The efficacy of pharmacological preconditioning in carotid endarterectomy

OBJECTIVE: To assess the efficacy of pharmacological preconditioning with actovegin in carotid endarterectomy. MATERIAL AND METHODS: The study was based on the results of surgical treatment of 80 patients with hemodynamically significant uni- and bilateral lesions of carotid arteries. Half of the patients was operated immediately and others after pharmacological preconditioning with actovegin in dose of 1200 mg/daily during 1,5 months. RESULTS: Pharmacological preconditioning with actovegin increased the cerebral perfusion determined with one-photon emission computed tomography that improved significantly results of the surgery. There were significant changes in patient's state 7 days and 6 months after surgery. The improvement was correlated with the less number of asymptotic post-surgery ischemic strokes in different brain areas. CONCLUSION: A positive role of pharmacological preconditioning with actovegin in surgical treatment of carotid artery stenosis has been demonstrated.
