BACKGROUND Subarachnoid hemorrhage (SAH) has a global incidence of 9/100,000. In low-resource settings, where neurosurgical capacity is diminished through fewer human and technological resources, neurosurgeons may not be prepared to operate on aneurysm cases in emergent situations. We report a patient presented with aneurysmal SAH in rural Iran, creating(More)
BACKGROUND Complex aneurysms of the anterior cerebral artery (ACA) may require a bypass procedure as part of their surgical management. Most current bypass paradigms recommend technically demanding side-to-side anastomosis of pericallosal arteries or use of interposition grafts, which involve longer ischemia times. The purpose of this study is to assess the(More)
OBJECTIVE The anterior temporal artery (ATA) supplies an area of the brain that, if sacrificed, does not cause a noticeable loss of function. Therefore, the ATA may be used as a donor in intracranial-intracranial (IC-IC) bypass procedures. The capacities of the ATA as a donor have not been studied previously. In this study, the authors assessed the(More)
OBJECTIVE We describe the setup and use of different 3-dimensional (3-D) recording modalities (macroscopic, endoscopic, and microsurgical) in our laboratory and operating room and discuss their implications in neurosurgical research and didactics. We also highlight the utility of 3-D images in providing depth perception and discernment of structures(More)
BACKGROUND The anterior temporal artery (ATA) is an appealing donor artery for intracranial-intracranial bypass procedures. However, its identification may be difficult. Current literature lacks useful landmarks to help identify the ATA at the surface of the sylvian fissure. The objective of this study was to define the topographic anatomy of the cortical(More)
BACKGROUND The expanded endoscopic endonasal ("far medial") approach to the inferior clivus provides a unique surgical corridor to the ventral surface of the pontomedullary and cervicomedullary junctions. However, exposing neoplasms involving the jugular foramen (JF) through this approach requires extensive nasopharyngeal resection and lateral dissection(More)
BACKGROUND Identification and protection of the cochlea during anterior petrosectomy is key to prevent hearing loss. Currently, there is no optimal method to infer the position of the cochlea in relation to the Kawase quadrangle, therefore damage to the cochlea during anterior petrosectomy remains a substantial risk. OBJECTIVES To identify and define(More)
Leukotriene B4 (LTB4) is the major 5-lipoxgenase product released during early experimental glomerulonephritis. To test its functional relevance, its actions in the normal rat kidney and its influence on renal function in the heterologous phase of mild nephrotoxic serum-induced glomerular injury were examined. Intrarenal administration of leukotriene B4(More)
