Fusiform dilatations of the internal carotid artery following surgery for pediatric suprasellar tumors.
Fusiform dilatations of the internal carotid artery (FDCA) represent a vascular complication following surgery for suprasellar tumors in children. In a long-term follow-up of 62 children we identified 7 children (11.3%) with a FDCA. In all children the FDCA was present within 15 months following surgery. It was not related to radiotherapy or a distinct histology. In 3 children the FDCA remained unchanged during the follow-up, in 3 children there was a progression and 1 child revealed a regression within 6 months. Clinically the FDCA was inapparent in all cases and not treated. In a follow-up study of an adult population who underwent surgery for suprasellar tumors no case of FDCA was encountered. Potential pathomechanisms and indications for treatment are discussed.
