Intracranial aneurysm is major vascular disease which is life-threatening and challenging treatment. Detachable
coil is one of the standard treatments. Because of little knowledge about it, the detachable coils were evaluated by various methods. Animal aneurysm models were also used to test this equipment. In the present study, sidewall aneurysms were created on common carotid arteries of Landrace-Yorkshire-Durocswine. External jugular vein grafts were used as aneurysm sac. End-to-side anastomosis was done. Ten aneurysms were created successfully in 5 swine. There is no perioperative death. This animal aneurysm model is appropriated for coil testing especially in the histopathology aspect.
