Summary

Acute kidney injury (AKI) is a common and serious complication after aortic dissection (AD), and it is closely related to the inflammatory response associated with cardiopulmonary bypass. Hemoperfusion can reduce the level of systemic inflammatory response effectively in patients with sepsis. Some studies have tried to apply hemoperfusion to cardiopulmonary bypass surgery, and put forward the concept of "absorptive cardiopulmonary bypass", but there are few related research reports. The use of hemoperfusion during cardiopulmonary bypass can reduce the level of systemic inflammatory response, thereby reducing the risk of postoperative AKI and improving the prognosis of patients. The Cardiovascular Surgery Department of the First Affiliated Hospital of Jiaotong University is one of the first demonstration units of "adsorption-type cardiopulmonary bypass" in China. Our previous retrospective analysis shown that intraoperative hemoperfusion can effectively reduce the occurrence of postoperative AKI in patients with AD, compared with traditional cardiopulmonary bypass. In addition, previous studies have found that the increased expression of CIRP after cardiopulmonary bypass can aggravate the oxidative stress and mitochondrial dynamics disorder in renal tubular epithelial cells, thereby inducing AKI. This project is a single-center randomized controlled study. It intends to investigate whether the application of hemoperfusion during cardiopulmonary bypass in patients with AD to reduce the level of systemic inflammatory response can reduce the incidence of postoperative AKI and improve the patient's discharge outcome. At the same time, exploratory studies were conducted to investigate whether hemoperfusion could effectively reduce the expression level of CIRP in the circulation. The successful implementation of this study can provide effective intervention methods and related theoretical basis for reducing the risk of AKI after aortic dissection.
