Sphenopalatine Artery Pseudoaneurysm Managed with Endovascular Embolization: A Case Report

Area of Science:

• Vascular Surgery
• Interventional Radiology

Background:

• Sphenopalatine artery (SpA) pseudoaneurysms are a rare cause of severe epistaxis.
• Traditionally, surgical ligation was the primary treatment for SpA pseudoaneurysms.
• Minimally invasive endovascular embolization presents an alternative therapeutic approach.

Purpose of the Study:

• To report a case of epistaxis secondary to a post-traumatic Sphenopalatine artery pseudoaneurysm.
• To illustrate the successful management of this condition using endovascular embolization.

Main Methods:

• A 28-year-old male presented with epistaxis.
• Diagnostic angiography confirmed a Sphenopalatine artery pseudoaneurysm.
• The pseudoaneurysm was treated with endovascular embolization.

Main Results:

• The endovascular embolization procedure was technically successful.
• Epistaxis completely resolved following the embolization.
• The patient was discharged in a stable clinical condition.

Conclusions:

• Endovascular embolization is a safe and effective minimally invasive treatment for Sphenopalatine artery pseudoaneurysms causing epistaxis.
• This technique offers a viable alternative to surgical ligation for managing SpA pseudoaneurysms.
