输卵管内径测量在输卵管节育栓研制中的应用价值

目的:通过对输卵管内径的测量及分析,为输卵管节育栓的研制提供基础数据。方法:子宫输卵管数字减影血管造影(DSA)检查100例,应用GE公司AW4.3工作站进行输卵管内径测量和数据频数分析。结果:输卵管内口内径1.07±0.48mm,0.60～1.39mm频率最高(74.0%);间质部中段内径0.50±0.22mm,0.30～0.69mm频率占79.5%;间质部远端内径0.32±0.12mm,0.20～0.49mm频率占89.0%;峡部内径0.46±0.28mm,0.20～0.79mm频率占89.5%。结论:输卵管内径平均值及频数分布对输卵管节育栓的大小、形状的研制具有重要意义。

Evaluation of measuring inner diameter of fallopian tube on developing oviduct contraceptive plug

Objective：To provide the basic data for developing oviduct contraceptive plug by measuring the inner diameter of fallopian tube.Methods：The inner diameter of fallopian tube was measured and analyzed with the GE AW4.3 workstation in 100 women.Results：The diameter of internal orifice of the fallopian tube and its most high-frequency range（accounting for 74.0 percent）were 1.07±0.48 mm and 0.60-1.39 mm respectively;the diameter of middle section of the interstitial portion and its most high-frequency range（accounting for 79.5 percent）were 0.50±0.22 mm and 0.30-0.69 mm respectively;the diameter of distal section of the interstitial portion and its most high-frequency range（accounting for 89.0 percent）were 0.32±0.12 mm and 0.20-0.49 mm respectively;and the diameter of isthmic portion and its most high-frequency range（accounting for 89.5 percent）were 0.46±0.28 mm and 0.20-0.79 mm respectively.Conclusion：Measuring the inner diameter of fallopian tube and the frequency range is of great value in developing oviduct contraceptive plug.
