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