Transarterial catheter embolisation for an unusual cause of upper gastrointestinal haemorrhage

An unusual case of acute cholecystitis complicated by haemobilia and Mirizzi-like obstruction: a case report and review of literature

Introduction

Cystic artery pseudoaneurysm rupture presents a rare yet potentially fatal aetiology for upper gastrointestinal (GI) bleed. While uncommon, its incidence has been rising with increased hepatobiliary surgical interventions, predominantly attributed to iatrogenic injury and rarely secondary to acute cholecystitis. Clinical manifestations typically include epigastric pain, upper GI haemorrhage, and obstructive jaundice. Due to its rarity, it is often excluded from initial differential diagnoses.

Case report

This is an unusual case of a 54-year-old male who presented with acute cholecystitis complicated by haemobilia and Mirizzi-like obstruction, in the setting of cystic artery pseudoaneurysm rupture. Initially, urgent transcatheter angiographic embolization of the cystic artery was performed to achieve hemodynamic stability. However, a triphasic computed tomography (CT) scan revealed the first attempt was unsuccessful, necessitating a second embolization. Subsequent imaging confirmed satisfactory embolization; however, a small area of liver necrosis was observed adjacent to the gallbladder. The patient was stable at discharge from the hospital and had an uncomplicated interval cholecystectomy.

Discussion

This case highlights the complexity and challenges associated with diagnosing and managing cystic artery pseudoaneurysm rupture. Diagnosis often relies on arterial phase contrast-enhanced CT scan. While no guideline currently exist, management typically involves achieving hemodynamic stability through Transcatheter angiographic embolization, followed by interval cholecystectomy.

Conclusion

Early recognition and intervention are crucial in managing cystic artery pseudoaneurysm rupture to prevent life-threatening haemorrhagic shock. Clinicians need to consider this rare condition in patients with upper GI bleeding and abnormal liver function tests.

Acute hemobilia from a pseudoaneurysm of the cystic artery arising from the left hepatic artery: Case report and literature review

INTRODUCTION

Hemobilia represents only 6% of all causes of upper gastrointestinal bleeding.

PRESENTATION OF CASE

We report a rare case of a bleeding pseudoaneurysm of the cystic artery, due to a re-activation of a chronic cholecystitis, which arose with a mixed symptomatology: jaundices and hematemesis.

DISCUSSION

The rarity of our patient is increased for some vascular anatomic variations detected by Computed Tomography that influenced the management of the disease. Our patient was treated by endovascular embolization of the pseudoaneurysm and subsequent cholecystectomy.

CONCLUSION

About pseudoaneurysm of the cystic artery only few cases have been already reported and to date there are no guidelines for its management. We describe both diagnostic features and therapeutic strategies in comparison to the most recent literature.
