Dialysis access flow phenomenon demonstrated via an internal jugular central venous catheter uniquely positioned within a superior vena cava stenosis

摘要

IGHT internal jugular vein central venous catheter placement is routine for cadaveric renal transplantation to assist intraoperative assessment of cardiac preload and intravascular volume status.1 The presence of a surgical upper extremity arteriovenous fistula for hemodialysis can significantly alter flow patterns in regional vessels and both the arterial and venous circulation. This can be compounded by variations in venous anatomy.
