RESUMO

Com a finalidade de avaliar a eficácia de um procedimento terapêutico, os autores realizaram uma análise crítica dos vários métodos para produção experimental de aneurismas e elaboraram um método próprio, baseado em uma técnica pré-existente, no qual aneurismas saculares foram produzidos na bifurcação da artéria carótida comum de cães, com enxertos de fragmentos de veias. Os aneurismas assim produzidos apresentaram uma baixa incidência de trombose e uma tendência em aumentar de tamanho e em tornarem-se esféricos.
As características desses aneurismas em muito se assemelham àquelas dos aneurismas de ocorrência natural nas artérias cerebrais do homem, o que os tornam modelos úteis para fins experimentais.


SUMMARY

The authors present a critical analysis of the various methods of experimental production of aneurysms and report their own method in which saccular aneurysms were produced at the bifurcation of the common carotid artery in dogs with vein patch grafts. The objective point of this study was the creation of an experimental model to evaluate the efficacy of a therapeutic procedure. These aneurysms have a low incidence of thrombosis and a tendency to enlarge and to become spherical. They closely simulate the saccular aneurysms developing spontaneously in the cerebral arteries of man, and as such are useful models for experimental purposes.
