Case report of a rare fistula caused by huge iliac aneurysm rupture into vena cava: Featured symptoms as liver function failure

Fistula caused by iliac aneurysm rupture into the inferior vena cava is a kind of extremely rare pathologic condition. In case of this, heart failure and lower extremity edema are the most often seeing symptoms. We report this patient has even rare symptoms of severe hepatic dysfunction. The hepatic function deteriorates from the beginning of the administration to the endovascular repair procedure. The bilateral iliac aneurysm and left iliac aneurysm-inferior vena cava fistula have been repaired by endovascular aortic repair (EVAR) and patients were discharged safely. Learn from this case and we treated before (1) hepatic function in this condition needs to be considering more and (2) EVAR is the mini-invasive and effective method to treat this rare situation.
