Simple definition: Difference between vas cath and permacath

Don't know a whole lot about the subject, but I will give it a try.

Vas cath or Permacath are both temporary catheters used for hemodialysis until a more permanent access has time to "mature" (arteriovenous fistula or Arteriovenous (AV) Graft). Sometimes these catheters are used in more chronic hemodialysis situations, when fistula or graft access cannot be obtained.

The vas cath is a specially-designed catheter with 2 or 3 lumens that is inserted into the subclavian, internal jugular, or femoral vein and can be used immediately (after x-ray confirmation). The vas cath is similar to a huge central venous line, and requires no tunneling.

The Permacath is also used for short-term and immediate hemodialysis treatment. This procedure is a little more involved and requires tunneling under the skin. The Permacath will last anywhere from one to twelve months.

Both types of catheters should never be used for anything but dialysis (except in an emergency, when no other IV access can be found).
