Models of experimental saccular aneurysms of carotid arteries in canine

Objective To study the availability by making experimental saccular aneurysm models of carotid arteries in canine similar to human intracranial aneurysms.Methods Twenty healthy canines with experimental saccular side-wall aneurysms of carotid arteries were created successfully by surgery. Results Forty experimental saccular side-wall aneurysms of carotid arteries were created successfully with 36 aneurysms and parent arteries maintaining patency with each other and four spontaneously occluded confirmed by angiography.Model successfurll rate reached 90%.Conclusions Experimental saccular side-wall aneurysms of carotid arteries in canines were one of best models created for simulating human intracranial aneurysms.
