Use of the hepatic arterial circulation for renal revascularisation.

Renal artery stenosis is increasingly being diagnosed as a cause of hypertension and renal impairment. Surgical intervention can restore function and improve hypertension in selected cases. Over a 42 month period, 12 patients with atherosclerotic renovascular disease underwent surgical revascularisation using the hepatic arterial circulation. All had disease of both renal arteries and 11 had some degree of renal impairment, with five requiring dialysis before operation. There were two deaths within 30 days of operation, eight patients had improved renal function after operation and three of the patients previously on dialysis became dialysis free. The hepatorenal method of renal revascularisation is described and its advantages discussed.
