Restenosis of Aorto-renal Venous Grafts: Report of Two Patients Treated by Endovascular Stenting.

Introduction: Renal venous graft restenosis is an uncommon event usually associated with significant clinical impact. Its treatment by endovascular stenting is seldom reported in the literature.

Report: Two cases of successful stenting for restenosis in aorto-renal venous grafts are described, detailing the technique and in one case reporting for the first time the use of a covered stent in this condition.

Discussion: Technical success may be achieved with proper material selection for the patient's anatomy and with dilation at relatively high pressures. The use of a covered stent may provide extra safety when treating vein grafts.
