Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

The aorta is our largest artery, supplying blood to our organs and limbs. The aorta runs from the heart up towards the head (ascending aorta), curves towards the back and arches (aortic arch) to turn downward, running along the spine (descending aorta).
Aortic aneurysm is the most common aortic disorder. This condition causes a thinning of the aortic wall, increasing the risk of a life-threatening tear or rupture. This can be avoided by replacing the affected segment of the aorta. The timing and type of treatment depends on the location and size of the aneurysm.
Aneurysms of the ascending aorta and the aortic arch require replacement of the affected segment with artificial vascular prostheses. The replacement can be performed in a minimally invasive manner through a partial sternotomy.
Aneurysms of the descending aorta can be treated with conventional surgery or percutaneously with a stent.
