ratelena [41]

To determine whether the addition of carotid endarterectomy to aggressive medical management can reduce the incidence of cerebral infarction in patients with asymptomatic carotid artery stenosis.

<h3>What is Endarterectomy?</h3>

An endarterectomy is a surgical treatment used to clear an artery's lining of an atheromatous plaque obstruction caused by an accumulation of deposits. The procedure involves removing the plaque from the artery wall.

A Portuguese surgeon named Joo Cid dos Santos initially conducted it on a subsartorial artery in 1946 at the University of Lisbon. American E. J. Wylie carried it out on the abdominal aorta in 1951. Later that year, in Argentina, Carrea, Molins, and Murphy completed the first successful repair of the carotid artery.
