Morphologic Changes of Cerebral Veins in Hypertensive Rats: Venous Collagenosis Is Associated with Hypertension

The increased visibility of cerebral veins on SWI as a sign of venous hypertension and the thickened cerebral venous walls (venous collagenosis), which may play a role in cerebral ischemia and/or infarction, are both consequences of long-term hypertension in hypertensive rats.
