1 From the Departments of Radiology (R.K.H.) and Pathology (S.S.K.), and the Section of Pediatric Hematology/Oncology/Bone Marrow Transplant (N.K.F., R.H.G.), University of Colorado Health Sciences Center and the Children’s Hospital, 1056 E 19th Ave, Denver, CO 80218. From the 1999 RSNA scientific assembly. Received December 6, 1999; revision requested January 14, 2000; revision received March 17; accepted April 20. Address correspondence to R.K.H. (e-mail: harned.roger@tchden.org).

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.
