why do you need a fistula for dialysis
What are the benefits vs. risks? No surgical incision is needed only a small nick in the skin that does not have to be stitched closed. Angioplasty and Vascular Stenting: These procedures are performed using ; no is required in the majority of patients. You will be able to return to your normal activities shortly after the procedure. Catheter-directed Thrombolysis: Catheter-directed thrombolysis can greatly improve blood flow and reduce or eliminate the related symptoms and effects without the need for more invasive surgery. Thrombolysis is a safe, highly effective way of re-establishing circulation blocked by a clot. Thrombolysis is less invasive than conventional open surgery to remove clots and the hospital stay is relatively brief. Blood loss is less than with traditional surgical treatment and there is no obvious surgical incision. Any procedure where the skin is penetrated carries a risk of infection. The chance of infection requiring antibiotic treatment appears to be less than one in 1,000. There is a very slight risk of an allergic reaction if is injected. Any procedure that involves placement of a catheter inside a blood vessel carries certain risks. These risks include damage to the blood vessel, bruising or bleeding at the puncture site, and infection. Angioplasty and Vascular Stenting Major complications following angioplasty are uncommon. However, inserting the catheter can lead to injury of the artery or vein.
The balloon also poses a risk of blood clots or tearing the artery or vein. When angioplasty is performed, blockages can recur, although most of these arteries can be opened again successfully. This can also occur when a stent is placed in the artery at the time of the angioplasty. Heavy bleeding from the catheter insertion site may require special medications or a blood transfusion. A relatively rare complication associated with balloon angioplasty is abrupt vessel closure, or occlusion. This blockage in the area treated by the balloon angioplasty typically occurs within 24 hours of the procedure. If it happens, treatment with medication into the vessel to dissolve clots followed by angioplasty or stenting may be appropriate. In some cases, emergency bypass surgery may be needed. Other rare complications include heart attack and sudden cardiac death. Contrast material used during these procedures may cause renal failure, a decrease in kidney function, particularly if there is already some degree of decreased kidney function. There is a risk of damage to the fistula or graft. If the fistula or graft stops working, placement of a new access may be necessary, including possible placement of a dialysis catheter. Catheter-directed Thrombolysis There is a risk of infection after thrombolysis, even if an antibiotic has been given.
Whenever anticoagulant or are used, there is a risk that bleeding will occur elsewhere in the body. The most serious complication is
bleeding or bleeding in the head which can lead to stroke. In some cases the material that is blocking your vessel may move to another part of the vascular system. Usually this can be treated with further thrombolysis but sometimes may require surgery. There is a risk of kidney damage in patients with diabetes or other pre-existing kidney disease. An arteriovenous (AV) fistula is an abnormal connection between an artery and a vein. Normally, blood flows from your arteries to your capillaries to your veins. Nutrients and oxygen in your blood travel from your capillaries to tissues in your body. With an arteriovenous fistula, blood flows directly from an artery into a vein, bypassing some capillaries. When this happens, tissues below the bypassed capillaries receive a diminished blood supply. Arteriovenous fistulas usually occur in the legs, but can develop anywhere in the body. Arteriovenous fistulas are often surgically created for use in dialysis in people with severe kidney disease. A large untreated arteriovenous fistula can lead to serious complications. If you've had an arteriovenous fistula created for dialysis, your doctors will monitor you for complications. April 07, 2015
