[Renal function after aortic reconstruction for aortic dissection: special reference to the renal blood flow from...

Relationships between preoperative renal blood flow and postoperative renal dysfunction after aortic reconstruction for aortic dissection of DeBakey I and IIIb type were discussed. The incidence of renal dysfunction after surgery was not so high and renal failure was transient. Renal dysfunction occurred in the cases with true lumen oppressed by false lumen at chronic stage. Sometimes, abnormal findings were showed in CT scanning and/or renogram even in serum creatinine or BUN value was normal. In conclusion, our data showed justification of anastomosis of distal artificial graft to true lumen in acute stage. But in chronic stage, it is very important in point of selection of operative method to recognize how renal blood flow was preserved and to know the location and size of reentry before surgery.
