In patients with Nutcracker syndrome, what symptom is often present?

In patients with Nutcracker syndrome, flank pain is often a prominent symptom due to the compression of the left renal vein as it passes between the aorta and the superior mesenteric artery. This compression can lead to various symptoms, primarily related to the kidneys and the lower abdomen. The left renal vein becomes engorged due to increased venous pressure, which can cause pain in the flank region. Additionally, patients may experience other symptoms due to the potential for renal vein entrapment, but flank pain is a common and significant indicator of this condition.

Other symptoms like palpitations, joint pain, or chest pain are not typically associated with Nutcracker syndrome, as they relate to different physiological processes and conditions that do not involve the specific vascular abnormalities present in this syndrome. Flank pain remains a key clinical marker linking this condition to its characteristic vascular compression effects.
