- Vascular adverse events from hyaluronic acid dermal fillers are typically considered arterial, but venous issues in the lips are less understood.
- Two young women experienced sudden lip swelling and purple discoloration after perioral HA injections, indicating venous drainage obstruction rather than arterial ischemia.
- Both patients received immediate hyaluronidase treatment and monitoring, achieving full recovery without tissue loss within about five days.
- Recent venous mapping studies show variable labial veins and zones of venous accumulation, providing an anatomical basis for this condition.
- It's important to differentiate this from arterial occlusion, angioedema, or hematoma for timely intervention to prevent irreversible damage.
