Abstract
Facial injections with cosmetic fillers can lead to local artery occlusion. The bilateral nasolabial folds of a 39-year-old woman were injected with hyaluronic acid at another hospital. After the righthand injection, the patient immediately felt pain that ran from the right nasolabial fold to the nasal alar. The injecting doctor suspected embolism due to intravascular misinjection and immediately injected hyaluronidase and vasodilator subcutaneously and intravenously, respectively. Five days later, the patient presented at our hospital with extensive endovascular embolization-related signs: along with some oral mucosa, the skin of the right nasolabial fold, right nasal alar, and right mouth corner exhibited necrosis. We diagnosed secondary peripheral embolus, and we used the treatment, namely, subcutaneously flooding/immersing the embolization site in the peripheral blood vessels with 2000 units of hyaluronidase.
