Vessel infiltration with microcannula during filler injection: a rare but consequential occurrence

Area of Science:

• Dermatology
• Plastic Surgery
• Vascular Surgery

Background:

• Cosmetic filler injections carry risks, including vascular necrosis from arterial injection.
• Microcannulas are considered safer for filler delivery, reducing vascular occlusion rates.

Observation:

• A case of vessel infiltration was identified *before* microcannula filler injection.
• This observation highlights a critical safety step for cosmetic injectors.

Findings:

• Vessel infiltration can occur even with microcannula use.
• Visual inspection of the introducer needle tip can detect vascular infiltration prior to injection.

Implications:

• This technique may prevent severe complications like vascular occlusion and necrosis.
• Educating injectors on pre-injection needle inspection enhances patient safety in cosmetic procedures.
