Renovascular Hypertension Program

Renovascular hypertension is high blood pressure due to narrowing of the arteries that carry blood to the kidneys (called renal artery stenosis). When the kidneys are getting less blood, they respond by sending signals to increase the body’s blood pressure to get more blood flow to the kidney. It is a serious and potentially life-threatening condition that requires coordinated, personalized and expert care.

At Seattle Children’s Renovascular Hypertension Program, we treat the whole patient, not just their illness. Our team of nephrologists, interventional radiologists, surgeons and nurses works together collaboratively to provide expert care in a compassionate, healing environment.

Why Choose Seattle Children’s Renovascular Hypertension Program?

Renovascular hypertension is a rare and serious condition that requires the expertise and care of a team of pediatric specialists who are highly skilled in treating vascular problems affecting the kidneys. Our team works with you to provide complete care for your child and family. We tailor our expert care to meet your child’s unique health needs.

Only a handful of hospitals in the nation have the expertise to successfully treat renovascular hypertension.

Conditions We Treat

Renovascular hypertension may be associated with different medical conditions. At Seattle Children’s Renovascular Hypertension Program, we treat children with the following conditions that may lead to renovascular hypertension:

  • Alagille syndrome

    Alagille syndrome is a genetic disorder that causes reduced bile flow because there are too few bile ducts inside the liver. Some individuals may develop renal artery disease with narrowing of vessels and elevation of the blood pressure.

  • Fibromuscular dysplasia

    Fibromuscular dysplasia is a condition that causes narrowing of the medium-sized arteries in the body. Reduced blood flow from narrowed arteries to the organs they supply (like the kidneys) can affect their function.

  • Midaortic syndrome

    Also known as middle aortic syndrome, midaortic syndrome is a narrowing of the middle parts of the aorta where it runs through the chest and abdomen area. The aorta is the main artery off the heart that delivers oxygen-rich blood throughout the body. Blood flow to the kidneys is impaired due to the narrowing of the aorta or the renal arteries.

  • Takayasu arteritis

    Takayasu arteritis is a rare disorder that causes inflammation of the blood vessels (vasculitis). The inflammation damages the large artery (called the aorta) that carries blood from your heart to the rest of your body and its main branches.

  • Tuberous sclerosis

    Tuberous sclerosis is a rare genetic disease that causes non-cancerous (benign) tumors to grow in many parts of the body. Tumors may grow in the renal artery, blocking blood flow to kidneys.

  • Williams syndrome

    Williams syndrome is a genetic condition that is present at birth and is marked by several medical complications, including problems with kidney structure and/or function. Narrowing of the aorta and/or renal arteries may develop during childhood.

  • Nutritional evaluation and counseling

    Our registered dietitians can help you, your child and your family learn about foods to help control blood pressure meet your child’s nutritional goals.

  • Ambulatory blood pressure monitoring (ABPM)

    An ambulatory blood pressure monitor is a small machine worn on the body that takes your child’s blood pressure every 15 to 30 minutes during the course of a normal day. This information can help your child’s doctor see if treatment is working, and help you and your child manage hypertension.

  • Home blood pressure monitoring

    Our team can help you learn how to check and monitor your child’s blood pressure at home. Keeping a record of blood pressure measurements helps your child’s doctor see how well treatment is working and helps you manage your child’s health.

  • Medication management

    If your child needs medicines for high blood pressure, our team’s experience with the latest medicines allows us to know how to adjust doses and change medicines to help make sure your child gets the best results.

Nephrology

Nephrologists are doctors who specialize in treating diseases of the kidneys — the organs that help filter waste out of the blood and make urine. Seattle Children’s is a national leader in caring for babies, children and teens with kidney conditions, including the most complex disorders.

Interventional radiology

Interventional radiologists specialize in minimally invasive surgical procedures to find and correct problems, often deep inside the body, without the need for open surgery. They use imaging to guide their work, such as ultrasound, CT (computed tomography) scan or fluoroscopy.

Diagnostic radiology

Diagnostic radiologists specialize in using ultrasound, MRI (magnetic resonance imaging), and CT to diagnose blood vessel and organ problems deep inside the body. They create images that can be used by the interventional radiologists and surgeons to plan treatment, if necessary.

Surgery

Surgeons provide general and specialized surgical services to babies, children and adolescents. Our pediatric surgeons are national leaders in the use of minimally invasive techniques and can assess whether this type of surgery would be best for your child.
