CV's (Central Venous Stenosis)

Question 1

4 Ursachen

Answer 1

Central venous lines inserted through the neck vessels

1. catheter for dialysis
2. central line for ICU
3. central line for chemo
4. central line for nutrition

And: pace maker wires.

Central venous stenosis (CVS) is known to occur following the insertion of central lines inserted through neck vessels in ICUs, peripherally inserted central catheters, chemotherapy catheters, pacemaker wires (30%–60% cases), and hemodialysis catheters, both noncuffed and cuffed catheters.

Question 2

Was sind die möglichen Folgen?

Answer 2

CVS is often asymptomatic in nondialysis patients, but can result in edema of ipsilateral extremity and breast when challenged by increased flow from an arteriovenous fistula (AVF) or AV graft. When brachiocephalic vein is involved, it can cause hemifacial swelling(published as a case report in this issue of journal, titled “innominate vein stenosis in association with ipsilateral hyperdynamic brachio-basilic fistula causing ipsilateral limb and hemifacial swelling).
