Mr Mahmood was born and brought up in Small Heath, Birmingham and went to school at King Edward VI Aston Grammar School. He graduated from the University of Birmingham Medical School in 1995 and went on to train in Vascular Surgery in the West Midlands. In 2006, he was awarded the degree of MD from the University of Birmingham for his research on reducing inflammatory response and organ dysfunction during aortic surgery. During his research fellowship he also co-ordinated the national EVAR trials as well as publishing widely on lower limb bypass techniques. After completing higher surgical training in the West Midlands Deanery, he undertook an Endovascular Fellowship at the Freeman Hospital in Newcastle-upon-Tyne specialising in endovascular aortic aneurysm repair (EVAR) and radiofrequency ablation for venous disease.
Mr Mahmood was appointed as Consultant Vascular and Endovascular Surgeon at the University Hospital Coventry & Warwickshire in 2009 and has since developed complex endovascular surgery including fenestrated EVAR and EVAR for ruptured aneurysms, receiving clinical excellence awards for this. He offers the full range of treatments for vascular disease but his main focus is minimal invasive surgery.
