目的:评估血管内介入治疗子宫宫角妊娠的临床应用价值。方法:回顾性分析8例子宫宫角妊娠患者血管内介入治疗前后的临床资料,所有患者均行经股动脉穿刺双侧子宫动脉甲氨蝶呤灌注联合明胶海绵颗粒栓塞治疗。结果:8例患者均手术成功,成功率为100.0%。术后1例患者自行从阴道排出胚胎类似物,2例患者在B超下行清宫术,5例患者在腹腔镜下行宫角楔形切除术及输卵管单侧切除术,出血量均小于80 ml。1个月后复查,所有患者人绒毛膜促性腺激素(β-h CG)均完全降至正常水平。结论:子宫动脉化疗栓塞术作为子宫宫角妊娠术前治疗的重要辅助治疗方式,可有效提高B超监视下清宫术的安全性,减少腹腔镜下患侧宫角及输卵管切除术的术中出血量。 Objective: To evaluate the clinical value of endovascular interventional treatment of uterine horn pregnancy. Methods: The clinical data of 8 cases of uterine horn pregnancy before and after endovascular interventional therapy were retrospectively analyzed. All the patients underwent methotrexate perfusion by bilateral uterine artery perfusion of femoral artery and gelatin sponge. Results: All 8 patients were operated successfully, the success rate was 100.0%. After operation, 1 patient discharged embryo analogues from the vagina by himself, 2 patients underwent radical curettage by B ultrasound, 5 patients underwent laparoscopic wedge resection and tubal unilateral resection, the bleeding amount was less than 80 ml. One month later, all patients had a complete reduction of human chorionic gonadotropin (β-h CG) to normal level. Conclusion: Uterine arterial chemoembolization, as an important adjuvant therapy for preoperative uterine horn pregnancy, can effectively improve the safety of uterine curettage under B-ultrasound and reduce intra-operative bleeding during laparoscopic ipsilateral uterine horns and tubal resection the amount.
