What Does A Dialysis Fistula Actually Do
"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
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
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
Cardiac reserve: Let's make an analogy to 'army reserve'. These army men are just standby without active duty. But when there is a war, these people will be involved. Similarly, you don't use cardiopulmonary reserve during normal activities. During stress or illness, you want your lungs to take as much air/oxygen as possible and increase heart rate to maintain adequate blood flow (cardiac output) to tissues. ...Read more
Please answer! what do docs mean when they say a heart valve is damaged? How long does a person survive with this?
Complicated: Valves are either blocked or leaky or both. Damage is typically due to aging or calcification, congenital conditions, infections or structural deterioration. Some people live years with minor damage others much less. Survival depends on how severe damage is. ...Read more
Hard to Answer: Probably best to ask someone you know about who is on dialysis, and would like to talk about it. There are over 500, 000 patients receiving dialysis in the us each year. It should not be hard to find a dialysis patient. You could also call a local dialysis unit--and even volunteer to help out. ...Read moreSee 1 more doctor answer
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
Meniere's symptoms: Meniere's disease is caused by fluid build up in the inner ear which disrupts hearing and balance. Patients experience a sensation of fullness or pressure, hearing loss and ringing (tinnitus) in the affected ear, often followed by dizziness or vertigo. Episodes of dizziness can be severe and debilitating. Episodes can occur at long intervals, or can be frequent. Hearing loss can worsen over time. ...Read moreSee 1 more doctor answer
Many things: It has a much finer filtering mechanism to selectively remove waste products. The kidney also has endocrine function meaning it can respond to other hormones in the body such as parathyroid hormone to keep the bones healthy and aldosterone or vasopressin that aid in salt and water control. The kidney also can produce hormones that stimulate the bone marrow and produce vitamin d. ...Read moreSee 2 more doctor answers
Altered normal cell: normal cells can be affected by viruses or carcinogens to develop mutations in certain genes termed "oncogenes" Certain of these genes like p53 allow cells that have a DNA mutation to slow their rate of division to allow corrections. With mutated genes the corrections not made and mutation is passed to divided cells. There are enzymes like telomerase to allow the mutated cell to have immortality. ...Read more
What do you think about cord banking? Is it worth the money? How often does a patient use it/need it?
Cord banking: Umbilical cord blood contains immature stem cells, which may be useful later in life to treat certain diseases. Although it is currently possible to use them to treat some hematologic blood diseases, the promise of using stem cells to treat diseases is still mostly in the future, and has not yet proven useful in most diseases. I am cautiously optimistic that this will be useful in the future. ...Read more
Severe Constipation: Fecal impaction typically indicates that stool has collected in your rectum and formed a large bolus or ball of stool. This typically requires "disimpaction" which is digital (with a finger) removal of this stool. This can in fact require sedation. Ironically severe impaction can cause fecal incontinence or soilage from liquid stool leaking around the large bolus of stool. ...Read moreSee 1 more doctor answer

What does "pumping the reservoir" of a vp shunt really mean? Is it possible to know exactly when it's draining?
Pumping a shunt: A vp shunt should not be pumped except under a neurosurgeon's care. No, it is not possible to know exactly when it is draining except with highly sophisticated equipment. Many of the shunts today do not have a reservoir and may not be pumped. Pumping may cause over draining and lead to serious complications. ...Read more
No it does not try: If magnesium citrate does not work that does not mean you have blockage.If it is being used foe constipation you may need lifestyle changes like eating more fiber in your diet like20to35grms of fiber per day and increased fluids if that does not work you may use other over the counter laxatives like stimulant laxatives and or stool softners. ...Read more
Did not integrate: Typically this means that the bone did not grow to the implant surface in order to lock it into place. So, the implant becomes mobile (loose) and will work its way out or will need to be removed. Can also "fail" over time due to excess occlusal (biting) forces, bone/tissue infection, and sometimes for unknown reasons. Success rates are in the high 90's %. ...Read moreSee 10 more doctor answers
Fistula? Hemodial?: Your question is confusing. Did you get a fistula formed to be cannulated for hemodialysis or are you getting hemodialysis treatment and you have some form of fistula on your body somewhere i.e. colocutaneous fistula, perianal fistula, intestinal fistula..... What do you have? ...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. A fistula can develop after abdominal surgery, with inflammatory bowel disease, cancer, anorectal abscess, and ...Read more
