Matthew P. Sweet, M.D., M.S., is a board-certified vascular surgeon, Section Chief of Vascular Surgery at UW Medical Center - Montlake, and an Associate Professor of Surgery at UW School of Medicine.

Dr. Sweet is trained in the use of both open and endovascular surgical techniques to manage vascular disease.  He strives to develop the optimal treatment plan for each patient, utilizing both surgical techniques as needed. Dr. Sweet has a particular interest in complex aortic aneurysms, including thoraco-abdominal and arch aneurysms. Operations performed to treat these aneurysms are high risk, and helping patients navigate the decision making about what to do for these aneurysms is something he is very focused on. He has also worked to help build a multi-disciplinary team for the care of patients with these complex aneurysms. This team-based approach expands the tools the team has available to treat patients and, Dr. Sweet believes, improves the care they receive.

Dr. Sweet’s research interests include the morphology and natural history of thoraco-abdominal aneurysms, as well as in improving treatment decision making for these high risk aortic conditions. Dr. Sweet runs a Physician Sponsored Investigational Device Exemption study utilizing custom made branched and fenestrated stent grafts for the endovascular treatment of thoraco-abdominal aneurysms. He is also the site lead investigator for industry sponsored clinical trials of branched endografts designed for treatment of both thoraco-abdominal and aortic arch aneurysms.
