An 8-F 24-cm-long apheresis catheter was placed in the basilic vein with imaging-guided percutaneous technique in 15 children undergoing leukapheresis for collection of autologous peripheral blood stem cells. There were no immediate or long-term complications. This is a low-morbidity procedure requiring minimal sedation that results in successful collection of peripheral blood stem cells and allows flow rates comparable to those with surgically placed central catheters.
