A simple technique for retrograde cerebral perfusion during circulatory arrest

We describe a simple and safe technique for achieving retrograde cerebral perfusion via a small coronary sinus type catheter placed in the superior vena cava. This method is especially useful when the need for circulatory arrest is first recognized intraoperatively and a single two-stage venous cannula has already been placed for cardiopulmonary bypass. The advantages of this technique over other currently employed methods for retrograde cerebral perfusion are discussed.
