Guideline for the Management of Hyaluronic Acid Filler-induced Vascular Occlusion.

Vascular occlusions can occur with injection of dermal fillers causing devastating outcomes for the patient. The occurrence, and subsequent management, of these negative outcomes is a source of significant stress to the aesthetic clinician. Complications management is an essential component of clinical practice and professionals must develop competence and confidence in the identification and effective treatment of a vascular occlusion. The relatively rare occurrence of a vascular occlusion mandates that learning must be largely through the study of theory in addition to the sharing of learning experiences within a collaborative clinical community. The delivery of optimal care begins with an understanding of the underlying pathophysiology and the ability to assess and elicit clinical signs. Establishing a clinical diagnosis, targeted therapy can commence in a timely fashion. This paper provides guidance on how to identify and manage a vascular occlusion caused by cross-linked hyaluronic acid. It provides a detailed description of the pathological process of tissue ischemia, and introduces identifiable stages which will help to determine the extent of ischemia and the time frame since ischemic onset. The stages are particularly important as they highlight when wound support may be needed.
