Summary
A 57-year-old man developed multiple hepatic artery aneurysms after chemoembolization for liver cancer. This case suggests chemoembolization may induce drug-induced arteritis, leading to aneurysm formation.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Hepatology
Background:
- Hepatocellular carcinoma (HCC) is a primary liver cancer.
- Chemoembolization is a standard treatment for unresectable HCC.
- Hepatic artery aneurysms are rare but serious complications.
Observation:
- A 57-year-old male patient presented with liver dysfunction and right lobe hepatoma.
- The patient underwent chemoembolization for hepatoma treatment.
- Follow-up angiography revealed multiple peripheral hepatic artery aneurysms.
Findings:
- The aneurysms appeared in the chemoembolized region 35 days post-procedure.
- The likely cause of the aneurysms was drug-induced arteritis.
- This suggests a potential complication of chemoembolization therapy.
Implications:
- Chemoembolization may lead to iatrogenic hepatic artery aneurysms.
- Careful monitoring is needed after chemoembolization.
- Further research into the mechanism of drug-induced arteritis is warranted.
