    Abstract:
    BACKGROUND: There are two equivalent in efficacy methods of the treatment of carotid artery stenosis: endarterectomy (CEA) and stenting (CAS), in which the blood flow increases in most patients by 20-40% over baseline, in some exceeding 100% and being symptomatic and leading to cerebral hyperperfusion syndrome (CHS). AIM: The aim of this study is to analyze the structure of neurological symptoms associated with CHS in patients with carotid artery revascularization. PATIENTS AND METHODS: Retrospective analysis included 1386 consecutive patients treated in the Department of General and Vascular Surgery between 2005 and 2011, with 625 of them were subjected to CEA and 761 to CAS. If neurological symptoms occurred, patients were consulted by a neurologist and ultrasonography (USG) examination and CT were performed. Neurological symptoms in patients with new onset of headache ipsilateral to the carotid revascularization were extracted from medical records and nursing documentation. RESULTS: Neurological symptoms attributed to CHS were observed in 66 (10.6%) of CEA and 61 (8.0 %) of CAS group. The frequency was similar in both groups (p = 0.43). The occurrence of epileptic attacks was similar in both study groups. The only difference was the less frequent falling of the lip in CAS group. Transient bradycardia and/or hypotension were observed in CAS (8.8% vs. 10.4% and 1.3% vs. 1.3%, respectively). No difference in stroke appearance between groups were found. CONCLUSIONS: The occurrence of neurological symptoms attributable to cerebral hyperperfusion syndrome after carotid artery revascularization in short term observation is similar regardless of the method used.
