Inferior vena cava syndrome caused by postoperative positional changes in the liver.

Inferior vena cava (IVC) compression is well reported in the literature with the most common etiology being secondary to malignancy in neighboring structures (liver, kidney, pancreas, etc.). We present a novel case of IVC compression secondary to altered liver position following nephrectomy. This case report describes the clinical course, patient evaluation, and procedural considerations of this unique case.
