Journal of Neurosurgery, Ahead of Print. OBJECTIVE Coiling of wide-necked and complex bifurcation aneurysms frequently requires implantation of double stents in various configurations. T-stent–assisted coiling involves the nonoverlapping implantation of 2 stents to protect the daughter vessels of bifurcation and is followed by coiling of the aneurysm.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Fragmentation of care has been recognized as a major contributor to 30-day readmissions after surgical procedures. The authors investigated the association of evaluation in the hospital where the original procedure was performed with the rate of 30-day readmissions for patients presenting to the emergency department (ED) after craniotomy for primary brain tumor resection.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Reperfusion therapy with intravenous recombinant tissue plasminogen activator (rtPA) is the standard of care for acute ischemic stroke. However, hemorrhagic complications can result. Intravenous infusion of mesenchymal stem cells (MSCs) reduces stroke volume and improves behavioral function in experimental stroke models.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The aim of the present study was to evaluate the usefulness of navigated transcranial magnetic stimulation (nTMS) as a prognostic predictor for upper-extremity motor functional recovery from postsurgical neurological deficits. METHODS Preoperative and postoperative nTMS studies were prospectively applied in 14 patients (mean age 39 ± 12 years) who had intraparenchymal brain neoplasms located within or adjacent to the motor eloquent area in the cerebral hemisphere.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE To study peritumoral brain edema (PTBE), it is necessary to create a model that accurately simulates vasogenic brain edema (VBE) without introducing a complicated tumor environment. PTBE associated with brain tumors is predominantly a result of vascular endothelial growth factor (VEGF) secreted by brain tumors, and VEGF infusion alone can lead to histological blood-brain barrier (BBB) breakdown in the absence of tumor.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Advanced age is known to be associated with a poor prognosis after surgical clipping of unruptured intracranial aneurysms (UIAs). Keyhole clipping techniques have been introduced for less invasive treatment of UIAs. In this study, the authors compared the complications and clinical and radiological outcomes after keyhole clipping between nonfrail elderly patients (≥ 70 years) and nonelderly patients.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The mechanism by which greater institutional case volume translates into improved outcomes after surgical clipping of unruptured intracranial aneurysms (UIAs) is not well established. The authors thus aimed to assess the effect of case volume on the rate of various types of complications after clipping of UIAs.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE In the treatment of glioblastoma, residual tumor burden is the only prognostic factor that can be actively influenced by therapy. Therefore, an accurate, reproducible, and objective measurement of residual tumor burden is necessary. This study aimed to evaluate the use of a fully automatic segmentation method—brain tumor image analysis (BraTumIA)—for estimating the extent of resection (EOR) and residual tumor volume (RTV) of contrast-enhancing tumor after surgery.… Read More...
