Biographical Sketch

VAscular Surgeon Sydney, Dr. Walid MohabbatWalid Mohabbat is a specialty trained vascular surgeon with subspecialty training in endovascular and aortic surgery. He specialises in open and endovascular stentgraft repairs for abdominal aortic aneurysms (AAA) and thoracic aortic aneurysms (TAA) and aortic dissections, complex endografting (fenestrated and branched endograft repairs) for juxtarenal, suprarenal and thoracoabdominal aortic aneurysms and dissections, carotid endarterectomy (CEA) and carotid artery stenting (CAS), lower extremity endovascular treatments including angioplasty, stenting, laser atherectomy. He also specialises in endovenous therapies for varicose veins including percutaneous laser vein ablation.

Dr Mohabbat grew up on the North Shore and received his medical degree from the University of Sydney. He undertook general surgical training at the RPA and POW hospitals. He then completed a three year fellowship in vascular surgery including training years at RNSH, Sydney and PA, Brisbane. Dr Mohabbat received his FRACS (Vascular) in 2006.

Under the mentorship of Roy Greenberg, MD, a world renowned vascular surgeon, Dr Mohabbat then joined the Department of Vascular Surgery at the Cleveland Clinic Main Campus in Cleveland, Ohio USA. There he obtained his Ohio State Board Medical License and completed fellowships in the fields of vascular research, aortic surgery and endovascular surgery in the United States' consistently number one ranked heart and vascular institute. His main clinical focus was on the endovascular management of complex aortic disease with fenestrated and branched endografts. After two years in the USA, Dr Mohabbat then returned to commence vascular surgical practice.
