How do you test for occlusion?
Uson testers can conduct occlusion tests by using a pressure drop technique. In this test, the product must drop below a preset pressure (reject level) to pass the test; the opposite of a normal integrity test. The same basic pneumatic circuit employed in pressure decay testing is used in occlusion testing.

To perform a traditional angiogram, a doctor inserts a long, narrow tube called a catheter into an artery located in the arm, upper thigh, or groin. They will inject contrast dye into the catheter and take X-rays of the blood vessels. The contrast dye makes blood vessels more visible on X-ray images.
What can happen if your carotid artery is blocked?
If the narrowing of the carotid arteries becomes severe enough that blood flow is blocked, it can cause a stroke. If a piece of plaque breaks off it can also block blood flow to the brain. This too can cause a stroke.
How do you fix a blocked carotid artery?
Carotid endarterectomy, the most common treatment for severe carotid artery disease. After making an incision along the front of your neck, the surgeon opens the affected carotid artery and removes the plaques. The artery is repaired with either stitches or a graft.
