Biography

About Geoffrey Ouma, DO

Geoffrey Ouma, DO, MS, FSVM, RPVI, is a vascular disease specialist in the Tomsich Family Department of Cardiovascular Medicine, Sydell and Arnold Miller Family Heart, Vascular and Thoracic Institute. He sees patients at Cleveland Clinic main campus.

Specialty Interests: Peripheral artery disease (PAD), especially evaluation of limb pain and medical management of claudication; cardiovascular/atherosclerosis risk factor modification in PAD and carotid artery disease/stroke; evaluation and medical management of patients undergoing non-cardiac vascular surgery; limb swelling and chronic venous insufficiency, lipedema, lymphedema, varicose veins, arteriovenous/capillary venous malformations; endovascular therapy for varicose veins and chronic venous insufficiency; complex venous thromboembolism, pulmonary embolism, deep vein thrombosis (DVT), high-risk thrombophilia, complex atherothromboembolism, post-thrombotic syndrome, May-Thurner syndrome, thoracic outlet syndrome, DVT in pregnancy; coagulopathies; management of inferior vena cava filters and noninvasive vascular disease testing; lower extremity wounds

Experience: The Section of Vascular Medicine in Cleveland Clinic’s Tomsich Family Department of Cardiovascular Medicine offers comprehensive care for diseases of the vascular and lymphatic systems, including hyper-coagulable disorders. The section is home to one of the most active vascular laboratories in the country, with more than 2,200 clinical studies performed per month.

Dr. Ouma has more than 10 years’ experience in diagnosing and managing the full range of blood vessel and lymphatic disorders and has treated more than 1,500 patients with venous leg ulcers. His expertise also includes the diagnosis and management of less common vascular disorders such as thromboangitis obliterans (TAO), fibromuscular dysplasia (FMD), the vasculitides, vasospastic disorders, blue/cold fingers and toes and arterial aneurysm. He is board certified in internal medicine, vascular medicine and wound healing, holds certification in hyperbaric oxygen therapy and is a Registered Physician in Vascular Interpretation (RPVI). Dr. Ouma is a Fellow of the Society for Vascular Medicine.

Success Rates: Success rates for specific vascular procedures at Cleveland Clinic are available at http://my.clevelandclinic.org/heart/about-heart-vascular-institute/treatment-outcomes.aspx.

Education: Dr. Ouma earned his medical degree from Lake Erie College of Osteopathic Medicine, Erie Pa. He completed his internal medicine residency at the University of Wisconsin, Milwaukee Clinical Campus/Aurora-Sinai Medical Center, Milwaukee, Wis., followed by a fellowship in vascular medicine at Hospital of the University of Pennsylvania, Philadelphia. During his fellowship, Dr. Ouma earned a master’s degree in translational research from Perelman School of Medicine at the University of Pennsylvania. In 2014 and ‘15 he completed specialized trainings in hyperbaric medicine and wound care medicine.

In 2018 Dr. Ouma participated in a medical mission to Kenya with the organization Hands International. Prior to joining the Cleveland Clinic medical staff in 2020, he was on the staff of Thomas Jefferson University Hospital in Philadelphia.

Publications and Speaking: Dr. Ouma has coauthored papers in peer-reviewed medical journals on peripheral artery disease and limb ischemia and presented abstracts on vascular medicine topics at medical meetings. He served as an editor and contributed a chapter to Atlas of Vascular Medicine: A Case-Based Approach to Current Management (2011) and coauthored a chapter in a leading vascular surgery textbook on hypertension as a risk factor for atherosclerosis.

About Dr. Ouma: “I enjoy the field of vascular medicine because patients often present with uncommon vascular diseases that other physicians have not been able to diagnose. It is always gratifying to help patients finally get answers to their medical problems. I immediately witness how I have been part of relieving their worries and anxiety. Although the majority of these vascular ailments are benign, they are worrisome and annoying and, therefore, difficult for a patient to ignore.

Leisure Activities: In his leisure time, Dr. Ouma enjoys playing the guitar, listening to music, cooking Kenyan food, travelling with his family and playing pick-up soccer games.

Industry Relationships

Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

As of 4/23/2023, Dr. Ouma has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities.
