A SIMPLE TECHNIQUE FOR RETROGRADE CEREBRAL PERFUSION DURING CIRCULATORY ARREST

We describe a simple and safe technique for achieving retrograde cereb ral perfusion via a small coronary sinus type catheter placed in the s uperior vena cava. This method is especially useful when the need for circulatory arrest is first recognized intraoperatively and a single t wo-stage venous cannula has already been placed for cardiopulmonary by pass. The advantages of this technique over other currently employed m ethods for retrograde cerebral perfusion are discussed.
