Case Reports
Pseudoaneurysm of the thoracoabdominal aorta caused by a severe migration of an anterior spinal device.
Case report. ⋯ The pseudoaneurysm of the aorta can occur secondary to a migrated anterior spinal fixation device and can be successfully treated by revision anterior surgery with vascular repair and implant removal.

Compared with the cervical spine, little attention has been paid to rheumatoid arthritis (RA)-related lumbar disorders. Only a few articles have described the status of the lumbar spine affected by RA based on plain X-ray films and magnetic resonance imaging (MRI). ⋯ Of 104 patients, 47 (45.2%) exhibited abnormalities on X-ray films and MRI. There were two types of disorders, disc narrowing and disc ballooning. Both the Lansbury index and Ochi's classification reflected the severity of lumbar lesions in RA patients.

Magnetic stimulation (MS), which is used to evaluate motor pathways, is helpful in evaluating cervical spinal cord compression (cervical myelopathy [CM]). Previous studies have shown that the central motor conduction time (CMCT), which is the time taken for the nerve impulses to reach the cervical spinal roots after the stimulation of the motor cortex, is prolonged in CM. However, the duration of motor-evoked potentials (MEPs) in CM has not been studied in detail. ⋯ This study shows that in addition to the CMCT, the duration of MEPs is also useful in evaluating patients with CM using MS.
