Nutcracker syndrome leads to which venous finding?

Nutcracker syndrome leads to which venous finding?

• A. Renal vein thrombosis and renal venous congestion
• B. Hepatic venous outflow obstruction
• C. Portal vein thrombosis
• D. IVC obstruction

Answer: (A)

Nutcracker syndrome happens when the left renal vein is squeezed between the aorta and the superior mesenteric artery. This compression raises pressure in the left renal vein and its upstream branches, creating renal venous hypertension and congestion. That increased venous pressure often leads to dilation of the left renal vein and can contribute to thrombosis if flow becomes sluggish, so renal vein thrombosis and renal venous congestion are the classic vascular findings you’d expect with this condition. The other options point to issues in different venous systems (hepatic veins, portal system, or the IVC) that aren’t directly affected by the left renal vein compression in Nutcracker syndrome.
