ABSTRACT
A 62-year-old woman was referred to our hospital for treatment of hemolytic anemia 10 years after total arch replacement for acute aortic dissection. The cause of hemolysis was confirmed to be mechanical damage of red blood cells at the kinked graft. Because aortic valve regurgitation and occlusion of the left subclavian artery were also found, resection of the kinked graft, aortic valve replacement and reconstruction of the left subclavian artery were carried out concomitantly at reoperation. Her postoperative course was uneventful, and hemolysis resolved soon after the operation.
ABSTRACT
Objective: To analyze the risk factors on acute respiratory dysfunction caused death in patients after type A aortic dissection surgery. Methods: A total of 223 patients who received aorta replacement surgery in our hospital from 2010-01 to 2012-12 were retrospectively studied. 80 patients suffered from post-operative acute respiratory dysfunction including 61 male and 19 female with the mean age of (49.2 ± 11.6) years. Those patients were divided into 2 groups as Death group, n=18 and Survival group, n=62. We analyzed the most relevant risk factors for death, such as gender, age, histories of smoking, diabetes, hypertension, Marfan syndrome;pre-operative acute or chronic dissection, hypoxemia, mal-perfusion, LVEDD and LVEF;CPB time, aortic-clamping time;post-operative ICU retention time, mechanical ventilation time, permanent neurologic dysfunction, pulmonary infection, MACE, renal failure, hypohepatia, septicemia and wound mal-healing, et al. Results: The early post-operative ( Conclusion: The occurrence and mortality were high in patients after type A aortic dissection surgery especially in those with female gender and post-operative renal failure.
