Professor Santi Trimarchi is Professor of Vascular Surgery at the University of Milan. His clinical interests include both open surgery and endovascular treatment of thoracic, thoracoabdominal and abdominal aortic diseases, primarily dissections and aneurysms. Prof. Trimarchi completed a residency in vascular surgery and a fellowship in cardiac and thoracic vascular surgery at the University of Milan, Italy. He was research scientist for thoracic aortic diseases at the University of Michigan (2006), and at Yale University (2008). In 2008, he completed a Master in Endovascular Techniques (MET) at the University of Milan-Bicocca, Italy, and in 2012 he earned a PhD from Utrecht University, the Netherlands, focusing on insights into acute aortic dissection. Prof Trimarchi is co-PI of the International Registry of Acute Aortic Dissection (IRAD), co-director of the IRAD Surgical/Endovascular program, co-PI of the Gore GREAT registry, and co-investigator in other international registries, including the European Registry of EVAR complications (EuREC) and the International Aortic Arch Surgery Study Group (IAASSG). Prof Trimarchi is a committee member for several ESVS guidelines: Guidelines on Thoracic Aortic Diseases, 2017; Guidelines on Abdominal Aortic Diseases, 2020; Clinical Practice Guidelines on the Management of Chronic Venous Disease of the Lower Limbs 2022, and Clinical Practice Guidelines on the Management of Abdominal Aorto-Iliac Artery Aneurysms 2024. He recently chaired the European Society for Vascular Surgery (ESVS) 2025 Clinical Practice Consensus Statement on Ascending Thoracic Endovascular Aortic Repair, which he will present at our Annual Scientific meeting in Adelaide.
