Traumatic Nonanastomotic Pseudoaneurysm of Axillofemoral Bypass Graft A Case Report and Review of the Literature

Traumatic nonanastomtic disruption of an axillofemoral bypass graft (AFBG) is a relatively rare entity. However, we are reporting on an 82-year-old female who presented with a pulsating mass on her left side, which was noticed about 2 weeks after she fell on her side. The patient had undergone an ABFG about 15 years earlier for limb revascularization, and she had an occluded aortobifemoral bypass graft. A diagnosis of localized rupture with pseudoaneurysm (PSA) was confirmed with arterial duplex ultrasound and computed tomograph (CT) angiogram scans. A 7-cm PSA with partial disruption of the polytetrafluoroethylene (PTFE) graft at the level of the fifth thoracic vertebrae was noted. An initial work-up to eliminate the possibility of sepsis and localized mycotic seeding was negative. The patient was taken to the hybrid angiogram room, and a percutaneous cut down of the AFBG was performed with local dissection below the site of rupture. A limited angiogram showed a focal PSA of the AFBG. An intravascular ul...
