PARAMETERS OF BLOOD OXYGEN CONSUMPTION IN POSTOPERATIVE BRACHYOCEPHALIC ARTERY RESTENOSIS

Keywords: atherosclerosis, brachiocephalic arteries, restenosis, oxygen consumption.
Abstarct: Objective – to study the parameters of blood oxygen consumption in restenosis development after reconstructive operation on extra-cranial basin vessels. Material and methods. 35 patients who undergone operations on stenosing atherosclerosis of brachiocephalic arteries including 10 patients with restenosis after reconstructive operations were examined. The rest 25 patients had no stenosis. The kinetics of blood oxygen consumption was studied by biological oxygen monitor and 2,2’-azobis (2-amidinopropane) dihydrochloride as free radicals initiator. Results and discussion. Carotid endarterectomy without alloplasty was performed in 22 (88 %) patients without restenosis. Carotid endarterectomy with alloplasty with postoperative restenosis was the primary operation in 7 patients (70 %). Statistically significant decrease of blood oxygen consumption on 40th minute was observed in patients with restenosis in comparison to the patients without restenosis. Strong direct correlation between oxygen consumption parameters and erythrocyte sedimentation rate in patients with restenosis was revealed. Conclusions. The selection of carotid endarterectomy with alloplasty was allowed to be a probable cause of postoperative restenosis of brachiocephalic arteries. The search for laboratory markers for the prediction of postoperative complications remains relevant.
