Dissection of the infrarenal aorta treated by stent graft placement

Abstract

Aortic dissection is primarily localized in the thoracic aorta. Dissection of the abdominal aorta is exceedingly rare, especially in the absence of a blunt abdominal trauma. Two cases of a primarily infrarenal aortic dissection were diagnosed by US, CT and angiography. The patients were treated by stent graft placement. The stent grafts were introduced via a femoral arteriotomy through the introducer sheath and were placed so that they occluded entry and reentry of aortic dissection. The stent graft placement caused total obliteration of a false channel of the dissection immediately after endoprosthesis deployment. The patients were followed-up by CT and angiography at 16 and 3 months after surgery without complication.
