How do physicians de-clot an av fistula for dialysis patients?

Open or endo: It can be done with tpa (alteplase) (a high-potency medication to dissolve blood clot) and a rotor-rooter device inserted through a needle stick in the access. I tend to make a small incision to remove the clot with a balloon catheter, then do an angioplasty on the area of stenosis (narrowing) which you usually find in the vein or graft. ...Read more

What does it mean to have av fistula in left arm?

Connect Vein&Artery: This is when a vein is surgically connected to an artery (end-to-side anastomosis). This maintains blood flow to the hand while diverting blood into the vein. The vein becomes pressurized to arterial pressure and had much higher blood flow. Over time its size will double and its walls thicken so that it can be accessed for dialysis. Left arm is most often used because it is the non-dominant arm. ...Read more

Is an av fistula permanent or temporary?

Permanent w/o repair: An AV fistula, or arterial-venous fistula, is an abnormal connection between an artery & vein that allows high pressure arterial blood to travel into the low pressure venous system. It can be caused by traumatic blood vessel injury or purposely created surgically by a doctor (e.g for dialysis access). An AV fistula is always permanent unless repaired surgically or with covered stenting of vessels. ...Read more
