Dialysis Patients Who Has Collapsed Vein
Arterial Diversion: When an artery is connected to a vein, the vein walls thicken and become muscular (due to the new high arterial pressure). This makes finding the vein easier. More importantly, the large bore needles can be removed and pressure held, with clot forming in the muscular walls, to stop the bleeding. If the veins weren't muscular, putting the needle in and taking it out safely, aren't possible. ...Read moreSee 1 more doctor answer
Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more

If not and you need hemodialysis an interventional radiologist can likely evaluate you for and subsequently place a dialysis catheter directly into your inferior vena cava. Check with your nephrologist or surgeon for an appropriate referral. ...Read moreSee 1 more doctor answer
Fistula +/- aneurysm: Dialysis patients need a mature vein that can withstand repeated puncture which is created by diverting arterial flow into a nearby vein. Needling the same site causes a loss of pain nerve fibers, and thus patients prefer that site for repeated use. This can cause fibrosis and thinning of the wall at that site, resulting in aneurysmal dilatation. This is not in danger of rupturing. ...Read moreSee 1 more doctor answer
During dialysis why does the subclavian catheter have darker blood than in patients with a fistula?
For a dialysis, why is the subclavian catheter has darker blood rather than in patient with fistula?
Catheter vs fistula: An a-v fistula (avf) is a connection between an artery and a vein, that's why its called an a, for artery, v, for vein, fistula. Arterial blood has more oxygen, making it redder, than venous blood. A subclavian catheter has both blood tubes in the vein, where there is less oxygenated blood, as it does not have any arterial inflow. That's why it has darker blood than an avf. ...Read more
Open or endo: It can be done with tpa (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 moreSee 2 more doctor answers
I am dialysis patient. Doing since last 6 years. I had line in my neck n when they remove it got clot. Caz of that my fistula hand is swelled.
Venous Hypertension: The fistula causes increase blood flow through the veins draining the arm. If the veins are blocked or narrowed (both possible because of long term dialysis catheter) the increased pressure causes more fluid to collect in the arm and cause swelling. An interventional radiologist might be able to treat the narrowing with a baloon dilation and stunting. ...Read moreSee 1 more doctor answer
Itching: High phosphorus levels in a dialysis patient can lead to many issues. Usually most patients itch uncontrollably. However over time elevated phosphorus levels can alter bone structure, lead to calcium deposits on heart vessels and cause nerve damage throughout the body. ...Read moreSee 1 more doctor answer
