Abstract (EN): Introduction and objectives Which is the best carotid stenosis treatment remains a controversial issue. To present day, no study has compared the results of carotid artery stenting versus carotid endarterectomy in Portugal. We aim to provide real life numbers regarding the outcomes of both procedures in Portuguese public hospitals. Methods Every patient registered between 2005 and 2015 with the main diagnosis of carotid stenosis and submitted to carotid endarterectomy or carotid artery stenting was included. The information was obtained through the Central National Healthcare Administrative database, a mandatory registry for hospital refunding. Primary outcomes were hospital mortality and stroke. Patient demographics, comorbidities and hospital length of stay were also evaluated. Results The study included 6094 patients: 1399 were symptomatic (mention of prior stroke) and 4695 asymptomatic. Carotid artery stenting was performed on 22% of the symptomatic and 18% of the asymptomatic patients. In the symptomatic patients, the in-hospital mortality was significantly higher in those submitted to stenting (3.6% vs. 1.6% in carotid endarterectomy, p = 0.025). No significant differences in outcomes were observed in the asymptomatic group (mortality 0.9% vs. 0.8%, p = 0.852; stroke rate of 2.6% vs. 2.3%, p = 0.652 - carotid artery stenting vs. carotid endarterectomy). In both groups, there was an important increase in the proportion of stenting between 2005 and 2012, followed by a gradual decline until 2015. Conclusion Despite its increasing frequency, a higher early mortality was documented for CAS in symptomatic patients. No worse outcome was observed in asymptomatic patients.
