Renal Artery Stenosis Stent is very safe and highly advanced method which has proven results for the treatment of Renal Artery Stenosis. Stenting has a high success rate when it comes to treatment.
Renal Artery Stenosis refers to the narrowing of one of more of the blood vessels leading to the kidneys. This medical condition can lead to a high blood pressure which is difficult to control. This narrowing is more of a blockage of the path which is caused by a plaque. This plaque comprises of mainly fats, cholesterol and other such materials. With time, these materials keep building up on the walls of the renal artery thus narrowing the path and eventually creating a blockage. Thus the victims of this medical condition are old people because it takes time to builds up the plaque.
Generally there are no symptoms for this vascular condition therefore it is hard to tell whether or not you are suffering from Renal Artery Stenosis or not; although if your high blood pressure is very hard to control, it might be a case of this medical condition. You need to go through special tests before you can get to know the exact picture. There are various treatments for this medical condition but the most advanced technique used nowadays to cure it is that of using a Stent.
A Stent is an artificial tube that is inserted inside the body at the point where there is any constriction in the blood vessels to counteract it. It is a kind of a wire mesh which is capable of expanding itself. This expansion property of the tube is used to prevent the narrowing or the blocking of the blood vessel. Renal stent is used to treat the similar medical conditions in the kidneys chiefly the Ureter. This Stent is held in its place by two coils that are present at each of the two ends of the stent.
A complete medical imaging of the person is done when the need is felt by the doctor to treat the patient using this Stenting method. This imaging process gives a clear and complete picture of all the blood vessels surrounding the kidneys so the exact location for the placement of the Renal Stent can be determined. To further pinpoint the location of the constriction in the blood vessel, an angiography is performed. In this a dye is used to track the flow of blood through the blood vessels. Using a tracer the flow of dye can be recorded and the constriction pinpointed.
But this kind of treatment requires extra care on the part of the patient. He should always follow and ask for instructions from his doctor post the operation. Regular and periodic visits to the doctor for examination of the stent are crucial. This is because the renal stent can dislocate or drift from its place if not taken care of properly. Moreover the stent generally develops clots around itself therefore asking and following the instructions regarding the specific medication course to be followed by the patient is extremely important.
