Abstract:

Abstract：The incidence rate of vaginal intraepithelial neoplasia （VAIN） showed an upward trend in recent years.VAIN is caused by the infection of HPV with multi-focus and high recurrence rate.It always coexists with cervical intraepithelial neoplasia.It’s diagnosed by colposcopically-guided punch biopsy.The current treatments include medication （5-FU or imiquimod），laser and local resection.CO2 laser vaporization is effective，safe，minimally invasive，which can be applied in treatment of recurrent VAIN.

摘要：

阴道上皮内瘤变（VAIN）与高危型人乳头瘤病毒（HPV）感染相关，近年发病率逐渐上升，多与宫颈上皮内瘤变并存，复发率高，一般通过阴道镜下活检诊断。治疗有药物治疗（氟尿嘧啶或咪喹莫特等）、激光、局部切除术等，CO2激光气化治疗阴道上皮内瘤变安全有效、微创，可反复运用。
