Po-Jen Ko, MD, is a board certified vascular and endovascular surgeon, specializing in minimally invasive treatments for vascular diseases including aortic, peripheral arterial and venous diseases. Currently he is the chief of Vascular Surgery and the head of the vascular intervention team at Chang Gung Memorial Hospital.  He is also an active member of the Taiwan Society for Vascular Surgery and the International Society for Vascular Surgery.

Dr. Ko graduated from the National Taiwan University in 1992. He completed his fellowship in Thoracic and Cardiovascular Surgery at Chang Gung Memorial Hospital. Since then, Dr. Ko has focused his research on endovascular treatments for aortic pathology and peripheral vascular diseases. He has published over 100 papers in peer reviewed medical journals, and has also given numerous lectures at renown international symposiums.

Today, the Department of Thoracic and Cardiovascular Surgery uses minimally invasive techniques to treat a wide range of vascular related diseases which include: thoracic aneurysm/dissection, abdominal aneurysm, peripheral arterial occlusive disease, varicose vein and dialysis access related conditions. Every year, the vascular intervention team treats over 150 aortic cases, 400 lower limb arterial disease cases and 2000 dialysis access related cases.
