背景:以往的影像诊断中,主要观察二维图像,随着医学科技的发展及诊疗设备的不断更新,在三维空间里研究人体内小血管的分布,已成为今后解剖学研究的必然.目的:利用聚乙烯醇-氧化铈血管造影对盆腔动脉进行三维重建,为血管介入提供可靠的解剖学依据.方法:纳入非妇科疾病死亡成人新鲜标本2例,预处理标本,经腹主动脉注入聚乙烯醇-氧化铈对比剂,用美国 QE Lights Speed VCT 64层 CT 连续扫描,利用 Mimics 软件进行三维重建.观察盆腔动脉的各级分支的出现以及管壁清晰度、饱满度.结果与结论:横断面原始图像及其三维图像重建均达到满意的效果,可清晰显示4级以分支,重建后的模型可以任意三维旋转.说明聚乙烯醇-氧化铈血管造影术是盆腔动脉进行三维重建的一种有效技术方法,对妇产科血管介入技术起指导性作用.

BACKGROUND: Two-dimensional images are observed in previous imaging diagnosis. With the development of medical technology and treatment equipment, the research on the distribution of smal vessels of the human body in the three-dimensional space has become necessary. OBJECTIVE: To explore three-dimensional reconstruction of pelvic arterial by polyvinyl alcohol-cerium oxide angiography in order to provide anatomic basis for interventional therapy with blood vessel. METHODS: Tow specimens of cavitas pelvis from voluntary adult cadavers without gynecological disease were included. The specimens were pretreated through perfusing polyvinyl alcohol-cerium oxide contrast agent, and scanned consecutively with CT (QE Lights Speed VCT 64, USA). Three-dimensional reconstruction of the artery of cavitas pelvis was made by Mimics with the CT data. The occurrence of pelvic arterial branches and the clearness and satiation of the vessel wal were observed. RESULTS AND CONCLUSION: Cross-sectional images and three-dimensional reconstruction images were al satisfied. Three-dimensional reconstruction models could show the fourth-grade pelvic arterial branch clearly, and the models could rotate in every direction. It indicates that polyvinyl alcohol-cerium oxide angiography is an effective means for the three-dimensional reconstruction of pelvic arteries, which plays a guiding role in obstetrics and gynecology vascular interventional technology.
