What is angiography

With the rapid development of modern medical technology, various advanced medical diagnosis and treatment technologies have emerged, providing solid protection for people's health. For example, angiography is a very common diagnostic instrument in major modern medical institutions. It can be used to diagnose diseases inside the body with outstanding results. But what is angiography? Let’s take a look at the explanation below. Those who are interested can find out more.

Contrast surgery is a surgery that uses the contrast effect of contrast agents to show visceral lesions.

Contrast agent classification:

① It is a contrast agent excreted by the kidneys and is mostly used for urinary and cardiovascular imaging;

② Contrast agents excreted through the liver and gallbladder, such as sulfamethoxazole;

③ Oil-based contrast agents, such as iodized oil and iodophenyl ester, are mainly used for contrast imaging of bronchial tubes, uterus, body cavities, etc.;

④ Solid contrast agents, such as barium sulfate, are mixed into a suspension and swallowed or given by enema for gastrointestinal imaging. The above four types of contrast agents have a higher density than human soft tissue and are collectively referred to as positive contrast agents, which appear white on X-ray films.

⑤ Gaseous contrast agents, such as air, carbon dioxide, oxygen, etc. The density of this type of contrast agent is lower than that of human soft tissue. It is a negative contrast agent and appears black on the X-ray film.

There is also a method to divide the density into two categories: high density and low density, but it is not as detailed and practical as the above classification, so it will not be explained in detail here.

X-ray angiography is a commonly used method of examination. At present, despite the development of computerized tomography (CT) which has a tissue and organ resolution capability 100 times stronger than ordinary X-rays, angiography remains an important auxiliary examination method.

Postoperative complications

1. Pain

After hysterosalpingography, many patients may feel mild abdominal pain, but this is tolerable. If the pain is unbearable, you need to go to the hospital immediately.

2. Bleeding

Normally there may be a small amount of bleeding after surgery, but the amount of bleeding is generally small and does not last more than 1 week. Heavy and prolonged bleeding is associated with damage to the uterus and fallopian tubes and genital inflammation.

3. Allergic reaction

Some patients may also experience allergic reactions after salpingography, mainly manifested in itchy skin on the face, chest, and back, hives, nausea and vomiting, and runny nose and tears.

4. Infection

Some hospitals may cause infections to patients due to lax disinfection. Therefore, when patients undergo hysterosalpingography, they must choose a regular hospital to avoid infection.
