Life-Threatening Rupture of an Idiopathic Left Hepatic Artery Pseudoaneurysm Successfully Treated with Endovascular Coil Embolization

Abstract EN

Hepatic artery pseudoaneurysm is a rare condition; they are multifactorial, most of them locating in the extrahepatic vasculature and the mortality associated to its rupture may reach up to 70%.

We report a 77 years old female who was admitted due to headache and uncontrolled hypertension and that on her second hospital day developed sudden hemodynamic instability, abdominal pain, fatigue, skin-mucosa pallor, and anemia.

Abdominal CT scan with contrast showed a left hepatic artery pseudoaneurysm associated with extensive hemoperitoneum.

Patient required emergent hemodynamic stabilization and finally was treated successfully with a superselective endovascular coil embolization.

Our patient represents an atypical case of a spontaneous rupture of an idiopathic hepatic artery pseudoaneurysm.

Hence, the importance of having a high index of clinical suspicion.

Endovascular coil embolization has become the first-line treatment.
