Galveston County Daily News, Nov. 22, 2008 Dr. Lois Killewich of UTMB and her husband, Jim Gregory, came upon a motorcycle accident where a man had severed a leg. Killewich noticed that a tourniquet was not working after the victim was administered fluids. Killewich pulled down the popliteal artery and held it until she was able to tie it off. "I've dealt with incidents of that nature hundreds of times in the operating room," she said. "But that is the most serious incident I've dealt with outside the hospital in my whole career, and I've been around for 25 years."
