The cerebral circulation in cases of carotid cavernous fistula. Findings of single photon emission computed tomography.
Ten patients with carotid cavernous fistula (CCF) were reviewed. Single photon emission computed tomography (SPECT) for regional cerebral blood flow (rCBF) study was performed in six patients with fast flow shunt. Five of these six patients with fast flow shunt angiographically demonstrated cortical venous drainage, and two of these patients suffered intracerebral hemorrhage. The rCBF decreased in the region demonstrating the cortical venous drainage in five patients, and in one patient the angiography demonstrated arterial steal and the rCBF decreased in a part of the ipsilateral cerebral hemisphere. SPECT proved to be useful in assessing the cerebral circulation in cases of CCF.
