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.

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 are the differences between anorectal fistula and abscess?

Differences : Usually, a perianal abscess is caused by an underlying fistula. A fistula is a tunnel that communicates the inside of the Anus and the outside skin.
