Experimental models of bifurcation and terminal aneurysms: construction techniques in swine.

摘要

We report our preliminary experience in the surgical construction of five experimental bifurcation and terminal aneurysm models in swine. We used unilateral neck vessels to construct models in which the relative directions and sizes of the parent and daughter arteries could be varied by surgery, resulting in aneurysms with high morphologic similarity to human intracranial lesions. Steps in the construction of each model are detailed.
