Comparative Study
Impact of short-term hemodialysis catheters on the central veins: a catheter venographic study.
To determine the incidence of pericatheter sleeve formation, thrombus formation, and stenosis of the central veins in hemodialysis patients with temporary catheters. ⋯ This study showed that even short-term catheters result in significantly high rates of pericatheter sleeve and thrombus formation which are two of the important causes of catheter malfunction. The IJV route is known to be much safer than the SCV route with respect to stenosis formation in the vein in which the catheter is inserted; however, the result showed no differences between the two routes with respect to frequencies of pericatheter sleeve formation, thrombus formation, and BCV stenosis. These findings remind us again that we should avoid unnecessary catheter insertion even for short-term in these chronically ill patients.
