Interventional Radiology


Interventional and Vascular Radiology, in many cases, will provide patients with a minimally invasive alternative to surgery, giving them no more than a small puncture site post procedure and faster recovery times. Dr. J. Dana Dunleavy, leads Windsong’s Interventional and Vascular Radiology team, performing a breadth of image-guided procedures at Windsong Radiology Group’s Williamsville location. Dr. Dunleavy completed his Diagnostic Radiology Residency at the Johns Hopkins Hospital as well as his Fellowship in Vascular and Interventional and Vascular Radiology, serving as Chief Fellow. He is a board certified radiologist and specializes in venous insufficiency, interventional oncology, and pain management. He is a frequently requested speaker on varicose vein evaluation and treatment.
