The surgical treatment for RAS is typically reserved for specific cases with severe complications such as intractable Hypertension (high blood pressure) or deteriorating kidney function. Surgical interventions for RAS and its consequences include
This is one of the primary minimally invasive procedures used to treat RAS and its consequences. It is often considered when hypertension is not well controlled with medications or when there is a significant reduction in kidney function due to the stenosis.
A wire and catheter are placed into the artery at the top of the leg through a small needle puncture. The wire and catheter are advanced it to the site of the renal artery stenosis. balloon at the tip of the catheter is inflated within the narrowed portion of the renal artery, expanding it and improving blood flow. In some cases, a stent (a small, mesh-like tube) may be placed within the renal artery to keep it open and
maintain proper blood flow.
In severe cases of RAS with extensive arterial disease or complex anatomy, a surgeon may consider bypass surgery. This involves creating a new pathway for blood flow to the kidney, bypassing the narrowed or blocked renal artery using grafts.
The choice of surgical intervention depends on various factors, including the extent of renal artery stenosis, the degree of hypertension, the patient’s overall health, and kidney function. Successful treatment outcome is dependent on close working collaboration between Vascular Surgeon, Nephrologist, and Interventional Radiologist.
Its important to note that not all cases of RAS require surgical intervention, and many can be managed effectively with medications and lifestyle modifications.
