Introduction: Acute aortic dissection is a complex pathology with high morbidity and mortality that requires an effective health system with a skilled and available team. Brazil’s vast territory and its socio-economic differences may have an impact on the diagnosis, treatment and prognosis of this disease. Objective: To describe the statistical behavior of AD available in the Brazilian public health system database (DataSUS). Materials and Methods: An observational, retrospective, aggregate, descriptive and documentary study of secondary data extracted from the SUS Hospital Information System (SIH/SUS), available in the DataSUS database from 2008 to 2023, of patients with type B aortic dissection. Type A dissections were excluded. Results: 4325 authorizations for hospital admissions and 1342 deaths for dissection repair were recorded. The Southeast had the highest total number of hospitalizations due to the procedure (49%), while the South had the highest prevalence (0.235 per 100,000 inhabitants). The average number of days spent in hospital was 12.6 days. In terms of total expenditure, 36.38% of these were elective admissions, while 63.60% were emergency admissions. In both cases, the Southeast was the region that paid the most, accounting for 56.83% of the national amount in elective cases and 44.38% in emergency cases. The average dollar amount spent on this procedure during this time series was $2,596.94, of which $2,529.66 on an elective basis and $2,637.87 on an emergency basis, showing no significant discrepancies. The number of hospitalizations on an emergency basis was significantly higher than on an elective basis (62.64% and 37.36%, respectively). Conclusion: There was a concentration of figures in the Southeast region of the country, which led the way in terms of the total number of hospitalizations and deaths and accounted for almost half of the expenditure on the correction procedure. Equal public policies are needed throughout Brazil for early diagnosis and more elective treatment of AD.
