Disadvantages of 4D hysterosalpingography

Four-dimensional ultrasound salpingography is a technology that determines whether the fallopian tubes are unobstructed. It involves inserting a double-lumen tube into the uterine cavity and then injecting contrast agent, which can show the health of the uterus, fallopian tubes, pelvic cavity and other parts. But what are the disadvantages of four-dimensional hysterosalpingography? It will mainly cause some infection, and women may experience uterine bleeding and abdominal pain after the examination.

Hysterosalpingography itself is a traumatic examination and may increase the risk of infection, so it is generally not considered as the primary examination item.

1. Effect of 4D salpingography

1. Determine whether the fallopian tube is unobstructed

Contrast agent is injected into the uterine cavity and fallopian tubes through a catheter, and films are taken under X-ray. Based on the development of the contrast agent in the uterine cavity and fallopian tubes, it can be determined whether the fallopian tubes are unobstructed, the type of fallopian tube lesions, the location of the lesions and their severity.

2. Evaluate the success rate of surgery

Through angiography, we can know the type of fallopian tube lesions, the location of the lesions and their severity. We can also know the method and location of the sterilization surgery and the current health of the fallopian tubes, so as to evaluate the success rate of fallopian tube dredging and repair.

Second, the advantages of four-dimensional hysterosalpingography

1. The false positive rate of four-dimensional ultrasound diagnosis of fallopian tube patency is low and the accuracy is high;

2. Ultrasound does not cause radiation damage and will not harm ovarian function;

3. Ultrasound angiography can simultaneously evaluate the morphological structure and egg-collecting function of the fimbria of the fallopian tube (whether the egg can be caught by the fimbria of the fallopian tube after being discharged from the ovary), while iodized oil angiography cannot;

4. Ultrasound angiography has a certain therapeutic effect in dredging the fallopian tubes;

5. Ultrasound contrast agents can be absorbed in a short time and are not allergic, while iodized oil may cause allergies;

6. Since ultrasound contrast agents have good permeability, the pain is mild;

7. You can prepare for pregnancy 3 months after X-ray angiography, and you can prepare for pregnancy within 7 days after ultrasound angiography (after the small amount of bleeding during angiography has cleared up);

8. The accuracy of ultrasound angiography in diagnosing intrauterine adhesions, scars, polyps, myomas, deformities, etc. is much higher than that of X-ray angiography;

3.4D hysterosalpingography population

1. For women who have been trying to get pregnant for more than one year but have not gotten pregnant: Check whether the fallopian tubes are unobstructed and whether infertility is caused by fallopian tube problems.

2. Women with a history of ectopic pregnancy or miscarriage: Check whether the ectopic pregnancy is caused by fallopian tube disease, and whether the miscarriage causes fallopian tube blockage, adhesion or water accumulation.

3. For women who have had medical abortion: Check whether the abortion caused fallopian tube disease.

4. Women who have undergone fallopian tube sterilization surgery: Check the specific location of the cut/severed fallopian tube and the damage, evaluate the success rate of the repair, and prepare for the fallopian tube repair surgery.

5. For women who have not become pregnant one year after fallopian tube surgery: Check the recovery of the fallopian tubes and confirm whether adhesions and blockages occur again.
