What is Nutcracker Syndrome?

Compression of the Left Renal Vein and Its Effects

Nutcracker syndrome is a rare and often difficult-to-diagnose condition. It is essentially defined as the compression of the left renal vein over time between the superior mesenteric artery and the aorta.

This compression leads to the pooling of blood in the reverse direction. Subsequently, this pooled blood may leak from the kidneys and through the urinary tract. This process can set the stage for problems that can lead to anemia.

The key point here is that the disease itself does not directly cause anemia. However, it is stated that anemia can occur due to the escape of pooled blood in the urine.
