What Is Congenital Renal Artery Stenosis?

Congenital renal artery stenosis (CRAS) is a rare condition that occurs when the arteries that supply the kidneys with blood become narrowed. It is caused by a malformation of the artery walls and can lead to high blood pressure or kidney damage. CRAS is also known as renal artery stenosis or renal artery hypertension and affects both adults and children.

The condition is most commonly diagnosed in infants and young children, but it can also occur in adults. It is typically identified during an ultrasound or other imaging tests. In some cases, CRAS may not cause any symptoms and may only be discovered during a routine medical exam.

The severity of CRAS can vary greatly, depending on the extent and location of the narrowing. If the narrowing is severe, it can lead to high blood pressure and decreased kidney function. In some cases, it may even cause kidney failure.

Risk Factors for Congenital Renal Artery Stenosis

CRAS is believed to be caused by a genetic mutation, although environmental factors may also play a role. Risk factors for this condition include:

1. A family history of CRAS
2. Being born prematurely or with a low birth weight
3. Having a congenital heart defect or other birth defects
4. Having certain genetic syndromes, such as Turner Syndrome

CRAS is a rare condition, but it is important to be aware of the signs and symptoms. Early diagnosis and treatment can help prevent complications and improve long-term outcomes.
