Interventional Nephrology Treatment and Care
Minimally Invasive Endovascular Intervention
The core philosophy of treatment in interventional nephrology at Liv Hospital is to solve complex vascular and renal problems through a “pinhole.” Instead of large surgical incisions that require long recovery times, we use specialized catheters, wires, and balloons introduced through a small needle puncture. This endovascular approach is the primary method for maintaining the health of dialysis accesses. By treating the problem from the inside of the vessel, we minimize trauma to the tissues, reduce the risk of infection, and ensure that the patient can return to their life—and their dialysis schedule—with minimal interruption.
Percutaneous Transluminal Angioplasty (PTA)
Angioplasty is the most frequently performed procedure in our interventional suite. When a diagnostic fistulogram identifies a narrowing (stenosis) that is restricting blood flow, the interventional nephrologist advances a specialized balloon to the site of the blockage. The balloon is then inflated to a specific pressure to stretch the vessel wall and restore the original diameter. At Liv Hospital, we utilize high-pressure balloons and drug-coated balloons (DCB). These advanced balloons release a medication (such as paclitaxel) into the vessel wall to inhibit the overgrowth of scar tissue, significantly extending the time before a repeat procedure is needed.
Thrombectomy and "Declotting" Procedures
If a dialysis access clots completely (thrombosis), it becomes an urgent clinical situation. At Liv Hospital, we perform “emergency declotting” to save the access and avoid the need for temporary neck catheters. We use a combination of:
Management of Central Vein Stenosis
Narrowing in the large veins of the chest (central veins) is a particularly challenging problem for long-term dialysis patients. At Liv Hospital, we treat these with large-diameter angioplasty balloons. In cases where the vein collapses immediately after the balloon is deflated (elastic recoil), we may place a vascular stent. These metal mesh tubes provide structural support to keep the central vein open, ensuring that the arm used for dialysis does not become swollen and painful. Our interventional nephrologists are experts in navigating these deep, complex vessels with high precision.
Tunneled Dialysis Catheter Placement and Management
For patients who cannot yet use a fistula or graft, a tunneled cuffed catheter serves as a temporary lifeline. Unlike emergency catheters, these are “tunneled” under the skin to provide a barrier against infection and are secured with a cuff. At Liv Hospital, we perform these placements under strict fluoroscopic guidance to ensure the tip of the catheter is perfectly positioned in the heart’s right atrium for maximum blood flow. We also perform “catheter exchanges” and “fibrin sheath stripping” to fix catheters that have become blocked or sluggish over time.
Endovascular AV Fistula Creation (EndoAVF)
One of the most exciting advancements in 2026 at Liv Hospital is the creation of a dialysis fistula without any surgery. Using the WavelinQ or Ellipsys systems, our interventional nephrologists can create a connection between an artery and a vein using thermal energy or radiofrequency through a catheter. This “EndoAVF” results in no surgical scar, less pain, and often a more reliable maturation process. This cutting-edge technology represents our commitment to providing the most advanced, least invasive options for our patients.
Renal Artery Stenting and Denervation
Interventional nephrology also treats the arteries that supply the kidneys. In cases of Renal Artery Stenosis, which causes severe hypertension and kidney failure, we can perform angioplasty and stenting to restore blood flow. Additionally, for patients with “resistant hypertension” that does not respond to medication, we offer Renal Denervation. This involves using a specialized catheter to apply radiofrequency energy to the nerves around the renal arteries, helping to lower blood pressure and protect the kidneys from hypertensive damage.
Post-Biopsy Care and Management
While the renal biopsy itself is a diagnostic tool, the “care” aspect involves the immediate management of the patient after the procedure. At Liv Hospital, we use a specialized “bedside monitoring” protocol. Following an ultrasound-guided biopsy, we apply pressure to the site and use advanced hemostatic patches to prevent bruising. The patient is monitored with serial blood pressure checks and ultrasound “spot-checks” to ensure there is no internal bleeding. This rigorous post-procedural care is what allows us to perform renal biopsies with such high safety ratings.
Integrated Care and Patient Safety
Patient safety is the cornerstone of our treatment model. We utilize “Triple-Safety” checks before every procedure, verifying access sites and patient data. Our hybrid operating rooms feature HEPA-filtered air and the lowest possible radiation settings. Furthermore, our nursing staff is specially trained in “Renal Recovery,” providing focused care for patients with compromised kidney function. By choosing Liv Hospital, you are choosing a facility where technology and compassion are woven together to provide the safest, most effective treatment for your renal health.
How Is Interventional Nephrology Treatment Performed at Liv Hospital?
At Liv Hospital, our interventional suites are designed to be a “Center of Excellence.” We combine the expertise of clinical nephrology with high-level interventional skills. Our physicians are not just technicians; they are doctors who understand your entire medical history, your medications, and your long-term goals. We utilize the most advanced imaging and catheter technologies of 2026, ensuring that every procedure is performed with the highest possible success rate. At Liv Hospital, we don’t just treat the access; we treat the patient.
