Nutcracker occurs when the left renal vein is compressed between the abdominal aorta and the superior mesenteric artery. When symptomatic (left flank pain, hematuria) it is called nutracker syndrome. If asymptomatic is called nutcracker phenomena. In this example, the patient had complaints of pelvic congestion only.
Renal vein stent placed for Nutracker Syndrome was placed too far into the IVC and causing pain. Stent was partially removed.
