摘要
目的:选用64排MSCT、1.5T MRI增强扫描方法,探讨主动脉后型左肾静脉(Retroaortic left renal vein,RLRV)患者的影像学征象及诊断价值。方法:1、回顾性收集10例2018年01月-2020年10月期间泉州医学高等专科学校附属人民医院经MSCT、MRI增强扫描诊断为RLRV的患者为A组,并选择40例左肾静脉(Left Renal Vein,LRV)正常走行者为B组,测量A、B组患者横断面LRV近肾门段最大前后径(a1)、腹主动脉段最小前后径(a2)、a1/a2比值、性腺静脉扩张发生率、泌尿系统症状出现率;两组进行统计学分析。2、将A组分成两组(包括A1后胡桃夹综合征组、A2后胡桃夹现象组),对LRV横断面近肾门段最大前后径(a1)、夹角段最小前后径(a2)、a1/a 2比值、性腺静脉扩张发生率、泌尿系统症状发生率,两组进行统计学分析。结果:1、A组与B组比较结果:LRV腹主动脉段最小前后径(a2)、a1/a2比值、性腺静脉扩张发生率、泌尿系统症状出现率有统计学意义。2、A1组与A2组比较结果:LRV近肾门处最大前后径(a1)、腹主动脉段最小前后径(a2)、a1/a 2比值、泌尿系统症状出现率有统计学意义。结论:MSCT、MRI增强扫描技术对发现RLRV以及诊断后胡桃夹综合征具有很大的临床价值。
Objective:MSCT、1.5 T MRI enhanced scanning method was used to study the imaging features and diagnostic value of patients with Retroaortic Left Renal Vein.Methods:1、Rretrospectively collected 10 cases of 2018.01~2020.10 range"Quanzhou Medic-al College People’s Hospital Affiliated"by MSCT and MRI enhancement scanning in the diagno-sis of arterial type after the LRV of patients in group A,40 cases of left renal vein Norm-al walkers are B groups.The cross-sectional LRV of A、B group were measured:the maximum anterior and posterior diameter(a1),the abdominal aortic segment minimu-m anteroposterior diameter(a2),the ratio of a1 to a2,the incidence of gonadal venou-s dilatation,and the incidence of urinary symptoms;The two groups were compared an-d statistically analyzed.2、Group A will be divided into two groups(including A1:Post-erior Nutcracker Syndrome;A2:Posterior Nutcracker Phenomenon),The cross-section-al LRV of A、B g-roup were measured:the maximum anterior and posterior diamete-r(a1),the minimum anterior and posterior diameter(a2),the ratio of a1 to a2,the i-ncidence of gonadal venous dilatation,and the incidence of urinary symptoms;The t-wo groups were sta-tistically analyzed.Results:The abdominal aortic segment minimu-m anteroposterior diameter(a2),a1/a2 ratio,the incidence of gonadal venous dilatati-on and the incidence of urinary system symptoms were statistically significant.The re-sults of 2.A1 group and A2 group were as follows:the maximum anterior and poste-rior diameter(a1),The abdominal aortic segment minimum anteroposterior diameter-(a2),the ratio of a1 to a2,and the incidence of urinary system symptoms were statist-ically significant.Conclusion:MSCT and MRI enhanced scan-ning are of great clinical va-lue in detecting the variation of RLRV and Posterior Nutcracker Syndrome.
