Objective　To investigate the application of Dyna CT and Embolization Guidance technology in prostate artery embolism.　Methods　The data of 38 patients who underwent prostatic artery embolism were collected, in which images of digital subtraction angiography were acquired by SIEMENS Artis Zeego vascular examination. Dyna CT technology was applied to confirm the prostate arteries and the other collateral arteries, and Embolization Guidance was applied for the safety of prostate artery embolism.   Results   38 patients underwent prostate artery embolism by two high-seniority physicians. Dyna CT combined with DSA confirmed the prostate artery in 65 sides, with a ratio of 85.5% (65/76). Among them, bilateral prostate arteries were confirmed in 24 patients, and unilateral prostate arteries in 10 patients. 38 prostate arteries originated from the iliac artery, 11 from the obturator artery, 9 from the inferior bladder artery, 5 from the internal pudendal artery, and 2 from inferior rectal artery. Using Embolization Guidance technique, embolization was completed in 58 prostate arteries (89.2%, 58/65), in which 24 cases with complete bilateral embolism, 10 cases with complete unilateral embolism, 4 cases were failed because of vascular tortuosity.　Conclusion   Combined Dyna CT and Embolization Guidance technique can accurately confirm the origination of prostate arteries, and contribute to prostate artery embolization.
