Scintiphotographic studies for long-term results in carotid cavernous sinus fistulae.

Scintiphotographic studies as a method for analyzing the brain perfusion in carotid cavernous sinus fistulae before and after surgical treatment with different techniques are presented. Twelve patients have been reexamined long after their operation to prove the sufficient crossover circulation through the circle of Willis while the homolateral carotid artery is impatent. Sufficient perfusion of both hemispheres could be well-documented by this radionuclide method. No neurological deficit was found in clinical examination either.
