Philip Colman has been a constant in the vascular surgical community in Newcastle since returning from training in Los Angeles and Oxford in 1991. His main area of interest has been the treatment of arterial disease, specifically endovascular therapies. He has a huge experience in endoluminal stent grafting for aortic aneurysms and performed the first successful endoluminal stent graft for ruptured abdominal aortic aneurysm in the region. He has also performed significant work in the treatment of complex abdominal and thoraco-abdominal aortic aneurysmal stent grafting and has taught other surgeons, both locally and internationally. He has performed major work in advanced endovascular treatment for peripheral arterial, cerebrovascular, renal and mesenteric arterial disease, treating patients with claudication, diabetic foot, TIAs and stroke. He has presented his experiences at national and international vascular meetings.

He established The Vascular Centre which is a centre of excellence in the provision of vascular ultrasound within Newcastle, the Hunter and Port Stephens areas. He is able to provide inpatient vascular ultrasound at Lingard Hospital. He offers outpatient clinical appointments at Hamilton, Nelson Bay, East Maitland, Toronto and Gateshead.

He is a conjoint senior lecturer at the University of Newcastle.
