A 59-year-old man was admitted to our hospital for hematemesis. A hematoma was found in the posterior wall of the stomach, but the source of bleeding was not identified. One month later, contrast-enhanced computed tomography revealed a pseudoaneurysm in the short gastric artery. Embolization of the pseudoaneurysm was difficult due to vessel tortuosity. Usage of a distal access catheter improved catheter stability and enabled successful embolization. We consider a distal access catheter to be useful for embolization of an aneurysm beyond a tortuous artery.
