Dr. Marcelo Guimarães started his six years of medical training at the School of Medicine at the Federal University of Rio Grande Sul in Porto Alegre, Brazil. During his time in medical school he volunteered at the Hospital Santa Casa, the Hospital de Clinicas and the Hospital Santa Casa, all located in Porto Alegre. At these hospitals he spent time in intensive care, gastroenterology, internal medicine, general surgery, trauma surgery and radiology. He also taught human anatomy, clinical biochemistry, clinical pathology and clinical epidemiology. In 1994, during his third year of medical school, Dr. Guimarães traveled to Oxford Medical University (John Radcliffe Hospital) in England for two months where he had his first exposure to minimally invasive procedures performed under image guidance. Upon his return to Brazil after finishing medical school, he had post-graduate training that included a general surgery residency, a general and interventional radiology residency (Hospital de Clínicas in Porto Alegre and in Recife, Brazil, respectively) and a two year fellowship at the interventional radiology division at the Medical University of South Carolina in Charleston, South Carolina.After 12 years of medical education in Brazil and in United States, Dr. Guimarães developed successful academic (Hospital de Clinicas) and private (Hospital Moinhos de Vento) practices in Porto Alegre, Brazil where more than 2,000 different interventional radiology procedures were performed from 2005 to 2007. The lack of time to work simultaneously in clinical practice and research made the invitation to return to work at MUSC very attractive.Dr. Guimarães began working as an assistant professor at the division of vascular and interventional radiology at the Medical University of South Carolina in January 2008. Since then, he has worked on research projects and has been invited to present lectures in several relevant national and international meetings in his field of work. He is deeply interested in peripheral vascular disease and in oncology procedures. Dr. Guimarães’ strongest interests are in the development of new interventional radiology techniques and devices that can increase procedure safety and in providing superior care to his patients.
