INCIDENCE AND EFFECT OF CAROTID ENDARTERECTOMY
|
Surgical Division of Saiseikai Central Hospital, Tokyo Kozo Ishitobi |
Reconstructive surgery was performed for 120 patients with occlusive arteriosclerotic lesions for the past 7 years. Fifty four out of 120 cases showed lesions in the carotid artery, of which one sixths (9 cases) involved the subclavian or aorto-iliac arteries. The age of the carotid arterial patients was 60±10 (M±S) and the total cholesterol was 218±52mg/di. They were younger than the aorto-iliac patients (68±6 years, 198±41 mg/dl). It is suggested that the hyperlipemia may be one of the cause of carotid occlusive disease.
Endarterectomies were performed on 51 cases and these cases were not only transient ischemic attack but also cerebral infarction in cases of severe stenotic lesions. The reconstructive surgery was tried on 12 occluded cases but the only 3 cases of them are restored carotid blood flow. The neurologic deficits by operation were occured in 3 cases from 35 cerebral infarctions, and no recurrence of TIA.
Pre-and postoperative cerebral blood flow (CBF) measurements by the N2O method showed the remarkable increase and CO2-reactivity (⊿CBF/⊿PaCO2) was also improved for the patients with severe carotid stenosis.
It is concluded that endarterectomy will indicate not only for the patients with TIA, but cases accompanied by cerebral infarction in stenotic carotid disease.
