Some reports are suggesting the efficacy of continuous irrigation therapy for brain abscesses, but way how to irrigate and perfusion abscesses cerebral spinal fluid has not yet been established. Here, we present case successfully treated by severe bacterial abscess, meningitis, encephalitis. A 62-year-old man presented our hospital with a chief complaint headache vomiting. Magnetic resonance imaging revealed an encapsulated lesion peripheral contrast in left cerebellar hemisphere, showed...
BACKGROUND Microsurgical clipping with extradural anterior clinoidectomy (EDAC) for paraclinoid aneurysm is an established technique good angiographic outcomes, although postoperative worsening of visual acuity remains a concern. Multiple reports show deteriorating after clipping, yet the cause unclear. OBJECTIVE To analyze results asymptomatic surgeries treated EDACs, specifically focusing on microanatomy structure dissection. This determined causes delayed impairment and microsurgical...
Background: The occipital artery (OA) is an important donor for posterior fossa revascularization. Harvesting the OA difficult in comparison to superficial temporal because runs between suboccipital muscles. Anatomical knowledge of muscles and essential harvesting during elevation splenius capitis muscle (SPL) reconstruction inferior cerebellar artery. We analyzed running pattern its anatomic variations using preoperative intraoperative findings. Methods: From April 2012 March 2018, we...
Abstract Despite technological advances in endovascular therapy, surgical clipping of paraclinoid aneurysms remains an indispensable treatment option and has acceptable profile risk. Intraoperative monitoring motor somatosensory evoked potentials proven to be effective tool predicting preventing postoperative deficits during aneurysm clipping. 1,2 We describe the case a 61-yr-old Japanese woman with history hypertension smoking. During follow-up for bilateral ophthalmic segment internal...
Several treatments for traumatic facial paralysis have been reported, but the role of surgery is still controversial.A 57-year-old man was admitted to our hospital with head trauma due a fall injury. A total body computed tomography (CT) scan showed left frontal acute epidural hematoma associated optic canal and petrous bone fractures disappearance light reflex. Hematoma removal nerve decompression were performed immediately. The initial treatment successful complete recovery consciousness...
Giant thrombosed posterior circulation aneurysms are rare lesions with a natural history associated high morbidity and mortality.1-6 The treatment has risk either microsurgical or endovascular (ET). While ET allows easier access but recurrence rate, more difficult provides durable lasting treatment.7-13 A 47-year-old woman presented left hemiparesis from right giant basilar artery-superior cerebellar artery (BA-SCA) aneurysm buried in the brainstem surrounding edema. Owing to of perforator...
Hemangioblastomas are hypervascular lesions and hence their surgical management is challenging. In particular, if complete resection to be attained, all feeding draining vessels must occluded. Although most intramedullary spinal cord tumors treated utilizing a posterior approach, we describe an anterior strategy for of cervical hemangioblastoma.A 36-year-old female with hemangioblastoma located in the presented long-standing history motor weakness right upper extremity. Magnetic resonance...
Abstract A 59-year-old female with recurrent Anterior Choroidal Artery (AchA) aneurysm was elected for surgery at our institution through a standard pterional approach. Two thin perforating branches were found to origin from the dome of during operation, and therefore complete clipping preserving these not feasible. These temporarily occluded under motor-evoked potential (MEP) monitoring. The MEPs remained stable 10 min temporary clipping, we concluded that could be sacrificed, neck...

Diagnosing Multiple Sclerosis (MS) and other demyelinating diseases such as neuromyelitis optica (NMO) is not always easy clinically the neuropathology of two remains mystery. Recent advances in proteomic technology search biomarker or signature that accurately identifies clinical syndrome would allow for improved diagnosis disease monitoring.
Introduction: To evaluate the clinical outcomes and factors affecting prognosis of giant aneurysms to better establish role microsurgery with bypass in its management.
