Use of thermography in skin grafts after the application of therapeutic ultrasound in Wistar rats.

Purpose To analyze changes in the thermal pattern in the skin graft receptor bed, after the use of therapeutic ultrasound through the thermographic images. Methods Eighteen Rattus norvegicus albinus Wistar, separated into two groups: GST groups (without tumor and without treatment with ultrasound) and GT (with tumor and treatment with ultrasound). In the GT group, induction of carcinogenesis was performed by single intradermal application of 0.05 ml DMBA at 0.5%, diluted in acetone. Subsequently, a technique of reconstructive grafting surgery of the mesh type was performed in both groups and treatment with therapeutic ultrasound was performed in the GT group the alternate day protocol at 3, 6, 10 and 15 days after the procedure. The thermographic evaluation occurred on days 3, 6, 10 and 15 after the grafting. Results There was a significant difference between the statistical evaluation of the temperature of the control group when compared to the treated group, on the different evaluation days (p <0.0001). Conclusion The thermographic analysis of the images was effective in evaluating the healing process, being the use of thermography feasible to evaluate changes in the thermal standard in the surgical bed, besides the beneficial effects of the US.

Application of a meshed skin graft in the surgical bed immediately after resection of neurofibrosarcoma in the distal limb region of a dog

Background: Malignant peripheral nerve sheath tumors are neurogenic neoplasms that originate from cells that surroundthe axons of peripheral nerves. Surgery is the treatment of choice for peripheral nerve sheath tumors. They have a betterprognosis when the lesion is in the extremity of a limb and the surgeon leaves wide peripheral margins after resection.However, this procedure makes local treatment a challenge due to difficult wound healing in this region. This report describes a successful case involving the use of a meshed skin graft immediately after resection of a neurofibrosarcoma inthe distal region of the radius bone of a dog.Case: A 6-year-old Boxer bitch weighing 40 kg was admitted with a history of a round, firm, non-ulcerated skin noduleattached to the lateral side of the distal region of the right radius bone, which had been present for about 40 days. Fineneedle aspiration cytology of the lesion showed the presence of mesenchymal cells, suggesting a sarcoma. Thus, the decision was made for an incisional biopsy to confirm the diagnosis and for the preparation of a subdermal pattern tubular flapfor subsequent rotation and transposition to close the wound that would be formed after the complete removal of the lesion.After the 7th postoperative day, the diagnosis of low-grade neurofibrosarcoma was confirmed and due to the presence ofnecrotic onset in the middle portion of the tubular flap, further surgical intervention was scheduled for the resection of thetube flap, en bloc removal of the neoplastic lesion with peripheral margins of 2 cm, and wound closure with a free skingraft. A mesh skin graft was made with a portion of the right flank skin. The mesh graft was carefully implanted on therecipient bed using simple interrupted sutures with a 3-0 non-absorbable monofilament suture material. A dressing madewith water-based sterile lubricating solution and...(AU)

Emprego de plasma rico em plaquetas em retalho de padrão axial da artéria genicular medial em cão: relato de caso / Use of platelet rich plasma in axial pattern flap of medial genicular artery in dog: case report / El uso de plasma rico en plaquetas en la solapa de la arteria geniculado medial en un perro: un informe de caso

As feridas de pele apresentam alta prevalência no atendimento clínico de pequenos animais, incluindo lesões provenientes de traumatismo, além de defeitos extensos decorrentes da ressecção de neoplasias. Porém problemas relacionados com a neovascularização em procedimentos cirúrgicos como presença de necrose podem estar presentes. Deste modo, o emprego do plasma rico em plaquetas em cirurgias reconstrutivas é indicado por favorecer a integração do retalho no leito receptor por meio da estimulação da angiogênese, bem como a reduzir a necrose na extremidade dos retalhos. O presente trabalho tem como objetivo relatar um caso de emprego de plasma rico em plaquetas em retalho de padrão axial da artéria genicular medial na correção de defeitos extenso proveniente da ressecção de neoplasia em cão. Os resultados evidenciam que a utilização do plasma rico em plaquetas autólogo em cirurgia reconstrutiva favoreceu a integração do retalho no leito receptor reduzindo a ocorrência de necrose na extremidade dos retalhos.

Skin wounds present high prevalence in the clinical care of small animals, including injuries from trauma, as well as extensive defects resulting from resection of tumors. However, problems related to neovascularization in surgical procedures such as the presence of necrosis may be present. Thus, the use of platelet rich plasma in reconstructive surgeries is indicated by favoring the integration of the flap in the recipient bed by stimulation of angiogenesis, as well as reducing necrosis at the end of the flaps. This paper aims to report a case of use of platelet rich plasma in the axial pattern of the medial genicular artery in the correction of extensive defects resulting from the resection of neoplasia in dogs. The results evidenced that the use of autologous platelet-rich plasma in reconstructive surgery favored the integration of the flap in the receptor bed reducing the presence of necrosis at the end of the flaps.

Las heridas de piel presentan elevada prevalencia durante la atención clínica de pequeños animales e incluyen lesiones secundarias por trauma y defectos extensos posteriores a escisión de tumores. Por lo tanto, pueden presentarse alteraciones de neovascularización y posterior presencia de necrosis tras la realización de procedimientos quirúrgicos; por esta razón, se indica el uso de plasma rico en plaquetas durante la cirugía reconstructiva para favorecer la integración del colgajo con el lecho receptor estimulando la angiogénesis y reduciendo la presencia de necrosis en el extremo de los colgajos. El presente trabajo tiene por objetivo relatar un caso mediante el uso de patrón axial de la arteria genicular medial asociado al uso de plasma rico en plaquetas para corregir un defecto extenso tras la resección quirúrgica de una neoplasia. Los resultados demostraron que la utilización de plasma rico en plaquetas autólogo favoreció la integración del colgajo sobre el lecho receptor, reduciendo la necrosis en el extremo distal del colgajo.
