Method for resection and prosthetic replacement of aneurysm of aortic arch.

We shall describe a case of aneurysm of the transverse aortic arch. The patient was operated upon successuflly. Severe respiratory distress owing to tracheal compression was the indication for emergency surgical therapy. A method is described comprising total cardiopulmonary bypass, hypothermia (28 C.) and local deep myocardial hypothermia. Catheters to cerebral vessels are brought off the main arterial line beyond the pump. Cerebral vascular resistance regulates local blood flow. Coronary perfusion is omitted.
