Stent implantation across the ostia of the renal veins does not necessarily cause renal impairment when treating inferior vena cava occlusion.

摘要

The effect of inferior vena cava (IVC) stents crossing the ostia of the renal veins on renal function has not been reported. The purpose of this study is to report a single-institution experience with four cases of IVC stent implantation for malignant compression and/or invasion of the IVC causing severe lower-extremity edema. The patients' symptoms were successfully relieved, and follow-up imaging and serum creatinine measurements for the remainder of their lives revealed no evidence of renal impairment or renal vein thrombosis.
