A Case of Surgical Revascularization in a Patient with Uncontrolled Renovascular Hypertension and Renal Dysfunction after Repeated Percutaneous Transluminal Renal Angioplasty (PTRA) for More Than 10 Years.

Percutaneous transluminal renal angioplasty (PTRA) is a treatment for renovascular hypertension due to renal artery stenosis. However, postoperative complications in stent re-stenosis/occlusion may occur frequently. A 60-year-old male patient presented to our hospital with uncontrolled hypertension and a deterioration of renal function. He had undergone an initial renal stenting 10 years earlier, followed by repeat PTRAs during follow-up for in-stent restenosis. The left renal stent was found to be completely occluded, while the right renal stent was found to be 75% stenosed. We performed an aorto-renal artery bypass. The bypass was patent without stenosis and the renovascular hypertension was recovered.
