In 16 acute stroke patients with focal cerebral hyperemia angiography and regional cerebral blood flow (rCBF) were studied 1 to 4 days post stroke. CT was performed twice with and without contrast enhancement 3 +/- 1 days and 16 +/- 4 days post stroke. Angiographic evidence of focal cerebral hyperemia was seen in 8 patients in the form of early filling veins. In 5 of these the hyperemic areas were located within infarcted areas and in 3 patients in areas which appeared normal on CT. In the remaining 8 patients the hyperemias were located perifocally around ischemic infarcts. Early filling veins were not seen in this type of hyperemia. The blood flow was higher and the transit time of the contrast medium was faster in the former type of hyperemia probably because of arteriovenous shunting. Contrast enhancement was not observed on the early CT but was typically seen in the infarcts on the late CT at a time when the hyperemic state is known to have vanished. It is concluded that focal cerebral hyperemia is not responsible for contrast enhancement on CT.
