Large defects after skin malignant tumors resection were difficult to repair. We introduced a partition concept, in which the large defects were divided into several subunits, and each subunit was repaired by a certain pedicled flap to achieve a complete coverage.Between May 2012 and Oct 2016, 8 patients with skin malignant tumors underwent radical resection. Prior to surgery, the dimension of ...
Objective: The reverse radial forearm flap has been used for soft-tissue hand defect surgical procedures worldwide. One of the major drawbacks of this flap, however, is donor site morbidity, as the donor site is closed with a skin graft. Problems with skin graft donor areas include adhesion, contracture, and wound-healing complications. In this study, only the adipofascial component of a revers...
objective(s): the aim of this study is to determine the effects of progesterone treatment on the survival of random skin flaps. materials and methods: mcfarlane flaps were established and 40 male rats were randomly assigned to the progesterone-treated as the test group or normal saline-treated as the control group. progesterone or normal saline (10 mg/kg) was administered intraperitoneally once...
Medial Sural Artery Perforator Flap: Using the Superficial Venous System to Minimize Flap Congestion
813 free perforator flap surgery and always have a second option in mind in case of flap failure. Further, a sufficient understanding of the wound characteristics, donor and recipient vessels, and design for insetting should precede the surgery. Lastly, the skin graft over the muscle flap is less durable than the fasciocutaneous flap and tends to form a callus. To prevent this complication, a p...
Accurate and early prediction of tissue viability is the most significant determinant of tissue flap survival in reconstructive surgery. Perturbation in tissue water content (TWC) is a generic component of the tissue response to such surgeries, and, therefore, may be an important diagnostic target for assessing the extent of flap viability in vivo. We have previously shown that reflective terah...
Background Venous congestion in skin flaps is difficult to detect. This study evaluated the ability of tissue viability imaging (TiVi) to measure changes in the concentration of red blood cells (CRBC), oxygenation, and heterogeneity during vascular provocations in a porcine fasciocutaneous flap model. Methods In 5 pigs, cranial gluteal artery perforator flaps were raised (8 flaps in 5 pigs). ...
INTRODUCTION Flap necrosis and epidermolysis occurs in 18-30% of all mastectomies. Complications may be prevented by intra-operative detection of ischemia. Currently, no technique enables quantitative valuation of mastectomy skin perfusion. Optical Diffusion Imaging Spectroscopy (ViOptix T.Ox Tissue Oximeter) measures the ratio of oxyhemoglobin to deoxyhemoglobin over a 1 x 1 cm area to obtain ...
PRINCIPLES OF FLAP DESIGN The visor flap is a bipedicled flap based on the dorsal branches of the volar digital neurovascular bundles (Figure 1). Transverse amputations of the distal, middle and distal proximal phalanges are most suitable for this technique. Figure 2 illustrates the design of the dorsal flap. The volar/dorsal diameter of the amputation site is measured (A–B). To achieve adequat...
OBJECTIVE To identify post-operative computed tomography (CT) findings associated with delayed flap failures following head and neck cancer surgery. MATERIALS AND METHODS We retrospectively reviewed 60 patients who underwent flap reconstruction after head and neck cancer surgery and post-operative (3-14 days) contrast-enhanced CT scans for suspected complications. Patients were divided into t...
BACKGROUND A surgical technique for closing skin defects following skin cancer (particularly melanoma) removal is described in the present paper. Its use is illustrated in five patients. The technique has been used in 300 cases over the past 7 years and is suitable for all areas of the body from scalp to foot. We have coined the term Keystone Design Perforator Island Flap (KDPIF) because of its...
