Dialysis fistula/graft declotting interventions improve blood flow in fistula and grafts – artificial blood vessel connections used to facilitate kidney dialysis, a treatment that uses a special machine to remove waste materials from the body. These connections can clog or narrow and require angioplasty and vascular stenting or catheter-directed thrombolysis.Your doctor will tell you how to prepare and whether you will be admitted to the hospital. Inform your doctor if there’s a possibility you are pregnant and discuss any recent illnesses, medical conditions, allergies and medications you’re taking.

You may be advised to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) or blood thinners several days prior to your procedure. Leave jewelry at home and wear loose, comfortable clothing.
You may be asked to wear a gown. What are Dialysis and Fistula/Graft Declotting and Interventions?Dialysis fistula/graft declotting and interventions are procedures performed to improve or restore blood flow in the and placed in the blood vessels of patients.Dialysis is a process used to treat patients whose kidneys are not working properly. What are some common uses of the procedure?These procedures are used to treat:. narrowing of dialysis fistula or grafts. When there is decreased flow in a graft or fistula, angioplasty or angioplasty with vascular stenting may be performed. of dialysis fistulas or grafts.
When blood does not flow smoothly, it can begin to, turning from a free-flowing liquid to a semi-solid gel, called a blood clot or thrombus. When blood clots in a fistula or graft prevent dialysis from being performed, catheter-directed thrombectomy (clot removal), or thrombolysis with clot-dissolving drugs may be performed. How should I prepare?Tell your doctor about all the medications you take, including herbal supplements.
List any allergies, especially to, or to. Your doctor may tell you to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) or blood thinners before your procedure.Tell your doctor about recent illnesses or other medical conditions.Women should always inform their physician and x-ray if there is any possibility that they are pregnant. Many imaging tests are not performed during pregnancy so as not to expose the to radiation. If an x-ray is necessary, precautions will be taken to minimize radiation exposure to the baby. See the for more information about pregnancy and x-rays.You will receive specific instructions on how to prepare, including any changes that need to be made to your regular medication schedule.You will be given a gown to wear during the procedure.
What does the equipment look like?In these procedures, x-ray imaging equipment, a balloon catheter, catheter, guide wire, sheath, stent and a medical device that breaks up or dissolves blood clots may be used.The equipment typically used for this examination consists of a radiographic table, one or two x-ray tubes and a television-like monitor that is located in the examining room. Fluoroscopy, which converts x-rays into video images, is used to watch and guide progress of the procedure.
The video is produced by the x-ray machine and a detector that is suspended over a table on which the patient lies.A balloon catheter is a long, thin plastic tube with a small balloon at its tip. A stent is a small, wire mesh tube. Balloons and stents come in varying sizes to match the size of the diseased blood vessel.A catheter is a long, thin, hollow plastic tube, about as thick as a strand of spaghetti. These catheters are designed so that blood dissolving medications can be delivered successfully within the blood clot. There also are medical devices that can be used to dissolve the clots mechanically. Your interventional radiologist will decide which technique is most appropriate for you.A guide wire is a thin wire used to guide the placement of the diagnostic catheter, angioplasty balloon catheter and the vascular stent.
A sheath is a vascular tube placed into the fistula or graft and allows easy catheter exchanges during these procedures.Stents are specially designed metal mesh tubes that are collapsed when they are inserted into the body and then expanded inside the vessel to prop the walls open. In some cases the stent may have an artificial fabric covering.Other equipment that may be used during the procedure includes an line (IV), ultrasound machine and devices that monitor your heart beat and blood pressure. How does the procedure work?: Using imaging guidance, an inflatable balloon mounted at the tip of a catheter is inserted through the skin into the fistula or graft and advanced to the blockage.
There, the balloon is inflated and deflated. In this process, the balloon expands the vein or artery wall, increasing blood flow through the fistula or graft.
A stent may be placed to hold the vessel open.: Using x-ray guidance and a that helps show the blood vessel, your interventional radiologist will insert a catheter through the skin into a vessel (artery or vein) and direct it to the thrombosis, or blockage. The blood clot will then be dissolved in one of two ways:. by delivering medication directly to the blood clot (thrombolysis). by positioning a mechanical device at the site to break up the clot (thrombectomy). How is the procedure performed?This procedure is often done on an outpatient basis.
However, some patients may require admission following the procedure. Ask your doctor if you will need to be admitted.You will be positioned on the procedure table.You may be connected to monitors that track your heart rate, blood pressure, oxygen level and pulse.A nurse or will insert an (IV) line into a vein in your hand or arm to administer a sedative. This procedure may use moderate sedation.
It does not require a breathing tube. However, some patients may require.The area of your body where the catheter is to be inserted will be sterilized and covered with a surgical drape.Your physician will numb the area with a. This may briefly burn or sting before the area becomes numb.A very small skin incision is made at the site.Angioplasty and Vascular Stenting: After local anesthetic, a sheath or short tube is first inserted into the fistula or graft.
This tube is similar in size to the needles used during regular dialysis sessions.Guided by x-rays, the catheter is then inserted through the sheath and advanced until it reaches the site of the blockage. Once the catheter is in place, contrast material will be injected and an angiogram or x-rays will be taken of the blocked vessel to help identify the site of the blockage.With x-ray guidance, a guide wire will then be moved to the site, followed by the balloon-tipped catheter. Once it reaches the blockage, the balloon will be inflated for a short period of time. The same site may be repeatedly treated with the same balloon, a different balloon, or the balloon may be moved to other sites.Additional x-rays will be taken to determine how much the blood flow has improved. When your interventional radiologist is satisfied that the vessel has been opened enough, the balloon catheter, guide wire and catheter will be removed.Many angioplasty procedures also include the placement of a stent, a small, flexible tube made of wire mesh. The stents are positioned and expanded with a balloon. What will I experience during and after the procedure?Devices to monitor your heart rate and blood pressure will be attached to your body.You will feel a slight pinch when the needle is inserted into your vein for the IV line and when the local anesthetic is injected.
Most of the sensation is at the skin incision site. This is numbed using local anesthetic.
You may feel pressure when the catheter is inserted into the vein or artery. However, you will not feel serious discomfort.If the procedure is done with sedation, the intravenous (IV) sedative will make you feel relaxed, sleepy and comfortable for the procedure.
You may or may not remain awake, depending on how deeply you are sedated.You may feel slight pressure when the is inserted, but no serious discomfort.As the passes through your body, you may feel warm. This will quickly pass.Angioplasty and Vascular Stenting: It is common for patients to feel some discomfort when the balloon is inflated because the blood vessel is being stretched.
Discomfort is more prominent when veins are dilated, as is usually the case with dialysis access procedures. Your discomfort should lessen as the balloon is deflated.After the procedure, your access site into the fistula or graft will be checked for bleeding or swelling and your blood pressure and heart rate will be monitored.After you return home, you should rest and avoid lifting heavy objects and strenuous exercise for at least 24 hours. You should avoid smoking permanently (since this is a major cause of atherosclerosis). If bleeding begins where the catheter was inserted, you should lie down, apply pressure to the site and call your physician. Any change in color in your leg or arm (depending on where your dialysis access is located) and any pain or a warm feeling in the area where the catheter was inserted should be promptly reported to your physician.After an angioplasty or stent placement procedure you may be instructed to take one or more medications (such as aspirin, or blood thinners such as Plavix®, Lovenox® or Coumadin®) for a period of time. These medications can prevent blood clots from forming at the site of treatment during healing. The effect of Coumadin® will be monitored with frequent blood tests.In general, may be safely performed following stent placement, but make sure that you notify the MRI department that you have recently had a stent.
Although stents used today may be considered safe for MRI, you may need several weeks after stent placement for MRI to be safe. Metal detectors will not affect a stent.Catheter-directed Thrombolysis: Some patients experience some side effects after thrombolysis. Pain is the most common and can readily be controlled by pain medication given orally or administered through your IV.
