RESUMEN

BACKGROUND: Breast cancer is the most frequent cancer among women and is responsible for the highest number of cancer-related deaths. Approximately 40% of the patients with breast cancer will undergo a mastectomy. Breast amputation is a lifesaving but mutilating procedure. Therefore a good quality of life and a good cosmetic outcome is mandatory after breast cancer treatment. Reconstructive breast surgery aims to recreate a natural looking breast that is warm, soft and feels natural. The chosen reconstruction technique depends on the physiognomy of the patient, technical skills of the surgeon and most important the expectations of the patient. RESULTS: The idea of 'like-by-like' replacement refers to reconstruction of a natural-looking, warm, soft and ptotic breast that matches the contralateral side. Autologous breast-reconstruction matches these expectations. Autologous breast reconstructions with free flaps evolved from prolonged and laborious procedures with only limited free flaps available, to routine surgeries with a widespread availability of flaps to use. The first publication of free tissue transfer for breast reconstruction was in 1976 by Fujino. Two years later Holmström was the first to use the abdominal pannus for breast reconstruction. Over the next four decades multiple free flaps have been described. The possible options for donor site are the abdomen, the gluteal region, the thigh and the lower back. During this evolution the reduction of donor site morbidity became more important. CONCLUSION: Present article gives an overview of the evolution of free tissue transfer in breast reconstruction, highlighting the most important milestones.

RESUMEN

Background: Age-related changes to the dorsum of the hand present as dyschromia, soft-tissue atrophy, and volume loss, resulting in wrinkles and prominent deep structures. Volume augmentation by means of autologous fat transfer (AFT) is one of the options to rejuvenate the hand; theoretically, autologous fat is the ideal filler because of durability and biocompatibility. Objective: This systematic review aims to summarize and describe the current evidence on the technique, effectiveness, and safety of AFT in hand rejuvenation. Methods: Three major databases, PubMed, Embase, and Web of Science, were systematically searched up to November 2020 for studies reporting on AFT and hand rejuvenation. Results: A total of 10 articles were included, reporting on a total of 320 patients treated by AFT to improve the aesthetic appearance of the dorsum of the hand. Some degree of postoperative oedema was present in nearly all patients. Other complications were infection (0.67%), cysts/irregularities (1.3%), temporary dysesthesia (5.3%), and ecchymosis (7%). There were no major complications. Of all patients, 97.6% self-reported to be satisfied with the result. Conclusions: Overall, by combining the current evidence, AFT is considered a promising and safe technique to rejuvenate the aging hand with very high patient satisfaction. Future research, using validated patient questionnaires, objective volumetric measurements, and longer follow-up, is needed to confirm these results. Level of Evidence: 3.

RESUMEN

OBJECTIVE: Breast reconstructions with perforator flaps from the lower abdomen, commonly known as Deep Inferior Epigastric artery Perforator flap (DIEP-flap), have become the golden standard for autologous breast reconstruction after breast amputation. During this surgical procedure multiple challenging steps are encountered such as the selection of a suitable perforator that provides sufficient blood supply for the flap, surgical dissection of the chosen perforator, determination of perfusion area of the chosen perforator, microsurgical anastomosis, flap inset and shaping the flap into a breast. The current gold standard for perforator mapping is Computed Tomography Angiography (CTA). However, this is a relatively expensive imaging modality that requires intravenous contrast injection and exposes patients to ionizing radiation. More recently, Dynamic Infrared Thermography (DIRT) has been proposed as an alternative imaging modality for perforator identification. DIRT appears to be an ideal alternative technique not only for the identification of the dominant perforators, but also for the mapping of the individual influence of each perforator on the flap perfusion, to monitor integrity of the perforator after dissection and to monitor the patency of the pedicle of the free flap after the anastomosis, during flap inset and flap shaping. STUDY DESIGN: In this clinical study we present the results of the use of DIRT in 33 DIEP-flaps in 21 patients after mastectomy. The same standardized measurement set-up was used for all the flaps in the pre-, intra- and postoperative period. RESULTS: In the pre-operative period DIRT confirmed the location of the 69 perforators shown on the CTA. In the intra-operative period the rate and pattern of rewarming was successfully observed. One perforator was severely damaged during dissection and the DIEP flap was converted to a Muscle Sparing free Transverse Rectus Abdominis Muscle (TRAM) flap, after viability check of the flap by DIRT. DIRT diagnosed one kinking of the pedicle after microsurgical anastomosis. Two flaps were monitored successfully post-operatively. All 33 breast reconstructions were with good outcome. CONCLUSION: The use of DIRT with our standardized measurement setup is a useful, non-invasive tool during breast reconstructions with free DIEP-flaps in all the phases of the reconstruction (pre-, intra- and post-operative). This study confirms that DIRT with the standardized measurement setup provides information on perforator location, blood supply and patency of the anastomosis without interference with the operating surgeon.

RESUMEN

Background: Ewing's sarcoma is the second most common primary malignant bone tumour in children. Depending on localisation and extent, massive bone defects remain when curative surgery is performed. Whereas in the past, limb amputation was often unavoidable to obtain curative resection, nowadays different limb saving reconstructive options are available.Case report: We report the successful reconstruction of a massive femur defect with a free vascularised fibular graft (FVFG) after Ewing's sarcoma resection in a four-year-old girl. Both the age of the patient and the extensive graft hypertrophy makes this case exceptional.Conclusion: Femur reconstruction with a FVFG is a rarely performed and complex procedure in young children. It is an excellent reconstructive technique for large long bone defects, which can avoid limb amputation without compromising oncologic outcome.

RESUMEN

Breast reconstruction with an autologous free Deep Inferior Epigastric Perforator (DIEP) flap is one of the preferred options following mastectomy. A challenging step in this procedure is the selection of a suitable perforator that provides sufficient blood supply for the flap. The current golden standard for perforator mapping is computed tomography angiography (CTA). However, this is a relatively expensive imaging modality that requires intravenous contrast injection and exposes patients to ionizing radiation. More recently, dynamic infrared thermography (DIRT) has been proposed as an alternative imaging modality for perforator identification. DIRT appears to be an ideal alternative technique not only for the identification of the dominant perforators, but also for the mapping of the individual influence of each perforator on the flap perfusion. Multiple studies have been performed with the use of DIRT, unfortunately without standardisation of the measurement set-up. In this technical note we propose a standardised and reproducible measurement set-up for the use of DIRT during breast reconstructions with a free DIEP flap. This set-up can be used pre-, intra- and postoperatively. A standardised measurement set-up will improve the quality of measured data and ensure reproducibility.

RESUMEN

PURPOSE: One of the options to repair a ruptured distal biceps tendon to the radial tuberosity is by means of a transosseous cortical button. Although excellent functional outcomes have been reported, no studies have been performed to quantify the effect of the transosseous fixation technique on the radius. Our study evaluated the clinical outcome and radiological outcome of this technique. The main goal of this study was to evaluate the radiographic evolution of the bone tunnel in the radius. METHODS: Patients with an acute distal biceps tendon rupture treated with a transosseous cortical button were invited to take part in the study. Fourteen patients were included in the final analysis. All patients were evaluated both clinically and by computed tomography scanning of the proximal radius after a minimum follow-up of 2 years. Outcomes were recorded using the visual analog scale score for pain, the Mayo Elbow Performance Score, and Disabilities of the Arm, Shoulder, and Hand scores. Bone tunnel volume was measured with semiautomated computed tomography segmentation using image-processing software. RESULTS: There were no failures of fixation in the patient group examined. Elbow mobility, arm, and forearm circumference were symmetric for all patients. Average visual analog scale for pain was less than 2. Mean Disabilities of the Arm, Shoulder, and Hand score and Mayo Elbow Performance Score were 2.3 and 97.6, respectively. Computed tomography images showed an average closure of the radial bony tunnel of 64% of the initial volume. CONCLUSIONS: Biceps tendon repair with cortical button fixation only shows partial tunnel closure. This could reduce the risk of potential complications due to osteolysis, such as radius fracture or hardware failure. Functional results were excellent and comparable to other fixation methods. The role of interference screws in transosseous cortical button techniques to strengthen the repair and to avoid osteolysis may therefore be questioned. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
