| 目的 通过观测儿童正常肾动脉CT图像,得到不同年龄段儿童的肾动脉正常值。方法 选取腹部CT增强扫描检查无肾脏疾病及其他相关疾病的儿童284名,按年龄分为5组,观测肾动脉支数、肾动脉起始位置、肾动脉主干与腹主动脉下夹角、肾动脉起始处内径、副肾动脉数目、副肾动脉起源、副肾动脉入肾部位,并进行统计分析。结果 肾动脉以单支型最多见;右侧肾动脉高于左侧者较为常见;随着年龄增长,肾动脉起点与腹腔干距离逐渐增加(P＜0.05);肾动脉干与腹主动脉下夹角在不同组间差异无统计学意义(P＞0.05);各年龄组肾动脉干起始部内径的差异有统计学意义(P＜0.001),随年龄增长,肾动脉干起始部内径增加,不同性别及左、右肾间差异无统计学意义(P＞0.05);副肾动脉出现率为35.21% (100/284),主要起源于肾动脉(66/134, 49.25%)及腹主动脉(62/134, 46.27%),经肾上端(98/134, 73.13%)及肾下端(28/134, 20.90%)入肾。结论 本研究初步得到不同年龄儿童肾动脉的相关正常值,有助于诊治儿童肾动脉相关疾病。 |

| Objective To obtain the range of the normal renal artery using spiral CT in different age children. Methods A total of 284 children without kidney disease and related disease were examined with enhanced CT, and were divided into 5 groups according to age. The branch number and origin of renal arteries and accessory renal arteries, the original situation of renal arteries, renal artery trunk angles with abdominal aorta, renal artery trunk inner diameters, the place where the accessory renal arteries come into the kidney were observed and measured on CT images, and then analyzed statistically. Results The most common type in renal arteries was single renal artery. The right renal artery above the left was the most common. The distance between renal artery trunk and abdominal aorta increased with age (P＜0.05). There was no significant difference among the groups in the renal artery trunk angles with abdominal aorta (P＞0.05). The renal artery trunk inner diameter increased with age (P＜0.001), but no significant difference was found between the genders and the two sides (P＞0.05). The incidence of accessory renal artery was 35.21% (100/284). Accessory renal arteries mainly originated from renal artery (66/134, 49.25%) and abdominal aorta (62/134, 46.27%), and mainly passed into the upper polar (98/134, 73.13%) and the lower polar (28/134, 20.90%) of the kidney. Conclusion The data of this study based on image anatomy with regard to the pediatric renal artery are useful in the diagnosis and treatment of renal artery disease in children. |
