Summary
Transcatheter arterial embolization (TAE) for liver cancer can lead to multiple intrahepatic aneurysms due to embolic agents. Radiologists should monitor for this potential complication following TAE procedures.
Area of Science:
- Interventional Radiology
- Hepatobiliary Medicine
- Vascular Surgery
Background:
- Hepatocellular carcinoma (HCC) is a primary liver malignancy.
- Transcatheter arterial embolization (TAE) is a common treatment for HCC.
- Complications of TAE require careful consideration and monitoring.
Purpose of the Study:
- To investigate the mechanism behind multiple intrahepatic aneurysm formation after TAE.
- To describe the incidence and characteristics of these aneurysms.
- To raise awareness among radiologists about this TAE complication.
Main Methods:
- Retrospective analysis of five HCC patients who underwent TAE.
- TAE utilized gelatin sponge particles and iodized oil as embolic agents.
- Repeat angiography was performed 25-45 days post-TAE to assess for aneurysms.
Main Results:
- Multiple aneurysms (3-14) ranging from 1-6 mm were observed in hepatic artery branches.
- Aneurysms were typically found in third-to sixth-order branches.
- Most aneurysms resolved on follow-up, but some persisted or enlarged; no ruptures occurred.
Conclusions:
- Embolic agents used in TAE are speculated to be the primary cause of intrahepatic aneurysm formation.
- Radiologists must be vigilant for this potential complication.
- Awareness and monitoring are crucial for managing post-TAE vascular changes.
