Relationship between chest port catheter tip position and port malfunction after interventional radiologic placement.

Purpose: The relationship between catheter tip position of implanted subcutaneous chest ports and subsequent port malfunction was investigated. Tip movement from initial supine position to subsequent erect position was also evaluated.

Materials And Methods: Patients who underwent imaging-guided internal jugular chest port placement between July 2001 and May 2003 were identified with use of a quality-assurance database.
