Objective: To outline the epidemiological profile of patients in the Hemodynamics in a referral hospital in Curitiba, Paraná, Brazil. Interventional neuroradiology is crucial in the management of cerebrovascular diseases, offering minimally invasive methods to diagnose and treat conditions such as aneurysms, arteriovenous malformations, carotid atherosclerotic disease, and other conditions. However, there is a lack of studies on the epidemiological profile of patients who undergo these procedures. Methodology: Cross-sectional, retrospective study based on secondary data of neurovascular procedures performed between 2008 and 2024 at the Hemodynamics of INC Hospital. The following variables were analyzed: age, gender, health insurance, and type of procedure, using descriptive statistics in Excel®. Results: The sample included 4607 patients, with a mean age of 52 years (± 16.21). The majority (55.6%, n = 2559) were in the 30-59 age group, followed by patients over 60 years of age (35%, n = 1613). Women (61.88%, n = 2851)) predominated over men (38.12%, n = 1756). Regarding the paying source, 92.73% (n = 4272) of the patients had health insurance and 7.27% (n = 335) private resources. Cerebral arteriography was the most frequent procedure (72.43%, n = 3337), followed by aneurysm treatment (10.29%, n = 474) and carotid angioplasty (8.14%, n = 375). Discussion: The results show that the procedures are mostly performed in adults, although the elderly represent a significant portion. The prevalence of cerebral arteriography highlights its importance in clinical diagnosis. These findings are fundamental for understanding the epidemiological profile, contributing to the strategic planning and optimization of hospital resources aimed at the treatment of cerebrovascular diseases.
