To study the factors responsible for failure of hemispherotomy and outcomes of revision surgery. The effect of the surgeon's learning curve on failures was also analyzed. ⋯ Surgical revision is more common in hemimegalencephaly and in the early days of a surgical program. Affirmative neuroimaging improves the outcomes of subsequent revision surgery.

A scientific publication is a mirror that defines the image of a researcher in his academic and professional world. Neurosurgery and Journal of Neurosurgery (JNS) are the 2 most reputed journals in the neurosurgical community. ⋯ Multiauthor and multi-institutional studies ensure greater expertise and thus better impact. Limited by the sample size, only a weak correlation was found with increased title count and retrospective studies with citations, although their increase is an indicator of future trends. Both journals have shown a steady increase in their impact and quality of publications. To the best of our knowledge, our study is the first to examine the correlation of various factors and citations in neurosurgery in the post-2000 era.

Few studies have examined associations between vascular compression and postoperative pain relief in patients undergoing microvascular decompression (MVD) for treatment of medically refractory type 1 trigeminal neuralgia (TN). The authors sought to examine for associations between vascular compression and postoperative pain relief to determine the utility of preoperative magnetic resonance imaging (MRI) in surgical decision-making for TN. ⋯ The findings of lower sensitivity and poor interrater reliability of MRI, as well as a lack of association between compressive vessel and postoperative pain relief reported in this study, suggest the decision to pursue MVD for TN should be based more heavily on classic symptomatic presentation over preoperative evidence of vascular compression.

Application of Advanced Technology During Resection of Posterior Fossa AVMs: Two Sister Cases.
Various advanced imaging and intraoperative technologies can be used during resection of posterior fossa arteriovenous malformations (AVMs) in a hybrid neurovascular operating room. These technologies include transradial intraoperative angiography with post-processing of angiographic data for navigation (in combination with stereotactic magnetic resonance imaging) (Figure 1). Advanced semiautomated processing allows magnetic resonance imaging, computed tomography angiography, and angiography fusion for enhanced localization of the AVM. ⋯ While these technologies are potentially useful in certain circumstances, they may not be necessary in the case of relatively straightforward vascular lesions. Keeping this in mind is of particular importance, as the use of these technologies may require extended time with the patient under anesthesia. These sister cases of cerebellar AVMs illustrate the spectrum of the advanced technologies that are potentially available to surgeons during posterior fossa AVM resection (Video 1).
