Treatment of Facial Artery Embolization Caused by Polycaprolactone-based Dermal Filler with a Regimen Including 5-Fluorouracil

Polycaprolactone-based fillers are commonly used in plastic surgery to improve facial aging. However, adverse vascular events following these injections have been reported. An arterial embolism is a rare but serious complication associated with injectable filler procedures. We report a case of arterial embolism in a 35-year-old woman who received a polycaprolactone-based dermal filler at the nasal base and was treated with a regimen containing 5-fluorouracil. We discuss the potential causes of the patient's condition and assess the superiority of our method over conventional approaches. Before treatment, ultrasound detected a decreased flow velocity in the patient's right medial canthus artery with distal hypoperfusion, which improved significantly posttreatment. Long-term follow-up revealed near-disappearance of facial scarring. Our treatment effectively addressed facial artery embolism without any reported adverse reactions.
