Aneurismas experimentais: proposição de nova tecnica

Abstract

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.

“…The techniques used to create the experimental aneurysms are varied 27 . Most work with pigs, using anastomosis techniques similar to the one of this study, using the external jugular 13,28,29 . In some, there was spontaneous thrombosis of the aneurysm immediately after its making, which led to immediate change of technique 28 .…”

“…Most work with pigs, using anastomosis techniques similar to the one of this study, using the external jugular 13,28,29 . In some, there was spontaneous thrombosis of the aneurysm immediately after its making, which led to immediate change of technique 28 . In others, there were rates of up to 50% of thrombosis after 14 days of follow-up 13 .…”
