RADPAD Glossary of Some Common Interventional Techniques
Radiology is the branch of medical science that has seen a major boost in the past few years. With more and more doctors learning interventional techniques for radiology, it has become important that you get familiar with some of the glossary terms related to this technology.
Central Venous Access
This is one method that is used to insert nutrients or blood in the blood vessels of the patient. The needle is inserted just beneath the skin and also used to provide medication of any kind to the patients.
Unlike in the past, interventional radiologists can easily pinpoint the area of internal bleeding with angioplasty. This has helped a lot in the operations that need to be performed after a person has sustained a severe accident. When the point of bleeding is discovered, the required blood clotting substance, gel, foam or tiny coils can be inserted with the help of a thin catheter that stop the bleeding.
One of the most effective methods to open up clogged arteries in the legs, brains, arms, kidneys or anywhere in the body is balloon angioplasty. A very small balloon is inserted into the vessel and inflated to open it.
Biliary Drainage and Stenting
Excess bile in the liver can cause problems; the biliary drainage method is used to extract it. A stent is a small mesh tube that is used to open up blocked ducts and allow the bile to drain out.
This is one of the superior X-ray exams that help in seeking out blockages and other blood vessel problems in the body. A catheter and a contrast agent (X-ray dye) are used to ensure the visibility of the artery.
Arteriovenous Malformations (AVM)
One of the biggest threats that can lead to internal bleeding and take lives is blood vessel abnormality. It can occur anywhere in the body. For this reason, arteriovenous malformations need to be treated properly. Interventional radiologists can treat this problem by inserting a catheter into the site of the bleeding.
This is the process through which the clotting agent is delivered directly to the bleeding area in cases like an aneurysm or a fibroid tumor in the uterus. The clotting agents are the coils, plastic particles, gels, foams, and other materials.
High Blood Pressure
The problem of renal hypertension occurs due to the narrowing of the arteries in the kidneys. This problem leads to an increase in blood pressure. It can be easily treated with angioplasty.
This is the tube that is inserted into the stomach of patients who are unable eat food usings their mouths.
Cancer is becoming curable, and the cancers of the endocrine system and the liver can be treated with this method. In this method of Chemoembolization, cancer-fighting agents are directly delivered to the site of the tumor of the cancer.
This is a great alternative to a surgical biopsy. The needle biopsy is used as a diagnostic test for breast, lung and other cancers.
