ABSTRACT
Objective To study the curative effect of continuous veno-venous hemodiafiltration(CVVH)in patients with acute renal failure(ARF)after aortic dissection surgery. Methods Fifteen patients with renal dysfunction following aortic dissection surgery underwent CVVH from Feb. 2002 to Dec. 2009 in this study.The clinical data of these patients were collected,such as heart rate(HR),central vein pressure(CVP),mean artery blood pressure(MAP),PaO2,renal function,perioperative manifestations and outcomes. Results Eleven patients survived but 4 died during the course of treatment. There were significant decreases of BUN,Creatinin after CVVH (P ＜ 0. 05)treatment,and the urine volume returned to nomal after CVVH in 6 -40 days. Conclusions CVVH is an effective,convenient and safe treatment for patients with severely ARF following aortic dissection surgery.
