256层螺旋CT肾动脉成像观察副肾动脉解剖结构

Anatomic observation of accessory renal artery by 256-slice spiral CT imaging

目的探讨256层螺旋CT血管成像技术(CTA)显示副肾动脉解剖结构的应用价值。方法收集115例行腹部动脉CT血管造影检查患者资料,记录每侧副肾动脉的有无、支数及其直径、长度和入肾部位,比较副肾动脉解剖特点的差异。结果副肾动脉有Ⅰ支型、Ⅱ支型及Ⅳ支型。左侧副肾动脉发现率>右侧,有统计学差异。男性副肾动脉发现率>女性,有统计学差异。副肾动脉的直径在性别及侧别的差异无统计学意义。在上下极不同部位入肾时差异有统计学意义,上极入肾者多见。结论256层螺旋CT可以清晰显示副肾动脉的解剖结构,为临床诊断提供更为简便、准确的辅助检查。

Objective To explore the application value of 256-slice spiral CT angiography(CTA) in displaying the anatomical structure of the accessory renal artery. Methods The data of 115 patients performed CT angiography of abdominal artery were collected. The number of branches, its diameter, length and location of the accessory renal artery were recorded. The differences of the anatomical characteristics of the accessory renal artery were compared. Results There were Ⅰ type branch, Ⅱtype branch andⅣ type branch in the collected accessory renal artery. There was statistical difference in the incidence of bilateral accessory renal artery, and the incidence of the left side was higher than that of the right side. There was statistical difference in the incidence of accessory renal artery between male and female, while the incidence of male was higher than that of female. There was no statistical difference in the diameter of accessory renal artery between the sexes and sides. There was significant difference between the upper and lower poles when entering the kidney, and the upper pole entering the kidney was more common. Conclusions 256-slice spiral CT can clearly and accurately display the anatomical features of accessory renal artery, which can provide a more simple and effective examination for clinical diagnosis.
