摘　　要：目的探讨多层螺旋CT(MSCT)对胡桃夹综合征的诊断价值。方法对正常人和胡桃夹综合征患者行MSCT检查,分别对两组检查结果对比分析。结果胡桃夹综合征患者左肾静脉(LRV)受压狭窄程度较正常人明显;左肾静脉中心平面处肠系膜上动脉(SMA)与腹主动脉(AA)之间距离分别为(3.16±0.62)cm、(12.97±1.36)cm(P<0.05),差异有统计学意义;LRV左肾门处内径与最狭窄处血管内径比值(a/b)分别为(4.82±1.33,1.76±0.46)(P<0.05),差异有统计学意义;SMA与AA的夹角分别为(29.36±8.32)°,(49.97±11.85)°(P<0.05),差异有统计学意义。结论MSCT能精确地评价左肾静脉狭窄程度,有助于胡桃夹综合征的诊断。Objective： To explore the value of MSCT of multi - slice spiral CT in the diagnosis of Nutcracker phenomenon. Methods： Normal ponnal and Nutcracker phenomenon patients accepted MSCT examinations. The results of two groups were analyzed. Results： Stegnosis degree of left renal vein of the case group is severely than control group. The mean distance between SMA and abdominal aorta at the level of LRV was 3.16±0.62 and 12.97 ±1.36（P 〈 0. 05）, the mean angle of SMA and abdominal aorta was 29.36 ± 8.32 and 49.97 ± 11.85 （ P 〈 0. 05 ）, t he ratios of a/b of the mean distal unrestricted interdiameter and proximal restricted was 4.82 ± 1.33 and 1.76 ± 0.46 （ P 〈 0. 05 ）. There was statistically significant difference. Conclusions： The stegnosis degree of left renal vein was evaluated with MSCT, make for diagnosis of left renal vein entrapment syndrome.
