Recent studies have demonstrated that cytokines play an important role in the pathogenesis of intracranial aneurysms (IAs). Interleukin-6 (IL-6) is an important proinflammatory cytokine. In our study, we investigated the association of genetic variants within the gene encoding interleukin-6-572G/C (IL-6-572G/C) with IAs in the Cantonese population. The(More)
Gliosarcoma is relatively rare brain tumor of glial and sarcomatous origin. The occurrence of this highly malignant brain tumor in the vicinity of the clipped aneurysm has not been reported in the literature. The authors report a case of 37-year-old man who developed sudden onset severe headache. Angiogram displayed a saccular aneurysm located on the(More)
OBJECTIVE To evaluate the feasibility, efficacy and safety of a new method for distant injection of Onyx for treatment of intracranial arteriovenous malformations (AVMs). METHODS The clinical data of 26 patients with AVMs receiving distant injection of Onyx using the new method were retrospectively analyzed. Onyx was injected by the surgeon in the control(More)
BACKGROUND The anterior communicating artery (ACoA) is one of the most frequent sites for cerebral aneurysm. The peculiar directions of projection of aneurysms offer great challenges to clinical treatment. OBJETIVES To establish the relationship between morphology of A-1 segment of anterior cerebral artery (ACA) and aneurismal projection. METHODS(More)
OBJECTIVE To investigate the expression of matrix metalloproteinase-9 (MMP-9) in the arachnoid membrane around posterior communicating artery aneurysms. METHODS Twelve patients with posterior communicating artery aneurysms undergoing surgical intervention in our hospital between November, 2010 and November, 2011 were enrolled as the case group along with(More)
Temozolomide (TMZ) is the main chemotherapeutic drug utilized for the treatment of glioblastoma multiforme (GMB), however, drug resistance often leads to tumor recurrence and poor outcomes. GMB cell lines were treated with TMZ for up to two weeks and then subjected to proteomics analysis to identify the underlying molecular pathology that is associated with(More)
The external wrapping of intracranial aneurysm is the definitive treatment of choice for surgical clipping or endovascular occlusion, yet there may exist considerable difficulties and risks because so far neither ideal wrapping techniques nor ideal wrapping materials have been obtained. An encapsulated aneurysm clip with biomembrane graft across the vessels(More)
BACKGROUND It has been reported that various types of axonal injury of hypothalamo-neurohypophyseal tract can result in degeneration of the magnocellular neurons (MCNs) in hypothalamus and development of central diabetes insipidus (CDI). However, the mechanism of the degeneration and death of MCNs after hypophysectomy in vivo is still unclear. This present(More)
OBJECTIVE To explore the imaging features, diagnosis and treatment strategies of intracranial lageniform aneurysms. METHODS The clinical characteristics and therapeutic outcomes of 6 patients with intracranial lageniform aneurysms were retrospectively analyzed. RESULTS All the 6 aneurysms, including 5 anterior communicating artery aneurysms and 1 middle(More)
Displacement of distal ventriculo-atrial (VA) shunt is not uncommon. However, misplacement of the distal catheter of VA shunt in the internal jugular vein is a possibility, especially when conducted without intraoperative monitoring. We describe a patient in whom a VA shunt was performed due to failure of ventriculo-peritoneal shunt and the distal catheter(More)
