Embolization of arteriovenous malformation using freeze-dried iohexol as contrast material.
We report a case of ruptured callosal arteriovenous malformation embolized preoperatively with freeze-dried iohexol (Omnipaque *) as the contrast medium for an alcohol-soluble liquid embolic material. Iohexol was dissolved in 15% alcohol to produce a 25% solution (100 mg/ml iodine), which proved adequate for monitoring with digital subtraction angiography.
