Dialysis Access Care
Patients on dialysis and dialysis specialists understand the critical importance of the vascular access in filtering toxins from patient’s blood by a dialysis machine. The ideal hemodialysis access is an artery to vein fistula that delivers high blood flow and easy cannulation.
Most fistula failures or graft failures are caused by scar tissue that causes a narrowing of the access. If we catch the problem in time, we can keep the access open and working longer.
Vascular Access Centers are dedicated to the care and maintenance of a patient’s dialysis access.
At Naadi Vascular and Interventional Center, our physician performs outpatient procedures to maintain optimal access performance.
Reasons for Referral
- Low clearance or low KT/V (a measure of adequacy of a dialysis treatment)
- Difficulty cannulating
- High venous pressures
- Low Arterial Pressures
- Excessive bleeding after dialysis
- Failure of a fistula to mature
- Decreased access blood flow by indirect measurements
Angiography is an X-ray exam of the arteries and veins to diagnose blockages and other blood vessel problems. An interventional radiologist performs this X-ray procedure, which is also called an angiogram. One of the most common reasons for angiograms is to see if there is a blockage or narrowing in a blood vessel that may interfere with the normal flow of blood through the body. In many cases, the interventional radiologist can treat a blocked blood vessel without surgery at the same time the angiogram is performed. Interventional radiologists treat blockages with techniques called angioplasty and thrombolysis.
Angioplasty is a minimally invasive procedure during which a small balloon catheter is threaded through your blood vessel to the access.
Thrombectomy (or declot)
Thrombectomy is a procedure which removes a blood clot through a catheter-guided procedure. Our specially trained physicians at Naadi Healthcare perform the outpatient procedure to remove the clot from the fistula or graft using an instrument specifically designed to do so, eliminating the need for a more invasive procedure.
Stenting involves a stent which is a small, wire mesh tube that expands, holding open a vessel to restore adequate blood flow through the AV fistula or graft. Stents are inserted through a catheter and remain permanently in place. Stents are used when angioplasty alone is not sufficient to keep the access open.
Dialysis catheters are an alternative dialysis access that can be used when a dialysis fistula or graft are not an option. Tunneled and non-tunneled Dialysis Catheter insertions, exchanges, removals and repairs are all done at Naadi Healthcare.
Ultrasound evaluation of fistula/graft
Ultrasound evaluation is a screening tool which provides the ability to examine the vascular structures deep under the skin and overcome the shortcomings of physical examination.
Ultrasound is invaluable for maintenance of a dialysis access and provides valuable information before venography or an intervention. An initial look with ultrasound will increase the ease and efficiency of an intervention.
