摘要
目的:利用64层螺旋CT血管成像探讨主动脉后型左肾静脉解剖变异的类型及其临床意义。方法:回顾性分析500例患者的64层螺旋CT肾血管成像资料,观察主动脉后型左肾静脉解剖变异并进行分型。结果:主动脉后型左肾静脉解剖变异的发生率为7.2%(36/500),包括Ⅰ型(主动脉后左肾静脉)15例,Ⅱ型(环主动脉左肾静脉)17例和Ⅲ型(异常回流分支)4例。男性和女性主动脉后型左肾静脉解剖变异发生率差异无统计学意义。结论:64层螺旋CT血管成像可用于观察主动脉后型左肾静脉解剖变异,不同的变异类型对指导肾脏手术、肾脏移植及相关疾病的诊断有重要的临床价值。
Purpose： To evaluate the category and clinical significance of the variations on retroaortic trunk or branch of left renal vein with 64-slice spiral CT angiography.Methods： CT angiographies of 500 patients were retrospectively analyzed.The variations on retroaortic trunk or branch of left renal vein were observed and classified.Results： The incidence of the variations on retroaortic trunk or branch of left renal vein was 7.2%（36/500）including type Ⅰ（circumaortic left renal vein）in 15 cases,type Ⅱ（retroaortic left renal vein） in 17 cases and type Ⅲ（abnormal confluens branch） in 4 cases.No statistical difference of variation incidence of retroaortic trunk or branch of left renal vein was found between male and female.Conclusion： Anatomical variations on retroaortic trunk or branch of left renal vein can be observed with 64-slice spiral CT angiography.The different categories of the variations show clinical significance in the guidance for renal surgery,renal transplantation and the diagnosis of some correlated diseases.
