title: Migration of detachable mini-balloon from the ICA causing occlusion of the MCA. Case report.
abstract: This patient had an aneurysm on the internal carotid artery that was responsible for episodes of severe hemorrhage through the nose. During occlusion of the aneurysm by a detachable balloon, the balloon became dislodged and migrated, obstructing the middle cerebral artery territory and causing a life-threatening situation. This was treated promptly and successfully by removal of the balloon and repair of the artery. Attention is drawn to the risk of such migration occurring, and the possible causes.
