Cerebral Arteriovenous Malformation Feeding Artery Aneurysms: A Theoretical Model of Intravascular Pressure Changes after Treatment

Abstract

In this simulation, shunt obliteration increased pressure in the nidus and feeding arteries with little effect on the proximal circulation. The shunt provided a "buffering" effect, i.e., higher flow fistulas were exposed to smaller variations in intravascular pressure in feeding artery and nidal pressures during manipulation of systemic pressure.
