During 2015, he undertook a 6 month fellowship at the Aortic Centre, CHRU de Lille, France, under the supervision of Professor Stéphan Haulon. This centre is a world leader in the minimally invasive endovascular treatment of complex aortic aneurysmal disease using fenestrated and branched endografts. Whilst in Europe, Charles successfully sat the examinations for fellowship of the European Board of Vascular Surgery (E.B.V.S.), finishing the exam with honours, and receiving the award for the top-scoring candidate.
In 2015, Charles commenced a Master of Surgery (by publication) under the supervision of Professor Wendy Brown. The first part of his research is based on work undertaken whilst in France with Professor Haulon. This is looking at the suitability of inner-branched endografts for the treatment of aortic ach aneurysms in patients following ascending aortic replacement for acute type A dissection. This new technology is evolving as a treatment option for patients in this cohort who are at high-risk for conventional open surgical treatment. The second part of his research is based on work performed by the vascular unit at the Alfred Hospital, Melbourne. This is looking at the long-term follow up of patients following thoracic endovascular aortic repair (TEVAR) for traumatic aortic transection, with a particular focus on graft durability and aortic remodelling.
