Effective treatments for renal artery stenosis include medications that control high blood pressure or lower cholesterol, angioplasty interventions, and surgery to remove the blocked part or nonfunctioning kidney, according to WebMD. Such treatments have shortcomings, however. Medication may cause headaches, while angioplasty complications may further damage the kidney.
Renal artery stenosis is a condition where the kidney's arteries narrow due to a buildup of plaque or, in rare cases, fibromuscular dysplasia, explains WebMD. The condition causes less blood to reach the kidneys and results in high and hard-to-control blood pressure. Females and those suffering from hypertension, diabetes or chronic kidney disease are most at risk for renal artery stenosis.
