Cerebral air embolism (CAE) occurs in various clinical situations such as surgery, angiography, and hemodialysis; most are iatrogenic. Here we report the case of a 57-year-old man who developed CAE immediately after air-powder abrasive treatment, which is commonly used in dentistry. The patient underwent air-powder abrasive treatment for peri-implantitis, and immediately after the treatment, cardiac arrest occurred and cardio- pulmonary resuscitation was performed. After resuscitation, brain computed tomography performed in the emergency room showed scattered dark density presumed to be air. The day after admission, the patient showed right hemiplegia and a multifocal cerebral infarction was observed on brain magnetic resonance imaging. Therefore, CAE was strongly suspected. After hyperbaric oxygen treatment (HBOT), which started 4 days after the incident, the patient regained consciousness and showed improvement in cognitive impairment, and only grade 4 muscle weakness was observed in the right lower extremity on the manual muscle test. This case highlights the importance of considering CAE as a possible cause of neurological symptoms occurring during clinical procedures involving air, and adds to the accumulation of evidence of therapeutic effects of delayed HBOT.
