Coil embolization of ruptured middle cerebral artery aneurysms in the first 2 months of life

Intracranial artery aneurysms are very rare in infants. There have been no previous reports of coil embolization to branches of the middle cerebral artery (MCA) in infants. The authors describe successful embolization of ruptured aneurysms of the right frontoopercular MCA branch in a 31-day-old infant, and of the left sylvian MCA branch in a 54-day-old infant. One of the cases involves a dissection flap. The authors also review cases in which coil embolization was used for intracranial aneurysms in the first 2 months of life.
