 note = {Case 1: A 58-year-old woman with rheumatoid arthritis (RA) suffered from pontine and cerebellar infarctions and underwent three-dimensional computed tomography angiography (3D-CTA) of the vertebral artery (VA) with left-sided rotation of the head. This revealed a destroyed right atlantoaxial (AA) joint and right VA occlusion, which had caused the infarction. No recurrent infarctions have been observed after transarticular screw fixation (Magerl technique) was performed. Case 2: A 68-yearold woman with RA also suffered from pontine and cerebellar infarctions and underwent 3D-CTA of the VA with right-sided rotation of the head. This revealed a destroyed left AA joint and left VA occlusion, which had caused the infarction. No recurrent
infarctions have been observed after posterior fusion between the occiput and 3rd cervical vertebra was performed. In both cases of RA, who had multiple infarctions due to VA occlusion and a temporary thrombus formation, 3D-CTA in a rotated position helped to diagnose arterial occlusion. In addition, posterior fusion of the AA joint was a useful surgical technique., Acta medica Nagasakiensia, 59(3), pp.99-102; 2015},
