Overview
This article describes an optimized microsurgical technique for creating arterial bifurcation aneurysms in rabbits, mimicking human cerebral aneurysms. The method involves suturing a venous pouch into an artificially created bifurcation of the common carotid arteries, resulting in low morbidity and high aneurysm patency rates.
