William T. Kuo, MD
Dr. William T. Kuo is Assistant Professor and Fellowship Director of Vascular and Interventional Radiology at the Stanford University School of Medicine. Dr. Kuo received a B.S. degree with honors from Duke University and he earned an M.D. degree from Wake Forest University School of Medicine with distinction in radiology, winning the Meschan award for radiology excellence. His surgical internship was accomplished at the Virginia Mason Hospital in Seattle, WA. He then trained in a combined interventional and diagnostic radiology residency program at the University of Rochester Medical Center where he served as Chief Resident and became one of the first in the nation to complete the Clinical Pathway in Vascular and Interventional Radiology. Following residency, Dr. Kuo received further endovascular training by completing his fellowship at Stanford University Medical Center.
Dr. Kuo's interests include catheter-directed thrombolysis for acute pulmonary embolism (PE), interventional therapy for deep vein thrombosis (DVT), and treatment of inferior vena cava (IVC) filter complications using advanced endovascular techniques including laser-assisted filter retrieval and IVC reconstruction. His clinical interests also include transarterial embolotherapy for the treatment of hepatic malignancies and endovascular treatment of renal and peripheral vascular diseases. At Stanford, he is conducting research to investigate the safety and efficacy of catheter-directed therapy for patients with life-threatening PE. His prior research has led to improvements in the treatment of venous thromboembolism and new therapies for permanently-embedded IVC filters. Dr. Kuo's work has been published in the Journal of Vascular and Interventional Radiology, Techniques in Vascular and Interventional Radiology and Chest. He has received numerous awards including being named among "America’s Top Radiologists" and "America's Top Physicians".
