Abstract
A method for selective perfusion of fluids through blood vessels is controlled by the pressure in the blood vessels. A tubing line open at the proximal end for the perfusion of fluids through a tissue region is introduced into a patient's blood vessel in which perfusion is to be performed. The vessel is sealed off from the line in the area of its proximal end, and fluid is pumped into the vessel. The method is characterized in that a specific set value for the internal pressure of the vessel is measured, and the perfused flow of fluid is regulated during pumping in such a way that the set value for the internal pressure of the vessel is kept as closely as possible.
