Illustration depicting AV fistula during hemodialysis. AV (arteriovenous) fistulas are recognized as the preferred access method. To create a fistula, a vascular surgeon joins an artery and a vein together through anastomosis. Since this bypasses the capillaries, blood flows rapidly through the fistula. One can feel this by placing one's finger ...
Surgically created AV fistulas work effectively because they: Have high volume flow rates (as blood takes the path of least resistance; it prefers the (low resistance) AV fistula over traversing (high resistance) capillary beds). Use native blood vessels, which, when compared to synthetic grafts, [5] are less likely to develop stenoses and fail.
Vascular access steal syndrome is a syndrome caused by ischemia (not enough blood flow) resulting from a vascular access device (such as an arteriovenous fistula or synthetic vascular graft–AV fistula) that was installed to provide access for the inflow and outflow of blood during hemodialysis.
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.
Dialysis centers in the United States are rolling out COVID-19 antibody treatments this week, a new path for delivery of Eli Lilly and Regeneron drugs approved for emergency use but facing ...
Complication of catheter insertion rarely causes arteriovenous fistula. It is usually caused by brachial artery puncture because brachial artery is located between two brachial veins. [6] Surgically created Cimino fistula is used as a vascular access for hemodialysis. Blood must be aspirated from the body of the patient, and since arteries are ...

Gen Zers said they planned to spend about 21% more than last year for the holidays, according to the report's survey of 1,000 U.S. consumers. In contrast, researchers found millennials – born ...
