Observational Study
Use of an online referral service for acute neurosurgical referrals: An institutional experience.
We sought to review the current scope of emergency neurosurgical referrals and examine the long-term use of a web-based referral system. ⋯ With an increasing number of referrals, it is feasible to provide traceable advice in a timely manner through an electronic web-based referral system transferable to any specialty. Insights could be used to direct resources and workforce planning according to emergency referral patterns.

Giant colloid cysts are defined as cysts of more than 3 cm in maximal diameter. Few cases of giant colloid cysts have been reported in the literature. We herein describe a giant colloid cyst. ⋯ Five years following surgical resection, a brain magnetic resonance imaging did not demonstrate any evidence of residual or cyst recurrence. To our knowledge, giant colloid cysts have been rarely reported and pose a management dilemma in the literature. The present article highlights the symptomatology, radiological findings, and outcome of a giant colloid cyst.

Secretory meningioma (SM) is a rare subtype of World Health Organization (WHO) grade 1 meningioma, associated with significant peritumoral brain edema (PTBE). Because of this, SM may be mistaken preoperatively to be a WHO grade 2 meningioma (G2M). In this study, we identified radiographic features to differentiate these 2 tumor types preoperatively to help inform surgical decision-making. ⋯ In this study, we found that preoperative FLAIR hyperintensity, severe PTBE, and higher nADC values correlated with SM pathology, and larger size and cystic component were associated with G2M. Accurate identification of SM on preoperative imaging may provide surgeons useful information in decision-making.

The objective of this study was to compare the safety and clinical efficacy of full-endoscopic lumbar interbody fusion (FE-LIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). ⋯ FE-LIF, which is safe, effective, and minimally invasive, exhibits the same clinical efficacy as MIS-TLIF but with longer operation time and increased radiation exposure.

Analysis of results of surgical treatment of 112 patients with large and giant anterior cerebral artery (ACA) aneurysms. ⋯ Microsurgery provides effective and relatively safe occlusion of complex ACA aneurysms. Direct clipping can be applied in most cases independent of their precise location. In certain cases, alternative methods can be safely used. According to multivariate analysis, giant aneurysm size, aneurysm-related mass effect, involvement of large arterial branches in the aneurysm wall, and intraoperative complications were significant predicting factors for ischemic complications.
