Is surgery for blocked carotid artery dangerous?

Carotid surgery. Carotid surgery should be done when risk of not doing so higher. Stroke risk lowest for asymptomatic stenosis, higher in those with TIAs and yet higher with prior stroke. Risk of MI can be higher than stroke risk. Slight risk of bleeding, real but low risk cranial nerve injury, low risk of surgically significant carotid renarrowing. Generally stroke risk lower for surgery, MI risk lower for stent.

My grandfather had a stroke. His carotid arteries are 100% and 85% blocked. What kind of surgery does he need?

Depends. We do not perform surgeries to open up complete (100%) blockages. For the side with 85% blockage he should first and foremost be on an Aspirin as well as a cholesterol lowering statin medication for optimal medical management. The surgical options are an open carotid endarterectomy or a carotid stent. If he can tolerate anesthesia then an open procedure is preferred. Read more...

I have some blockages in my carotid arteries and will probably have to have surgery. Is this a very dangerous operation?

Not really. If it has been decided that you need a carotid endarterectomy, then it will be safer to have the surgery than not. The goal is to minimize the risk of stroke. The risk of a stroke or heart attack during a carotid endarterectomy is typically < 3%. If you have had a TIA or stroke and have a carotid blockage >50%, or no symptoms and a blockage >80% then surgery i safer than no surgery. Read more...

My father is 80 years old and one of his carotid arteries is 90% blocked - is he a good candidate for surgery or not?

Possibly. It depends on his general health especially the condition of his heart and lungs. The surgeon must report no more than a 3 - 5% complication rate. He may be a candidate for a stenting procedure if he has heart problems or multiple strokes. Read more...
