Resumo

- Facial injections with different dermal fillers have become increasingly common.
- The explosion in the use of these injectable materials has brought a concomitant rise in the incidence of complications.
- Vascular comprise is the most concerning complication of all, caused either by intravascular injection (arterial or venous), external compression (mostly of the veins), thrombosis or embolization. *The incidence of vascular occlusion following soft tissue injection may be as high as 3 in 1000.
- As a result, blood flow may be interrupted leading to ischemia, necrosis or ulcerations to embolizations with lung thromboembolism, blindness and cerebral vascular injuries.
