Transferring the protective effect of remote ischemic preconditioning on skin flap among rats by blood serum.

J Plast Surg Hand Surg 2019 Mar 19:1-6. Epub 2019 Mar 19.

e Department of Nuclear Medicine , School of Medicine, Gaziantep University , Gaziantep , Turkey.

The aim of this study was to show whether the protective effect of remote ischemic preconditioning (RIPC) on flaps can be transferred among different individuals with the transfusion of blood serum. Blood serum was taken from rats without any procedure (Group x), rats 1 hour (Group y) and 24 hours (Group z) after performing RIPC and the remaining rats were divided into six groups. While the random pattern skin flap was performed only in the back region in Group 1, and it was performed 1 hour (Group 2) and 24 hours (Group 3) after induction RIPC. Read More

Metformin Promotes the Survival of Random-Pattern Skin Flaps by Inducing Autophagy via the AMPK-mTOR-TFEB signaling pathway.

Int J Biol Sci 2019 1;15(2):325-340. Epub 2019 Jan 1.

Department of Orthopaedics, The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, Wenzhou 325027, China.

Random-pattern skin flaps are widely used to close defects in reconstructive and plastic surgeries; however, they are vulnerable to necrosis, particularly in the distal portion of the flap. Here, we examined the effects of metformin on flap survival and the mechanisms underlying these effects. Following metformin treatment, the survival area, blood flow, and number of microvessels present in skin flaps were increased on postoperative day 7, whereas tissue edema was reduced. Read More

Background: Since the start of the conflict in the Middle East in 2001, military orthopedic surgeons have faced complex orthopedic injuries including high-energy soft tissue wounds, traumatic amputations, and open fractures. Although orthopedic surgeons are well trained in the management of osseous injuries, the treatment of soft tissue injuries can be technically challenging and unfamiliar. Early washout, debridement of devitalized tissue, external fixation of bony injuries, and antibiotic therapy remain the foundation of early wound management. Read More

In utero Plastic Surgery in Zurich: Successful Use of Distally Pedicled Random Pattern Transposition Flaps for Definitive Skin Closure during Open Fetal Spina Bifida Repair.

Fetal Diagn Ther 2018 20;44(3):173-178. Epub 2017 Dec 20.

Zurich Center for Fetal Diagnosis and Therapy, University Children's Hospital Zurich, Zurich, Switzerland.

Background: One of the intraoperative challenges of fetal spina bifida repair is skin closure when there is an extended skin defect. Thus, we examined whether distally pedicled random pattern transposition flaps (TFs) are a valid option to overcome this problem.

Subjects And Methods: All patients undergoing in utero repair of spina bifida with application of a TF for back skin closure were analyzed focusing on intraoperative flap characteristics and postoperative flap performance. Read More

The Keystone Flap-A Case Series Demonstrating Practical Design, Use, and Applications.

Plast Surg (Oakv) 2017 Aug 25;25(3):184-187. Epub 2017 Jul 25.

Division of Plastic Surgery, Department of Surgery, University of British Columbia, Vancouver, British Columbia, Canada.

Introduction: The keystone design perforator island flap is a trapezoidal-shaped random perforator island flap with many advantages over primary closure, skin grafting, and other local flaps for soft tissue reconstruction commonly encountered with cancer excisions.

Methods: This case series of 39 keystone flaps in 37 patients reviews the practical design, use, and applications of the flap while highlighting certain important considerations. Keystone flaps were designed as in the original description, with a minor modification in the lower extremity where a higher flap to defect width ratio was used. Read More

Multifaceted effects of astragaloside IV on promotion of random pattern skin flap survival in rats.

Am J Transl Res 2017 15;9(9):4161-4172. Epub 2017 Sep 15.

Department of Orthopaedics, The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical UniversityWenzhou 325027, China.

Random pattern skin flap transplantation is frequently applied in plastic and reconstructive surgery, but the distal part of skin flaps often suffers necrosis due to ischemia. Astragaloside IV (AS-IV), a natural saponin purified from Astragalus membranaceus, may have beneficial functions for flap survival. In this study, rats were divided into a control group and an AS-IV treatment group, and underwent surgery using a modified "McFarlane flap" model. Read More

Effects of Human Adipose-Derived Stem Cells on the Survival of Rabbit Ear Composite Grafts.

Arch Plast Surg 2017 Sep 15;44(5):370-377. Epub 2017 Sep 15.

Institute for Human Tissue Restoration, Department of Plastic and Reconstructive Surgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Korea.

Background: Composite grafts are frequently used for facial reconstruction. However, the unpredictability of the results and difficulties with large defects are disadvantages. Adipose-derived stem cells (ADSCs) express several cytokines, and increase the survival of random flaps and fat grafts owing to their angiogenic potential. Read More

Efficacy of In Vivo Electroporation-Mediated IL-10 Gene Delivery on Survival of Skin Flaps.

J Membr Biol 2018 Apr 3;251(2):211-219. Epub 2017 Aug 3.

Department of Dermatology, Inselspital, Bern University Hospital, Bern, Switzerland.

Despite advances in understanding the underlying mechanisms of flap necrosis and improvement in surgical techniques, skin flap necrosis after reconstructive surgery remains a crucial issue. We investigated the efficacy of electroporation-mediated IL-10 gene transfer to random skin flap with an aim to accelerate wound healing and improve skin flap survival. Nine male Wistar rats (300-330 g) were divided in two groups (a) control group (n = 5), only surgery no gene transfer, and (b) experimental group, received electroporation-mediated IL-10 gene transfer 24 h before the surgery as prophylaxis (n = 4).

Effects of gamma-low dose irradiation on skin flap survival in rats.

Phys Med 2017 Aug 29;40:104-109. Epub 2017 Jul 29.

Department of Anatomy and Histology, Urmia University of Medical Sciences, Urmia, Iran.

Purpose: Skin flap necrosis due to inadequate blood supply has remained a common postoperative problem in constructive surgery. As low-dose irradiation (LDI) has been shown to promote the wound-healing process, this study aims to investigate whether LDI could increase neovascularization and skin flap survival in rats.

Methods: McFarlane flaps were created in 21 male rats, which were divided into one control and two treatment groups (Ta and Tb). Read More
