Biography

Dr. Malas is a vasular surgeon specializing in minimally invasive treatment of vascular conditions. His clinical and research interests focus on minimally invasive endovascular repair of abdominal, thoracic and peripheral aneurysms, aortic dissection, angioplasty and stenting of: the carotid artery with cerebral protection to prevent stroke; the renal artery to prevent renal failure and treat intractable hypertension; the subclavian artery to treat steal syndrome; the lower extremity arteries for limb salvage and to treat intermittent claudication. Dr. Malas provides comprehensive assessment of venous disease, including varicose veins and chronic venous insufficiency.

    Professional Activities

    Since he joined the Johns Hopkins University, Department of Surgery, Dr. Mahmoud Malas was able to bring more than 10 national vascular and endovascular clinical trials to the Department of Surgery. There are now more than 100 research participants in these clinical trials. Dr. Malas is the principal investigator of all these trials at Johns Hopkins. He received the NIH KL-2 Clinical Research Scholar Awards in 2008 and then two additional supplement awards. The total direct cost of these trials plus the NIH grant funding is approximately one million dollars. Dr. Malas completed my degree in Master Health Science at the Johns Hopkins Bloomberg School of Public Health under the K award. The experience gained from running these trials, the education received through his masters and the funding secured helped establish the Johns Hopkins Bayview Clinical Research Center for Vascular and Endovascular surgery. Johns Hopkins Bayview is part of the most advanced national and international clinical trials in open and endovascular treatment of aneurysm, carotid and peripheral arterial disease.
