Background Traumatic facial artery pseudoaneurysms are a rare but significant complication of facial trauma, given the vessel’s small calibre and largely protected location. Prompt identification and management are crucial to prevent growth and potential rupture. Case Report A 25-year-old male presented with a large, full-thickness left cheek laceration following a knife assault. Urgent repair was performed, including microsurgical repair of full-thickness defects in the parotid duct and facial nerve buccal branches. No vascular injury was appreciable on surgical exploration. The patient presented five days later with sudden onset pain and swelling. A CT Face demonstrated a 7mm focus of enhancement at the anterior margin of the parotid. Ultrasound confirmed the presence of a left distal facial artery pseudoaneurysm. Given the proximity of the pseudoaneurysm on microsurgical repairs, a decision for non-operative management was made. Following failed attempts with manual compression and ultrasound-guided thrombin injection, embolization of the pseudoaneurysm was undertaken by interventional radiology via an ultrasound/fluoroscopic guided percutaneous approach. The patient subsequently made an unremarkable recovery with a clinically intact parotid duct and improving paresis of buccal branches. Discussion This case serves to remind surgeons of facial artery pseudoaneurysm as a delayed complication of penetrating facial trauma. Successful management through percutaneous embolization highlights the evolving landscape of treatment options, offering a minimally invasive and selective alternative to traditional surgical approaches and emphasizes the importance of a multidisciplinary approach for optimal patient outcomes.
