Background: Vascular occlusion induced by hyaluronic acid injections is rare, but can lead to severe adverse events, including necrosis, blindness, and cerebral infarction.
Objective: This study aims to explore methods of reducing the risk of complications such as embolism induced by hyaluronic acid injection, and to study the impact of comprehensive systematic treatment on the prognosis of patients with hyaluronic acid embolism.
Methods: The clinical data of three female patients with vascular occlusion due to hyaluronic acid injection was analyzed. Their median age was 26 years, with symptoms presenting 1-6 h postinjection. Hospital stays averaged 6 days. Two patients had ptosis, diplopia, and severe pain after injection of eyebrows. The other, who had a nose enhancement, experienced facial skin color changes and intense pain.
Results: Two patients received comprehensive, systematic treatment based on injectable hyaluronidase. One patient self-discharged after receiving injectable hyaluronidase, antispasmodic, and vasodilator treatment on the night of embolism and returned to the hospital 3 days later with worsening embolism symptoms and received symptomatic treatment again. Two patients who received comprehensive, systematic treatment based on injectable hyaluronidase showed significant improvement, while the patient who did not undergo systematic treatment left scars on the face.
Conclusion: Vascular occlusion caused by hyaluronic acid facial filling is a severe adverse event, and timely, comprehensive, systematic treatment can effectively improve irreversible damage caused by thrombosis, and even cure it.
