Dr. Kougias has a strong interest in clinical and health services research and has multiple active protocols supported by peer reviewed and industry funding. He is actively investigating the effect of carotid endarterectomy and stenting on cognitive function and associated intracerebral hemodynamics. He is also studying the relative cost of endovascular and open interventions in the treatment of patients with lower extremity vascular disease and the influence of transfusion policy on outcomes after operative intervention in high risk patients. In addition, he is developing a model to predict the duration of a variety of surgical interventions with the ultimate goal to implement an operating room – wide predictive algorithm that will streamline operating room patient flow, decrease downtime, and improve efficiency, and staff and patient satisfaction.
His research interests also include endovascular treatment of aortic aneurysms, venous disease, and endovascular treatment of lower extremity occlusive disease.
Dr. Kougias has contributed more than 40 articles to scholarly and professional journals, such as Surgical Forum, Journal of Surgical Research, Atherosclerosis, Vascular Surgery, Journal of Vascular Interventional Radiology, Journal of Endovascular Therapy, and Journal of Vascular Surgery. He has authored or co-authored more than 10 book chapters.
