Mr Obi Agu

Consultant General Vascular and Endovascular Surgeon


Specialises in

I have been a consultant general vascular and endovascular surgeon for over 10 years.

I specialise in general vascular surgery with an interest in varicose veins, surgical access, open and endovascular repair of aortic aneurysms, angioplasty and bypass surgery for blocked and narrowed arteries, carotid endarterectomy for stroke prevention, vascular malformations, DVT and leg swelling, open hernia repairs, lumpectomies and vascular surgical support for major operations all over the body especially involving large blood vessels.

I also specialise in providing surgical access to the spine from the front, operating jointly with spinal surgeons.

My research-based higher degree was on management of varicose veins for which I received the European Venous Forum first prize. I am a national trainer for endovascular treatment of aortic aneurysms and dissection.

I have an active clinical and research interest in computational modelling of aortic disease. I am also a Reviewer for European guidelines for managing arterial diseases including leg claudication, diabetic and leg ulcers, carotid disease, renal and mesenteric artery stenosis (narrowing).

I am Chair of NHS London Vascular Advisory Group. I am also proud to be an Honorary Senior Lecturer in Surgery at University College London Hospital.
