Excerpt

Left renal vein entrapment syndrome, or nutcracker syndrome (NCS), is characterized by extrinsic compression of the left renal vein (LRV), most commonly between the aorta (Ao) and superior mesenteric artery (SMA), however anatomic variations might exist, and it might be underdiagnosed and undertreated. This entrapment syndrome restricts flow through the left renal vein, resulting in venous congestion and a host of symptoms. Nutcracker syndrome describes patients with characteristic symptoms associated with nutcracker anatomical morphology, whereas the nutcracker phenomenon describes the aorto mesenteric compression of the LRV while asymptomatic.
