was conducted 18 months postoperatively. Axial CT scans were utilized to measure the volumetric change of the latissimus dorsi muscle during the follow-up period. RESULTS: In the 23 patients, an average decrease of 54.5% was observed in the latissimus dorsi muscle volume between the images obtained immediately postoperatively and the scans obtained 6 to 8 months after surgery. Ten patients showed an average additional decrease of 11.9% from 6–8 months to 18 months after surgery. CONCLUSIONS: We studied changes in the volume of the latissimus dorsi muscle after surgery using an eLDMC flap performed after a mastectomy without adjuvant chemotherapy or radiotherapy. In this study, we found that immediate breast reconstruction using a latissimus dorsi muscle flap led to a decrease in muscle volume of up to 50%.

ABSTRACT

BACKGROUND: Thoracodorsal vessels (TDVs) and internal mammary vessels (IMVs) have both been widely employed as recipient vessels for use in free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps. However, whether TDVs or IMVs are preferable as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap remains controversial. The purpose of this study was to compare the clinical outcomes when TDVs were used as recipient vessels to those obtained when IMVs were used as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap. METHODS: A retrospective matched-cohort study was performed. We retrospectively reviewed data collected from patients who underwent a free MS-TRAM flap for autologous breast reconstructions after mastectomy between March 2003 and June 2013. After a one-to-one matching using age, 100 autologous breast reconstructions were selected in this study. Of the 100 breast reconstructions, 50 flaps were anastomosed to TDVs and 50 to IMVs. Patient demographics and clinical outcomes including operation time, length of hospital stay, postoperative complications, and aesthetic score were compared between the two groups. RESULTS: No statistically significant differences were found between the two groups in patient demographics and clinical outcomes, including the complication rates and aesthetic scores. There were no major complications such as total or partial flap loss in either group. CONCLUSIONS: The results of our study demonstrate that both TDVs and IMVs were safe and efficient as recipient vessels in terms of the complication rates and aesthetic outcomes.

ABSTRACT

BACKGROUND: Subbrow blepharoplasty (SBB) has advantages over traditional blepharoplasty in that it results in more natural-looking creases and contours and is more effective for lateral periorbital rejuvenation. However, in older patients with sunken upper eyelid, this procedure might make the superior eyelid sulcus appear worse because the thicker upper eyelid tissue in the subbrow area is replaced by thinner tissue. To overcome this limitation, we developed a de-epithelialized musculocutaneous flap for SBB. METHODS: From August 2016 to January 2018, 13 patients with sunken upper eyelid deformity underwent SBB. For each of these patients, a typical SBB incision was made, but the tissue usually removed in SBB was dissected as a flap based on the branch of the ophthalmic vessel. After elevation, the flap was transposed or folded to correct the sunken deformity. The results were assessed by the patients themselves and by three plastic surgeons at 6 months postoperatively. RESULTS: The mean age of the patients was 63 years (range, 47–81 years). There were no postoperative complications related to wound dehiscence, hypertrophic scarring, or sensory changes. All patients and plastic surgeons provided scores indicating good to excellent results and were satisfied with the cosmetic outcomes. All patients reported improved functional visual acuity after surgery. CONCLUSIONS: Our technique is simple and effectively addresses both sunken upper eyelid deformity and dermatochalasis. Unlike fat or dermofat grafting, our new technique does not require an additional donor site, and it is more reliable in terms of vascularity.

ABSTRACT

BACKGROUND: Serial volumetric changes of reconstructed breasts have not been studied in detail. In this study, we analyzed serial volumetric changes of reconstructed and contralateral normal breasts during long-term follow-up, with a focus on the effect of various adjuvant therapies. METHODS: Among all patients who underwent immediate breast reconstruction with a unilateral pedicled transverse rectus abdominis musculocutaneous (p-TRAM) flap, 42 patients with valid data from ≥3 postoperative positron emission tomography-computed tomography (PET-CT) scans were included. The volumes of the reconstructed and normal breasts were measured, and the ratio of flap volume to that of the contralateral breast was calculated. Serial changes in volume and the volume ratio were described, and the effects of chemotherapy, radiation therapy, and hormone therapy on volumetric changes were analyzed. RESULTS: The mean interval between the initial reconstruction and each PET-CT scan was 16.5, 30, and 51 months respectively. Thirty-five, 36, and 10 patients received chemotherapy, hormone therapy, and radiation therapy, respectively. The flap volume at each measurement was 531.0, 539.6, and 538.0 cm3, and the contralateral breast volume was 472.8, 486.4, and 500.8 cm3, respectively. The volume ratio decreased from 115.1% to 113.4%, and finally to 109.6% (P=0.02). Adjuvant therapies showed no significant effects. CONCLUSIONS: We demonstrated that the p-TRAM flap maintained its volume over a long-term follow up, while the volume of the contralateral native breast slowly increased. Moreover, adjuvant breast cancer therapies had no statistically significant effects on the volume of the reconstructed p-TRAM flaps or the contralateral native breasts.

ABSTRACT

In recent years, there has been a notable increase in the rate of refractory donor site seroma, defined as seroma that persists for at least 3 months postoperatively, as the number of breast reconstructions using a latissimus dorsi (LD) musculocutaneous flap has increased. Various factors have been proposed to be related, including smoking, obesity, flap mass, and body weight, and several studies have been conducted to explore treatment methods. Typically, surgical treatment, such as capsulectomy, has been considered for refractory seroma, but in this case report, we describe positive outcomes achieved by using Abnobaviscum to treat three female patients who developed a donor site seroma at least 3 months after breast reconstruction using an LD flap.

ABSTRACT

BACKGROUND: Bilateral microsurgical autologous reconstruction is known to increase operating time, costs, and complications compared to unilateral procedures. This study aimed to determine whether a unilateral pedicled transverse rectus abdominis myocutaneous (TRAM) flap and a unilateral deep inferior epigastric artery perforator (DIEP) free flap could be a feasible option for bilateral reconstruction in selected circumstances. METHODS: A retrospective chart review identified patients who underwent unilateral pedicled TRAM and unilateral DIEP reconstruction for bilateral breast reconstruction between 2011 and 2014. Surgical outcomes, complications, and aesthetic scale questionnaire responses were evaluated. RESULTS: Fourteen patients were included in this study. Ten patients received bilateral immediate reconstruction, while four patients with a previous history of mastectomy underwent unilateral immediate reconstruction and contralateral delayed reconstruction. All flaps survived without any major complications. A case of nipple-areolar skin necrosis on the pedicled TRAM side and a case of mild abdominal bulging at the free DIEP donor site were reported. There was no partial flap necrosis or palpable fat necrosis. On the aesthetic outcome scale, the free DIEP flaps scored significantly higher than did the pedicled TRAM flaps for overall shape, the upper medial and lower lateral quadrant, and the lateral chest wall. CONCLUSIONS: Our findings suggest that a unilateral pedicled TRAM flap together with a unilateral free DIEP flap could be performed as a bridging surgical option as institutions move toward bilateral free-flap reconstructions, as a way to reduce operating time and the risk of microsurgery-related complications with acceptable donor site morbidity and aesthetic outcomes.

ABSTRACT

PURPOSE: The purpose of this study was to assess the effect of quilting suture extent on the latissimus dorsi myocutaneous flap (LDMCF) donor site and the necessity of drainage.METHODS: Clinical data of 136 breast cancer patients, who underwent breast reconstruction using LDMCF between May 2014 and December 2015, were retrospectively reviewed. Patients were divided into three groups. Group A: quilting sutures were performed on half of the LDMCF donor site and a closed suction drain was inserted. Group B: quilting sutures were performed for the entire LDMCF donor site and a closed suction drain was inserted. Group C: quilting sutures were performed for the entire LDMCF donor site and no drain was inserted. The duration of drainage, total drainage, length of hospital stay, number of postoperative aspirations for seroma removal, and total aspirated volume were compared.RESULTS: In the comparison of groups A and B, group B showed better results including the total amount of drained seroma, drain maintenance period, number of aspirations for seroma removal after drainage tube removal, total aspirated seroma, and hospitalization period with statistical significance (P<0.05). In the comparison of groups B and C, group C without drain showed no difference in all other variables except mean total drained seroma volume. Therefore, group C was superior to group A and there was no difference compared to group B with drain, even though the drain was not inserted.CONCLUSION: Total quilting suture at LDMCF donor site can reduce seroma formation and eliminate the need for a drain tube.

ABSTRACT

Abstract Purpose Composite flaps used in reconstructive surgery may intra- and postoperatively suffer from hypoperfusion and/or ischemia-reperfusion influencing wound healing. We aimed to follow-up the effect of ischemia on adipocutaneous flaps' wound healing and microcirculation. Methods In anesthetized rats groin flaps were formed bilaterally. In Control group the flaps were repositioned and sutured back. In Ischemia-Reperfusion (I/R) group before repositioning and suturing the flap pedicles were clamped for 60 minutes. Laser Doppler (LD) fluxmetry and temperature probes were applied on the cranial, central and caudal flap regions before/after preparation and ischemia, re-suturing, and on the 1st-3rd-5th-7th-14th postoperative days, before the final examinations and biopsies for histology. Results Flaps' skin temperature quickly recovered after repositioning. LD values were lower in the I/R group, reaching a significant level by the 3rd postoperative day, and remained lowered till the 14th day. The magnitude of alterations differed in the flap regions. Histologically normal wound healing process was seen, except for some I/R flaps, where hypertrophized mammary glands were found. Conclusions Short-term ischemia could influence flap microcirculation and wound healing, and may result in hypertrophized mammary glands. Laser Doppler could be used to evaluate intra- and postoperative microcirculatory changes and may have significance in predicting complications.

ABSTRACT

Objetivos: Analizar los resultados de reconstrucción mamaria con colgajo musculocutáneo de recto abdominal con isla transversa de piel (TRAM) en el Servicio de Cirugía del Hospital El Pino. Materiales y Métodos: Estudio retrospectivo de pacientes sometidas a mastectomía por cáncer de mama y posterior reconstrucción con colgajo TRAM pediculado en los últimos 12 años (2005-2017). Resultados: Se realizaron 12 reconstrucciones mamarias, 6 fueron con colgajo TRAM pediculado. La mayoría de las pacientes recibieron tratamiento adyuvante con radioterapia (1 caso), quimioterapia (1 caso), quimioterapia + radioterapia (2 casos). El tiempo transcurrido entre la mastectomía y reconstrucción mamaria fue en promedio de 2,5 años. Se produjeron 4 complicaciones (66,7%) que necesitaron reintervención: hematoma posoperatorio precoz, infección y necrosis grasas de colgajo, dehiscencia de sutura abdominal, necrosis grasa + fibrosis de colgajo TRAM. La evaluación de los resultados fue subjetiva obteniéndose muy buenos resultados en el 66,7% de los casos. No hubo complicaciones en sitio donante. Discusión: El colgajo TRAM pediculado es el tejido autólogo más utilizado en reconstrucción mamaria. Su tasa de complicación es de 26% muy por debajo a lo obtenido en nuestra experiencia. Las principales complicaciones son fibrosis y necrosis grasa de colgajo, pérdida de colgajo, seroma e infección siendo la necrosis grasa la más frecuente en nuestra serie. El uso de colgajo TRAM otorga mayor satisfacción con apariencia, tamaño y sensación del seno. Debido a los resultados obtenidos creemos que el colgajo TRAM pediculado es una excelente alternativa de reconstrucción mamaria en nuestro hospital.


Objectives: To analyze the results of breast reconstruction with musculocutaneous flap of the rectus abdominis with transverse skin island (TRAM) in the Service of Surgery of El Pino Hospital. Materials and Methods: Retrospective study of patients undergoing mastectomy for breast cancer and subsequent reconstruction with pedicled TRAM flap in the last 12 years (2005-2017). Results: 12 mammary reconstructions were performed, 6 were with pedicled TRAM flap. The majority of patients received adjuvant treatment with radiotherapy (1 case), chemotherapy (1 case), chemotherapy + radiotherapy (2 cases). The time elapsed between the mastectomy and breast reconstruction was on average 2.5 years. There were 4 complications (66.7%) that required reintervention: early postoperative hematoma, infection and flap fat necrosis, abdominal suture dehiscence, fat necrosis + TRAM flap fibrosis. The evaluation of the results was subjective, obtaining very good results in 66.7% of the cases. There were no complications in the donor site. Discussion: The pedicled TRAM flap is the most used autologous tissue in breast reconstruction. Its complication rate is 26%, much lower than that obtained in our experience. The main complications are fibrosis and flap fat necrosis, flap loss, seroma and infection, with fat necrosis being the most frequent in our series. The use of TRAM flap gives greater satisfaction with appearance, size and sensation of the breast. Due to the results obtained, we believe that the pedicled TRAM flap is an excellent alternative for breast reconstruction in our hospital.
