What is it?

Nutcracker syndrome is a condition affecting the renal veins, usually the left one. In this syndrome, the vein is compressed and blood cannot flow normally in it and leave the kidney, causing the blood to flow back in the kidneys. There are several types of nutcracker syndrome, depending on the location of the compression. Causes for nutcracker syndrome may include pancreatic or abdominal wall tumors, nephroptosis, aortic aneurysm, rapid changes in height or weight, low BMI, enlarged abdominal lymph nodes, and pregnancy.
