目的 :研究介入插管治疗输卵管妊娠的方法 ,同时了解输卵管妊娠的X线影像改变。方法 :通过病史、B超及 β -HCG测定 ,对 34例临床确诊的输卵管妊娠病人在电视透视下 ,将微导管插入患侧输卵管先行造影 ,再注入氨甲蝶呤等药物进行治疗。结果 :其造影表现为患侧输卵管局部增粗、膨大、出现充盈缺损。通过血 β -HCG测定及B超判断疗效。本组病例一次插管成功率为91% ,治愈率为 85 % ,有效率为 94% ,不良反应为一过性腹痛 ,未产生其他并发症。结论 :采用介入放射插管治疗输卵管妊娠简单、安全、有效、且无损伤 ,术后可保留患侧输卵管功能。治疗成功的关键是术前早期正确诊断及熟练的插管技术 Objective: To study the method of interventional intubation for tubal pregnancy and to understand the X-ray image changes of tubal pregnancy. Methods: 34 cases of tubal pregnancy clinically diagnosed undergoing tubal angiography were treated with angioplasty by inserting the microcatheter into the affected tubal by angiography, B-ultrasound and β -HCG measurement. Results: The imaging showed ipsilateral tubal local thickening, swelling, filling defect. By blood β -HCG determination and B-judge effect. The success rate of intubation in this group of patients was 91%, the cure rate was 85%, the effective rate was 94%, adverse reactions were transient abdominal pain, did not produce other complications. Conclusion: The interventional radiotherapy for tubal pregnancy is simple, safe and effective, and has no damage. The tubal function of the affected side can be preserved after operation. The key to the success of the treatment is the accurate diagnosis of early preoperative and skilled intubation techniques
