Todd Rasmussen  Todd E. Rasmussen, MD, FACS, Colonel, USAF MC, is a Professor of Surgery and Associate Dean or Research at the Uniformed Services University of the Health Sciences and an attending vascular surgeon at the Walter Reed National Military Medical Center. Colonel Rasmussen completed his medical degree at Mayo Medical School, surgical training at Wilford Hall Medical Center on Lackland Air Force Base, and vascular specialty training back at Mayo Clinic. Colonel Rasmussen was assigned to Andrews Air Force Base just before 9.11.2001 and soon after began caring for the injured returning rom Aghanistan at Walter Reed Army Medical Center. He began a series of deployments to the Air Force Theater Hospital on Balad Air Base, Iraq, and Bagram Air Base and the Afghan National Army Hospital in Kabul, Afghanistan. During this time he initiated a research and innovation program aimed at developing a better understanding of vascular injury, hemorrhage control and shock as well as new approaches to managing these conditions. Colonel Rasmussen has led training missions in Morocco, Pakistan, and Russia, and his research efforts have resulted in hundreds of publications, including two textbooks, the "Handbook of Patient Care in Vascular Disease" and the "3rd edition of Rich's Vascular Trauma". He authored Vascular Injury Rates in the Wars in Iraq and Afghanistan in which he wrote that the frequency of vascular injury on the battlefield has increased by a factor of 5 between Vietnam and the current wars. Rasmussen was also one of the investigators in the Military Application of Tranexamic Acid in Trauma Resuscitation Study (MATTERS) which was a collaboration with British researchers on the use of a drug called tranexamic acid (TXA) in patients with severe bleeding. The study indicated that patients treated with TXA survived twice as often as those who did not receive the drug. Colonel Rasmussen is a co-inventor of REBOA (resuscitative endovascular balloon occlusion of the aorta), which is a minimally invasive approach used to sustain blood pressure and control bleeding in severely injured and shocked patients. The ER-REBOA catheter of which he is a co-inventor has been used thousands of times in the U.S. and around the world and was featured in a 2017 New York Times article by Denise Grady. In 2019, Dr. Rasmussen led a team of military surgeons at Walter Reed National Military Medical Center as the first in the Military Health System (MHS) to implant the Human Acellular Vessel, or HAV, into a patient who was in danger of losing his leg from vascular disease.
