Cardiac Arrest Triggered by Ruptured Aberrant Left Hepatic Artery Aneurysm and Subsequent Management.

Hepatic artery aneurysms (HAAs) are a rare type of splanchnic artery aneurysm. Our understanding is limited given the rarity of incidence. Rupture on presentation has a high mortality rate. We report the case of a 71-year-old woman who presented with a ruptured aberrant left HAA and subsequent cardiac arrest. She had risk factors of hypertension and was a long-term smoker. Post imaging-guided diagnosis and emergent multi-disciplinary discussion with the interventional radiology team, she underwent surgical resection of the aneurysm. Her recovery was unremarkable with gradual resolution of hepatic dysfunction and no residual post-arrest deficits. This case provides insight into the challenges of HAA anatomy and decision-making regarding surgical versus endovascular management and techniques.
