Renal artery occlusion; Stenosis - renal artery; Occlusion - renal artery; Fibromuscular dysplasia (FMD) Treatment:
The treatment varies depending on the extent and severity of the symptoms. If the stenosis results in failure of a kidney, the second kidney may take over filtering and urine production for the body. Surgical repair of the stenosed area may be possible. Text Continues Below
A balloon angioplasty (a radiographic procedure during which a balloon-tipped catheter is threaded through the artery) or a stent placement across the stenosis may be an alternative to surgery to open the stenosed area.
Antihypertensive medications may be needed to control high blood pressure. Expectations (prognosis):
Renal artery stenosis may cause eventual failure of the kidney if it progressively blocks the artery. This may result in chronic renal failure if there is only one functional kidney or if both renal arteries are affected. Renal hypertension caused by renal artery stenosis may be difficult to treat. Surgical or balloon catheter repair often successfully opens the stenosed area. However, stenosis may recur. Complications:
Calling your health care provider:
If your history indicates a high risk for renal artery stenosis, make an appointment to see your health care provider. However, decreased urine volume may be an emergency symptom indicating renal failure.
