Although hyperglycemia is a serious complication of subarachnoid hemorrhage, its pathophysiologic mechanism based on neural circuitry has not been known. ⋯ There is an important linear relationship among the blood glucose levels, DND of the IC, and nodose ganglia and degenerated surface areas of IL following experimentally induced sylvian SAH.

A thorough understanding of the orbit, structures within it, and complex spatial relationships among these structures bears relevance in a variety of neurosurgical cases. We describe the 3-dimensional surgical anatomy of the orbit and fragile and complex network of neurovascular architectures, flanked by a series of muscular and glandular structures, found within the orbital dura.

Over the last decade, surgical technology in planning, mapping, optics, robotics, devices, and minimally invasive techniques has changed the face of modern neurosurgery. We explore the current advances in clinical technology across all neurosurgical subspecialties, examine how clinical practice is being shaped by this technology, and suggest what the operating room of tomorrow may look like.

Surgical treatment of giant pituitary adenomas is sometimes challenging. We present our surgical series of giant nonfunctioning adenomas to shed light on the limitations of effective and safe tumor resection. ⋯ Irrespective of the surgical approach, massive intracranial extension, an irregular configuration, and marked CS invasion are inherent factors that independently limit effective resection. These high-risk tumors require an individualized therapeutic strategy.

Dilatation of the microvascular diameter is recognized in moyamoya disease and referred to as microvascularization. The purpose of this study was to characterize the cortical microvascularization in moyamoya disease using imaging analysis, and to explore the developmental mechanism of the collateral network around the cortical surface. ⋯ In the patients with moyamoya disease, the cortical microvascularization exhibited increased Db and dilatation of the pial arteries. In moyamoya disease, cortical microvascularization is associated with clinical and radiologic factors. This microvascularization might be a compensatory mechanism in the ischemic condition in moyamoya disease.
