Carotid artery inflow and anterograde cerebral perfusion in operations to correct aortic disease

OBJECTIVE: To evaluate the use of the right common carotid artery to establish cardiopulmonary bypass (CPB) and the use of anterograde cerebral perfusion as cerebral protection in patients scheduled for ascending aortic repair surgery. METHOD: Twenty-three patients were submitted to aortic repair because of different aortic diseases. In all of them a Gore-tex tube was anastomosed to the right common carotid artery to establish CPB and anterograde cerebral perfusion during distal anastomosis. Average CPB time was 195 minutes; average temperature was 24 degrees Celsius; average anterograde cerebral hypoperfusion time was 29 minutes; average hospital stay was 18 days. RESULTS: None of the 23 patients had any neurological dysfunction within the first 48 postoperative hours. Prior to discharge, all of them were submitted to the "Mini Mental State Examination (MMSE)" which did not identify any cognitive dysfunction or neurological injury. Two patients developed pulmonary infection, two patients needed dialysis and two patients died due to the high complexity of the cases. There were no perioperative deaths. CONCLUSION: This is a practical, fast, efficient and reproducible way to establish CPB and anterograde cerebral protection, reducing the risk of cerebral ischemia and improving the natural postoperative outcome of these procedures.
