Nutcracker syndrome is a medical condition where the left renal vein gets compressed between the aorta and superior mesenteric artery. This results in low blood flow and pressure in the left kidney. Some synonyms for this condition include Left Renal Vein Compression Syndrome, Nutcracker Phenomenon, and Renal Venous Hypertension Syndrome. These terms reflect the underlying causes and symptoms of the condition and can aid in diagnosis and treatment. Additionally, some medical professionals may also refer to nutcracker syndrome as mesoaortic compression syndrome or Wilkie's syndrome, which can further describe the specific anatomical or clinical characteristics of the disease.
