Abstract
Purpose
To assess the role of intracavitary contrast-enhanced ultrasound (IC-CEUS) as a focused ultrasound (US) examination aimed at supporting a single physician in the management of interventional procedures for abdominal fluid collections/abscesses.
Methods
In 43 patients (27 M/16 F, median age 68 years, range 35–91), a single physician performed catheter drainage (42) or needle aspiration (3) for the following: 14 infected abdominal fluid collections, 11 non-infected abdominal fluid collections, 9 pyogenic liver abscesses, 8 gallbladder empyema, and 3 infected pancreatic fluid collections. IC-CEUS (0.1–0.2 mL of SonoVue in 20 mL of saline) was carried out during catheter/needle placement and during the follow-up for catheters left in place.
Results
Immediate IC-CEUS allowed to verify the (1) correct positioning of the needle/catheter inside the target in all cases and (2) communication with adjacent structures so as to choose a proper treatment in 21% of the cases. Follow-up IC-CEUS aided in the management of 40 catheters left in place. Appropriate treatment was implemented in 19.3% of the cases because of the presence of biliary fistulas and gallbladder perforation. IC-CEUS helped the physician with the appropriate timing of catheter removal by providing information on catheter malfunction (due to obstruction/dislodgement) and the size of residual undrained cavities. No side effects were registered following IC-CEUS.
Conclusion
Even if not strictly performed at bedside, IC-CEUS may represent an example of point-of-care ultrasound since it allows an interventional clinician to assess needle/catheter placement success, make treatment decisions, and choose the optimal timing for catheter removal with low costs and without side effects.
