The treatment is as follows: first, the diagnosis is confirmed by an obstetrician, and after the preoperative preparation, the patient goes to the catheterization room to receive interventional therapy. First, a catheter was introduced through femoral artery puncture for uterine arteriography to show the lesion, then methotrexate was injected into the uterine artery, and finally the uterine artery was embolized with gelatin sponge particles. The patient was discharged from the hospital after a few days of observation in the ward. Regular follow-up after discharge is done until beta-HCG (chorionic gonadotropin) returns to normal. Tubal pregnancy is the most common type of ectopic pregnancy, and the detection rate is increasing with the popularization of ultrasound and other means of examination. The traditional treatment for this type of patient is intramuscular or intravenous methotrexate, laparoscopy, and open surgery. Intravenous drugs have narrow indications, relatively poor therapeutic effect, and there is a possibility of hemorrhage in the process of treatment, and open surgery is more traumatic and generally only applicable to emergency patients who are difficult to stop bleeding. Currently, minimally invasive technology is the main treatment method. Vascular intervention is an emerging minimally invasive technology, the technology only in the thigh root incision of about 2 millimeters can complete the treatment of this disease. The drug concentration is increased by injecting the drug directly into the artery supplying blood to the gestational sac, and the necrosis of the gestational sac is further accelerated by arterial embolization. Due to the embolization of the uterine arteries, the problem of tubal rupture and bleeding during the conservative treatment of the drug does not usually occur. It has the advantages of leaving no scar on the body surface, safety, high efficacy and fast recovery, which is worthy of clinical promotion. It is a good choice for patients with repeated tubal pregnancies who still want to have children (especially those who have had one fallopian tube removed) and don’t want to have a scar on their abdomen, and it is also suitable for unmarried patients with tubal ectopic pregnancies who want to have children.
