Rupture of Hepatocellular Carcinoma after Transarterial Chemoembolization followed by Massive Gastric Bleeding

摘要

Introduction. Transarterial chemoembolization (TACE) is the first-line therapy for patient with unresectable hepatocellular carcinoma (HCC). Although TACE is a generally safe procedure, major complications can be occurred. We describe a patient with rupture of HCC after TACE followed by gastric bleeding. Case Presentation. An 81-year-old man presented with worsening epigastric pain. He had been diagnosed with multiple HCC with nonalcoholic steatohepatitis and underwent TACE 19 days previously. A contrast enhanced computed tomography (CT) scan of the abdomen showed rupture of an HCC. He was treated nonoperatively and discharged on hospital day 18. Five weeks after TACE, he was emergently admitted with massive hematochezia and shock. A contrast enhanced CT scan demonstrated extrinsic gastric compression by an HCC lesion with extravasation of contrast into the stomach. Emergent upper gastrointestinal endoscopy showed a bleeding gastric ulcer with extraluminal compression which was successfully controlled by hypertonic saline-epinephrine injection. Due to tumor progression, he was discharged for palliative care and died six weeks after TACE. Conclusion. Rupture of HCC is a life-threatening complication after TACE with mortality rates up to 50%. After treatment of a ruptured HCC, extragastric compression and bleeding can occur due to direct compression by a primary lesion or intraperitoneal dissemination.
