A 71-year-old woman, who had undergone axillo–bifemoral bypass using externally supported bifurcated Dacron graft for Leriche syndrome in 2006, and thrombectomy for acute thrombotic occlusion of the graft in 2012, experienced deterioration of intermittent claudication in the left leg in 2013. Enhanced CT showed a pseudoaneurysm and stenosis of the graft at the level of the third lumbar vertebra. She underwent surgery with a diagnosis of non-anastomotic pseudoaneurysm due to graft disruption. After incising the pseudoaneurysm, the disrupted portion of the graft was resected and partially replaced with a new vascular prosthesis. On macroscopic examination, the disruptions were seen along the broken externally supported coils. As disruption sites corresponded to her waistline, repeated external mechanical force such as bending and stretching of the waist could be considered as a cause of the graft disruption. Careful long-term follow-up is needed.
