Skin Coverage of the Middle-Distal Segment of the Leg With a Pedicled Perforator Flap

Objective: This is a clinical study of our experience using pedicle perforator flaps to cover skin defects in the middle and distal segment of the leg. Design: Prospective study. Setting: University hospital. Patients/Intervention: Twenty-four patients underwent treatment of a skin defect in the middle or distal segment of the leg by means of pedicled flaps based on perforating arteries. The perforating arteries were located before the operation by means of echo-Doppler examination. The flaps were planned in propeller fashion (21 cases) and as advancement (three cases). Main Outcome Measurements: The results were evaluated according the origin of perforator flap, size of the flap, and donor area and viability of the flap. The success rate of the echo-Doppler to identify the location of perforator vessel was also evaluated. Results: In nine cases, the perforating vessels originated from the fibular artery, in 10 the posterior tibial artery, and in five the anterior tibial artery. The mean size of the flaps was 5 cm in width by 12 cm in length. The success rate using an echo-Doppler was 87%. The flaps were fully viable in 20 cases and partially viable in four cases. Conclusion: On the basis of these results, it is concluded that perforating flaps are a good choice of treatment for skin losses, especially in the distal segment of the leg, and could be an alternative option for the use of free microsurgical flaps.

Immediate conservative breast surgery reconstruction with perforator flaps: New challenges in the era of partial mastectomy reconstruction?

Introduction: Although the use of local flaps in conservative breast surgery (CBS) reconstruction is a reliable technique, little information has been available regarding outcome following the use of perforator flaps. The purpose of this study is to analyze the feasibility, surgical planning and outcome following CBS reconstruction with intercostal artery perforator (ICAP) flap. Patients/methods: Thirteen patients underwent CBS reconstructions with an ICAP flap. These flaps were raised from adjacent tissue located on the lateral and thoracic region and based on perforators originating from the costal and muscular segment of the intercostal vessels. The technique was indicated in patients with small/moderate volume breasts. Results: Mean time of follow-up was 32 months. Flap complications were evaluated and information on patient satisfaction were collected. 61.5 percent had tumors located in the lower-outer quadrants and 69.2 percent had tumors measuring 2 cm or less (T1). Complications occurred in 3 patients (23%), including wound dehiscence in 2 patients and fat necrosis in one. All cases were treated by conservative approach with a good result. No flap loss or wound infection were reported. 90 percent were either satisfied or very satisfied with their result. Conclusion: The ICAP flap is a reliable technique for immediate CBS reconstruction. The technique is advantageous because it does not require the use of muscle transfer, with minimum donor site morbidity. Success depends on patient selection, coordinated planning with the oncological surgeon and careful intra-operative management. (C) 2011 Elsevier Ltd. All rights reserved.

The subcostal artery perforator flap; an anatomical study

BACKGROUND: Based on a previous clinical case report in which the pedicled subcostal artery perforator flap allowed for the closure of a large defect of the lumbar region, the present study was designed to investigate the anatomy of the subcostal artery perforator flap and to evaluate its potential for wider clinical use. METHODS: A series of 14 human cadavers was studied and 28 subcostal artery perforator flaps were dissected. The location of the perforator vessel was charted against anatomical landmarks. Measurements included the perforator calibre, pedicle length, and flap size following methylene blue injection. The findings were compared by Doppler sonography in 15 volunteers. RESULTS: The subcostal artery perforator was present in all dissected specimens and in all volunteers. Its calibre measured in mean 2mm. The location was constant at the lateral border of the latissimus dorsi muscle and between 1 and 3cm below the lower rib end. The pedicle length reached a mean of 10.5cm when dissected up to the border of the erector spinae musculature. The vascular supply covered a mean flap size of 10x14cm. The in vivo investigations confirmed the constant perforator location from the anatomical landmarks. CONCLUSION: This anatomical study reveals a considerable potential for the clinical use of the subcostal artery perforator flap for defect coverage in the lumbar area, due to its constant and reliable anatomy. Doppler sonography can be helpful in preoperative assessment of the size and the position of the subcostal perforator, thus allowing for an optimal flap design.

Subfascial endoscopic perforator surgery (SEPS) in chronic venous insufficiency. A 14 years experience

Introduction. Subfascial Endoscopic Perforator Surgery (SEPS) enables the direct visualization and section of perforating veins. Morbidity and duration of hospitalization are both less than with conventional open surgery (Linton’s or Felder’s techniques). Patients and methods. A total of 322 legs from 285 patients with a mean age of 56 years (range 23-90) were treated at our Department from May 1996 to January 2010. In 309 cases, an endoscope (ETM Endoskopische Technik GmbH, Berlin, Germany) was introduced through a transverse incision approximately 1.5 cm in length and 10 cm from the tibial tuberosity, as with Linton’s technique. A spacemaker balloon dissector for SEPS, involving a second incision 6 cm from the first, was used in only 13 cases. Results. The procedure used in each case was decided on the basis of preoperative evaluation. SEPS and stripping were performed in 238 limbs (73.91%), SEPS and short stripping in 7 limbs (2.17%), SEPS and crossectomy in 51 limbs (15.84%), and SEPS alone in 26 limbs (8.07%). 103 patients presented a total of 158 trophic ulcers; the healing time was between 1 and 3 months, with a healing rate of 82.91% after 1 month and 98.73% after 3 months. Conclusion. Subfascial ligature of perforating veins is superior to sclerotherapy and minimally invasive suprafascial treatment for the treatment of CVI. It is easy to execute, minimally invasive and has few complications.

Omentum For Mammary Disorders: A 30-year Systematic Review.

Although the safety of applying omentum to the female breast for total breast reconstruction is controversial, it has recently been used to treat certain mammary disorders as well. A systematic review was therefore conducted to analyze and establish the suitability and safety of applying omentum to the breast. Covereing the interval from January 1984 to December 2013, we performed searches in MEDLINE, Embase, SciELO, and Google-Scholar for original articles describing the applicability of greater omentum to the breast and its clinical complications. Sixty observational articles with 985 women were chosen. The main clinical indications were total breast reconstruction after mastectomy due to breast cancer (45 studies), radiation damage (23 studies), and congenital Poland syndrome (4 studies). Altogether, 273 complications were identified among the 985 women treated. The most frequent was flap necrosis (26.74 %). The most serious was injury to the digestive system (1.10 %). There was a 35.48 % incidence of local breast cancer recurrence in eight observational studies on oncological risk. Seven of the eight included only women with advanced cancer. One of these studies reported the incidence and relapse time predominantly according to the primary tumor size. Although the oncological risk remains unclear, there was a high volume of complications that affected the digestive system. These findings suggest that omentum has well established applicability, but only for total breast reconstruction of huge defects, where muscular/myocutaneous or perforator flaps may be unsuitable.

Indications et techniques actuelles de reconstruction mammaire après mastectomie [Indications and techniques of reconstruction after mastectomy].

Reconstructive surgery takes an important place in breast cancer treatment. Immediate breast reconstruction is performed during the same operation as mastectomy. It is contraindicated following radiotherapy. Reconstruction performed after mastectomy is called differed breast reconstruction. It is completed 6 months after chemotherapy and 1 year after radiotherapy. Prosthetic breast reconstruction is indicated when tissues are of good qualities and breast are small. Autologous reconstruction is performed in case of radiotherapy or large breast. After breast reconstruction, imperfections can be corrected with autologous fat injection.

The v-y latissimus dorsi musculocutaneous flap in the reconstruction of large posterior chest wall defects.

Posterior chest wall defects are frequently encountered after excision of tumors as a result of trauma or in the setting of wound dehiscence after spine surgery. Various pedicled fasciocutaneous and musculocutaneous flaps have been described for the coverage of these wounds. The advent of perforator flaps has allowed the preservation of muscle function but their bulk is limited. Musculocutaneous flaps remain widely employed. The trapezius and the latissimus dorsi (LD) flaps have been used extensively for upper and middle posterior chest wounds, respectively. Their bulk allows for obliteration of the dead space in deep wounds. The average width of the LD skin paddle is limited to 10-12 cm if closure of the donor site is expected without skin grafting. In 2001 a modification of the skin paddle design was introduced in order to allow large flaps to be raised without requiring grafts or flaps for donor site closure. This V-Y pattern allows coverage of large anterior chest defects after mastectomy. We have modified this flap to allow its use for posterior chest wall defects. We describe the flap design, its indications, and its limitations with three clinical cases. Level of Evidence V This journal requires that authors assign a level of evidence to each article.

An individualized approach to abdominoplasty in the presence of bilateral subcostal scars after open gastric bypass.

BACKGROUND: Patients requiring surgical skin excision after massive weight loss are challenging and require an individualized approach. The characteristic abdominal deformity includes a draping apron of panniculus, occasionally associated with previous transverse surgical scars from open gastric bypass surgery in the upper abdomen, which compromise blood supply of the abdominal skin. METHODS: We propose four different surgical techniques for safe abdominal body contouring in the presence of such scars: (1) a limited abdominoplasty of the lower abdomen is performed, and then contouring is completed by a reversed abdominoplasty with scar positioning in the submammary folds; (2) a one-stage procedure characterized by skin resection in the upper and lower abdomen, in which blood supply of the skin island between the submammary and suprapubic incisions is ensured by periumbilical perforators; (3) a perforator-sparing abdominoplasty with selective dissection of periumbilical abdominal wall perforators to secure flap blood supply and allow complete flap undermining up to the xyphoid process; (4) for patients with extensive excess skin, a modified Fleur-de-Lys abdominoplasty performed in such a way that the old transverse scar is transformed into a vertical scar. RESULTS: The treatment of four exemplary patients is described. All techniques yielded good esthetic and functional results through preservation of abdominal blood supply. CONCLUSION: Through an individualized approach, adequate abdominal body contouring can be performed safely, even in the presence of transverse surgical scars in the upper abdomen.

Plastic surgery in chest wall reconstruction: relevant aspects - case series

Objective: to discuss the participation of Plastic Surgery in the reconstruction of the chest wall, highlighting relevant aspects of interdisciplinaryness. Methods: we analyzed charts from 20 patients who underwent extensive resection of the thoracic integument, between 2000 and 2014, recording the indication of resection, the extent and depth of the raw areas, types of reconstructions performed and complications. Results: among the 20 patients, averaging 55 years old, five were males and 15 females. They resections were: one squamous cell carcinoma, two basal cell carcinomas, five chondrosarcomas and 12 breast tumors. The extent of the bloody areas ranged from 4x9 cm to 25x40 cm. In 12 patients the resection included the muscular plane. In the remaining eight, the tumor removal achieved a total wall thickness. For reconstruction we used: one muscular flap associated with skin grafting, nine flaps and ten regional fasciocutaneous flaps. Two patients undergoing reconstruction with fasciocutaneous flaps had partially suffering of the flap, solved with employment of a myocutaneous flap. The other patients displayed no complications with the techniques used, requiring only one surgery. Conclusion: the proper assessment of local tissues and flaps available for reconstruction, in addition to the successful integration of Plastic Surgery with the specialties involved in the treatment, enable extensive resections of the chest wall and reconstructions that provide patient recovery.

Impacto de dos técnicas quirúrgicas sobre la recaída local de carcinoma de mama en pacientes de una clínica de Bogotá D.C.

Introducción: El carcinoma de mama es el tumor maligno más frecuente entre las mujeres y representa una significativa mortalidad en los países en vías de desarrollo. Según datos del Instituto Nacional de Cancerología en el 2010 se reportaron 672 nuevos casos de cáncer de mama, lo que representó el 18% de todos los tumores malignos en mujeres. Durante las últimas 3 décadas las técnicas quirúrgicas para el tratamiento del cáncer de mama han presentado un cambio significativo y proponen disminución de procedimientos agresivos y radicales, intervenciones como: mastectomía radical modificada, cirugía conservadora y la disección de ganglio centinela son ejemplos claros de esta evolución asociado al incremento de la reconstrucción mamaria inmediata. Metodología: Estudio observacional tipo cohorte retrospectivo en el cual se revisó una base de datos de pacientes con cáncer de mama de las cuales 632 fueron sometidas a mastectomía radical con preservación de piel y complejo areola-pezón y mastectomía radical con preservación de piel sin preservación del complejo areola-pezón, los dos procedimientos asociados a reconstrucción mamaria inmediata y se comparó la frecuencia de recaída local entre los dos grupos. Resultados: De las 632 pacientes estudiadas al 30.5% se les realizo preservación del complejo areola pezón. Las mujeres a quienes se les realizó preservación del complejo areola pezón presentaron menor sobrevida a la recaída local a 10 años (80.51%) comparado con las mujeres a quienes no se les preservó el complejo areola pezón (87.40%), sin embargo no se encontró diferencia estadísticamente significativa para determinar que las probabilidades de sobrevida sean diferentes. Discusión: No se evidenció diferencia estadísticamente significativa entre los 2 procedimientos quirúrgicos (con y sin preservación del complejo areola pezón) en relación a la recaída local, estudios retrospectivos no han evidenciado una mayor tasa de recaídas locales en pacientes a quienes se les preserva el complejo areola-pezón, sin embargo hacen falta estudios prospectivos y aleatorizados que puedan otorgar un mayor sustento científico que garantice la seguridad de la preservación del complejo areola-pezón.

Comparación de cambios clínicos y hemodinámicos en pacientes con insuficiencia venosa mixta según tipo de manejo.

Existen varias causas de la insuficiencia venosa profunda, la insuficiencia venosa superficial es una de ellas; por tal motivo, una intervención activa de la insuficiencia superficial ya sea cirugía convencional, esclerosis o radiofrecuencia mejora el reflujo del sistema venoso profundo. En nuestro medio no se acostumbra a intervenir los pacientes con insuficiencia venosa mixta bajo la creencia de exacerbar la enfermedad o generar complicaciones. Se pretende documentar los cambios clínicos y hemodinámicos en pacientes con insuficiencia venosa mixta según tipo de manejo, médico vs quirúrgico

Application of a new laser Doppler imaging system in planning and monitoring of surgical flaps

There is a demand for technologies able to assess the perfusion of surgical flaps quantitatively and reliably to avoid ischemic complications. The aim of this study is to test a new high-speed high-definition laser Doppler imaging (LDI) system (FluxEXPLORER, Microvascular Imaging, Lausanne, Switzerland) in terms of preoperative mapping of the vascular supply (perforator vessels) and postoperative flow monitoring. The FluxEXPLORER performs perfusion mapping of an area 9 x 9 cm with a resolution of 256 x 256 pixels within 6 s in high-definition imaging mode. The sensitivity and predictability to localize perforators is expressed by the coincidence of preoperatively assessed LDI high flow spots with intraoperatively verified perforators in nine patients. 18 free flaps are monitored before, during, and after total ischemia. 63% of all verified perforators correspond to a high flow spot, and 38% of all high flow spots correspond to a verified perforator (positive predictive value). All perfused flaps reveal a value of above 221 perfusion units (PUs), and all values obtained in the ischemic flaps are beneath 187 PU. In summary, we conclude that the present LDI system can serve as a reliable, fast, and easy-to-handle tool to detect ischemia in free flaps, whereas perforator vessels cannot be detected appropriately.

One hundred fascia-sparing myocutaneous rectus abdominis flaps: An update

Major efforts have been undertaken to reduce donor-site morbidity after abdominal flaps, which eventually culminated in the introduction of the deep inferior epigastric perforator (DIEP) flap. However, due to anatomical variations (absence of dominant perforators) and the risk of ischaemic complications, the selection of patients qualifying for a DIEP flap is limited. Furthermore, DIEP flaps can only be used as free flaps. We present our long-term experience with a dissection technique of rectus abdominis myocutaneous (RAM) flaps that was developed to circumvent these drawbacks. The dissection is characterised by preventing to sacrifice any perforators nourishing the flap and by fully preserving the anterior rectus sheath, but not the muscle. The study comprises a consecutive series of prospectively assessed patients, treated between February 2000 and April 2008. A total of 100 fascia-sparing RAM flaps were operated on 97 patients (age 22-84 years, median 64 years). Free flaps were mainly used for breast reconstruction (47 flaps/24 patients), and cranially (34) or caudally (19) pedicled flaps for soft-tissue coverage after sternectomy, urogenital tumour resection or rectum amputation. Eighty patients had a total of 213 risk factors, such as cardiovascular diseases, obesity, hyperlipidaemia, diabetes mellitus, smoking or steroid medication. Partial tissue loss (skin or fat necrosis) occurred in 13 flaps, out of which seven required surgical revision. The ischaemic complications were evenly distributed between the patient subsets. At a follow-up of 2-89 months (median 20 months), one patient showed a flap harvest-related abdominal bulge after bilateral-free transverse rectus abdominis myocutaneous (TRAM) flap. We conclude that the present dissection technique provides maximal perforator-related perfusion and minimal donor-site morbidity even in pedicled flaps and high-risk patients. In free flaps, it may, therefore, be recommended as an alternative to the DIEP flap.
