title: Open repair of inflammatory abdominal aortic aneurysm and aortocaval fistula using retrograde balloon occlusion.
abstract: OBJECTIVE
  The purpose of this report is to describe a novel endovascular technique used to minimize blood loss during the open repair of an aortocaval fistula (ACF) in the context of an inflammatory abdominal aortic aneurysm (AAA).
  
  
  METHODS
  We describe a patient who presented to our hospital with a symptomatic infrarenal AAA which was discovered intraoperatively to contain a large ACF. The patient underwent successful transperitoneal open repair of the AAA with balloon occlusion of the inferior vena cava to obtain distal control of the vessel.
  
  
  CONCLUSIONS
  Retrograde balloon occlusion of the inferior vena cava can be used to control hemorrhage during the open repair of an ACF, especially in the challenging setting of an inflammatory AAA.
