The carotid endarterectomy: experience with 260 cases and discussion of the indications.
During 1978 to 1989, 235 patients were operated upon with 260 procedures for cervical carotid endarterectomy. The patients were classified according to the presence or absence of ischaemic symptomatology, and for symptomatic patients, according to the reversibility or persistence of ischaemic symptoms. So the selection of patients was: reversible ischaemia 46%, stroke 29%, asymptomatic patients 25%. In the stroke group, no patient was operated on as an emergency, the endarterectomy was only performed after stabilization of the clinical state. Three subgroups were included in patients operated on for asymptomatic carotid stenosis: casual discovery 40%, treatment of the second carotid artery (previous endarterectomy for symptomatic contralateral stenosis) 34%, and treatment of the second carotid artery (previous ECIC by-pass for contralateral carotid occlusion) 26%. All patients were operated upon after angiographic exploration (femoral catheterisation in most cases), and after cerebral CT scan. The surgical technique included general anaesthesia, systematic shunting, endarterectomy after longitudinal arteriotomy, closure without patch. The operating microscope has been used since 1985. The surgical results were studied in terms of uneventful postoperative course (87%), reversible complications (8%) and long lasting complications (5%). The long lasting complications were of local origin (1%), of neurological origin (2%), of general origin (1%). Overall the operative outcome at 6 months was: return to previous clinical state 95%, neurological sequelae 2%, death 3%. In the patients operated on for asymptomatic carotid stenosis the overall outcome was: previous clinical state 97%, death 3%. The legitimacy of carotid endarterectomy procedure is discussed in relation to some recent pertinent literature.
