What is the difference between a fistula and a shunt?

What is the difference between a fistula and a shunt?

Dialysis shunts.: A shunt is a term for the connection that shunts blood from an artery to a vein, bypassing the microscopic network in the tissues that normally connect them. This allows a high blood flow access for pulling blood from the body to the dialysis filter. A fistula is a shunt that has a direct connection of a native artery and native vein, rather than using an artificial tube to make the connection. ...Read more

I'm wondering why can't you do an IV on a fistula/shunt and if you do are there any complications?

Here's why: Here's why we don't place IVs in fistula/shunt. First, blood flow is high pressure in them and would force blood backward through IV. Second, placing an IV into the fistula/shunt by staff who aren't used to it often injures the fistula/shunt resulting in issues like pseudoaneurysms. Shunts/fistulae are important so we save them for your dialysis! ...Read more

What happens if shorting of artery and vein (using fistula/decron shunt), will there be circulatory problems, gangrene or will there be no effect?

What happens if shorting of artery and vein (using fistula/decron shunt), will there be circulatory problems, gangrene or will there be no effect?

Complex: Arteriovenous fistula, shunt, graft have hemodynamic effects.
Usually done in forearm or arm with excellent alternate flow called collateral and checked prior to surgery. Total blood flow is increased and has cardiac effects, also venous dilation, and palpable flow thrill are part of the local effects. ...Read more

Can any doc tell me what's the difference between anorectal fistula and abscess?

Anal abscess/fistula: True perianal abscess arise from anal glands just up inside the anus. The gland gets blocked but pressure builds up and a tract is formed leading out from the gland to the perirectal spaces (anal fistula). An abscess forms. When the abscess is drained the tract (or fistula) dries up 50% of the time. In the other 50% it remains as an anal fistula, manifesting as a chroninc draining sinus. ...Read more

So my neurosurgeon said my shunt is fine but it is causing me pain when I try to sleep she said just wait 2 more weeks what difference could that make? I need to sleep more then 3 hours a night

So my neurosurgeon said my shunt is fine but it is causing me pain when I try to sleep she said just wait 2 more weeks what difference could that make? I need to sleep more then 3 hours a night

Sleep is Important: There are two ways to approach this issue. If the pain is occurring only when you are lying down, there is a chance that the pressure is going up with that position, which could mean the shunt opening pressure is set too high. If pain at the shunt site is the problem, you might ask your neurosurgeon if it would be reasonable to use pain medications or a sleep medication for a few weeks. ...Read more
