Surgical procedures can dramatically reduce your chances of suffering a stroke. McLeod Vascular Surgeon Dr. Joshua Sibille explains how he diagnoses pre-stroke conditions and the vascular procedures used to avoid an approaching stroke.
Here are highlights of Dr. Sibille’s presentation:
Carotid artery atherosclerosis results from plaque developing in the arteries. These plaques can partially or even completely block the artery. There are plenty of patients walking around with an occluded carotid artery that have no problems, because other arteries help carry the blood. But over time, small blood clots travel up to the brain. Even a small emboli that effects a portion of the brain can have significant and profound effects on anyone.
A carotid ultrasound is typically the initial screening study. It’s noninvasive, very easy. If an ultrasound comes back positive, some type of additional imaging is performed for more detail.
Patients, who have been screened and found to have carotid stenosis, benefit from treatment and significant stroke risk reduction if their stenosis is over 70 percent. Anything under that, you’re better treated medically because your risk of stroke is lower.
Patients, who have had a stroke or patients who are having TIAs or amaurosis, gain significant benefit from treatment, even if the artery is less than 50% clogged.
