Cerebral angiogram performed - images not available.
Cerebral Angiography Report
Under local anesthesia through right femoral approach cerebral angiogram was done after selective cannulation of right and left carotid and right and left vertebral arteries. Selective cannulation of internal and external carotid arteries performed.
This study shows type D dural fistula in the superior sagittal sinus at the vertex being supplied by meningeal and superficial arteries on both sides, parietal branches of the ACA and ophthalmic via the palpebral branches of upper eye lid.
There is another fistula at the torcula with main feeders from the right occipital artery. There are multiple dilated cortical venous radicals with venous ectasia in the brain draining via cavernous sinuses. The circulation time is prolonged to 14.0 seconds with early filling of the sagittal sinus via fistula.
Conclusion: dural arteriovenous fistulas (dAVF)
