Findings and procedure details
By injecting 0.1-0.5ml of SonoVue in 20ml of saline through catheters or needles it is possible to demonstrate:
- the exact position,
size,
and echostructure of an abscess (multiloculated or uniloculated/quota of fluid component) (Fig.
1,2,3);
- communication between hepatic abscess/extrahepatic fluid collection and biliary tree (Fig.
4,5);
- catheter management,
including evaluation of percutaneous cholecystostomy (Fig.
6) and demonstration of dislodgement/occlusion (Fig.
7,8).
These data are of pivotal importance in:
A) Therapeutic Approach
-
Simple aspiration vs.
catheter positioning in case of small abscess cavities.
-
Use of single or multiple needle aspiration/catheter deployment according to abscess echostructure.
-
Need for endoscopic treatment (stenting/sphincterotomy) in case of biliary fistula.
B) Catheter Management
No complications ensue from intracavitary CEUS.
