RESUMEN
@#The present study discussed functional reorganization and alteration in respond to the slow-growing tumour,hemangiopericytoma in the occipital cortex. Visual evoked field (VEF) and auditory evoked field (AEF) usingmagnetoencephalography (MEG) was used to evaluate the source localization and brain activity. Results of VEF sourcelocalization show a typical brain waves. Brain activity of the occipital lobe demonstrate low activation in the ipsilateralto the tumour. However, result shows the activation on the contralateral hemisphere was high and bigger in activationvolume. AEF result shows an identical source localization and both side of the temporal lobe are activated. This resultsuggests that there is a positive plasticity in auditory cortex and slow-growing tumour can induce functional reorganizationand alteration to the brain.
RESUMEN
An 80-year-old man was admitted to our hospital with a diagnosis of distal aortic arch aneurysm. A preoperative chest CT demonstrated a 54 mm in diameter distal aortic arch and coronary angiography revealed stenosis of LAD and the diagonal branch. We planned a thoracic endovascular repair after total arch replacement with a coronary artery bypass graft. A ZTEG-2P-30-200-JP was deployed at the proximal side of the elephant trunk, and a ZTEG-2P-34-152-JP was deployed. About 10 months later, a chest CT demonstrated a 90 mm in diameter distal native aortic arch, and anemia had increased to Hb 7.7 g/dl. A CT and angiography revealed a type II endoleak and so we tried to close the endoleak through a left thoracotomy approach. Twenty-eight months after the TEVAR, the patient had esophageal perforation and stent graft infection. At first, we resected the esophagus and reconstructed it with a gastric tube. Secondly, a descending thoracic aorta replacement was performed. The patient suffered from a cerebral infarction. However, infection was controlled successfully and he was transferred to another hospital for rehabilitation 69 days after the descending aorta replacement.
