After completing his MD Radiology in India, Dr. A. Chavan migrated to Germany and commenced his advanced training in Radiology at the Hannover Medical School in 1991, where he was put in charge of Interventional Radiology in 1993. He passed his German Board Examination for Radiology in 1996, after which he was appointed Consultant in Radiology at the Hannover Medical School. He was awarded his Associate Professorship in 2001 (for his animal experimental work on suprarenal fixation of aortic stent-grafts) and Full Professorship of Radiology in 2008. Since January 2004, Prof. Chavan assumed responsibility as Director of the Institute of Diagnostic and Interventional Radiology at the Klinikum Oldenburg in Germany, which is part of the European Medical School Oldenburg-Groningen.
Prof Chavan was largely instrumental in establishing and developing the speciality of Interventional Radiology at the Hannover Medical School as well as at the Klinikum Oldenburg, European Medical School.
Prof. Chavan has done extensive clinical and research work in the fields of chemoembolization of hepatic tumors, renal as well as peripheral angioplasty and stenting, interventional treatment of vascular malformations as well as the minimal invasive therapy of aortic aneurysms and aortic dissections. His role in the treatment of hepatic involvement in HHT (Hereditary Haemorrhagic Telangiectasia) patients as well in establishing the “Frozen Elephant Trunk” technique for the treatment of multi-segment thoracic aortic pathology is worthy of special mention. Together with Prof. A. Haverich (Head, Dept. of Cardiothoracic Surgery, Hannover Medical School), he developed a hybrid endograft (Chavan-Haverich endograft) for intra-operative implantation in patients with extensive thoracic aortic aneurysms and dissections, which reduces the two step-surgery necessary in such patients to a single-step procedure.
Prof. Chavan has been instrumental in establishing stent grafting for aortic aneurysms and aortic dissections in various institutions in Germany, Austria, Israel, India and Singapore.
