Background
The postprocedural changes seen on body imaging scans after interventional radiology (IR) procedures can be difficult to interpret, especially those seen after less commonly performed procedures. Unfamiliarity with common IR hepatobiliary procedures and expected postprocedural changes may cause the radiologist to mistake expected changes as pathologic. In addition, knowledge of the expected changes is important to help radiologists dictate accurate reports to help further guide treatment.
Educational Goals / Teaching Points
The goal of this case-based pictorial is to identify post-IR procedure changes on body imaging scans as well as the appearance of more common complications.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Indications for intervention, postprocedure imaging findings, postprocedure imaging reporting, potential complications, and other considerations of the more common hepatobiliary interventions will be discussed. This will include percutaneous biopsy, transcatheter arterial chemoembolization, trans-jugular intrahepatic portosystemic shunt, cholecystostomy tube, biliary stents, portal vein embolization, among others.
Conclusion
Post-IR procedural changes seen on body imaging scans after hepatobiliary procedures can present challenges in interpretation. Identifying and reviewing common post-IR procedural changes as well as some of the more common complications can help radiologists dictate accurate reports that guide further treatment.
