Objective: We previously reported that near-infrared irradiation nonthermally induces long-lasting vasodilation of the subdermal plexus by causing apoptosis of vascular smooth muscle cells. To clarify the possible application of near-infrared irradiation to prevent skin flap necrosis, we evaluated the length of axial pattern flap survival in rats by near-infrared irradiation. Methods: A bilaterally symmetric island skin flap was elevated under the panniculus carnosus on the rat dorsum. Half of the flap was subjected to near-infrared irradiation just before flap elevation with a device that simulates solar radiation, which has a specialized contact cooling apparatus to avoid thermal effects...

Introduction: Previously, external hemipelvectomy was the mainstay of treatment for pelvic tumors. However, with technological advancements, limb salvage procedures such as internal hemipelvectomy have emerged as a viable alternative. However, there is limited literature available on long-term outcomes and complications of internal hemipelvectomy, especially from developing countries. Therefore, the objective of this study was to share our experience of internal hemipelvectomy at a tertiary care center in a developing country...

We herein present the unique case of a 68-year-old male diabetic patient who developed sterile necrosis of the sternum 1 month after myocardial revascularization with the use of bilateral internal thoracic artery grafts. The sternum had been closed by the bilateral Robicsek wiring technique. The sternum was removed, and bilateral pectoralis major flaps were used to cover the defect. The patient had an uneventful recovery.

OBJECTIVES: The transverse rectus abdominis musculocutaneous (TRAM) flap is an important option for breast reconstruction. Several studies have recently evaluated whether a greater number of complications result from the use of pedicled TRAM (pTRAM) flaps versus either free TRAM (fTRAM) flaps or deep inferior epigastric artery perforator (DIEP) flaps. To clarify the evidence regarding this issue, we performed an objective meta-analysis of published studies. MATERIALS AND METHODS: A literature search of articles published between January 1, 1990, to January 1, 2017 was performed using the PubMed, EMBASE, Scopus, and Cochrane databases...

Background: Random-pattern flap transfer is commonly used to treat soft-tissue defects. However, flap necrosis remains a serious problem. Naringin accelerates angiogenesis by activating the expression of vascular endothelial growth factor (VEGF). In the present study, we investigated whether naringin improves the survival of random skin flaps. Results: Compared with controls, the naringin-treated groups exhibited significantly larger mean areas of flap survival, significantly increased SOD activity and VEGF expression, and significantly reduced MDA level...

Background: Compromised perfusion as a result of surgical intervention causes a reduction of oxygen and nutrients in tissue and therefore decreased tissue vitality. Quantitative imaging of tissue perfusion during reconstructive surgery, therefore, may reduce the incidence of complications. Non-invasive optical techniques allow real-time tissue imaging, with high resolution and high contrast. The objectives of this study are, first, to assess the feasibility and accuracy of optical coherence tomography (OCT), sidestream darkfield microscopy (SDF), laser speckle contrast imaging (LSCI), and fluorescence imaging (FI) for quantitative perfusion imaging and, second, to identify/search for criteria that enable risk prediction of necrosis during gastric tube and free flap reconstruction...

Abstarct Background: Due to the high rate of donor site complications the Radial Forearm Flap (RFF) has lost ground in favor of the Antero-lateral tight flap (ALT) and other flaps. We have designed a reconstruction algorithm for reconstruction of its donor site. The goal of this study was to retrospectively evaluate the impact of this algorithm on RFF donor site complication rates. METHODS: The authors analyzed retrospectively 31 patients who underwent free radial forearm flap reconstruction between November 2009 and May 2013...

Diclofenac sodium is a widely used nonsteroidal anti-inflammatory drug (NSAID) for relief of inflammatory pain. A recent formulation combines this drug with hydroxypropyl-β-cyclodextrin (HPβCD) to improve its solubility and to enable subcutaneous administration. Previous studies confirmed the efficacy of this combination. This study's aim was to evaluate the efficacy, safety, and local tolerability of diclofenac HPβCD administered as a local submucosal injection prior to lower third molar surgery. We conducted a prospective, randomized, double-blind, placebo-controlled, parallel-group phase II single-center study...

Ischaemic insult in the skin flaps is a major problem in reconstructive surgery particularly in patients with diabetes mellitus. Here, we sought to investigate the effectiveness of ischaemic preconditioning (IP) on diabetic skin flaps in rat animal model. Hundred Wistar rats (90 streptozotocin treated animals and 10 nondiabetic controls) were used. Diabetes mellitus was confirmed by measuring glucose level in blood, HbA1c, and ketonuria. We used blood vessel clamping, hind limb tourniquet, and NO donors (Spermine/NO complex) to induce short-term ischaemia of tissues that will be excised for skin flaps...

Background: Management of nail injuries can often be a challenging experience, especially in presence of complex fingertips' injuries that include soft tissue loss and distal phalanx injury. Most studies found in the literature focus on individual injuries and describe methods to tackle those injuries, notwithstanding the fact that the nail, nailbed, distal phalanx, soft tissue and skin of the finger tip form a complex and often more than one element of this complex is injured. This retrospective study therefore focuses on the management of nail bed injuries as a part of the complex finger tip injury and outlines the surgical principles and techniques that were used in their management...

BACKGROUND: Flap necrosis due to insufficient blood supply is a common postoperative complication in random pattern flaps. Stem cell therapies have emerged as promising biologics for tissue ischemia. A novel fat derived product, stromal vascular fraction gel (SVF-gel), can be prepared with lipoaspirate through simple mechanical processing, removing only the lipid content. SVF-gel enriches adipose-derived stem cells and potentially beneficial for flap necrosis. METHODS: Nude mice ischemic flaps were treated with human SVF-gel, stromal vascular fraction (SVF) cell suspension or saline (n = 10)...

BACKGROUND: Given the critical position of central glabella among the frontal, nasal, and supraorbital aesthetic subunits of the face, the reconstruction of large defects in this area represents a surgical challenge. METHODS: We describe a surgical technique based on a modified, curved, A-T flap to repair a large glabellar defect. RESULTS: Our modification is useful for large glabellar defects because it enables the distribution of the tension all over the reconstruction sides, avoiding a stressed central area and the subsequent risk of necrosis; functionally, it respects the eyebrows position and since the advancement is parallel to their major axes, it avoids the reduction of the distance between them...

Maxillary defects with buconasal/businusal communications are situations difficult to manage and solve. Several treatment options are available on the literature, each one with its indication. Temporal muscle flap is one of these options, being a technique that requires more experience of the surgeon to be properly performed and that is mainly indicated for difficult cases, large defects and those nonresponsive to simpler techniques. The main purpose of this paper is to report 3 clinical patients of the application of the temporal muscle flap for the closure of extensive oral defects...

INTRODUCTION: Successful breast reconstruction using deep inferior epigastric perforator (DIEP) flaps depends on optimal perforator choice. Circummuscular wraparound medial perforators allow for no rectus dissection and minimal fascial incisions, often presenting as an ideal option. The aim of our study is to evaluate outcomes of the single medial wraparound perforator flap in comparison to more traditional transmuscular single-perforator DIEP flaps. PATIENTS AND METHODS: A retrospective chart review was conducted of all DIEP flaps performed by the senior author from 2011 to 2016, yielding 269 flaps on 157 patients...

Reconstruction of thigh defects is usually straightforward, but in cases of poor soft tissue quality, free flap reconstruction is not possible due to the absence of recipient vessels. The turbocharge technique may increase the viable, vascularized area of a flap. In this report we present a case of the use of a turbocharged bilateral pedicled DIEP flap for reconstruction of thigh defect without recipient vessels. A 29-year-old woman who underwent neoadjuvant chemotherapy plus radiation therapy for a leiomyosarcoma on the left thigh...

BACKGROUND: The conventional procedure of the sural neuro-fasciocutaneous flap enables the supply of blood and venous drainage by increasing the width of the adipofascial tissue and preserving tiny venous return routes. Moreover, skin graft is a common method for donor site closure, which may lead to some complications and influence the aesthetic appearance. We report modifications for a distally based sural neuro-fasciocutaneous perforator flap and a relaying flap for donor site closure without skin graft...
