Anesthetic management for patients undergoing total thoracoabdominal aorta replacement without cardiopulmonary bypass

Abstract

To summarize the experience in anesthetic management for total thoracoabdominal aorta replacement without cardiopulmonary bypass. From October 2009 to September 2010, 10 patients of Fuwai Hospital received off-pump total thoracoabdominal aorta replacement. Of these patients, 5 were subjected to Standford B aortic dissection, 2 were Standford A aortic dissection received total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta.1 were Marfan's syndrome, and 2 were thoracoabdominal aorta. All operations used the technique which preserved blood was transfused back by pump via the femoral artery. The average surgery time was (7.4 ± 1.2) h and extubation time was (14.1 ± 2.5) h, the descending thoracic aorta cross clamp time was (11.5 ± 3.6) min, the intercostal artery reconstruction time was (16.4 ± 5.5) min, the required amount of blood products was fresh frozen plasma (600.5 ± 542.8) ml, platelet(1.7 ± 0.8) U, red blood cell (4.3 ± 2.4) U, auto blood salvage (465.7 ± 242.3) ml. Three patients occurred atelectasis and one patient occurred sero peritoneum postoperation. All of the 10 patients were discharged from hospital without any neurologic complications. The anesthetic management for total thoracoabdominal aorta replacement without cardiopulmonary bypass is feasible. It can reduce the side effects of deep hypothermia circulatory arrest and had a good effect.
