My mother has stage 3 cancer and was suppose to start chemo on nov 5th but now they want to keep her hospitalized and put a shunt in her neck why?

Call Mom's Doctor: The shunt you are referring to ("mediport", "portacath") is an implanted "permanent" IV that facilitates chemo administration, either due to poor patient IV access or the type of chemo given. This is an out-patient procedure & unrelated to your mom's dr's decision to keep her hospitalized. Please contact your mom's primary care dr or oncologist--they can clarify. I hope all goes well.

Port maybe?: A shunt for starting chemo would be unusual, but a chemotherapy port would be much more common. This is a special kind of an IV that goes into a large vein so that the chemo drugs don't damage the inner lining of small blood vessels. The tubing goes underneath the skin and ends in a small plastic reservoir called a port. This port also sits underneath the skin and can be accessed with a needle.
