What does ectopic pregnancy intervention mean?

Interventional therapy for ectopic pregnancy can be divided into three types, namely vascular interventional therapy, non-vascular interventional therapy and interventional therapy under ultrasound. For example, vascular interventional therapy is a process of destroying the gestational sac by using femoral artery puncture through thigh incision under local anesthesia, inserting catheter into uterine artery, injecting drugs and cutting off nutrient supply of gestational sac.
