Filler injections with needles or cannulas are associated with a very low risk for intravascular occlusion events, researchers reported a study published in JAMA Dermatology.
The retrospective cohort study sought to determine whether filler-associated vascular occlusion events of the face occur more frequently with injections using needles than with microcannulas, when performed by board-certified dermatologists. Data relating to patients undergoing filler procedures in the dermatologists’ practices were obtained from August 2018 to August 2019.
