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 small 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 wall were observed. Results and Conclusion: Cross-sectional images and three-dimensional reconstruction images were all 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.
