Brief Clinical Note

An 80-year-old woman had an aortic valve replacement 1 month before admission and took warfarin for transient atrial fibrillation. She developed a disturbance of consciousness and left hemiplegia. On admission, the right radial artery was slightly palpable. Head MRI images showed a hyper-intense area in the right middle cerebral artery territory. MRA images showed an occlusion of the right M1 distal site and decreased signal at the right internal carotid artery. Contrast CT images of the ascending aorta showed an embolus in the innominate artery. She was diagnosed with an innominate artery saddle embolus and occlusion of the right cerebral artery due to cardiac embolism. She was treated with a heparin infusion and warfarin. She recovered consciousness and from hemiplegia gradually. Recanalization of the innominate artery and right cerebral artery was confirmed. In cases where the radial artery is slightly palpable, it is necessary to consider an innominate artery saddle embolus in addition to aortic dissection.
