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.
