Renovascular hypertension
Renovascular Hypertension
Renovascular hypertension (pronunciation: ree-noh-vas-kyoo-lar hy-per-ten-shun) is a condition characterized by high blood pressure due to narrowing of the arteries that carry blood to the kidneys, often caused by atherosclerosis or fibromuscular dysplasia.
Etymology
The term "renovascular" is derived from the Latin "renes" meaning kidneys and "vascular" from the Latin "vasculum" meaning little vessel. "Hypertension" is from the Greek "hyper" meaning excessive and "tension" from the Latin "tensio" meaning stretching.
Symptoms
Symptoms of renovascular hypertension may include headache, nausea, and a sudden increase in blood pressure previously well controlled by medications. In some cases, it may lead to kidney failure.
Diagnosis
Diagnosis of renovascular hypertension often involves blood tests, urine tests, renal function test, and imaging tests like renal angiography, CT scan, or MRI.
Treatment
Treatment options for renovascular hypertension include medication to control blood pressure, lifestyle changes, and in some cases, procedures to improve blood flow to the kidneys such as angioplasty and stenting, or surgery.
