Tilo Kölbel (University Heart Center Hamburg, Germany) outlines the main considerations when undertaking endovascular interventions in the ascending aorta and aortic arch. While discussing the surprisingly good results seen in this group of patients (who are typically older and frailer than those undergoing surgical intervention), Kölbel particularly draws attention to the concept of air embolization and how it might go a long way towards explaining the significant stroke risk that these carry. He was interviewed at CIRSE 2018 in Lisbon, Portugal.
