In anatomy, a fistula (pl.: fistulas or fistulae /-l i,-l aɪ /; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other.
The Malone antegrade continence enema (MACE), used to treat fecal incontinence, is like the Mitrofanoff procedure as it uses the Mitrofanoff principle and, thus, can be considered an analogous procedure. [8] As fecal and urinary incontinence frequently co-exist, a MACE is often created at the same time as a continent catheterizable urinary ...
The complications are fewer than with other access methods. If a fistula has a very high blood flow and the vasculature that supplies the rest of the limb is poor, a steal syndrome can occur, where blood entering the limb is drawn into the fistula and returned to the general circulation without entering the limb's capillaries. This results in ...
A fistula or graft is dissected away through a small incision. An inflated intra-luminal balloon is used to provide a solid structure (thus allowing for precise sizing of the band), and a Prolene suture is tied around the access in the region of the balloon.
Life in 2021 returned to something resembling normal, with stadiums again full, lockdowns eased and kids back in class. But there were also events to remind us that true normal still remains a way ...

[6] Before the Cimino fistula was invented, access was through a Scribner shunt, which consisted of a Teflon tube with a needle at each end. Between treatments, the needles were left in place and the tube allowed blood ...
