To compare patient-reported outcomes (PROMs), satisfaction, and minimum clinically important difference (MCID) achievement following minimally invasive transforaminal lumbar interbody fusion stratified by preoperative disability. ⋯ Preoperative disability associated with worse postoperative PROMs and patient satisfaction for disability, back/leg pain at multiple time points. MCID achievement rates across cohorts were similar for most PROMs at most postoperative time points. Patients with severe disability may have unrealistic expectations for surgical benefits, influencing corresponding postoperative satisfaction.

Preoperative diagnosis of prolactinomas is critical because dopamine agonists have been regarded as a primary treatment. However, serum prolactin level alone is suboptimal for differentiating prolactinomas from hyperprolactinemia-causing non-functioning pituitary adenomas (NFPAs). By using the tumor size, the authors tried to investigate an effective parameter for the discrimination. ⋯ PDR2 was a more effective indicator than prolactin alone in the preoperative differential diagnosis of prolactinomas and NFPAs, which may help select patients who need medical treatment first.

In current neurosurgical practice, treatment paradigms for posterior circulation aneurysms have shifted away from microsurgical clip ligation toward endovascular therapy. This is largely due to the results of the International Subarachnoid Aneurysm Trial and International Study of Unruptured Intracranial Aneurysms, which, in part, showed that outcomes in patients with ruptured aneurysms were better with coiling and that a location in the posterior circulation was an independent risk factor for poor outcome, respectively.1,2 Nevertheless, there exist certain anatomic features that highlight the importance of a microsurgical approach. ⋯ Endovascular options were deemed less favorable due to the small size of the aneurysm and the hemorrhagic complications associated with dual-antiplatelet therapy in the setting of an acute subarachnoid hemorrhage. A standard right-sided orbitozygomatic approach was performed.3 This video highlights the importance of performing microsurgical clipping for posterior circulation aneurysms in an era with increasing reliance on endovascular treatment.

Pituitary apoplexy is a rare clinical syndrome. Only a few studies have examined factors associated with recovery of neuroendocrine functions following transsphenoidal surgery. This study aimed to identify factors associated with neuroendocrine recovery following surgery for pituitary apoplexy. ⋯ Older age, higher suprasellar extension, and hypertension were poor prognostic factors for visual recovery. Wilson-Hardy inferior invasion grade 3-4 and lower preoperative serum prolactin level were poor prognostic factors for recovery from hypopituitarism. Stratifying patients according to these prognostic factors may assist in selecting patients for surgery.

Intraaxial tumors of the central lobe are challenging lesions to deal with because of the high eloquence of this anatomic area.1,2 Diffusion tensor imaging magnetic resonance imaging and fluorescein (F) have proven to be useful in the planning and execution, respectively of glioma surgery.3-9 Nevertheless, the advantages of intraoperative use of augmented reality (AR) with diffusion tensor imaging-based high-definition fiber tractography (HDFT) are still underestimated. In the AR HDFT-F technique reported by our group, the integration of AR into the microscope comes through the BrainLAB Curve navigation platform (BrainLAB AG, Munich Germany), Smartbrush software (BrainLAB AG), KINEVO 900 surgical microscope (Carl Zeiss, Oberkochen, Germany), and YELLOW 560 filter (Carl Zeiss).9 The microscope establishes a wired autodetection of the navigation platform, and the eyepiece functions as a "see-through display" of the AR images, which are overlapped onto the surgical field. Video 1 shows the technical key aspects of the intraoperative use of the AR HDFT-F technique in the maximal safe anatomic resection of a postcentral gyrus high-grade glioma.
