2 years post. How do Doctors avoid vascular occlusion?
Vascular occlusion is a rare but serious complication of dermal fillers. The risk is reduced with proper injection technique but the risk is never zero. If a needle was used last time, you can consider having your filler placed with a microcannula to reduce intravascular injection. Always make sure to see a board-certified experienced provider.
Clinical Context
Vascular occlusion occurs when filler enters a blood vessel directly or builds up enough around it to compress it from outside, cutting off blood flow. A sharp needle can pierce a vessel wall, while a blunt-tipped microcannula tends to slide around vessels instead. Injecting slowly, in small amounts, and moving the needle or cannula frequently also helps prevent filler from pooling near a vessel. These techniques lower risk but cannot eliminate it entirely.
