Iodine angiography is an X-ray hysterosalpingography with iodized oil as a contrast agent. Tubal iodized oil is injected into the uterine cavity and fallopian tube through the catheter to inject iodized oil contrast agent. X-ray fluoroscopy and radiography are performed by X-ray diagnostic apparatus. According to the development of contrast agent in the fallopian tube and pelvic cavity, the fallopian tube is unobstructed and blocked. A method of examination of the location and uterine morphology. If the fallopian tube is recanalized after the tubal ligation, it is necessary to understand the uterine fallopian tube to determine whether it can be operated.

Basic Information

Specialist classification: gynecological examination classification: X-ray

Applicable gender: whether men and women apply fasting: not fasting

Tips: The patient has a clean menstrual period of 3 to 7 days, banned sex life, banned bath and sexual life for two weeks after angiography, antibiotics can be given as appropriate to prevent infection. Normal value

The normal uterus is inverted triangle, the size is normal, the intima is smooth, the bilateral uterine horn extends outwardly on both sides of the fallopian tube, the fallopian tube is fully developed, the mucosa is smooth, and the movement is smooth and soft.

Clinical significance


1. Infertility: The disease is used to understand the cause of primary or secondary infertility. It can not only understand the presence of congenital malformations or pathological conditions in the uterus and fallopian tubes, but also understand whether the fallopian tubes are unobstructed and thus find infertility. the reason. In some cases, after uterine fallopian tube iodine angiography, it can promote the unobstructed fallopian tube to become fluent and conceive.

2. Abnormal uterine bleeding: Find the cause of abnormal uterine bleeding, understand the uterine mucosa and uterine cavity, and determine whether abnormal bleeding is caused by endometrial polyps or submucosal fibroids.

3. Fallopian tube recanalization: If the tubal is to be recanalized after ligation, it is necessary to understand the condition of the uterine fallopian tube to determine whether it can be operated.

4. Tumor observation: the effect of uterine fibroids, attached tumors and other pelvic organs on the uterine fallopian tubes.

5. Malformation diagnosis: uterine malformations such as double-horned uterus, mediastinal uterus, etc.

6. Foreign body diagnosis: Metal intrauterine device is ectopic.

7. Adhesion diagnosis: intrauterine adhesions, cervical adhesions, etc.


Preoperative preparation:

1. The patient's menstruation is clean for 3 to 7 days, and the sex life is forbidden.

2. Atropine 0.5mg can be injected intramuscularly half an hour before surgery to reduce tubal spasm.

3. The patient empties the bladder.

4. Ask if there is a history of iodine allergy. Iodine allergy test was performed half an hour before the angiography.

After surgery:

1. After the angiography, the bath and sexual life are forbidden for two weeks, and antibiotics can be given as appropriate to prevent infection.

2, sometimes due to the fallopian tube caused by the fallopian tube illusion, repeated if necessary.

3. A small amount of vaginal bleeding within one week after angiographic examination is normal if there is no other discomfort. If the amount of bleeding is more than the amount of menstruation or other discomfort, you should contact your doctor.

4, after the contrast examination is best to prevent contraception for three months, in order to reduce the possible impact of X-ray exposure. However, clinical observations have found that women who are pregnant in the month after angiography do not increase the risk of fetal abnormalities.

Inspection process

(1) The patient takes the bladder lithotomy position, routinely disinfects the vulva, vagina, and spreads the sterile towel to check the position and size of the uterus.

(2) dilate the vagina with a vaginal speculum, fully expose the cervix, disinfect the cervix and vaginal fornix again, and clamp the anterior lip of the cervix with a cervical clamp to explore the uterine cavity.

(3) If a metal catheter is used to fill the catheter with the contrast agent, the air is exhausted, and then the catheter is inserted into the cervix, and the external cervix is ​​blocked, so that the contrast agent is not overflowed, and the contrast agent is observed to flow through the uterine cavity under X-ray fluoroscopy. The fallopian tube condition and filming. In this period, it is best to take two shots. The first one is when the contrast agent is filled with the uterus and the fallopian tube. The contrast agent enters the pelvic cavity through the fallopian tube and takes a second part. For example, the contrast agent enters the pelvic cavity and diffuses. Taking a second shot, because the contrast agent enters the pelvic cavity will affect the accurate observation of the specific conditions of the fallopian tube, and then inject a certain amount of contrast agent, and then pull out the catheter and let the patient walk around properly. Wait for the contrast agent in the pelvis for 24 hours. Take the last delayed contrast film when it is fully diffused. The procedure for contrast imaging with a balloon catheter is generally the same as for a metal catheter. It is necessary to pay attention to the timing of the filming of the uterine fallopian tube iodine angiography. It is necessary to grasp the contrast agent flowing through the fallopian tube and keep a certain pressure during the flow of the contrast agent. Only in this way can the lumen be clearly understood. Specific fluency.

Not suitable for the crowd

Not suitable for people:

1. Acute and subacute internal and external genital inflammation.

2. Severe systemic diseases cannot tolerate surgery.

3. Pregnancy and menstrual period.

4. Postpartum, abortion, and chaos after 6 weeks of surgery.

5. Iodine allergies.
