Effect of bone marrow mesenchymal stem cells on perforator skin flap survival area in rats.

Br J Oral Maxillofac Surg 2020 May 20. Epub 2020 May 20.

Department of Plastic Surgery, Beijing Hospital, National Center of Gerontology, No. 1 Da-Hua Road, Beijing 100730, China. Electronic address:

Trans-territory perforator flaps are commonly used to reconstruct large defects of the soft tissues. The distal portion of the flap often becomes necrotic, however, as a result of the jeopardised vasculature of choke zone II. The trophic and vascular regenerative properties of bone marrow mesenchymal stem cells (BMSC) seemed to be a promising approach to prevent flaps becoming ischaemic. Read More

Shanghai Key Laboratory for Prevention and Treatment of Bone and Joint Diseases Shanghai Institute of Traumatology and Orthopaedics Ruijin Hospital Shanghai Jiao Tong University School of Medicine 197 Ruijin 2nd Road Shanghai 200025 P. R. China.

The development of science and technology often drew lessons from natural phenomena. Herein, inspired by drying-driven curling of apple peels, hydrogel-based micro-scaled hollow tubules (MHTs) are proposed for biomimicking microvessels, which promote microcirculation and improve the survival of random skin flaps. MHTs with various pipeline structures are fabricated using hydrogel in corresponding shapes, such as Y-branches, anastomosis rings, and triangle loops. Read More

FGF21 augments autophagy in random-pattern skin flaps via AMPK signaling pathways and improves tissue survival.

Cell Death Dis 2019 11 18;10(12):872. Epub 2019 Nov 18.

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

Random-pattern skin flap is commonly used for surgical tissue reconstruction due to its ease and lack of axial vascular limitation. However, ischemic necrosis is a common complication, especially in distal parts of skin flaps. Previous studies have shown that FGF21 can promote angiogenesis and protect against ischemic cardiovascular disease, but little is known about the effect of FGF21 on flap survival. Read More

In 600 BC, the first pedicled direct cutaneous artery perforator flap-the supravicular artery perforator flap was harvested by Sushruta. In 1973, the first free perforator flap-the superficial circumflex iliac artery flap in the groin was reported by Daniel and Taylor. In 1982, the septocutaneous perforator flap was reported by academician Zhong Shizhen. Read More

The "Standing Cone" Flap for Thumb: A Spinoff the Hypogastric Flap in Combined Defects of Dorsum of Hand and Thumb.

Hand (N Y) 2019 Jun 3:1558944719851166. Epub 2019 Jun 3.

1 Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Background: The management of combined defects of the dorsum of the hand and the thumb can be quite challenging. The conventional teaching has been to use more than 1 flap for such discontinuous defects of the hand.

Methods: We present a novel technique to provide a reliable skin cover to a concomitant second defect over thumb, which otherwise would require an additional flap, by recruiting the excess skin available after closure of the primary flap donor site of the hypogastric flap being used for the defect on the dorsum of hand.

Mesenchymal stem cells improve survival in ischemic diabetic random skin flap via increased angiogenesis and VEGF expression.

J Cell Biochem 2019 10 24;120(10):17491-17499. Epub 2019 May 24.

Price Institute of Surgical Research, University of Louisville, Louisville, Kentucky.

Random skin flaps (RSFs) are cutaneous flaps. Despite the negative impact of diabetes mellitus (DM) on RSF viability, they are commonly used in diabetic patients. In this study, we have assessed bone marrow mesenchymal stem cell (BMMSC) treatment on RSF survival, tensiometrical parameters, angiogenesis, and mast cells (MCs) count in an ischemic RSF model in rats with type 1 DM (T1DM).

Therapeutic potential of pravastatin for random skin flaps necrosis: involvement of promoting angiogenesis and inhibiting apoptosis and oxidative stress.

Drug Des Devel Ther 2019 1;13:1461-1472. Epub 2019 May 1.

The Second Clinical Medical College of Wenzhou Medical University, Wenzhou 325027, People's Republic of China.

Random skin flap is frequently used in plastic and reconstructive surgery, but its distal part often occurs ischemia and necrosis. Pravastatin (Prava) with bioactivities of pro-angiogenesis, anti-apoptosis and anti-oxidative stress, may be beneficial for flap survival. A modified McFarlane flap model was performed in Sprague-Dawley rats. Read More

Antithrombotic effect of epigallocatechin gallate on the patency of arterial microvascular anastomoses.

Arch Plast Surg 2019 May 15;46(3):214-220. Epub 2019 May 15.

Department of Plastic, Aesthetic, and Reconstructive Surgery, Ankara Numune Training and Research Hospital, Ankara, Turkey.

Background: Microvascular anastomosis patency is adversely affected by local and systemic factors. Impaired intimal recovery and endothelial mechanisms promoting thrombus formation at the anastomotic site are common etiological factors of reduced anastomosis patency. Epigallocatechin gallate (EGCG) is a catechin derivative belonging to the flavonoid subgroup and is present in green tea (Camellia sinensis). Read More

Department of Burns and Plastic Surgery, Beijing Fengtai You'anmen Hospital, Beijing 100069, China.

Ten patients with perianal necrotizing fasciitis were admitted to our department from June to December 2016. There were 8 men and 2 women among the patients, aged 42 to 69 years. Early and complete debridement surgery and comprehensive supportive treatment during perioperative period were carried out to quickly stabilize the patient's overall condition, and wounds were sutured directly or repaired with autologous scalps and or adjacent local random flaps.

Fat Extract Improves Random Pattern Skin Flap Survival in a Rat Model.

Aesthet Surg J 2019 11;39(12):NP504-NP514

Department of Plastic and Reconstructive Surgery, Shanghai 9th People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai Key Laboratory of Tissue Engineering, Shanghai, China.

Background: Adipose tissue and its derivatives, including adipose-derived stem cells, stromal vascular fraction (SVF), and SVF-gel, have been utilized in the treatment of many ischemic disorders. However, the utilization of these products is limited in clinical applications by concerns related to the presence of cells in these derivatives.

Objectives: This study aimed to isolate a cell-free fat extract (FE) from fat tissue and to evaluate its proangiogenic ability in vitro as well as its protective effects on skin flap survival in vivo. Read More

J Plast Surg Hand Surg 2019 Aug 19;53(4):198-203. 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
