Review Historical Article
Assessing the relevancy of "citation classics" in neurosurgery. Part II: Foundational papers in neurosurgery.
The second part of this study reanalyzes Ponce and Lozano's (2010) list of classics to create a new list of "foundational" articles in neurosurgery. Ponce and Lozano (2010) previously published a list of 106 neurosurgery classics, as defined by Garfield and his 400 citation criterion. ⋯ By assessing citation counts as a function of time, we are able to differentiate classic neurosurgical studies that are critical to modern-day practice from those that are primarily of historic interest. Given the exponential growth of literature in our field, analyses such as these will become increasingly important to both trainees and senior neurosurgeons who strive to educate themselves on the data that drive modern-day clinical decision making.

Review
Metabolic in vivo Visualization of Pituitary Adenomas: a Systematic Review of Imaging Modalities.
Pituitary adenomas (PAs) are the most common intrasellar mass. Functional PAs constitute most of pituitary tumors and can produce symptoms related to hormonal overproduction. Timely and accurate detection is therefore of vital importance to prevent potentially irreversible sequelae. Magnetic resonance imaging is the gold standard for detecting PAs, but is limited by poor sensitivity for microadenomas and an inability to differentiate scar tissue from tumor residual or predict treatment response. Several new modalities that detect PAs have been proposed. ⋯ PET and MRS appear to have the strongest predictive value in detecting PAs. MRS has the advantage of low cost, but the literature is lacking in specific studies of the pituitary. Due to high recurrence rates of functional PAs and low sensitivity of existing diagnostic workups, further investigation of metabolic imaging is necessary.

Case Reports Comparative Study
Overlapped Stenting Combined with Coiling for Blood Blister-like Aneurysms: Comparison of Low-profile Visualized Intraluminal Support (LVIS) Stent and Non-LVIS Stent.
To evaluate the safety and efficacy of overlapped stenting for blood blister-like aneurysms (BBAs) and to compare the outcomes between Low-profile Visualized Intraluminal Support (LVIS) and non-LVIS stents. ⋯ Overlapped LVIS stenting combined with coiling is feasible and safe for BBAs. Overall, the LVIS stent provided less risk of BBA recurrence compared with the non-LVIS stent and did not increase the risk of procedure-related complications.

Carotid injury during anterior skull base approaches is promptly recognizable and mandates immediate treatment; likewise, development of pseudoaneurysms after such injuries is anticipated and managed. ⋯ The bleeding is brisk and arterial but easily controlled. Immediate postoperative angiography is negative, necessitating repeated angiography to depict the delayed formation. It is best treated by endovascular means that maintains patency of the carotid artery, calling for the development of a suitable device that obliterates the opening of the pseudoaneurysm while maintaining carotid flow that is deployable in the tortuous carotid artery.

Clinical Trial
Assessment and treatment of peritumoral cortical veins in parasagittal meningiomas with application of 3D imaging fusion model.
Operation of cortical veins is the keystone of parasagittal meningioma (PSM) resection. Little is known about pathologic changes of the veins and proper treatment. We built 3-dimensional (3D) image fusion models by neuronavigation to analyze the features of peritumoral cortical veins for PSMs and explore intraoperative treatment options. ⋯ The anastomoses of cortical veins may provide compensation for venous transaction. There may be a time-evolution relationship between different cortical veins (type a to c to b). Treatment of cortical veins should follow the following principles: single-end veins must be protected, tumor-to-end veins should be transacted directly, and end-to-end veins could be cut selectivity based on the degree of occlusion of the superior sagittal sinus. Detailed preoperative assessment of peritumoral cortical veins is critical for proper treatment.
