Cystic artery embolism after transarterial chemoembolization for hepatocellular carcinoma: A case report and review of the literature.

Abstract

Background: Acute cholecystitis due to unintended cystic artery embolism is an uncommon and mostly self-limiting complication after transarterial chemoembolization procedure for treatment of hepatocellular carcinoma. Usually, conservative management is sufficient for complete recovery of patients who develop this complication. If conservative treatment is ineffective, urgent surgical intervention may be required to prevent the progression of complications.

Case summary: This article reports a rare and serious case of acute cholecystitis complicated by gallbladder necrosis and biliary peritonitis, which was initially treated conservatively but eventually necessitated emergency laparotomy. The patient initially presented with equivocal symptoms of fever and upper abdominal pain and distention, which worsened at the two weeks mark along with emergence of signs of peritonitis. This was managed by emergency laparotomy and cholecystostomy, allowing rapid symptom relief. The patient ultimately discharged and succumbed to advanced liver cancer 11 months after diagnosis.

Conclusion: After cholecystostomy, the patient showed symptom relief and was discharged, surviving 11 months post-stage IIIB liver cancer diagnosis.
