ObjectiveTo analyze the results of 125 carotid endarterectomies under loco-regional
anesthesia, with selective use of shunt and bovine pericardium patch.MethodsOne hundred and seventeen patients with stenosis ≥ 70% in the internal carotid
artery on duplex-scan + arteriography or magnetic resonance angiography underwent
125 carotid endarterectomies. Intraoperative pharmacological cerebral protection
included intravenous administration of alfentanil and dexametasone. Clopidogrel,
aspirin and statins were used in all cases. Seventy-seven patients were males
(65.8%). Mean age was 70.8 years, ranging from 48 to 88 years. Surgery was
performed to treat symptomatic stenosis in 69 arteries (55.2%) and asymptomatic
stenosis in 56 arteries (44.8%).ResultsA carotid shunt was used in 3 cases (2.4%) due to signs and symptoms of cerebral
ischemia after carotid artery clamping during the operation, and all 3 patients
had a good outcome. Bovine pericardium patch was used in 71 arteries ≤ 6 mm in
diameter (56.8%). Perioperative mortality was 0.8%: one patient died from a
myocardial infarction. Two patients (1.6%) had minor ipsilateral strokes with good
recovery, and 2 patients (1.6%) had non-fatal myocardial infarctions with good
recovery. The mean follow-up period was 32 months. In the late postoperative
period, there was restenosis in only three arteries (2.4%).ConclusionCarotid artery endarterectomy can be safely performed in the awake patient, with
low morbidity and mortality rates.
