Spontaneous heterotopic pregnancies are rare, but with assisted reproductive techniques the incidence may approach 1:100. With the widespread use of transvaginal ultrasonography, physicians have attempted treatment of heterotopic pregnancies with minimally invasive procedures such as transvaginal guided potassium chloride (KCl) injection. However, there are few data on the success of this treatment.
A 30-year-old primigravida presented with a desired pregnancy and was found to have a tubal pregnancy in addition to an intrauterine pregnancy. Ultrasound-guided KCl injection into the heterotopic pregnancy was complicated by abdominal pain, surgical abdomen, and hemoperitoneum requiring salpingectomy.
A review of the literature revealed that 55% of tubal heterotopic pregnancies treated by KCl injection required subsequent salpingectomy. This raises concerns about the advisability of this treatment.
自然发生的异位妊娠很少见，但借助辅助生殖技术，其发生率可能接近1:100。随着经阴道超声检查的广泛应用，医生已尝试通过经阴道引导氯化钾（KCl）注射等微创方法治疗异位妊娠。然而，关于这种治疗方法成功的资料很少。
一名30岁初产妇因希望妊娠就诊，被发现除子宫内妊娠外还存在输卵管妊娠。在超声引导下向异位妊娠注射KCl后，出现腹痛、急腹症和腹腔积血，需要进行输卵管切除术。
文献回顾显示，通过KCl注射治疗的输卵管异位妊娠中有55%随后需要进行输卵管切除术。这引发了对这种治疗方法是否可取的担忧。
