ObjectiveTo summarize clinical experience of total aortic arch reconstruction with triple-branched stent graft placement in elderly patients with Stanford type A aortic dissection (SAAD).
MethodsFrom December 2008 to December 2012, 46 elderly SAAD patients underwent total aortic arch reconstruction with triple-branched stent graft placement under deep hypothermic circulatory arrest and selective cerebral perfusion (SCP)in Department of Cardiova-scular Surgery, Henan Provincial Chest Hospital. There were 37 male and 9 female patients with their age of 65-75 (68.2±5.0)years. There were 6 patients undergoing modified David procedure, 1 patient undergoing Bentall procedure, 2 patients undergoing Wheat procedure, and 37 patients undergoing ascending aortic replacement.
ResultsThere was no in-hos-pital death. Cardiopulmonary bypass time was 135-183 (131.1±10.5)minutes, aortic cross-clamping time was 81-100 (61.5±18.3)minutes, and SCP time was 19-28 (24.4±5.6)minutes. Postoperative complications included low cardiac output syndrome in 3 patients, acute renal failure in 2 patients, pleural effusion in 5 patients, lung infection in 2 patients, and sternal dehiscence in 1 patient, who were all cured after treatment. All the patients were followed up for 3 to 12 months without complication related to the stent graft.
ConclusionTotal aortic arch reconstruction with triple-branched stent graft placement is an easy surgical procedure for SAAD with a high successful rate and low morbidity, and especially suitable for elderly patients who can't bear traditional operation.
