%X BACKGROUND: Hyaluronic acid (HA) filler-induced vascular embolism that threatens skin integrity is an urgent situation. There is increasing evidence that percutaneous intra-arterial hyaluronidase injection is an effective therapeutic technique for it. However, until now, there is a lack of a unifying protocol about the technique.
OBJECTIVE: This study aims to provide a conclusion of percutaneous intra-arterial hyaluronidase injection along with adjunctive measures on the treatment of occlusions precipitated by HA-based filler and develop a stepwise treatment protocol.
METHODS: We searched PubMed for peer-reviewed studies, consensus statements, case series, and case reports using a variety of keywords.
RESULTS: High-dose, pulsed hyaluronidase is the mainstay for the treatment of HA filler-induced embolism, but percutaneous intra-arterial hyaluronidase injection is a more effective technique. Until now, hyaluronidase is injected into three arteries percutaneously, including facial artery, supratrochlear artery, and superficial temporal artery. Furthermore, the adjunctive measures that may optimize clearance of an occlusion and/or skin barrier repair such as the use of image guidance and CGF should be considered.
CONCLUSIONS: Vascular occlusions that threaten skin integrity are an urgent matter which requires accurate diagnosis and effective intervention. Percutaneous intra-arterial hyaluronidase injection along with adjunctive measures performed in a stepwise manner is key to an optimal outcome.
