Endovascular treatment of berry aneurysms by endosaccular occlusion.

In 90 cases with 93 berry aneurysms endovascular occlusion of the aneurysms was attempted, in 73 of them successfully. There has been a 12% complication rate, including 4% mortality and 8% of cases with neurological deficit, and 9 recurrences. The indications for endovascular treatment of berry aneurysms are discussed. This method seems to be an alternative especially for carotiophthalmic and basilar artery aneurysms.
