Luka Pocivavsek, MD, PhD

Assistant Professor of Surgery

Luka Pocivavsek, MD, PhD, is a highly skilled vascular surgeon who specializes in a wide range of vascular conditions, including peripheral vascular, cerebrovascular disease and aortic disease.


As an active researcher, Dr. Pocivavsek advances vascular care by investigating innovative treatments and techniques for better outcomes and quality of life for his patients. His research focuses on improving treatment for patients with aortic dissections, a condition in which inner layers of the aorta tear and/or rip. Dr. Pocivavsek evaluates patients using specific aortic parameters to identify what treatment(s) would be most effective depending on each individual patient’s aortic anatomy. His research highlights the importance of examining both size and shape – as well as other features – of a dissected aorta before determining the right treatment. Appraising factors beyond size alone provides a more holistic picture of a damaged aorta, which not only indicates which patients will benefit from surgery, but also classifies patients that will have better long-term outcomes with medical management alone.


His research has been published in several peer-reviewed journals, such as Science, Nature Physics, Journal of Vascular Surgery, Biophysical Journal, Soft Matter, Biomaterials and Annals of Vascular Surgery. Dr. Pocivavsek also presents his findings at conferences and meetings both domestically and internationally.


In addition to his clinical practice, Dr. Pocivavsek is also the co-founder of ArugaTechnologies, a medical device company that designs synthetic vascular grafts using new surface technology inspired by nature.

Why does this provider not have a star rating?

Our goal is to provide our patients and visitors with correct and useful information. We only post provider satisfaction information from clinic surveys when they are returned from patients.

This provider has not had surveys returned that meet the necessary sample size

About Our Star Ratings and Comments:

Randomly selected patients are sent patient satisfaction surveys after their visits. We get thousands of survey responses each year. The responses are used to improve patient experience and recognize staff members for the care they provide. Patient survey responses are also used to make star ratings for each provider.

For the star ratings and comments, all feedback on the provider web page is posted as it was given from patients. Comments that do not apply, risk patient privacy, or are not appropriate are not posted. Star ratings and comments come from a number of survey questions. A star rating is not given if a provider only has a small number of survey responses.
