Resumo

CONTEXTO: O desenvolvimento de terapia alternativa à convencional para a destruição de microvarizes e telangiectasias sem o uso de produtos químicos tem como objetivo reduzir os efeitos colaterais, faz uso de agulha para lise mecânica dos vasos e tem como modelo experimental galinhas da linhagem Lohmann Brown. OBJETIVO: Elaborar uma nova técnica, desenvolvendo um tratamento alternativo, sem uso de produtos químicos, objetivando a redução dos efeitos colaterais. MÉTODOS: Foram utilizadas 30 galinhas da linhagem Lohmann Brown, sendo que 15 foram submetidas ao método convencional de tratamento de microvarizes e telangiectasias (grupo-controle) e as outras 15 receberam o tratamento experimental proposto (grupo experimental). O grupo experimental foi tratado com agulha de lise vascular, percorrendo todo o trajeto dos vasos escolhidos em punções escalonadas até que todo o vaso ser atingido. O grupo-controle foi tratado com oleato de monoetanolamina e glicose a 50%, puncionando-se o vaso com agulha 13 x 3 mm e injetando-se, em média, 0,3 mL da solução em cada vaso. RESULTADOS: Dos 50 vasos tratados no grupo experimental, dois apresentaram recidiva total, cinco apresentaram recidiva parcial, e 43 apresentaram destruição (lise) satisfatória; enquanto que, no grupo-controle, dos 51 vasos tratados, quatro apresentaram recidiva total, 12, recidiva parcial, 22, destruição satisfatória, e em 13 ocorreu endurecimento de trajeto. CONCLUSÃO: O presente estudo demonstrou que o método experimental proposto, com uso de agulha de lise vascular, possui mais eficiência no tratamento de microvarizes se comparado com o método convencional, devido à redução das recidivas e à ausência de hipercromia de trajeto endurecido.

Abstract

BACKGROUND: The development of an alternative to the conventional therapy for microvarices and telangiectasias without using chemical products aims at reducing side effects, using a needle for mechanical lysis of vessels. It uses Lohmann Brown hens as the experimental model. OBJECTIVE: To develop a new technique, creating an alternative treatment without using chemical products, aiming at the reduction of side effects. METHODS: Thirty Lohmann Brown hens were used, 15 submitted to the conventional method of treating microvarices and telangiectasias (control group) and 15 receiving the proposed experimental treatment (experimental group). The experimental group was treated using a needle for vascular lysis, passing through the whole extension of chosen vessels in staggered punctures until the whole vessel was reached. The control group was treated with ethanolamine oleate and 50% glucose, puncturing the vessel with a 13 x 3 mm needle and injecting on average 0.3 mL of the solution in each vessel. RESULTS: Of the 50 vessels treated in the experimental group, two presented total recurrence, five partial recurrence and 43 satisfactory destruction (lysis), whereas of the 51 vessels treated in the control group, four presented total recurrence, 12 partial recurrence, 22 satisfactory destruction and 13 presented conduit vessel stiffness. CONCLUSION: The present study demonstrated that the experimental method using a needle for vascular lysis is more efficient for the treatment of microvarices when compared with the conventional method, due to reduction in recurrence rates and absence of hyperchromatism of conduit vessel stiffness.
