To analyze the characteristics of anatomy and blood distribution of uterine arterial vascular network in vivo for healthy women aged 20-26 years by reconstructing the digital three-dimensional models based on computerized tomographic angiography (CTA) scanning technology.
From August to December 2012, a total of 25 female volunteers aged 20-26 years were recruited. All of them accepted CTA scanning. Their datasets were collected for reconstructing the digital three-dimension models of normal uterine arterial vascular network by using Mimics Version 10.01 software. After recognizing the supply arteries of each part of uterus, the three dimension models were divided into corpus and cervix arterial vascular network, left and right corpus arterial vascular network, left and right cervical artery vasc ular network and then calculated the proportion of vascular volume.
Digital three-dimension models of normal uterine arterial vascular network of 25 cases were successfully reconstructed, which clearly showed the structure of the uterine artery and its branches at all levels. Under normal physiological conditions, vascular network of corpus developed in 21 cases (84%, 21/25). In these cases, bilateral vascular network were developed and supplied by the ipsilateral uterine artery respectively, where the distribution of vascular were bilateral balanced in 18 cases and unilateral predominant in 3 cases.However, 4 cases (16%, 4/25) of vascular network of corpus were not developed. There were not statistically significant of vascular network volume between both sides of uterine corpus of 25 cases digital three dimension models of normal uterine arterial vascular network (t = 1.817, P = 0.077). The cervical arterial vascular networks didn't develop in 23 cases (92%, 23/25), whereas it developed in 2 cases (8%, 2/25).
This study successfully reconstructed the three dimensional models of uterine arterial vascular network for healthy females aged 20-26 years, confirming that the overall normal uterine vascular network distribution has the characteristics of bilateral, ipsilateral blood tendentious and balanced. But the cervical vascular network is rarely developing.
通过基于计算机断层血管造影（CTA）扫描技术重建数字三维模型，分析20 - 26岁健康女性子宫动脉血管网络的体内解剖及血液分布特征。
2012年8月至12月，共招募25名年龄在20 - 26岁的女性志愿者。她们均接受CTA扫描。收集其数据集，使用Mimics Version 10.01软件重建正常子宫动脉血管网络的数字三维模型。在识别子宫各部分的供血动脉后，将三维模型分为子宫体和宫颈动脉血管网络、左右子宫体动脉血管网络、左右宫颈动脉血管网络，然后计算血管体积比例。
成功重建了25例正常子宫动脉血管网络的数字三维模型，清晰显示了各级子宫动脉及其分支的结构。在正常生理条件下，21例（84%，21/25）子宫体血管网络发育。在这些病例中，双侧血管网络分别由同侧子宫动脉供血，其中血管分布双侧平衡的有18例，单侧占优的有3例。然而，4例（16%，4/25）子宫体血管网络未发育。25例正常子宫动脉血管网络数字三维模型的子宫体两侧血管网络体积差异无统计学意义（t = 1.817，P = 0.077）。23例（92%，23/25）宫颈动脉血管网络未发育，而2例（8%，2/25）发育。
本研究成功重建了20 - 26岁健康女性子宫动脉血管网络的三维模型，证实正常子宫血管网络总体分布具有双侧性、同侧血液倾向性及平衡性的特点。但宫颈血管网络很少发育。
