Balloon migration into a giant carotid aneurysm after parent artery occlusion using detachable balloons.
We treated a 70-year-old man with a giant paraophthalmic region aneurysm of the right internal carotid artery using the parent artery occlusion technique with three detachable balloons. Initially, the patient did well, but migration of the distal balloon into the aneurysm was detected seven months later. This report suggests that initial parent artery occlusion using balloons will not always induce permanent thrombosis of a large aneurysm, because the occlusion and thrombosis is strictly dependant on the position of the balloons that are used, and adjunct use of coils may be indicated.
