Abstract:
Objective To discuss the 3D reconstruction dual-source CT angiography (DSCT) in diagnosing nutcracker syn-drome,Methods 24 cases with known or suspected "nutcracker" syndrome were underwent with DSCTA and 3D recon-struction, left renal vein (LRV) were demonstrated and measured. Results Among 24 cases, 16 cases were diagnosed with "nutcracker" syndrome; the imaging demonstrated LRV were compressed. The angle between SMA and AO of 24 cases with "nutcracker" syndrome was abnormally acute(<45°). The angle A was 14°～38°, the average angle was 28.12°±7.92°. The angle A' was 11°～21°, the average angle was 16.46°±3.42°. Conclusion The 3D reconstruction DSCTA may be the most useful tool in diagnosing nutcracker phenomenon.
