Side effects of radiography in infants

Imaging technology is a medical technology that is widely used on the female body because it mainly targets the inside of the female ovaries and uterus, but it can also be used in other medical fields. When using imaging technology, contrast agents are implanted into the human body, and then X-rays are used to reflect the internal conditions of the human body. Some babies also undergo angiography, but what are the side effects of angiography for babies?

Side effects of salpingography contrast agents

1. Hysterosalpingography is a procedure in which contrast agents are injected into the uterus and fallopian tubes and monitored under the fluoroscopy of an X-ray machine. This will cause the body to be exposed to some x-rays. However, the damage caused by transient x-ray exposure is mild and reversible. When undergoing routine x-ray examinations, be sure to pay attention to protection, but there is no need to be afraid.

2. X-ray hysterosalpingography uses iodine contrast agent, 40% iodine has high density and good imaging effect, but it is very irritating and can cause severe abdominal pain after surgery. It sometimes causes chemical peritonitis. The examination time is long, the absorption is slow, and it is easy to cause foreign body reaction and form granuloma. If a large amount enters the vein, there is a risk of oil embolism. Aqueous contrast agent can avoid this situation.

Hysterosalpingography: It is a test method used to check whether the fallopian tubes of women are open. Hysterosalpingography is one of the most widely used methods in clinical practice.

Hysterosalpingography: X-ray hysterosalpingography is a method of injecting contrast agent into the uterine cavity and fallopian tubes through a catheter, using an X-ray diagnostic device to perform X-ray fluoroscopy and filming. Based on the development of the contrast agent in the fallopian tubes and pelvic cavity, it is used to understand whether the fallopian tubes are unobstructed, the site of obstruction, and the morphology of the uterine cavity.

Hysterosalpingography is a minimally invasive examination. Under the operation of an experienced physician and with the use of a digital X-ray machine, it can make a correct diagnosis of fallopian tube obstruction with an accuracy rate of 98%. It also has a certain therapeutic effect and is the most commonly used examination method to understand whether the fallopian tubes are unobstructed, the degree of patency, and the specific location of the blockage. In many aspects, it is irreplaceable by ultrasound, CT, MRI, hysteroscopy, laparoscopy, fallopian tube endoscopy, etc.

What is the salpingography procedure?

The first step is to dilate the vagina and expose the cervix. The cervix and fornix are disinfected with iohexol, the cervical catheter is filled with iohexol, the air in the tube is removed, the tube is inserted into the cervical canal along the direction of the uterine cavity, and the cervical clamp is tightened so that the conical rubber head of the catheter fits tightly against the cervix to prevent the drug from flowing out.

The second step is that during the hysterosalpingography examination, the patient lies on his back on the X-ray machine operating platform, routinely disinfects the vulva and vagina, then lays a sterile towel, and then checks the position and size of the uterus.

The third step is to observe the contrast agent flowing through the uterine cavity under X-ray fluoroscopy, and slowly inject iodized oil under fluorescent fluoroscopy. The first injection volume is 3~5ml. Observe its entry into the uterus and flow through the fallopian tube. At this time, a picture will be taken and then iodized oil will continue to be pushed in. Continue taking pictures after 5-10 minutes.

Step 4. Take another picture at the same location one day later, and observe whether there is free iohexol in the abdominal cavity. If both fallopian tubes are blocked, there will be no iodized oil in the pelvic cavity. If there is only a small amount of iohexol, it can be considered that the fallopian tubes are obstructed.
