Role of late renal revascularization in functional renal salvage

Abstract

The duration that renal parenchyma will tolerate ischemia has continued to be debated. We have reported the cases of three patients who had undergone revascularization procedures with successful return of baseline renal function after prolonged renal artery occlusion of 14 days to 3 months. These cases highlight that aggressive revascularization can lead to successful renal salvage in selected patients. We examined the characteristics of these patients and those of others in the literature and reviewed the factors favoring recovery.
