Typically four primary arterial routes provide oxygen to the brain. For the majority of people, connections between these four arteries permit one or more arteries to be completely blocked without affecting blood flow for the brain.

A temporary test for medical balloon occlusion is typically performed when there is an anomaly in an artery.

The test can determine whether the abnormal artery could be permanently or temporarily blocked without impacting blood flow in the brain. You can find more information about medicative balloon testing online.

A tiny catheter is inserted through an artery within the arm or groin and then passed through the head in the fluoroscopic direction. A balloon with a small diameter is placed on the end of the catheter.

Once it is in place within the artery of the head the balloon will be inflated. As the balloon is inflating, tests are conducted in the clinic. Every couple of minutes, tests are carried out to examine the grip of the hand's feet extension and flexion as well as memory, the language the facial expression, and orientation.

If a person has strong connections or collaterals other arteries can supply the flow of blood into the brain to ensure that there is no alteration in the function of the brain. In this scenario, the balloon is placed in place for 30 minutes before it is deflated and taken off.

In this case, the balloon is deflated immediately and then removed. After removal, blood flow is restored and the weakness disappears, typically within a matter of seconds.
