| 目的 探讨多排螺旋CT(MDCT)对胡桃夹综合征(NCS)和胡桃夹现象(NCP)的诊断价值。方法 纳入2018年1月至2024年6月本院患者22例,其中NCS患者13例,NCP患者9例。评价CT平扫图像肠系膜上动脉(SMA)、左肾静脉(LRV)的可见性。在CT增强重建图像上测量主动脉SMA夹角(AMA)、LRV近段最宽处前后径(D1)、经AMA处前后径(D2)并计算D1/D2比值。结果 成人SMA、LRV在MDCT平扫图像上可见性较好。NCS组AMA、D1、D2、D1/D2分别为15.14°±3.54°,(11.00±2.38) mm,(2.76±0.43) mm,4.08±1.19;NCP组分别为22.42°±4.97°,(10.55±1.66) mm,(4.00±0.70) mm,2.70±0.53。两组AMA、D2、D1/D2存在显著性差异(P＜0.05)。结论 MDCT平扫可以提示或排除NCP、 NCS的诊断。MDCT增强成像可以全面评估腹部血管形态和LRV侧支循环,结合临床可确诊NCS。 |

| Objective To investigate the value of Multidetector CT (MDCT) scan in the diagnosis of Nutcracker syndrome(NCS) and Nutcracker phenomenon(NCP). Methods sTwenty-two patients were included in this retrospective study from January 2018 to June 2024. including 13 NCS patients and 9 NCP patients.The clinical manifestations and the CT features in different groups were analyzed.The visibility of SMA and LRV on unenhanced CT was evaluated.On the enhanced CT reconstraction images,the aortomesenteric angle(AMA),the anteroposterior diameter of the widest point of the proximal left ranal vein (D1),the anteroposterior diameter at the AMA (D2),and the D1/D2 ratio were measured. Result sSMA and LRV of adults are visible on unenhanced CT scan.The AMA,D1,D2,D1/D2 in NCS group(13 cases) were 15.14°±3.54°,11.00±2.38mm,2.76±0.43mm,4.08±1.19,and the NCP group were 22.42°±4.97°,10.55±1.66mm,4.00±0.70mm,2.70±0.53, respectively.There was a significant difference (P＜0.05) of AMA,D2,D1/D2 values between NCS group and NCP group. Conclusion Unenhanced MDCT is capable of suggesting or excluding the diagnosis of NCS or NCP,while enhanced MDCT can provide a comprehensive assessment of abdominal vascular morphology and the collateral circulation of the LRV, allowing for a difinitive diagnosis of NCS when combined with clinical information. |
