目的:探讨应用影像的存储与传输系统(PACS)减少非离子型造影剂用量进行改良式子宫输卵管造影的可行性和有效性。方法:76例不孕妇女,其中39例行改良式子宫输卵管造影,37例对照组行常规子宫输卵管造影。改良式子宫输卵管造影先用3～6 ml造影剂经folly管充盈子宫后再以生理盐水10 ml加压推注造影剂由子宫进入输卵管再进入盆腔。对照组以同剂型造影剂行传统子宫输卵管造影。评估两种造影方法图像质量、诊断价值并记录两组造影方法的造影剂用量及造影术中及术后患者的疼痛。结果:数字化设备下改良式子宫输卵管造影有很好的诊断价值,图像质量与传统造影图像比较无差异(P>0.5),造影剂用量明显减少(P<0.001);10 ml生理盐水可成功推注造影剂由子宫经输卵管进入盆腔,造影术中及术后的疼痛较对照组明显减低(P<0.05)。结论:改良式子宫输卵管造影可减少造影剂用量,并能明显减轻疼痛,安全可行。
Objective: To investigate the feasibility and effectiveness of using a video storage and transmission system (PACS) to reduce the dosage of nonionic contrast medium for modified hysterosalpingography. Methods: 76 infertile women, including 39 cases of modified hysterosalpingography, 37 cases of control group underwent routine hysterosalpingography. Improved hysterosalpingography first with 3 ~ 6 ml contrast agent folly tube filled uterus and then saline 10 ml pressure bolus injection into the fallopian tube into the pelvis from the uterus. The control group with the same dosage of contrast agent conventional uterine tubal angiography. The two methods of imaging were evaluated for image quality, diagnostic value, and the amount of contrast media used for both methods of contrast imaging and the pain of patients during and after surgery. Results: The modified hysterosalpingography had good diagnostic value under digital equipment. There was no difference between the image quality and conventional contrast imaging (P> 0.5) and the dosage of contrast medium was significantly reduced (P <0.001). 10 ml of saline could be successfully pushed Injection of contrast agent from the uterus into the pelvis through the fallopian tubes, angiography and postoperative pain was significantly lower than the control group (P <0.05). Conclusion: Modified hysterosalpingography can reduce the amount of contrast agent, and can significantly reduce pain, safe and feasible.
