Renal Angioplasty: Restoring Kidney Blood Flow with Minimally Invasive Techniques
Renal angioplasty, a minimally invasive procedure, restores blood flow to the kidneys by widening narrowed renal arteries. Using balloons and stents, it alleviates hypertension and preserves renal function effectively.
This intervention is crucial for managing conditions like renal artery stenosis, enhancing kidney perfusion, and reducing the risk of complications such as kidney failure or cardiovascular events.
Assess the severity of renal artery stenosis through diagnostic imaging and patient history to determine the necessity of renal angioplasty.
Administer anesthesia or sedation to ensure patient comfort and relaxation during the procedure.
Gain access to the renal arteries by inserting a catheter, usually through the femoral artery in the groin area, and navigate it to the target site under fluoroscopic guidance.
Thread a guidewire through the catheter and advance it beyond the narrowed segment of the renal artery to facilitate balloon placement.
Inflate a balloon-tipped catheter at the stenotic lesion to compress the plaque against the arterial walls, widening the narrowed artery and restoring blood flow to the kidneys.
Inject contrast dye through the catheter and perform angiography to visualize the renal arteries, assessing the extent of stenosis before and after balloon inflation.
Evaluate the effectiveness of angioplasty in reducing stenosis, considering adjunctive procedures such as stent placement if residual narrowing persists.
Remove the catheter, close the groin incision, and monitor the patient for any post-procedural complications while providing appropriate follow-up care.
Renal angioplasty is employed across multiple medical disciplines, including interventional radiology, nephrology, cardiology, and vascular surgery. Specialists in these fields collaborate to diagnose and manage renal artery stenosis, a condition where the arteries supplying blood to the kidneys become narrowed or blocked.
