Renal (kidney) vascular disease includes a variety of conditions that affect the function of the veins of the kidneys. These conditions can cause damage to the tissues of the kidneys, kidney failure, and high blood pressure.
Renal Artery Stenosis
This condition occurs when an artery to a kidney is blocked. Renal artery stenosis (RAS) can lead to kidney failure and hypertension (high blood pressure).
Renal Artery Thrombosis
This condition occurs when a clot forms in a renal artery. Because blood flow to the kidney is blocked, kidney failure can result. If kidney failure occurs, dialysis or a kidney transplant will be needed.
Renal Artery Aneurysm
This condition occurs when there is a bulging, weakened area of the wall of an artery that leads to the kidneys. Many of these aneurysms are small (less than three-quarters of an inch), and do not cause any symptoms.
Atheroembolic Renal Disease
This condition occurs when a piece of plaque (hard buildup of fats, cholesterol, minerals, or other substances) breaks off from the aorta (major blood vessel of the heart) or another large blood vessel and travels through the blood stream. This condition commonly leads to poor kidney function in older people.
Renal Vein Thrombosis
This condition occurs when a clot forms in a vein that leads to a kidney.
You may be at risk for renal vascular disease if you have one or more of the following risk factors:
If you have renal vascular disease, you are at an increased risk for kidney failure, high blood pressure, and other serious complications.
Signs and symptoms of renal vascular disease can include:
- Bloody urine
- Hypertension that cannot be controlled by medication
- Mottling (discoloration) of the toes and feet
- Muscle aches
- Nausea or vomiting
- Pain and tenderness in the flank (area between the ribs and upper edge of hip bone)
- Pain in the abdomen
- Skin lesions
- Sudden onset of hypertension
- Sudden kidney failure when taking an angiotensin-converting enzyme (ACE) inhibitor medicine for blood pressure or another heart condition
- Unexplained kidney failure
- Unexplained weight loss
