PURPOSE To develop an experimental model to be used in the study of low level Laser therapy on viability of random skin flap in rats. METHODS The sample was 24 Wistar-EPM rats. The random skin flap measured 10 x 4 cm and a plastic sheet was interposed between the flap and donor site. Group 1 (control) underwent sham irradiation with diode laser (830 nm). Group 2 was submitted to laser irradia...

OBJECTIVES Covering tissue defects using skin flaps is a basic surgical strategy for plastic and reconstructive surgery. The aim of this study was to evaluate the effects of chicken embryo extract (CEE) and bone marrow derived mesenchymal stem cells (BM-MSCs) on random skin flap survival (RSF) in rats. Using chicken embryo extract can be an ideal environment for the growth and proliferation of ...

OBJECTIVE To evaluate the effect of hemodynamic remodeling on the survival status of the arterialized venous flaps (AVFs) and investigate the mechanism of this procedure. MATERIALS AND METHODS Two 7 x 9 cm skin flaps in each rabbit (n=36) were designed symmetrically in the abdomen. The thoracoepigastric pedicle and one femoral artery were used as vascular sources. Four groups were included: C...

BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal random-pattern ski...

BACKGROUND Partial or complete necrosis of a skin flap is a common problem. Polydeoxyribonucleotide (PDRN) can be extracted from trout sperm and used as a tissue repair agent. The aim of this study was to investigate whether PDRN could improve the survival of random pattern skin flaps in rats. METHODS Twenty-two male Sprague-Dawley rats were randomly divided into two groups: the PDRN treatmen...

This study evaluated the reverse flap technique on Saphen artery (Reverse saphenous conduit flap), used in veterinary plastic surgery to close wounds of tarsus and metatarsus. Due small volume low elasticity skin these areas, defects can be a very difficult task. To solve this problem, uses artery. method was effectively 13 cases dogs with wound distal part pelvic limb. We degree survival, comp...

PURPOSE To investigate the effects of different low-level laser therapy (LLLT) doses on random skin flap rats. METHODS Forty Wistar rats were randomly divided in four groups. The control group (CG) was not irradiated. The experimental groups were irradiated with a diode laser 670 nm with different energies per point: group 2 (G2) with 0.06 J; group 3 (G3) 0.15 J and group 4 (G4) 0.57 J. The t...

introduction: providing the material for penile reconstruction after release of chordee associated with hypospadias is challenging. we have used the preputial vascularized island flap for this purpose. we report the results of this prospective study. materials and methods: one hundred and twelve boys ranging from 13 months to 12 years of age were enrolled in this study. the location of meatus r...

Two patients with penile skin loss who were operated in 1991 are reviewed retrospectively. In both of them skin grafting was mandatory (due to large skin defects on the penile shaft). Causative factors were localized infection in one case and verrucae accuminata in another. In both cases a random flap from the skin of the inner surface of the thigh was applied. The pedicle flap was later t...

the distal third of the tibia, ankle and heel area is difficult to reconstruct. for small to medium size defects, local flaps are often an easier alternative than free flap. in lower limb surgery, the sural flap is based on this principle and this flap is becoming increasingly popular. the distally based superficial sural artery flap, first described as a distally based neuro skin flap by masqu...
