Aspiration vs Drainage
•
Image-guided percutaneous aspiration is defined as
evacuation or diagnostic sampling of a fluid collection with the
use of a catheter or a needle during a single imaging session,
with removal of the catheter or needle immediately after the
aspiration.
•
Image-guided percutaneous drainage is defined as the
placement of a catheter with the use of image guidance to
provide continuous drainage of a fluid collection, using access
pathways that may be either transorificial (eg, transrectal,
transvaginal, peroral) or transcutaneous. It includes localization
of the collection and placement and maintenance of the
drainage catheter or catheters. It may be performed during a
single session or as a staged procedure during multiple sessions.
