Mesenteric Artery Disease or Stenosis
The mesenteric arteries (including the celiac, superior mesenteric and inferior mesenteric arteries) supply oxygen-rich blood to the intestines and other abdominal organs). When one or more of these arteries becomes narrowed or blocked, it can reduce blood flow to vital organs and cause a condition known as mesenteric artery ischemia.
Risk factors for mesenteric artery disease or stenosis
Risk factors for developing mesenteric artery disease or stenosis include:
- Smoking
- Family history
- High cholesterol
- High blood pressure
- Diabetes
- Obesity
- Sedentary lifestyle
Common symptoms may include abdominal pain (especially after meals), unintentional weight loss, bloating, nausea or vomiting. Also, at times, mesenteric artery disease can be asymptomatic (not causing symptoms) and may be found when you are being evaluated for another condition.
The most frequent causes are the buildup of plaque inside the arteries (atherosclerosis) or blood clots.
If you are experiencing symptoms or have been told you may have a blockage in your mesenteric arteries, we encourage you to schedule an appointment with one of our specialists. You may also request a referral from your trusted health care provider.
Mesenteric artery disease and stenosis treatment are personalized and may range from minimally invasive procedures, such as stenting, to more complex surgeries like bypass operations.
Renal Artery Disease or Stenosis
Renal artery stenosis (RAS) is the narrowing of one or both arteries that carry blood to your kidneys. These arteries are vital because they deliver oxygen-rich blood that helps your kidneys filter waste and regulate blood pressure. When they narrow, your kidneys may not get enough blood, which can trigger a rise in blood pressure and harm kidney function.
Causes of Renal Artery Disease or Stenosis
Causes of renal artery disease or stenosis include:
- Atherosclerosis: The most common cause. Fat and cholesterol build up on artery walls, forming plaques that restrict blood flow.
- Fibromuscular dysplasia: A less common cause, where abnormal growth in artery walls leads to narrowing.
Risk Factors include:
- Older age
- High blood pressure
- High cholesterol
- Diabetes
- Smoking
- Family history of heart disease
Symptoms of RAS
RAS often has no symptoms until it becomes serious. RAS may be found when you are being evaluated for another condition. Signs may include:
- Sudden or worsening high blood pressure
- Swelling from fluid buildup
- Kidney function decline
- A “whooshing” sound over the kidney area (heard with a stethoscope)
Diagnosis
Doctors may use:
- Blood and urine tests
- Ultrasound or Doppler imaging
- CT or MRI angiography
- Renal arteriography (a more detailed test using contrast dye)
Treatment
Options include:
- Medications to control blood pressure
- Lifestyle changes (diet, exercise, quitting smoking)
- Angioplasty or surgery to open narrowed arteries if your condition worsens to the point of needing intervention
Renal artery stenosis is serious but manageable with early detection and proper care. If you or your health care provider are concerned about possible renal artery stenosis, make an appointment with our office or have your health care provider refer you for evaluation and treatment.
