The blood vessels are elastic tubules controlled by valves through which blood flows. Depending on the organ and the distance from the heart, these vessels should be of certain thickness to ensure proper blood supply, this maintains a constant normal pressure of the blood flow. In this condition, the blood vessels are narrowed, which results in reduced blood supply, affecting optimal function.
Both conditions result in narrowed blood vessels, and when the vessels supplying the kidneys are affected, there is reduced blood flow, which is interpreted as low blood pressure, leading to hormone release which increases the blood pressure. So, one of the main symptoms of renal artery stenosis is uncontrollable blood pressure.
Risk factors: The following factors put an individual at a higher risk of developing renal artery stenosis.
Symptoms: Though there are no obvious manifestations, uncontrolled high blood pressure can require renal artery stenosis to be ruled out. Some tests to be done include:
Treatment: This would be a two-pronged approach in terms of reducing risks and improving blood pressure.
In very severe cases, angioplasty and stenting may be required. A catheter (tube) is inserted into the affected blood vessel and a balloon is then inflated to open up the artery. A stent may also be placed to keep the vessel open and ensure optimal blood flow. This comes with its own complications and requires long-term care and monitoring.
