title: Acute mental change and hemiplegia after autologous fat injection.
abstract: Autologous fat injection is a common procedure used for skin augmentation. It is known to be safe and simple, but severe complications have been reported at times. The authors observed a patient with acute large cerebral infarction including the territories of the anterior and middle cerebral arteries and optic nerve infarction developing after autologous fat transplantation. A 32-year-old woman was referred to the emergency room of our hospital due to sudden stupor. Thirty minutes earlier, she was undergoing cosmetic autologous fat injection into the glabella area by a plastic surgeon at a private clinic. The cause was confirmed to be anterior and middle cerebral arteries infarction on brain imaging studies. When a patient presents abrupt mental change, hemiplegia, ocular pain, or blindness after autologous fat particle injection, physicians must consider cerebral infarction and combined retinal artery occlusion.
