Hepatic artery pseudoaneurysm caused by chronic pancreatitis: Case report and literature review.

Rationale: Visceral artery pseudoaneurysm is a rare complication of chronic pancreatitis (CP), all pancreatic or peripancreatic arteries have been reported to be involved, while hepatic artery is less common.
Patient Concerns: This case report illustrated a 42-year-old man with CP who developed right hepatic artery pseudoaneurysm (HAP), and finally he was treated with intravascular embolization.
Diagnoses: The patient suffered from HAP due to acute attack of CP.
Interventions: The pseudoaneurysm located in a fine branch of right hepatic artery was embolized.
Outcomes: The HAP of the patient was cured. He had no recurrent bloody stool or abdominal pain. The symptoms gradually relieved.
Conclusion: Herein, we report a patient with CP who developed right HAP causing infected hematoma, gastrointestinal bleeding, and obstructive jaundice, and a literature review is also presented. HAP caused by CP is a rare disease in the clinic, but rupture of pseudoaneurysm is fatal. Careful evaluation, early detection, and prompt treatment should be performed when the patient is admitted and followed up.
