RESUMO
BACKGROUND: The goal of this article is to present for the first time to the international community the detailed findings and outcomes of the Spanish Vascular Registry (SVR) after 16 years of experience. METHODS: We examined the nationwide registry promoted by the Spanish Society of Angiology and Vascular Surgery (1996-2011). The changes in vascular surgical activity in Spain during the period of study were examined. We evaluated the number of services, medical specialists, consultations, admissions, and operations that occurred in Spain. We also assessed the trends in therapeutic activity and the medical and social impact of vascular pathology. RESULTS: A mean of 60 centers (range = 32-83) participated in the SVR (79.3 % of the total). In the last year of the study period, 94.3 % centers (100 % of teaching centers) participated. The mean number of activities per hospital per year was 5,298 consultations, 2,625 vascular explorations, 630 hospital admissions (61 % elective and 31 % emergency), and 742 surgical procedures. A total of 29,289 carotid stenosis procedures had been registered over 16 years. Both carotid endarterectomy (CEA) and carotid artery stenting (CAS) procedures have increased in frequency over time. In 2011, CAS constituted 19.3 % of all carotid procedures. A total of 31,703 abdominal aortic aneurysm (AAA) operations were registered during the study period. Surgery for ruptured AAA remained stable over time. Since its appearance in the year 2000, endovascular treatment (EVAR) increased steadily over time. Currently, EVAR represents about half of all AAA surgery (50.2 %). The total rate of in-hospital operative deaths was 1.1 %, but in-hospital mortality for open arterial surgery was 4 %. Mortality has decreased of late. CONCLUSIONS: The SVR has enabled us to understand the development and implementation of vascular surgery throughout Spain and to note the increased healthcare activity and the better overall results obtained as a consequence.
