Simple Method to Stabilize the Blood Pressure in the Aortic Arch During Distal Crossclamping. An Experimental Study

Abstract

A method is presented to stabilize the blood pressure on the aortic arch during crossclamping. The procedure consists of inserting a cannula into the proximal aorta and connecting it to a plastic buffer-bag suspended above the operating table at a level corresponding to the desired blood pressure in the aortic arch. Experimentally the method proved to be highly effective to protect the heart from acute hypertension and from overdistention injury regardless of the level of aortic crossclamping.
