Hepatorenal bypass using autogenous, free internal iliac artery graft: An attractive alternative to revascularize the right kidney in Takayasu′s disease

Abstract

Nonspecific aortoarteritis or Takayasu's disease (TD) is a chronic pan endarteritis of unknown origin involving the aorta and its major branches affecting young adults especially women. The disease is more common in eastern Asian countries. Hypertension in these patients generally reflects as renal artery stenosis, which is seen in 28–75% of patients. Surgical revascularization is occasionally needed in patients with failed medical management or endovascular interventions. We report two cases of Takayasu's arteritis in young women where renal revascularization was done using free internal iliac artery hepatorenal bypass graft with excellent control of hypertension in the postoperative period.
