Christopher W. Brennig, M.D.

Certified by:
American Board of Vascular Surgery
American Board of General Surgery
Founder & Director of the Austin Vein Institute

Dr. Brennig is the founder and director of The Austin Vein Institute. He is currently the only surgeon certified by The American Board of Vascular Surgery dedicated exclusively to the evaluation, diagnosis, and treatment of vein conditions which includes varicose veins and spider veins. He is also an expert in the management of other vein conditions including blood clots, venous leg swelling and associated skin conditions (ulcers, hemorrhage and dermatitis).

Dr. Brennig graduated from the University of Texas in Austin, earning a Bachelor of Arts degree in Biological Sciences. He continued his education at the University of Texas Medical School in Houston where he obtained his medical degree. After his General Surgery internship at the Baylor College of Medicine in Houston, he completed his general surgery residency and served as chief surgery resident at Baylor University Medical Center in Dallas.

During his five-year general surgery residency, Dr. Brennig developed a keen interest in the field of vascular diseases, vascular surgery and the latest minimally invasive catheter based therapies available to treat those affected. This led him to Boston and the Tufts University Medical Center two-year Vascular Surgery Fellowship, where he trained with an emphasis on complex minimally invasive vascular therapies including treatment of complex venous disorders.

After his seven years of specialty training in Houston, Dallas, and Boston, Dr. Brennig was recruited to Austin by St. David’s Healthcare System, to provide state-of-the-art vascular care for central Texas patients suffering with critical life and limb-threatening vascular conditions. He developed a very busy and successful vascular and endovascular surgery practice treating some of the most severe and complex arterial and venous vascular conditions. He performed St. David North Austin Medical center’s first thoracic aortic endograft repair for a patient suffering with a dissecting thoracic aortic aneurysm. He also performed the hospital’s first endovascular clot lysis-recanalization, angioplasty and stent treatment for complex DVT / May Thurner Syndrome with great success. There he organized a vascular surgical team that successfully treated many Texas residents with life-threatening abdominal aortic aneurysms, limb threatening arterial occlusive diseases, and complex arterial and venous blood clots.

As Dr. Brennig developed his hospital-based vascular and endovascular surgery practice, more referrals from local physicians began pouring in as physicians sought the most current and best treatments for their patients with venous problems. The result was a busier office-based vein treatment practice. It became apparent to Dr. Brennig that there was a significant need for more expert and dedicated care in the treatment of vein disorders for the residents of Austin and central Texas. Dr. Brennig then decided to dedicate his entire vascular practice and resources exclusively to treating patients with vein disorders. Now using the latest technologies and advancements, patients are safely and best treated in the office setting here at the Austin Vein Institute.

Dr. Brennig’s breadth of experience and success in treating the most complex vascular conditions has allowed him to develop a uniquely qualified approach to help his patients with vein problems.

Dr. Brennig has presented multiple research papers, published articles, and continues to train other physicians and health care providers in emerging vein therapies. He is the founder of The Austin Vascular Institute and its affiliate, The Austin Vein Institute.
