Unusual malpositioning of hemodialysis catheter into the hepatic veins.

Malpositioning of long-term hemodialysis catheter is a known complication that may lead to a gradual decline in blood flow. We report two rare catheter malpositions in the hepatic veins in two patients with end-stage renal disease in whom a dialysis catheter was inserted through the left external jugular vein and the right external jugular vein. Because of gradual reduction of catheters' blood flow, an angiography was performed, which confirmed catheters' tip positioning into the hepatic veins. The catheters were replaced in the correct site.
