【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。更多还原

【Abstract】 Objective: To explore the value of MSCT of multi-slice spiral CT in the diagnosis of Nutcracker phenomenon.Methods: Normal pormal 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.更多还原
