What Does An Av Fistula For Dialysis Mean
Arteriovenous fistul: It is an arteriovenous fistula. It is a surgical connection of an artery and a vein. Once "mature", it is where they insert the needles for the blood to flow to the dialysis machine. It can take 3 months or so from "creation" until it is ready to use. ...Read moreSee 2 more doctor answers
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
Growth for dialysis: A primary arterio-venous fistula ( that means where an artery and a vein have been sutured directly into each other as opposed to an interposition graft) takes some time for the vein to grow larger.The size of the vein is important because it allows the flow requirements of dialysis.This often takes a month or two to happen. ...Read more
"short circuit": A patient who is on dialysis needs the machine to clean toxins from the blood that the kidneys usually do. The patient's blood needs to get out of the body, through the machine, and back into the body. A dialysis fistula is made by sewing a vein to an artery. This short-circuits the blood flow and the vein becomes dilated because it experiences arterial pressures. This can be used for access. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Two methods : There are two methods: mechanical or chemical. Occasionally both methods are used. In general, the doctor accesses the av graft or fistula with a needle and places a tube into the graft. He then uses wires and catheters to cross the clot and inject clot busting meds. There are devices he can use that also break up clot. Or, he can open the graft and use special balloons to pull clot out. ...Read moreSee 1 more doctor answer
A fistula: A fistula for dialysis is created by connecting a vein in the arm to an artery and giving it usually 6-8 weeks to mature. A good fistula is anatomically not visible but felt through the thrill and bruit it creates. So you should not be able to know the location of a fistula if it is well done. ...Read moreSee 1 more doctor answer
Leaky valve: When your heart pumps blood, the mitral valve closes, and blood is pumped out an open aortic valve. If you mitral valve shows 'insufficiency', there is some degree of leak allowing blood to be pumped back up to the .And function. Talk to your doc about your particular diagnosis. ...Read more
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 moreSee 4 more doctor answers
Here are some ...: Organ auto-transplant is to move a locally damaged organ - intentionally or unintentionally - to a new site so such organ will / may continue to survive & function. For kidneys, such need usually takes place for insufficient ureter or artery. How is that related with ileostomy reversal? It would be most likely to make the shortened ureter to function. For individual situation, ask Doc. ...Read more

Valves malfunction.: Venous stasis is due to venous insufficiency which is a result of the valves in the venous system malfunctioning . This can be due to the valves in the deep system, superficial system or connecting system. Deep system valve malfunction could be due to prior clots, superficial problems could lead to varicose veins and perforator malfunction could lead to venous ulcers. ...Read moreSee 4 more doctor answers

The hypertrophy can be seen on ecg as the LVH pattern. One can not however read 'obstruction' on an ecg, it can be suspected but not diagnosed by ecg alone absent other information. ...Read more

Retroperitoneal absc: Is there fluid "around" the kidney? Was this seen on ct or mri? Has this baby had fevers, illness, any ultrasounds demonstrating "fluid around the kidney"? If not, then i also would agree with answer that this sounds like a collection of urine backing up in the kidney because of a blockage of outlet, most commonly vur (vesico-ureteral reflux) , which causes the kidney to enlarge. ...Read moreSee 4 more doctor answers
Risk: If an artery is 25-50% narrowed, you would generally not have any symptoms except under extreme exercise. However, the fact that it is partially blocked implies that you are at risk for progression - either gradual due the risk factors that cause the partial narrowing or suddenly when platelets stick to the area and cause complete blockage. ...Read more
A fistula is an abnormal connection between two places. Most commonly, it originates somewhere in the intestine and communicates to another location in the intestine or in the skin.
