A 51-year-old male asked:
how do you establish cause and effect in carotid artery blockage stroke.?

Carotid disease: If angiogram was "fine" then you must not have any. The best way is to get a piece of the blockage in the carotid and look at it under a microscope. Most common cause would be vascular damage (rust) from smoking, high blood pressure, high lipids or old trauma. Happy to do 2nd Opinion to help narrow this down in you.
A 63-year-old female asked:
Can you fly if you have a carotid artery blockage, or is the cabin pressure and altiude too much that it can cause it to dislodge and cause a stroke?

Yes: The primary concern with a carotid blockage is not that the plaque will dislodge, but that the plaque will rupture, causing a blood clot to form on top which can then flow into the brain circulation and cause a stroke. There is no evidence that flying influences this process.
A 41-year-old member asked:
How reliable is ultra sound for detecting carotid artery blockage?

Excellent: Ultrasound duplex imaging of the cervical carotid arteries is very good at determining significant arterial narrowing. Changes in the flow patterns of the carotid arteries can also suggest disease in the internal carotid arteries further on in at the skull base even though the arteries themselves cannot be seen at that level.
Risk of stroke with 90% right carotid artery blockage?
