Even after demonstrated bilateral tubal occlusion during posthysteroscopic sterilization hysterosalpingogram (HSG), incorrect location of the micro-inserts can result in unplanned pregnancy and potential ectopic location.
More than 4 years after HSG-confirmed hysteroscopic tubal occlusion, a patient presented with pelvic both absenceboh absence cy test. Surgical and pathologic evaluation ultimately revealed an ectopic pregnancy of likely cornual location. Review of her HSG confirmed bilateral tubal occlusion, but the location of one micro-insert was incorrect.
Ectopic pregnancy after HSG-confirmed tubal occlusion is a rare event. Necessary measures to prevent this from occurring include not only confirmation of bilateral tubal occlusion, but also recognition of correct location of the micro-insert within the lumen of the fallopian tube. If the postprocedure HSG demonstrates incorrect micro-insert position, even in the absence of tubal dye spill, the patient cannot rely on this method for sterilization.
即使在宫腔镜绝育术后子宫输卵管造影（HSG）显示双侧输卵管闭塞的情况下，微插入物位置不正确仍可能导致意外怀孕和潜在的异位妊娠。
在HSG确认宫腔镜输卵管闭塞4年多后，一名患者因盆腔检查未发现任何异常前来就诊。手术和病理评估最终显示可能为宫角部位的异位妊娠。复查她的HSG确认双侧输卵管闭塞，但一个微插入物的位置不正确。
HSG确认输卵管闭塞后发生异位妊娠是一种罕见事件。预防这种情况发生的必要措施不仅包括确认双侧输卵管闭塞，还包括识别微插入物在输卵管腔内的正确位置。如果术后HSG显示微插入物位置不正确，即使没有输卵管造影剂外溢，患者也不能依赖这种方法进行绝育。
