Renal artery stenting is a minimally invasive procedure used to treat renal hypertension, a condition in which high blood pressure is caused by narrowing or blockage of the renal arteries that supply blood to the kidneys.
During the procedure, a small catheter is inserted into an artery in the groin and guided to the renal arteries. A small balloon is then inflated to widen the narrowed area of the artery, and a small metal mesh tube, called a stent, is inserted to help keep the artery open and maintain blood flow to the kidney.
Renal artery stenting can be an effective treatment for renal hypertension, particularly in cases where the condition is caused by atherosclerosis, a buildup of plaque in the artery walls. However, the procedure may not be effective for all types of renal hypertension, and it may be necessary to address other underlying conditions or factors that contribute to high blood pressure.
As with any medical procedure, there are some risks and potential complications associated with renal artery stenting, such as bleeding, infection, damage to the artery or surrounding tissue, or restenosis (re-narrowing of the artery). The decision to undergo renal artery stenting should be made in consultation with a healthcare provider, taking into consideration factors such as the severity of the renal hypertension, the patient’s overall health, and their individual treatment goals. Other treatment options, such as medication or lifestyle changes, may also be considered.
