Preventing and Treating Vascular Complications of Cosmetic Filler Injections

Conclusions

• Filler injections in the face can cause serious vascular complications, including skin necrosis, blindness, stroke, and death.
• The highest-risk areas are the central face and other facial regions with important arterial anastomoses, especially the forehead, glabella, nose, nasolabial fold, lips, temple, and periorbital area.
• Anatomy is variable, so no facial injection site is completely risk-free and standard textbook vessel maps cannot be relied on alone.
• Complications are more likely with forceful, fast, high-volume, or poorly placed injections, especially in superficial planes or with small-gauge tools.
• The safest preventive approach is to inject slowly, gently, with low volume, at the correct depth, using appropriate technique and anatomical caution.
• Aspirating before injection may help detect intravascular placement, though it is not a guarantee of safety.
• Previous facial surgery can alter vascular anatomy and increase unpredictability and risk.
• If abrupt eye pain, vision change, blanching, reticulated discoloration, or other vascular compromise occurs, the injection should stop immediately and the emergency response should begin at once.
• Rapid treatment may occasionally salvage vision, but the presentation emphasizes that prevention is far more important than rescue.
• Preparedness requires having hyaluronidase, vasodilators, pressure-lowering eye medications, oxygen, corticosteroids, and a plan for urgent ophthalmology and neurology consultation available in the office.
