Ectopic pregnancy occurs in the fallopian tube and can be treated with interventional therapy

Ectopic pregnancy occurs in the fallopian tube and is one of the common surgical acute abdomen. The fallopian tube interventional treatment method can preserve the fallopian tube and thus preserve fertility. There are two methods: vascular interventional treatment and non-vascular interventional treatment.

Indications

Ectopic pregnancy occurs in the fallopian tube and is not ruptured, the vital weight is stable, ultrasound examination shows that the adnexal mixed mass is less than or equal to 5CM, and the blood human chorionic gonadotropin is <20000IU/L. Vascular interventional treatment is suitable for patients who are more than 8 weeks pregnant, while non-hematogenous interventional treatment is suitable for those who are within 8 weeks of pregnancy.

Treatment Principle

1. Vascular interventional therapy: The blood supply of the fallopian tube tissue mainly comes from the fallopian tube branches branching off the ipsilateral uterine artery, which accounts for more than 85% of the blood supply. Therefore, inserting the catheter directly into the ipsilateral uterine artery and infusing embryocidal drugs can enable the drugs to quickly reach the fallopian tube branches, produce a first-pass effect, and achieve the purpose of quickly killing the embryo. After the infusion of embryocidal drugs, the uterine artery is often temporarily embolized, which can cause ischemia and necrosis of the gestational sac and prevent rupture and bleeding of the gestational sac, achieving good therapeutic effects.

2. Non-vascular interventional treatment: Insert the catheter into the fallopian tube through the cervix, puncture the gestational sac directly with a guide wire, and inject the drug solution. Due to the mechanical action of the hydraulic pressure, the drug solution can effectively penetrate between the fallopian tube wall and the trophoblast, promote the peeling of the trophoblast, cause cell necrosis and embryo death.

Efficacy

After the operation, clinical symptoms disappeared, human chorionic gonadotropin in the blood dropped to normal, and the pelvic mass shrank or disappeared.
