factor for mortality in acutely ill patients. 16 , 30 , 36 A previous study revealed that AKI was a relatively common feature in patients with severe traumatic brain injury, and decreased renal function may be associated with worse outcomes. 19 However, little is known about the association between preoperative serum albumin level and postoperative AKI in patients undergoing brain tumor surgery. Thus, the aim of our study was to investigate the incidence of AKI and the risk factors for AKI based on KDIGO criteria in patients undergoing brain tumor surgery

, disturbance of this association fiber tract is believed to be a cause of speech disturbances, including conduction aphasia. 5 , 6 , 8 , 9 , 13 , 16 , 24 , 26 However, the correlation between fiber tracts and language functions has not been evaluated dynamically in humans in vivo with visualizing modalities such as DTI tractography. In the present study, which was conducted in patients undergoing brain tumor surgery, we evaluated whether increased postoperative visualization of the arcuate fasciculus in the dominant hemisphere correlates with improvement of postoperative

A high incidence of postoperative thromboembolic events has been reported in patients undergoing brain tumor surgery and is a leading cause of mortality when pulmonary embolism develops. 4, 6, 7, 10 The risk for thrombosis has been reported to be different among the various types of brain tumors; it is highest for patients with meningioma (72%), followed by patients with glioma (60%), and markedly lower for patients with brain metastases (20%). 6 Despite the severity of clinical consequences the literature holds rather little information about the

to hemorrhage. It has convincingly been demonstrated that a suppression of the tissue factor–dependent coagulation pathway contributes to spontaneous intratumoral bleeding in GBMs. 19 In addition, the interindividual expression of vascular endothelial growth factor subtypes possibly affects tumoral hemorrhage in this setting. Cheng and colleagues 1 demonstrated that overexpression of certain vascular endothelial growth factor subtypes in GBMs was associated with spontaneous hemorrhage in a mouse model. Another interesting phenomenon in brain tumor surgery is the

I dentification of neural tracts is indispensable for the protection of functions during brain tumor surgery. Among intrinsic brain tumors, gliomas are often not well-demarcated and are hard to distinguish from normal structures. Early identification of neural tracts gives good spatial orientation for surgeons and contributes to the avoidance of neural tract injury. Fiber tracking with diffusion tensor imaging (DTI) has been used to draw the pyramidal tract. However, the lines drawn in tractography do not necessarily show the actual pyramidal tract in terms of

I mprovements in the surgical management of primary and metastatic brain tumors have resulted in greater extent of resection, less postoperative morbidity, and longer overall survival. Consequently, maximal safe resection is the basic tenet of brain tumor surgery. Advanced surgical techniques such as electrophysiological mapping, intraoperative MRI, and fluorescence-guided surgery have been developed to improve safety and extent of tumor resection. Despite these surgical advances, studies analyzing patterns of failure after brain tumor surgery indicate

many patients develop PILRT after brain-tumor surgery? 2) which patients develop PILRT? 3) when does PILRT start in the postoperative course? Clinical Material and Methods This retrospective investigation includes 289 consecutive patients who were operated on for intracranial tumors ( Table 2 ). They are subdivided into two groups. Group A included 186 patients operated on up to November 30, 1984. The clinical course of these patients was analyzed to identify relevant risk factors. Twenty-two of the patients had pituitary adenomas and were operated on

S ince 2005, Boston Children’s Hospital’s Department of Neurosurgery has employed intraoperative MRI (ioMRI) using a 1.5T mobile magnet during brain tumor surgery (IMRIS). One of the goals of this technology is to guide and demonstrate the extent of tumor resection while the craniotomy flap is still open in the hope of avoiding a subsequent return to the operating room to remove resectable residual tumor detected on a postoperative scan. 5 , 8 , 9 , 19 Demonstrating the utility of this technology is an important issue, as there is a significant expense to

for each class of neurosurgical procedures, as Spetzler and Martin did in 1986 for arteriovenous cerebral malformations. 36 Hence, we thought that focusing on brain tumors would render a wide enough, representative, and fairly homogeneous sample. This study was therefore designed to identify the impact of some important preoperative factors on the outcomes of brain tumor surgery, with the aim of building a new, easy, and practical grading scale capable of predicting the risk of clinical worsening after performing a craniotomy or endoscopic endonasal approach for

function with psychiatric symptoms in patients with psychiatric and somatic conditions, there are no studies evaluating the association of thyroid axis function with depression and anxiety in brain tumor patients. 4 , 12 The identification of depression and anxiety biomarkers could potentially improve risk stratification and contribute to the improved care and survival of these patients. Therefore, the aim of the present report was to evaluate, in patients undergoing brain tumor surgery, the prevalence of perioperative low T3 syndrome and the direct association of
