Nutcracker syndrome: diagnosis with Doppler US.

摘要: PURPOSE: To assess diagnosis of the nutcracker (renal vein entrapment) syndrome with Doppler ultrasonography (US). MATERIALS AND METHODS: US findings in 16 patients and 18 healthy control subjects were compared. The anteroposterior (AP) diameter peak velocity (PV) measured at hilar portion left renal (LRV) LRV between aorta superior mesenteric artery. RESULTS: mean AP diameters 10.0 mm +/- 2.0 (standard deviation) 1.9 1.0 (ratio, 5.0 2.3) patient group 7.2 1.8 2.3 0.6 3.3 1.1) group. PVs two locations 14.2 cm/sec 2.5 110.7 35.8 7.9 2.7) 18.6 3.7 50.9 27.9 2.8 1.5) Differences PV statistically significant groups (P < .01). CONCLUSION: ...
