Long-term results of treatment of patients with hemodynamically signifi cant internal carotid artery stenosis and contralateral occlusion

Contralateral occlusion of the internal carotid artery (ICA) has often been considered a predictor of adverse outcomes in surgical interventions in the carotid basin. Analysis of the results of major international studies (NASCET and ACAS) confi rms this association. However, the number of patients with contralateral occlusion in the aforementioned studies was relatively small. Recently, specialists in endovascular surgery have been evaluating radiological surgical techniques (stenting, angioplasty) of the internal carotid artery as the safest methods of surgical treatment for patients with contralateral ICA occlusion. The aim of this study is to compare and analyze the results of carotid endarterectomy and ICA stenting in patients with contralateral occlusion, as well as to evaluate the impact of concomitant factors and medical history on the outcomes of surgical intervention.
