Patient with CAS of 50 percent should not undergo screening

(HealthDay)—A vascular surgeon and primary care physician agree that an asymptomatic patient with cardiovascular risk and stenosis of 50 percent on screening carotid ultrasonography should not undergo carotid artery stenosis ...

Why do older asymptomatic patients have carotid imaging

Most of the patients who had carotid revascularization for asymptomatic carotid disease were diagnosed on the basis of carotid imaging tests ordered for uncertain or inappropriate indications, according to a new study published ...

Risk of stroke at time of carotid occlusion

Preventing carotid artery occlusion (blockage) may not be a valid indication for stenting because the risk of progression to occlusion appears to be below the risk of carotid stenting or endarterectomy (surgical removal of ...

Almost one in 10 readmitted after carotid revascularization

(HealthDay)—Almost one in 10 Medicare patients undergoing carotid revascularization are readmitted within 30 days, according to a study published in the April 14 issue of the Journal of the American College of Cardiology.

Cerebrovascular reserve-based strategy is cost-effective

(HealthDay)—A decision rule based on assessment of cerebrovascular reserve (CVR) seems to be cost-effective for prevention of stroke in asymptomatic patients with carotid artery stenosis, according to a study published ...

CAS, CEA equally effective for long-term stroke prevention

(HealthDay)—For patients with high-grade carotid artery stenosis, carotid angioplasty and stenting (CAS) and carotid endarterectomy (CEA) are equally effective for long-term prevention of ipsilateral ischemic stroke, according ...

Endarterectomy

Endarterectomy is a surgical procedure to remove the atheromatous plaque material, or blockage, in the lining of an artery constricted by the buildup of soft/hardening deposits. It is carried out by separating the plaque from the arterial wall.

It was first performed on a superficial femoral artery in 1946 by the Portuguese surgeon João Cid dos Santos at the University of Lisbon. In 1951, E. J. Wylie, an American, performed it on the abdominal aorta. The first successful reconstruction of the carotid artery was performed by Carrea, Molins, and Murphy in Argentina, later in the same year.

The procedure is widely used on the carotid artery of the neck as a way to reduce the risk of stroke, particularly when the carotid artery is narrowed by more than 70%. A carotid endarterectomy may itself cause a stroke at the time of operation.

Endarterectomy is also used as a supplement to a vein bypass graft to open up distal segments.

Pulmonary hypertension caused by chronic thromboembolic disease (CTEPH) may be amenable to endarterectomy of the pulmonary artery. This is a highly specialized procedure.

The term atherectomy is used to describe reconstruction through a catheter.
