Unusual Malpositioning of Hemodialysis Catheter into the Hepatic Veins.
Summary of "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.

Medical and Biotech [MESH] Definitions
Veins which drain the liver.
A condition in which the hepatic venous outflow is obstructed anywhere from the small HEPATIC VEINS to the junction of the INFERIOR VENA CAVA and the RIGHT ATRIUM. Usually the blockage is extrahepatic and caused by blood clots (THROMBUS) or fibrous webs. Parenchymal FIBROSIS is uncommon.
Hepatic Veno-occlusive Disease
Liver disease that is caused by injuries to the ENDOTHELIAL CELLS of the vessels and subendothelial EDEMA, but not by THROMBOSIS. Extracellular matrix, rich in FIBRONECTINS, is usually deposited around the HEPATIC VEINS leading to venous outflow occlusion and sinusoidal obstruction.
Hemodialysis Units, Hospital
Hospital units in which care is provided the hemodialysis patient. This includes hemodialysis centers in hospitals.
Catheterization, Central Venous
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
Patients with central venous occlusion who are "tunneled catheter dependent" are a challenge for hemodialysis access. A relatively new option for them is the hemodialysis reliable outflow (HeRO) devic...
BACKGROUND:: The presence of communicating veins between adjacent hepatic veins may allow parenchyma-sparing hepatectomy. Taking advantage of improvements in ultrasound technology, such as e-flow moda...
BACKGROUND: The impact of hepatic venous anatomic variations on hepatic resection and transplantation is the least understood aspect of liver surgery....
To determine prevalence of central vein stenosis following catheterization with double-lumen temporary catheters, we performed color Doppler sonography in 100 consecutive patients. We detected central...
Total hepatic venous drainage into the left atrium is an extremely uncommon abnormality. We present a patient in whom the hepatic veins drained into the left atrium in the absence of other intracardia...
The search for communicating veins (CVs) between adjacent hepatic veins (HVs) has drawn its rationale from living donor liver transplantation (LDLT). Parenchymal sparing procedures althoug...
To determine if a protocolized approach to converting hemodialysis central venous catheters (CVC) to arteriovenous fistulae will improve rates of functioning AVF and decrease CVC use.
We are investigating a new way of administering alteplase to remove clots from hemodialysis catheters. Currently, alteplase is left to dwell inside the catheter between dialysis treatment...
This study will treat hemodialysis patients who have a central catheter that is thought to be infected with a specific bacteria (Gram positive bacteria).
The clinical study aims at providing data on antimicrobial efficiency and a supposed additional preventive effect on catheter-related infections of a catheter with antibacterial surface co...
