Dyna CT与Embolization Guidance技术在前列腺动脉栓塞中的应用

目的探讨Dyna CT与Embolization Guidance技术在前列腺动脉栓塞中的应用。方法收集我科使用SIEMENS Artis Zeego数字减影血管造影机检查和图像采集进行前列腺动脉栓塞的38例患者,用Dyna CT技术明确前列腺癌供血动脉与其他侧支的情况,Embolization Guidance技术指导进行安全性的前列腺癌供血动脉栓塞。结果 38例患者经两名高年资主任医师指导分别进行前列腺癌动脉栓塞术。Dyna CT联合DSA确认前列腺动脉65侧,比例达85.5%(65/76),其中24例患者显示双侧前列腺动脉,10例确认单侧前列腺动脉;前列腺动脉开口起源于髂内动脉38条,起源于闭孔动脉11条,起源于膀胱下动脉9条,起源于阴部内动脉5条,起源于直肠下动脉2条。利用Embolization Guidance技术完成前列腺动脉栓塞89.2%(58/65),其中24例患者完成双侧栓塞,10例完成单侧栓塞,4例因血管迂曲不能进行超选择栓塞。结论 Dyna CT联合Embolization Guidance技术能够准确地显示前列腺优势供血动脉,在前列腺动脉栓塞治疗中具有重要的应用价值。

The application of Dyna CT with Embolization Guidance technology on the prostate gland artery embolization

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.
