Descriptive anatomy of the inferior epigastric, subscapular and internal thoracic vascular pedicles in three domestic mammals: A comparative study.

The descriptive anatomy of the inferior epigastric, subscapular and internal thoracic vascular pedicles of domestic animals is not fully known. Improvement of our knowledge in this field could lead to better development of animal models for both pedagogical purposes and surgical experimentation. The objective of this comparative study was to describe the descriptive anatomy of the inferior epigastric, subscapular and internal thoracic pedicles in three domestic mammals commonly used as animal models for experimentation. Our study focuses on the anatomical description of these vascular pedicles in the rat (Rattus norvegicus) (n=1), the rabbit (Oryctolagus cuniculus) (n=1) and the pig (Sus scrofa domesticus) (n=1). A comparative and analytical study of these vessels (origin, path, caliber, termination) with those of humans was carried out. The superficial inferior epigastric vascular pedicles have been identified only in rats and pigs. The deep inferior epigastric, subscapular and internal thoracic pedicles were identified in the three mammals studied. No perforator vessels for the subcutaneous tissue and skin were identify from the deep inferior epigastric pedicles. The anatomical characteristics (origin, path, termination) of these vascular pedicles in rabbits seems to be the closest to that of humans. However the caliber of these vessels is around a millimeter compared to a 2.0-3.0mm in humans. This comparative study allowed us to identify and better characterize the morphological characteristics of these vascular pedicles in three domestic mammals, a step prior improving the development of animal models intended for pedagogical or experimental purposes in the field of microsurgical free flaps.

Omental flap for treatment of spondylodiscitis with lumbosacral dehiscence: A case report.

We report a case of pedicled omental flap use together with osteosynthesis treatment of a chronic L4-L5 spondylodiscitis due to a large sacral eschar. The 43-years-old patient was paraplegic and had depleted regional flaps solutions due to multiple previous surgeries. The procedure was carried out in supine position then in prone position whereby the dissected flap was recovered through the spine. The surgery was performed by a multidisciplinary team. First, we used an anterior approach for spine osteosynthesis with a metal implant and flap harvest. Then, in a prone position, we completed the vertebral reconstruction by an L3 athrodesis to the pelvis. The flap was recovered through the spine defect, on the side of the implant. It was a right sided pedicled. Complete wound healing was 120 days. The omental flap proved to be a reliable solution in the absence of recipient vessels for free flap transfer and depleted regional flap solutions. It also spared the latissimus dorsi muscle required for a wheelchair user as in our case. The omental flap is still performed in spine surgery especially in oncologic context to prevent wound dehiscence and for spondylodiscitis coverage. The anterior approach allows for both spine osteosynthesis and flap dissection.

[Clinical photography by smartphone in plastic surgery and protection of personal data: Development of a secured platform and application on 979 patients]. / Photographie clinique par smartphone en chirurgie plastique et protection des données personnelles : développement d'une plateforme sécurisée et application sur 979 patients.

BACKGROUND: The clinical photography in plastic and reconstructive surgery has known a numerical breakthrough. The storage of online data, massive means of analysis such as facial recognitions algorithms poses a serious issue when it comes to the protection of personal data. We will assess a platform's benefits in connection with the computerized medical record, which will allow keeping the photos filed and centralized in a smart and secure manner. METHOD: We interviewed 300 plastic surgeons about the role of smartphone in their clinical practice. Concomitantly, we developed an innovative platform called Surgeon©, a secure way to index, file and send photographs with a smartphone on our hospital's server. Each photographic sequence was qualified using a specific form. We then collected prospectively, between May 1st 2017 and March 30th 2018, the number of patients photographed, the number of sequences and photographs taken and the average number of sequences per patient. RESULTS: Out of 86 French plastic surgeons surveyed, 81% say that they could not go on with their daily practice today without their smartphone. Photographs taken were stored in their smartphones (50%) or synced with virtual storage (25.6%). A majority (80.2%) would use a dedicated secured smartphone application. Our application allowed us to photograph 979 patients, or 2345 sequences and 8112 photographs, with an average of 2.28 sequences per patient. CONCLUSION: Thanks to its ergonomics and security, this platform can be set up in a hospital ward and beyond.

Secondary bladder exstrophy repair with a bilateral gracilis muscle flap in an adult female patient: Case report of an original procedure.

Classical bladder exstrophy (CBE), affecting 1 birth out of 30,000, is characterized by an evaginated bladder plate through a defect in the lower abdominal wall, multiple abdominal wall anomalies including a pubic bone arch dehiscence. Numerous approaches from childhood to adulthood are thus required, depending on the severity of the deformity, including the associated genital anomalies. We report the case of a 19-year-old woman with CBE with a history of three-failed primary closure. We performed a secondary neck closure with a concomitant suspension of the bladder neck and reconstruction of the lower abdominal wall using a bilateral gracilis muscle flap transposition. The early postoperative course was uneventful. The patient was discharged at day ten postoperatively. The upper part of the genital sutures (labia minora) secondary healed in three weeks. Assessment at 2, 6 and 16 months postoperatively, respectively noticed a complete healing with successful sexual intercourses, perceived gracilis contraction by the patient, and finally, recent attempts to get pregnant. Neither urinary infection nor urinary leaks occurred. Bilateral crossed gracilis muscles transfer linking both rectus abdominis muscle in front of the reconstructed bladder neck might benefit to bladder exstrophy patients.

[Autologous breast reconstruction by deep inferior epigastric free flap: Classic and minimally invasive extraperitoneal approaches]. / Reconstruction mammaire autologue microchirurgicale par lambeau libre perforant aux dépens de l'artère epigastrique inférieure profonde (DIEP) : techniques classique et mini-invasive extra-péritonéale par laparoscopie.

Perforator free flaps allow breast reconstructions « like with like ¼ with skin and fat, excluding mammary gland, with a low morbidity. Those autologous reconstructions prevent material associated infections, capsular contracture and implant replacements, associated to breast reconstructions including implants. DIEP flap was described in 1994 to reduce the morbidity faced with TRAM flaps harvest. It only includes sub-umbilical skin and deep epigastric vessels. Deep inferior epigastric vessels harvest requires rectus abdominis muscle sheet opening and traction on rectus muscles, both associated with increased risks of abdominal bulges. Since 2014, we developed a minimally invasive DIEP harvest by totally extra-peritoneal laparoscopic dissection of epigastric vessels with a 70% reduction of aponeurosis opening and avoiding traction on rectus' motor nerves. We report both classic and minimally invasive DIEP harvest techniques. Bresat reconstructions by DIEP require that the ombilicus can be transposed and are indicated for all patients with need for skin inset, particularly secondary breast reconstructions. The reconstructed breast as a volume that follows patients weight variations and allows for improved quality of life on a long term. Its minimally invasive totally extra peritoneal harvest by laparoscopy, with or without robotic assistance, offers a reduced morbidity and might allows for reduced risks of abdominal wall weakness on a long-term.

[Transposition of the cephalic vein in free flap breast reconstruction: Technical note]. / Déroutage de la veine céphalique dans la reconstruction mammaire par lambeaux libres : note technique.

Free flaps have become a reliable practice for breast reconstruction. However, the venous congestion is still the most frequent reason of flap failure. It is due to bad quality of the internal mammary veins, a preferential superficial venous outflow of the flap or due to venous thrombosis. The transposition of the cephalic vein could useful in some cases. We describe the surgical technique and suggest an intraoperative algorithm. Seventeen patients (15 DIEP and 2 PAP) were included. Twenty nine point four percent had an unusable internal mammary vein, 23.5% a preferential superficial venous outflow and 47.1% a venous thrombosis. The length of the cephalic vein dissected varied from 15 to 25cm. The mean time of dissection was 39min. There was no flap failure after cephalic vein transposition. The sequelae were one or two scars on the arm without any functional morbidity. The transposition of the cephalic vein is a reliable, less morbid alternative in case of bad quality internal mammary vein with a good quality internal mammary artery, in case of an additional venous outflow necessity or in case of venous thrombosis.

Medicinal leech therapy and Aeromonas spp. infection.

While the use of medicinal leech therapy (MLT) in reconstructive and orthopaedic surgery is widely described, post-operative complications related to leeches remain a major concern. Aeromonas spp. strains are involved in the majority of reported cases. As surgical success rate is directly impacted, an adapted antibiotic prophylaxis should be instituted in order to minimize these complications. We assessed pharmaceutical process, microbiological control and related infections in order to provide data and choose the appropriate antibiotherapy for patients requiring MLT. We report a clinical and microbiological study over a 24-month period. Clinical data were collected from patients' database, and microbiological analysis both on leeches' tank water and crushed leeches were performed to characterize isolated strains and their susceptibility to antibiotics. A total of 595 leeches were used to treat 28 patients (12 in plastic surgery and 16 in orthopaedic surgery), and three documented cases of post-operative infections were reported. Aeromonas spp. isolates yielded from 62 % of analyzed batches (75 % of Aeromonas veronii). Eighteen Aeromonas spp. isolates yielded from 23 water samples and three crushed leeches. Isolates were similar in tank and crushed leeches. Strains were susceptible to fluoroquinolones, sulfamethoxazole/trimethoprim, aminosides, and third-generation cephalosporins but resistant to amoxicillin/clavulanic acid and second-generation cephalosporins. According to collected data, routine tank water microbiological analyses are mandatory in order to identify leeches' batches containing resistant strains and to discard them. In this context, the surgeon is able to select an appropriated antibiotic prophylaxis in order to avoid MLT associated serious post-operative complications.

[Breast reconstruction with Profunda Artery Perforator flap in lithotomy position. Surgical technique]. / Reconstruction mammaire par Profunda Artery Perforator flap prélevé en position gynécologique. Technique chirurgicale.

Autologous breast reconstruction provides great cosmetic, functional and sustainable incomes. Various flaps have been described in autologous breast reconstruction, Deep Inferior Epigastric Perforator flap (DIEP) being the most frequent. For patients with a non-sufficient abdomen for a DIEP based breast reconstruction, the Profunda Artery Perforator Flap (PAP), based on profunda arteris perforators, is a current trend, but few publications detailed the flap harvest. Comparing with a TUG flap, the morbidity linked to the muscle harvest is decreased. Usually the dissection is done in prone or in "frog leg" position. The aim is to describe a technical option: we propose a different position, with a harvest of the PAP in lithotomy position. It offers additional comfort and security for the surgeon and decreases the operative time. The pedicle had an average of 7cm in length; the artery diameter was 2.2mm and the vein 2.5mm. The cosmetic incomes are very good six months postoperative.

[Breast reconstruction with profunda artery perforator flap: A prospective study of 30 consecutive cases]. / Reconstruction mammaire par profunda artery perforator flap : étude prospective des 30 premiers cas consécutifs.

INTRODUCTION: Many flaps have been described in autologous breast reconstruction, the most common being the deep inferior epigastric perforator (DIEP) flap. This flap cannot be harvested in a certain range of patients. The profunda artery perforator (PAP) flap, based on perforators from profunda femoral artery, is therefore a good option. OBJECTIVE: The goal was to highlight technical tips, particularities, and complications of our series of the 30 first PAP flaps for breast reconstruction in our department. PATIENTS AND METHOD: We did a prospective study of all PAP flaps for breast reconstruction between November 2014 and October 2015. Thirty patients were included. We used 2 different types of skin design: classical or with vertical extension. The following parameters were recorded: pedicle length, flap weight, surgery duration, complications on donor or recipient site and type of recipient vessels. RESULTS: Seventy-seven percent of the cases were delayed breast reconstruction, 23% were immediate. Twenty-five flaps were with classical skin design, and 5 with vertical extension. Mean flap weight was 301g (195-700g). Mean pedicle length was 9.88cm (8.2-12.5cm). Internal mammary vessels were the recipient vessels for 90% of the patients, versus 10% for circumflex scapular vessels. Mean surgery duration was 328min (195-610min). We had two total flap failures. The complications on the donor-site were 2 seroma, and 4 late healing scars. No lymphoedema occurred. CONCLUSION: PAP flap is a good option when abdominal flap harvesting is not possible. The donor-site is well tolerated, with low morbidity. The indication is for patients with small to medium breast volume.

Using free flaps for reconstruction during infections by mucormycosis: A case report and a structured review of the literature.

BACKGROUND: Mucormycosis is a very rare infection caused by fungi from the order Mucorales, it rarely involves the skin. We report a case of necrotizing fasciitis of the upper limb which required an aggressive surgical debridement, antifungal therapy and coverage of the defect with a free DIEP flap, a review of the literature was also done regarding indications of reconstruction with free flaps. CASE PRESENTATION: Here we present a case of cutaneous mucormycosis of the right upper limb in a 49-year-old immunocompetent woman after having an open fracture associated with massive contamination during a motor vehicle collision. In early postoperative period, she had multiple skin necrotic lesions. Serial surgical debridements were performed and ended up with interscapular-thoracic amputation associated with a total mastectomy. Following diagnosis confirmation of mucormycosis infection, the patient was started on antifungal therapy for several months. After disease control, the large defect was successfully covered by a DIEP flap. CONCLUSION: Cutaneous mucormycosis requires antifungal therapy along with aggressive debridement, reconstruction by a free flap seems to be a good solution to cover these large defects.

A new strategy for prophylactic surgery in BRCA women: Combined mastectomy and laparoscopic salpingo-oophorectomy with immediate reconstruction by double DIEP flap.

BACKGROUND: Prophylactic surgery remains the most effective modality for reducing both breast and ovarian cancer rate in woman at high risk, such as BRCA1 or BRCA2. Autologous breast reconstruction with bilateral deep inferior epigastric perforator (DIEP) flap allows predictable and durable results. However, existing two-step approach separating salpingo-oophorectomy and reconstruction could even make DIEP flap impossible, or make insufflation more difficult during laparoscopy. Other authors described one-step procedure but with open laparotomy. The goal of this study was to verify the feasibility of a simultaneous procedure, including laparoscopic salpingo-oophorectomy. METHODS: We included BRCA mutation careers scheduled for simultaneous laparoscopic salpingo-oophorectomy, and bilateral breast reconstruction with DIEP flaps. The first step of the procedure was laparoscopic salpingo-oophorectomy and ports had to be strategically placed to avoid interference with the following procedure. The second step was bilateral breast reconstruction with DIEP flaps. We reviewed medical charts. Surgical procedure was analyzed for duration, revisions and surgical complications. RESULTS: During 1-year period, eight patients agreed to a simultaneous procedure. All of them were BRCA positive, mean age was 38.3years (range, 39-50), and mean BMI was 28.3kg/m(2) (range, 21-33). The mean duration of the entire procedure was 524minutes (range, 405-630) and the mean hospital stay 9.2 days (range, 8-14). There was 100% flap survival. No abdominal wall dehiscence occurred. CONCLUSION: One-step procedure for prophylactic surgery of ovarian and breast hereditary malignancies is feasible. First salpingo-oophorectomy with open laparoscopy then bilateral immediate or delayed breast reconstruction with DIEP flaps can be performed.

[Poly Implant Prothèse (PIP®) incidence of complications in breast reconstructive surgery: A retrospective comparative analysis]. / Poly Implant Prothèse (PIP®) et incidence des complications en reconstruction mammaire: une étude rétrospective contrôlée.

INTRODUCTION: On 29 March 2010, the Poly Implant Prothèse (PIP(®)) breast prosthesis was withdrawn from the market by the ANSM. In this study we review our experience with PIP(®) implants in breast reconstruction. We compare our complications with other types of breast implants used during the same period at our institution. PATIENTS AND METHOD: This is a retrospective study conducted at the Hospital René Huguenin of the Institut Curie (Paris, France). It includes 327 prostheses, from 268 patients who underwent surgery for breast reconstruction between February 2008 and February 2012: 69 PIP(®) (Group 1), 82 Mentor(®) (Group 2) and 179 Allergan(®) (Group 3). The objective of the study was to compare the rates of early and late complications for each prosthesis. Our results are compared with the current literature. RESULTS: With regard to the rate of early complications (hematoma, infection, seroma, wound dehiscence), no difference was observed between the three groups (P not significant). However, the study found that 100% of the 13 PIP(®) implants with early complications required surgical revision. There were too few late complications (capsular contracture, prosthetic rupture) in our cohort to allow statistical comparison between the three groups (P not significant). We compare our results with the current literature. CONCLUSION: This study highlights the lack of significant difference in the occurrence of early adverse events between the three groups of implants. This may explain the time taken for surgeons to become aware there was a problem with the PIP(®) implants. The low rate of late complications in our series does not allow statistical analysis between the three groups of implants.

[Setting of a breast autologous microsurgical reconstructive surgery evolution in 20 years and review of 1138 cases]. / Mise en place d'une activité de reconstruction microchirurgicale du sein par tissus autologues. Évolution sur 20 ans et revue de 1138 cas.

UNLABELLED: The authors conducted a retrospective study of breast reconstruction with DIEP free flap between 1994 and 2014 by a single team. MATERIAL AND METHOD: A retrospective analysis of all operative charts and hospitalization was conducted for the period from 1994 to 2014. The number of cases per year, the complication rate of the donor site and recipient site, and surgery time were recorded. Sequence analysis was conducted to determine the elements that have enabled to implement this technique reliably and effects of the learning curve. The series was split into two periods (1994/2011 and 2012/2014) corresponding to two different hospitals with the same team. RESULTS: The total number of shreds of 1138 between November 1994 and December 2014 respectively with 477 and 661 the period 1994/2011 to 2012/2014 period. The failure rate increased from 8% to 2.2%. CONCLUSION: The establishment of units mainly dedicated to microsurgical reconstruction can offer the DIEP technique reliably and reproducibly.

Anaesthesia and intensive care management of face transplantation.

The face-grafting techniques are innovative and highly complex, requiring well-defined organization of all the teams involved. Subsequent to the first report in France in 2005, there have been 17 facial allograft transplantations performed worldwide. We describe anaesthesia and postoperative management, and the problems encountered, during the course of seven facial composite tissue grafts performed between 2007 and 2011 in our hospital. The reasons for transplantation were ballistic trauma in four patients, extensive neurofibromatosis in two patients, and severe burns in one patient. Anaesthesia for this long procedure involves advanced planning for airway management, vascular access, technique of anaesthesia, and fluid management. Preparation and grafting phases were highly haemorrhagic (>one blood volume), requiring massive transfusion. Median (range) volumes given for packed red cell (PRC) and fresh-frozen plasma (FFP) were 64.2 ml kg(-1) (35.5-227.5) and 46.2 ml kg(-1) (6.3-173.7), respectively. Blood loss quantification was difficult because of diffuse bleeding to the drapes. The management of patients with neurofibromatosis or burns involving the whole face was more difficult and haemorrhagic than the patients with lower face transplantation. Average surgical duration was 19.1 h (15-28 h). Postoperative severe graft oedema was present in most patients. Most patients encountered complications in ICU, such as renal insufficiency, acute respiratory distress syndrome, and jugular thrombosis. Opportunistic bacterial infections were a feature during the postoperative period in these highly immunosuppressed patients.

[Fibrin sealant significantly decrease postoperative drainage in breast reconstruction by deep inferior epigastric perforator (DIEP) flap]. / Diminution significative des volumes de drainage postopératoires en reconstruction mammaire différée par lambeau libre DIEP par utilisation de colle de fibrine.

PURPOSE: Serosanguinous drainage after breast reconstruction by deep inferior epigastric perforator (DIEP) flap constitute with the microsurgical monitoring, the main limiting factors for patient discharge. Fibrin sealant has already been studied to reduce post breast surgery drainage. The authors are presenting their experience in secondary breast reconstruction by DIEP flap with the use of sprayed fibrin sealant. PATIENTS AND METHODS: Twenty-one female patients aged 28 to 63 years old who underwent secondary breast reconstruction after mastectomy for cancer between October 2004 and June 2007 have been reviewed. These patients were separated into two groups. In group 1, patients (n=9) received two drains placed under the flap and in the axillary area. In group 2, (n=12) the DIEP flaps and thoracic areas were sprayed with fibrin sealant (Tissucol(®)) before the two drains inset. RESULTS: No adverse effect were reported, with a 36-month median follow-up. Drainages volumes or durations were not correlated to the patients' Body Mass Index (BMI). Lower drained volumes were collected from the thoracic region (372ml versus 629mL) and thoracic drains were removed earlier (5.5 days versus 6.9 days) in group 2. The length of stay was also significantly reduced after fibrin sealant use (5.5 days versus 7.22 days with P=0.0305 by log rank test). CONCLUSION: This study is a rare clinical one on fibrin sealant use to decrease postoperative drainage in breast reconstruction by DIEP flap. Fibrin sealant significantly decreased the postoperative drainage volume and duration.

Feasibility, reproducibility, risks and benefits of face transplantation: a prospective study of outcomes.

Composite tissue allotransplantations can be indicated when autologous transfers fail to restore human appearance. We report the reproducibility, difficulties, serious adverse events and outcomes of our patients. Five patients were included in a registered clinical research protocol after thorough screenings assessed by an independent expert committee systematically discussing the alternative options. One patient suffered from plexiform neurofibromas, two from third degree burns and two from gunshot injuries. They were included on a national waiting list with a dedicated face procurement procedure. Transplants were harvested from heart beating brain-dead donors before other tissues and organs. Induction immunosuppressive therapy included antithymocyte globulins, steroids, mycophenolate mophetil and tacrolimus. Maintenance therapy included the last three ones associated with extracorporeal-photopheresis. Four patients were transplanted with 7- to 38-month follow-up. One could not due to multiple panel reactive antibodies after 18 months on waiting list. Acute cellular rejections were controlled by conventional treatment. Opportunistic infections affected all patients and lead one patient to die two month after the transplantation. Voluntary facial activity appeared from 3 to 5 month. Face transplantation has been reproducible under conventional immunosuppression. Major improvements in facial aesthetic and function allowed patients to recover social relations and improved their quality of life.

[A cost analysis of DIEP flap in breast reconstruction]. / Analyse médico-économique du lambeau libre de DIEP en reconstruction mammaire.

BACKGROUND: We postulate that the absence of a CPT code for DIEP (deep inferior epigastric perforator) free flap in breast reconstruction is in part responsible for the delayed adoption of this modern technique in France. In order to provide data to our regulating health agency, we determined the cost of this technique compared to a gold standard. We performed a cost-identification study, comparing costs of DIEP free flap versus latissimus dorsi pedicled flap with implant (LD+I) in secondary breast reconstruction following irradiation. METHODS: Over a 12-month period, direct medical and non-medical costs as well as indirect costs were recorded in both groups (DIEP and LD+I). RESULTS: In an academic department funded by the national health system, total cost of a secondary breast reconstruction by DIEP free flap was 10,671 ± 3005€ (n=57) versus 8218 ± 2049€ (n=18) for the LD+I group (P<0.05). Mean OR occupation time was 390 ± 64minutes for DIEP versus 283 ± 44minutes for LD+I (P<0.05). Mean hospital stay was 6 ± 2 days for DIEP versus 5 ± 2 days for LD+I (P>0.05). CONCLUSION: DIEP free flap technique offers a long lasting breast reconstruction at an reasonable expense compared to the LD+I (+22%). Furthermore, in an academic department, collaboration of two microsurgeons during DIEP flaps allows OR times to drop significantly and become competitive with LD+I.

Clinical applications in an emergency unit of reconstructive surgery: four clinical cases]. / Intérêt de l'angio-TDM dans la chirurgie des lambeaux perforants. Applications dans une unité de chirurgie plastique et reconstructrice. A propos de quatre cas cliniques.

Our experience of the deep inferior epigastric artery perforator flap has led us to perform systematically an abdominal CT-scan for the pretherapeutic checking. This exam gives us a precise vascular mapping of musculocutaneous and septocutaneous perforators artery of the flap, may enable a better orientation in the dissection and reduce the surgery time. We have enlarged the indication of this exam to the members flaps who needs the dissection of a musculocutaneous or a septocutaneous perforators vessels: Nakajima's et al. classification [1]. The mapping of perforating vessels on 3D reconstruction pictures helps us to planify the vascular cutaneous autologous grafts.
