Diagnostic value of computed tomographic findings of nutcracker syndrome: Correlation with renal venography and renocaval pressure gradients

摘要: Abstract Purpose To evaluate the diagnostic values of CT findings nutcracker syndrome (NCS). Methods and materials Twenty seven subjects that underwent renal venography, were divided into three groups based on venographic renocaval pressure gradient (PG) collateral veins left vein (LRV): non-compensated NCS patients with PG ≥ 3 mm Hg (group 1, n = 12), partially compensated borderline PG (1  Results Beak sign LRV was found in 91.7% (11/12) group 50% (3/6) 2, 11.1% (1/9) 3 significant difference between 1 (P  Conclusion can be useful diagnosing NCS.
