Death and disabling stroke occur more often in symptomatic and asymptomatic patients at high risk for stroke who have not been treated with carotid endarterectomy surgery. A well-respected study, the North American Symptomatic Carotid Endarterectomy...
Trial (NASCET), along with a corresponding European study (ECST), showed that death or disabling stroke are reduced by 48% among those with severe stenosis (greater than 70%) when they undergo carotid endarterectomy surgery. In patients with less severe stenosis (50–69%), endarterectomy was shown to reduce risk by 27%. Patients with less than 50% stenosis were actually harmed by surgery, increasing the risk of death or disability by 20%. The conclusion of the study was that death and disability could be reduced overall if carotid endarterectomy was performed only on patients with the more severe stenosis who are also surgically fit, and that that the procedure should be performed only by surgeons whose complication rates are less than 6%.

Once these are explained, carpal tunnel syndrome is described and one way in which carpal tunnel surgery is performed to correct the problem.
In a carotid endarterectomy, the carotid artery is access through an incision in the neck (A). A measurement of the pressure inside the vessel is taken to assess the degree of blockage (B). The carotid is clamped above and below the incision, and a shunt is inserted to maintain blood flow (C). Plaque lining the artery is removed (D). The shunt is taken out (E), and the incisions are repaired (F). (Illustration by GGS Inc.)

Other Information
Carotid endarterectomy (CEA) is a surgical procedure used to correct carotid stenosis (narrowing of the carotid artery lumen by atheroma), used particularly when this causes medical problems, such as transient ischemic attacks (TIAs) or cerebrovascular accidents (CVAs, strokes). Endarterectomy is the removal of material on the inside (end-) of an artery. Angioplasty and stenting of the carotid artery are undergoing investigation as alternatives to carotid endarterectomy.
