BACKGROUND: Vascular occlusion (VO) is a rare but serious complication of dermal filler injection. Current management protocols are derived primarily from hyaluronic acid fillers and rely on enzymatic degradation with hyaluronidase. Ellansé (PCL-CMC) is a poly-ε-caprolactone (PCL)-based filler composed of PCL microspheres suspended in a carboxymethyl cellulose (CMC) gel carrier, neither of which is a substrate for hyaluronidase; a product-specific management approach is therefore required.
OBJECTIVES: To develop expert consensus recommendations for the recognition and management of VO associated with PCL-CMC.
METHODS: A targeted literature review (PubMed, January 2009-August 2025), in vitro rheometry and flow testing, and a three-round modified Delphi consensus process involving seven international experts were used to develop a staged management algorithm.
RESULTS: At 1:5 dilution, PCL-CMC viscosity decreased approximately 80-fold to near-aqueous levels; hyaluronidase solution conferred no additional benefit over saline alone. A full consensus or a consensus based on majority of the experts consensus (≥80%) was achieved on the majority of statements, including CMC-mediated obstruction as the primary mechanism, high-volume saline flushing with mechanical dispersion as first-line therapy, and retention of hyaluronidase in a supportive role.
CONCLUSIONS: This consensus-derived algorithm prioritizes reperfusion through dilution and mechanical dispersion rather than enzymatic degradation. Prospective clinical validation is required.
