BACKGROUND: Hypothermia has been an essential technique in aortic arch surgery for protecting the brain. To reduce the adverse effect caused by hypothermia, we modified the perfusion technique in aortic arch surgery. Initial results using this modified technique are reviewed.
METHODS: Nineteen patients were operated on for aortic aneurysm involving the aortic arch. Fifteen patients had nondissecting aneurysm and four patients had type A dissecting aneurysm including three with acute dissection. While on the hypothermic (25 degrees C to 28 degrees C of nasopharyngeal temperature) antegrade selective cerebral perfusion (SCP) was performed by direct cannulation to the brachiocephalic and left common carotid arteries, visceral perfusion via the femoral artery or graft was performed with tepid or normothermia (34 degrees C to 36 degrees C).
RESULTS: Hospital mortality rate was 5.3% (1/19 patients). None of the 19 patients suffered from stroke postoperatively. Duration of total cardiopulmonary bypass and SCP was 144 +/- 36 minutes and 90 +/- 34 minutes, respectively. Eighteen surviving patients were extubated at 9.4 +/- 13.2 hours and stayed in the intensive care unit (ICU) for 3.0 +/- 1.8 days after the surgery.
CONCLUSIONS: Our initial experience revealed that the modified technique using simultaneous hypothermic cerebral perfusion and tepid or normothermic visceral perfusion can be a useful adjunct during aortic arch surgery providing quick recovery.
