CASE 2 A 47-year-old female had received a liver transplant 8 months before presenting to our vascular and interventional radiology section with massive leg swelling and pain. The right internal jugular vein was catheterized using sonographic guidance. A pigtail catheter was advanced into the inferior vena cava. An inferior vena cavogram was performed revealing a high-grade stenosis of the inferior vena cava at the level of the upper surgical anastomosis (Fig. 2-1A). Pressure measurements obtained across the stenosis revealed a gradient of 26 mm Hg. Post-transplant inferior vena caval stenosis. The diagnostic catheter was exchanged over a rigid guidewire (Amplatz Super Stiff, Boston Scientific, Natick, Massachusetts) for an 18- × 20-mm angioplasty balloon catheter (XXL balloon dilation catheter, Boston Scientific, Natick, Massachusetts) that was used to dilate the lesion (Fig. 2-1B). Repeat cavography revealed minimal improvement (Fig. 2-1C), and the pressure gradient across the narrowed segment remained at 21 mm Hg. Due to the elastic recoil of the lesion, we elected to attempt stent insertion.
