Carotid endarterectomy in a community hospital surgical practice
1991
: Three hundred twenty-four carotid endarterectomies (CEAs) were performed on 303 patients over 5 years. Sixty per cent of the patients were symptomatic with completed stroke (36.4%), amaurosis fugax (35.4%) or transient ischemic attack (TIA) (50.5%). Some patients had multiple symptoms. Perioperative stroke occurred in four patients (1.2%) and 30-day mortality in five (1.5%). The combined stroke-mortality rate was 2.8 per cent. Other postoperative complications included TIA (1.9%), cranial nerve injury (3.1%), wound hematoma (6.5%), and hypertensive reperfusion syndrome (9.6%). Ten early reoperations were performed for wound hematoma (7) or technical problems (3). Follow-up of 284 CEAs (88%) at a means of 31 months revealed 33 late deaths, with two due to stroke. Late strokes occurred in 11 patients (3.9%). Five late strokes were ipsilateral (1.8%) and six were contralateral (2.1%) to the operated carotid artery. Ninety-seven carotid arteries were evaluated by duplex ultrasound scanning at a mean postoperative interval of 27.2 months. Ninety-two per cent had 0-30 per cent restenosis, 5 per cent had 40 per cent to 60 per cent restenosis and 3 per cent had 70 per cent or greater restenosis. The authors conclude that CEA can be performed with acceptable morbidity and mortality rates and that it is a durable operation that reduces the risk of late stroke.
