Summary

Postoperative acute kidney injury (AKI) is still one of the serious complications of thoracic aortic surgery, with incidence of 8 to 50 percent. Postoperative AKI significantly increases the morbidity and mortality of patients undergoing thoracic aortic surgery. Previous studies for AKI after DHCA reported confounding results due to different criteria of AKI. Therefore, the investigators tried to evaluate the incidence and risk factors of AKI after thoracic aortic surgery according to the diagnostic criteria and staging system of AKI reported from acute kidney injury network. The investigators also tried to develop a risk model with scoring system of AKI and evaluate the performance of the risk model.

Electronic Medical Record (EMR) Review

measurements of potential risk factors of acute kidney injury through the patients' previous medical record review. potential risk factors include previous history of hypertension, diabetes, cerebrovascular events, peripheral arterial disease, chronic obstructive pulmonary disease, recent myocardial infarction, coronary artery disease; preoperative glomerular filtration rate, preoperative creatinine level, preoperative cardiac ejection fraction reported on echocardiography, use of preoperative inotropics, use of deep hypothermic cardiac arrest, intraoperative colloid use, intraoperative blood product transfusion, total time of cardiopulmonary bypass,
