Management strategies for vascular complications in hyaluronic acid filler injections: A case series analysis

Abstract Background As hyaluronic acid (HA) filler injections have become increasingly popular in the esthetic field, so have their side effects. Vascular complications, which can lead to skin necrosis or permanent scarring, are a particularly dangerous complication and occur when the filler is injected directly into a blood vessel or when an adjacent blood vessel is compressed by the filler material. Objective To assess the clinical prognosis based on post‐procedural management and clinical findings of HA filler vascular complications. Methods Herein, we present a case series of vascular complications due to HA filler and evaluate their clinical prognosis based on post‐procedural management and clinical findings. Clinical assessments were performed using Doppler ultrasound, thermography, and laboratory tests. Results Factors including white blood cell count, the time of treatment initiation, and time of hyaluronidase injection influenced the clinical outcomes. Early recognition and prompt hyaluronidase injection proved crucial in preventing further damage and improving prognosis. Conclusion This case series highlights the importance of early detection and appropriate management of HA filler complications. Physicians should be aware of the potential risks associated with fillers and promptly address any adverse effects to achieve optimal clinical outcomes. Further studies are warranted to confirm these findings and refine treatment strategies for the HA filler complications.
