Summary: A two-staged technique for construction of experimental aneurysms in swine is described. The jugular vein is initially anastomosed to the carotid artery. Spontaneous hypertrophy of the vein is modeled by placing restraining sutures to create a fusiform aneurysm. Subsequent endovascular closure of this aneurysm leaves a sidewall aneurysm pouch. Staging allows maturation of the anastomosis, and the technique provides additional targets for endovascular training. Trial has been successful in three animals.
