Two weeks later, Mr R underwent placement of an endovascular aneurysm repair (EVAR) stent graft. The vascular closure device maldeployed on insertion but was fixed and correctly positioned, according to the operative note. Six months later, Mr R came back to his primary care physician reporting that his left leg was completely numb. The leg was found to be pulseless and cold. He had experienced a total occlusion of his EVAR graft. He underwent emergency thrombectomy and axillary-femoral bypass to his leg performed by a vascular surgeon. Despite this, Mr R's creatine kinase level began to increase, and his leg was noted to be taut. Three more operations followed, over the course of 2 months, to relieve compartment syndrome and later for wound debridement and dehiscence. Despite these efforts, Mr R was left with a persistent foot drop, requiring use of a walker. He underwent a month of rehabilitation for deconditioning, an experience he calls, “the low point of my life.” Today, Mr R, by his own account, is a shell of his former self. He is gaunt, like “Dick Cheney,” he jokes. He requires a walker. Because of the extent of his thrombosis, his vascular surgeon has recommended lifelong warfarin sodium therapy (Coumadin; Bristol-Myers Squibb). “Not the best idea for someone prone to falling,” Mr R tells me.
