Four main arteries supply blood to your brain. In most people, there is a connection between these four arteries that allows one of the arteries to become blocked without significantly affecting the amount of blood reaching the brain.

A balloon occlusion test is usually done when there is an abnormality (such as an aneurysm or tumor) in one of the four main arteries.

This allows you to determine whether an artery can be temporarily or permanently blocked without significantly affecting the blood levels in your brain. Continue reading to know more about the best medical balloon development services.

What is included in the procedure?

The first balloon occlusion test involves an angiogram, which is an x-ray of the blood vessels to determine how well blood is moving through the vessels of the brain, lungs, abdomen, arms, or legs.

After photographing the blood vessels, a catheter with a small non-removable silicone balloon at the end is inserted from the femoral artery to the groin into the desired vein. This tube is inserted through the same hole as the other catheter, eliminating the need to reattach the artery.

After the balloon is placed in the artery to be tested, it is gently inflated to block flow through the artery. To keep blood from clotting when the flow stops, a dose of a blood thinner is given into the vein beforehand.

Clinical tests are performed while the balloon is being inflated. If you have good connections or collateral, the other arteries send enough blood to the brain so that brain function does not change.
