    Abstract Background: Severely burned patients suffer from both coagulopathy and hypothermia, with a lack of international consensus and appropriate treatment guidelines. This study examines recent developments and trends in coagulation and temperature management in European burn centers.
    Methods: A survey was sent to burn centers in Switzerland, Austria and Germany in 2016 and again in 2021. The analysis was performed using descriptive statistics, with categorical data reported in absolute numbers (n) and percentages (%) and numerical data reported as mean and standard deviation.
    Results: The rate of completed questionnaires was 84 % (16 of 19 questionnaires) in 2016 and 91 % (21 of 22 questionnaires) in 2021. The number of global coagulation tests performed has decreased over the observation period in favor of single factor determination and bed-side point-of-care coagulation tests. This has also led to increased administration of single factor concentrates in therapy. Although many centers had a defined treatment protocol for hypothermia in 2016, coverage increased such that in 2021 all centers surveyed had such a protocol. The body temperature was measured more consistently in 2021; thus, hypothermia was more actively sought, detected and treated.
    Conclusion: A point-of-care guided, factor-based coagulation management and the maintenance of normothermia have gained importance in the care of burn patients in recent years.

    Abstract Introduction: Identification of patent lymphatic vessels without fibrosis and with high flow is difficult but crucial in the preoperative planning of lymphaticovenous anastomosis (LVA). Lymphatic vessels on the operating field cannot always be visualized preoperatively because of the anatomical and physiological characteristics of lymphedema tissue. The purposes of this study were to demonstrate our clinical experience in identifying indocyanine green (ICG)-negative lymphatics intraoperatively and to emphasize the therapeutic potential of performing anastomoses with ICG-negative lymphatics.
    Methods: Indocyanine green-positive lymphatic ducts were marked preoperatively in 5 patients with lower extremity lymphedema; moreover, if ICG-negative lymphatics were identified during surgery, they were used for additional LVA thus implementing multiple anastomoses in one surgical setting.
    Results: In total, 33 LVAs were performed in 5 patients with lower extremity lymphedema, of which 11 LVAs were implemented with ICG-negative lymphatics. Immediately after the anastomosis, a strong lymphatic drainage could be appreciated in all cases. Six months postoperatively patients reported a subjective decrease in limb circumference and pressure sensation.
    Conclusions: We believe that ICG-negative lymphatics found intraoperatively should be evaluated for additional LVAs in order to maximize drainage effect and might provide better outcomes.

    Abstract Background: Skin and soft-tissue defects around the knee are common and their reconstruction is still challenging and argued. Thin, pliable and well-vascularized tissues are required in order to restore the aesthetic appearance of the knee and facilitate joint function. Historically local muscle flaps were employed for the upper third of the lower limb reconstruction; however, since their introduction, different perforator flaps have been proposed for this purpose. The aim of this report is to share our clinical experience with the pedicled lower medial thigh perforator (p-LMT) flap for the reconstruction of skin and soft tissue defects around the knee.
    Patients and methods: Between August 2013 and July 20, 2018, patients underwent pedicled LMT propeller flap reconstruction for defects around the knee. The subunits of the defects were the suprapatellar, the infrapatellar and patellar area and in two cases a full around the knee defect was reported. Cause of defects included trauma (13), tumor (4) and infection after knee operation (3) and defect sizes ranged from 4 × 3 cm
    Results: Flap sizes ranged from 4 × 9 cm
    Conclusions: Fasciocutaneous flaps are currently the first reconstructive option for the soft tissue defects around the knee. The p-LMT flap reconstruction in this case series achieved good aesthetic and functional outcomes and this flap may be a valuable option for the reconstruction of the small to medium soft tissue defects around the knee.

    Abstract Introduction: Groin defects with exposed complex structures are challenging to treat. Perforator flaps provide a contemporary alternative to established muscle flaps to cover all varieties of groin defects, with minimum donor site morbidity, less postoperative pain, and faster rehabilitation. In this retrospective single-center analysis, we aimed to show that pedicled perforator flaps are a valid option for groin defect reconstruction. We present three different pedicled perforator flaps and discuss the flap selection process and their distinct advantages and disadvantages.
    Methods: A series of 54 consecutive cases of patients with groin defects were allocated into three different treatment groups. Reconstruction was performed utilizing the anterolateral thigh (ALT) flap, the pedicled posteromedial thigh (PMT) perforator flap, and the vertical deep inferior epigastric artery perforator (vDIEP) flap.
    Results: All 54 flaps survived. Early complications included one hematoma (vDIEP) and two infections (ALT and PMT). Delayed complications occurred in three recipient-site seromas (ALT, PMT, and vDIEP), one donor-site seroma (vDIEP), and one flap dehiscence (ALT). All flaps provided stable coverage during 3-12 months of follow-up.
    Conclusion: We propose pedicled perforator flaps to be a safe and reliable option for groin defect reconstruction. The pedicled PMT flap should be the first choice if the profunda femoris artery and its perforators are available. The ALT flap can be applied as a second choice, especially if complex groin defect with exposed vascular prosthesis reconstruction is needed because of its versatile expansion options, for example, as a chimeric flap using a portion of the vastus lateralis muscle. In cases where the profunda femoris artery is not available, the vDIEP flap should be the preferred method.

    Abstract Introduction: Lymphedema is a chronic condition caused by the obstruction or impairment of lymphatic fluid transport resulting in irreversible skin fibrosis. Besides conservative therapy, surgical techniques for lymphedema including liposuction, lymphatico-lymphatic bypass, lymphovenous anastomosis (LVA), and vascularized lymph node transfer (VLNT) are options with increasing popularity in the recent past. In our review, we investigated the efficacy of LVA for the treatment of lymphedema. Both objective and subjective outcomes of surgical treatment were evaluated.
    Methods: Studies were identified through systematic review in PubMed database up to September 2016. Only original Articles which exclusively performed LVA for lymphedema treatment were included. Our primary endpoint was the objective of a subjective postoperative lymphedema reduction.
    Results: A total of 293 titles were identified, out of which 18 studies including 939 patients were deemed eligible. The studies included in this review describe significant variations in surgical techniques, number of anastomoses and supplementary interventions. All studies reported objective reductions in circumference measurements. Subjective symptom relief was found in 50-100% of the patients as well as a reduction in the number of cellulitis episodes in all investigated cases.
    Conclusion: Although the studies included in this review showed great heterogeneity, LVA surgery revealed both objective and subjective improvements in most patients.

    Abstract Background: Allogeneic blood transfusions are common in the treatment of severely burned patients as surgery may lead to major blood loss. However, transfusions are associated with a number of adverse events. Therefore, the purpose of our study was to investigate the impact of allogeneic blood transfusions on clinical outcomes in severely burned patients.
    Methods: This retrospective study included all adult patients admitted to the burn center of the University Hospital Zurich between January 2004 and December 2014, with burn injuries greater than 10% of total body surface area and receiving both surgical and intensive care treatment. Primary Endpoints were infectious or thromboembolic complications and mortality and secondary endpoints were length of hospital and ICU stay. Simple and multivariable logistic and linear regression models, adjusted for injury severity and confounders, were applied.
    Results: 413 patients met inclusion criteria of which 212 patients (51%) received allogenic blood products. After adjustment for injury severity and confounders, red blood cell transfusion was independently associated with wound infection (OR 13.5, 95% CI 1.7-107, p = 0.014), sepsis (OR 8.3, 4.2-16.3; p < 0.001), pneumonia (OR 4.7, 2.2-10.0; p < 0.001), thrombosis (OR 3.0, 1.2-7.4; p = 0.015), central line infection (OR 34.7, 4.6-260; p = 0.001) and a longer ICU and hospital stay (difference 17.7, CI 12.1-23.4, p < 0.001 and 22.0, 15.8-28.2, p < 0.001, respectively). Fresh frozen plasma transfusion was independently associated with a longer ICU and hospital stay (difference 13.7, 95% CI 5.5-21.8, p = 0.001 and 13.5, 4.6-22.5, p = 0.003, respectively). Platelet transfusion was independently associated with systemic inflammatory response syndrome (OR 4.5, 1.3-15.5; p = 0.018) and mortality (OR 5.8, 2.1-16.0; p = 0.001).
    Conclusion: Transfusion of allogeneic blood products is associated with an increased infection rate and thromboembolic morbidity and a longer hospital stay in severely burned patients.

    Abstract Introduction: Lymphedema remains a challenging clinical problem. A new field of lymphatic surgery using micro and super microsurgery techniques is a rapidly advancing field aimed to treat recalcitrant cases. The objective of this study was to evaluate outcomes and complications of vascularized lymph node transfer (VLNT). Several early preliminary studies have reported promising outcomes, but they are limited by small numbers, short follow-up, and are inconsistent in addressing the origin and recipient site of the transferred lymph nodes as well as the donor site morbidity.
    Methods: A review of literature was conducted using PubMed-MEDLINE, EMBASE for key words vascularized lymph node transfer (also autologous, lymph node transplant). Only human studies were included.
    Results: A total 24 studies encompassing 271 vascularized lymph node transfers were included. The inguinal nodes were the most commonly used donor site followed by the lateral thoracic lymph nodes. The lateral thoracic lymph nodes were the least effective and had the highest complication rates (27.5%) compared to other lymph node donor sites (inguinal: 10.3% and supraclavicular: 5.6%). Upper extremity lymphedema responded better compared to lower extremity (74.2 vs. 53.2%), but there was no difference in placing the lymph nodes more proximally versus distally on the extremity (proximal: 76.9% vs. distal: 80.4%).
    Conclusion: Vascularized lymph node transfer for lymphedema treatment is a promising operative technique showing beneficial results in early but also in advanced stage lymphedema. This physiologic surgical procedure should be included in a modern reconstructive concept for lymphedema treatment. © 2016 Wiley Periodicals, Inc. Microsurgery 38:222-229, 2018.
