Revascularization of the Completely Occluded Renal Artery

Less well documented is the therapeutic strategy for patients that have complete thrombosis of the renal artery. This uncertainty is attributable to the fact that most patients who undergo complete thrombosis of the renal artery develop nonfunctional diminutive kidneys not amenable to reconstruction.2-4 However, Sheil and colleagueS2-4 demonstrated histologically that in some cases of complete renal artery occlusion, there was enough collateral circulation to keep the affected kidney viable although physiologically nonfunctioning. Revascularization of the completely occluded renal artery in these patients led to the reappearance of excretory function in the involved kidney. We report a case of acute occlusion of a chronically obstructed renal artery associated with severe hypertension. This patient was successfully treated by autogenous saphenous vein renal artery bypass.
