A single-center experience of hemofiltration treatment for acute aortic dissection (Stanford type A) complicated with postoperative acute renal failure.

OBJECTIVE
To investigate the effect of continuous venovenous hemofiltration (CVVH) for aortic dissection patients with acute renal failure after surgery in retrospective manner.


METHODS
A total of thirty-seven aortic dissection patients with postoperative acute renal failure accepted CVVH therapy. The effect of CVVH was evaluated by analyzing clinical condition changes and laboratory examination results.


RESULTS
After treatment of CVVH, renal function and clinical symptoms were significantly improved in thirty patients. Eight of the thirty patients got completely renal function recovery within two weeks after CVVH therapy; and twenty-two of the thirty patients got completely renal function recovery within four weeks after CVVH therapy. Nevertheless, seven patients got no benefit from CVVH therapy with poor prognosis.


CONCLUSION
CVVH is an effective treatment to most aortic dissection patients with postoperative acute renal failure. The effect of CVVH was correlated with original renal function, early CVVH therapy, and continuous intensive care.
