Right hepatic artery pseudoaneurysm complicating acute pancreatitis: a case report

Hepatic Artery Pseudoaneurysm in an Infant With Pancreatitis

Hepatic artery pseudoaneurysm (HAP) is an uncommon yet critical complication of acute pancreatitis. This case delves into the unusual scenario of a two-month-old male infant with a familial history of pancreatitis who develops the condition himself. Despite initial treatment, the infant's symptoms worsened, unveiling a pancreatic pseudocyst (PCC) and an atypical pseudoaneurysm stemming from the hepatic artery, a rare complication in acute pancreatitis. The pseudoaneurysm's confirmation through selective angiography and its subsequent management using embolization is highlighted. This report emphasizes the rarity of hepatic artery pseudoaneurysm in the context of acute pancreatitis, stressing the need for thorough imaging to spot arterial involvement. Early identification via selective angiography remains crucial due to the high risks associated with pseudoaneurysm rupture, underscoring the urgency for prompt intervention. In summary, this case spotlights the infrequent occurrence of hepatic artery pseudoaneurysm secondary to acute pancreatitis in an infant. It stresses the importance of swift recognition and intervention to avert potentially life-threatening complications.

Hemorrhage From Left Hepatic Artery Pseudoaneurysm as a Complication of Acute Pancreatitis in a Patient With Fibromuscular Dysplasia

Hepatic artery pseudoaneurysms are a rare complication of pancreatitis, and their rupture and bleeding cause high mortality. We present the case of a 76-year-old woman with fibromuscular dysplasia who developed a new left hepatic artery pseudoaneurysm within a week of her first episode of acute pancreatitis and later suffered an acute pseudoaneurysm bleed successfully treated with transcatheter coil embolization. To the best of our knowledge, this is the first case reported of a patient with fibromuscular dysplasia with pancreatitis-related pseudoaneurysm formation. One must consider pseudoaneurysms and associated bleeding as complications of acute pancreatitis because prompt recognition can lead to timely management.

Left Hepatic Artery Pseudoaneurysm Caused by Acute Pancreatitis

OBJECTIVE

The aim of this work was to report a case of left hepatic artery pseudoaneurysm due to acute pancreatitis following endoscopic papillectomy.

CLINICAL PRESENTATION AND INTERVENTION

A 74-year-old female with an ampullary adenoma underwent papillectomy, which was complicated by acute pancreatitis. Computed tomography showed aneurysmal dilatation of the proximal left hepatic artery. An angiography with coli embolization was performed and was successful. The patient was doing well at the 1-year follow-up.

CONCLUSION

This patient with left hepatic artery pseudoaneurysm following severe acute pancreatitis was successfully treated with coil embolization.
