Epidemiological insights into thoracic and lumbar sympathectomies in Brazil: a comparative analysis of open versus video-assisted procedures

Abstract

Purpose: To investigate the profile of hospital admissions for sympathectomies performed in the Brazilian Unified Health System (SUS), comparing open and video-assisted techniques. Methods: Data on sympathectomies were collected from the SUS Department of Informatics (DATASUS), recorded between 2014 and 2023. The data were tabulated, and descriptive statistics and correlation analyses were performed. Results: There was reduction in the number of admissions for all sympathectomies during the analyzed period. The use of video-assisted surgeries was higher than that of open surgeries for thoracic procedures, but lower for lumbar procedures. The costs of hospital admission for the procedures were similar, although the length of stay and mortality associated with open surgeries were higher, both in thoracic and lumbar sympathectomies. Conclusions: The collected data were not individualized, preventing follow-up. Additionally, the study did not account for procedures performed in the private healthcare system. Despite its limitations, this study provides an overview of sympathectomies in Brazil, indicating that, although open sympathectomies are potentially more disadvantageous, they are still widely performed, especially for lumbar procedures.
