Here is a video that shows the harvest of a thin profunda artery perforator flap from the left thigh. In conjunction with preoperative computed tomography angiography, measurement of the morphology of the perforators and their branches, the pedicle length, and the vertical locations of the two branches from the ischial tuberosity are performed. A handheld doppler is used to confirm the location of both branches. As a result of the authors' results, preoperative computed tomography angiography is a valuable way of obtaining detailed anatomical information such as the shape of perforators, their path through the septum or muscle above the deep fascia, as well as the thickness of the skin. It is important to know that computed tomographic angiography is an excellent means of making an assessment of the entire vascular anatomy of the leg, and it results in making an informed decision about the choice of flaps, based on the patient's anatomy and the characteristics of the defect.

Vertical sleeve gastrectomy (VSG) is a type of bariatric surgery that is accepted as the simplest but most efficient surgical modality to treat morbid obesity. A mouse model of VSG has been widely utilized to investigate the underlying mechanisms of VSG. There are numerous microsurgical techniques for VSG in mice, and the authors report herein a modified technique with 2 disposable micro-clamps to simplify the surgery. The key aspects of the modification are to use the micro-clamps as non-crushing tissue clamps for anastomosis as well as vascular clamps for hemostasis. Mean body weight at postoperative week 1 was 24.1 grams, which is equivalent to a 16.1% loss of original body weight, and there was no mortality after antrum preservation VSG. This simplified surgical technique will best serve as a tool to investigate either the underlying mechanisms of VSG or the intrinsic change to the stomach after VSG.

One of the aims of several reconstructive surgical procedures is to achieve a patent microvascular anastomosis. Developing clinical competency in this specialized skill requires intensive training on live animal models as a first step. The early training stage of microvascular anastomosis can be stressful for novices. This is because the rat vessels used in such training courses are usually too small and fragile for novices to maintain the vascular lumen in an optimal fashion. Throughout this paper, the authors discuss the use of a silicone tube to provide structural support to vessels throughout the entire precarious suturing process. Using this modified version of the conventional microvascular anastomosis technique may facilitate initial skill acquisition in the rat model.

Lymphaticovenular anastomosis (LVA) and vascularized lymph node transfer (VLNT) are established lymphedema treatments. However, LVA is only effective for early disease and VLNT can cause donor-site lymphedema and contour deformity. Vascularized lymph vessel transfer (VLVT) is free of these limitations. In the video, the authors described their experience of a new VLVT technique.
