Objective To summarize the methods and experiences of surgical treatment of aortic arch diseases with four branches aortic graft under deep hypothermia circulatory arrest （DHCA） and antegrade selective cerebral perfusion （ASCP）. Methods In 2004 from September to December, surgical treatment of 12 patients with 7 aortic aneurysm（4 cases with ascending aorta and aortic arch aneurysm, 3 cases with aneurysm of aortic isthmus） and 5 aortic dissection（DeBakey Ⅰ 1 case, DeBakey Ⅱ 3 cases, DeBakey Ⅲ 1 case） were collected in Gunma Prefectural Cardiovascular Center. All operations were carried out under DHCA and ASCP, and four branches aortic graft were used to replace the aortic arch. The Bentall procedure, total and partial arch replacement and elephant trunk technique were undertaken in different patients. Results Total 12 patients recovered from the great vessel diseases smoothly without severe cerebral and other systematic complications, the time of operation was 5.5±1.7 h, the period of DHCA was 42.2±12.9min, 4 cases with no blood transfusion, the time of hospitalization was 22.3±7.2d. Conclusion ASCP is a safe. and effective method of cerebral protection during circulation arrest, and four branches aortic graft may shorten the time of DHCA and simplify the procedure of aortic arch replacement.
