It is the beautiful wish of every woman to be a mother, and every mother-to-be who is eager to get pregnant will be ecstatic when she finds out that she is just pregnant, but not everyone can have a smooth and healthy baby, and there are all kinds of accidents that happen from the very beginning of pregnancy. The first thing you need to do is to get ready to get pregnant after getting married. At the beginning of October this year, Guan found that her period was late for more than ten days, so she hurried to do a test paper and found out that she was pregnant, and the whole family was happy to go to the hospital to do an early pregnancy test when the accident happened: no gestational sac was found in the uterine cavity! It is obvious that she is pregnant, but where is the baby? The doctor said that if it is not in the uterine cavity, then the possibility of ectopic pregnancy is very high, but the local ultrasound doctors repeatedly check, outside the uterine cavity also did not find the gestational sac. The doctor said that the gestational sac was probably too small to be detected, otherwise the gestational sac would grow larger in 1-2 weeks and then the ultrasound would be repeated. If there is heavy bleeding, come back to the clinic at any time. During this week, Guan only dared to lie in bed and did not dare to move. She was in tears every day at home and had trouble sleeping and eating. She was worried that if it was an intrauterine pregnancy, it would be fine, but I heard that if it was an ectopic pregnancy, it would grow further in the next two weeks and then it might need to be surgically removed and the fallopian tubes might have to be removed, which would make it even harder to get pregnant again. Should I risk waiting or should I take the medicine now to kill the embryo in the bud? What should I do? The family went to all the major hospitals to find out what to do when an acquaintance told them that the director of the ultrasound department of the Fourth Hospital of Harbin Medical University is an expert in obstetrics and gynecology and can not only determine the various pathologies of obstetrics and gynecology, but also has his own opinion on the treatment of diseases. The family rushed to make an appointment with the director for an examination, the routine scan section did not find any abnormalities, the director found a very small gestational sac in the right corner of Guan’s uterus with experience, which already had a fetal heart and small fetal buds. The director told Guan that although this pregnancy is not outside the uterus, but also belongs to a kind of ectopic pregnancy, the child is unable to grow, once the growth of the uterus will rupture, immediately terminate the pregnancy is necessary. The director helped Guan contact the best obstetrician and gynecologist at the Fourth Hospital and arranged for the patient to be hospitalized as soon as possible. As the patient had fertility requirements, the clinician took conservative treatment with systemic medication, but after a few days, the patient’s blood test index HCG remained high, and the obstetrician and gynecologist hurriedly sought help from Director Dong, who, although she was going to an overseas meeting soon, decided to arrange ultrasound-guided interventional treatment for the patient before going to the airport. The whole procedure was carried out under the real-time dynamic observation of ultrasound, and the main instrument of the director was only a puncture needle, which she accurately pierced into the gestational sac of only 25px in diameter with one needle. The whole procedure took less than 20 minutes. Three days later, the blood test index HCG dropped significantly, and after 2 weeks, the blood HCG returned to normal, and the lesion shrank significantly after several re-examinations. Guan’s family went home with peace of mind. Ectopic pregnancy is one of the common gynecological emergencies, with an incidence rate of about 1/100, and has been on the rise in recent years. It is one of the major causes of maternal mortality. It has a rapid onset and is life-threatening if not diagnosed and treated in a timely manner. The traditional treatment is open surgery, which is very traumatic, bleeding and painful for the patient, and the removal of the fallopian tube will reduce or lose natural fertility and bring mental pain to the individual and family. Therefore, it has become a clinical challenge to take effective measures to kill the embryo in time, avoid complications, and ensure the integrity and patency of the fallopian tubes as much as possible. Based on more than 20 years of experience in interventional treatment, the triple embedding method of interventional treatment for unruptured ectopic pregnancy, the first of its kind in China, was awarded the First Prize of New Medical Technology of Heilongjiang Provincial Health Department for its good efficacy. The cure rate after interventional treatment has reached more than 90%. The method is simple, accurate in positioning, fast and safe, with rapid postoperative blood HCG drop, remarkable efficacy and shortened treatment time. This technology is another leap forward in the development of modern medicine toward minimally invasive, non-invasive and harmless technology, especially for patients with ectopic pregnancy with fertility requirements, preserving the patient’s reproductive function and reducing the mental burden of patients and families.
