This survey was conducted to explore the perceptions of undergraduate (UG) medical students regarding enrolling in a neurosurgical training program. The purpose was to understand' expectations, reasons, apprehensions, and variables influencing students' decisions to pursue a career in neurosurgery. The results shed light on students' perceptions and can help educational institutions and training programs draw in and encourage aspiring neurosurgeons. ⋯ Our study reveals that although a majority of the UG students would like to join neurosurgery residency, there are significant barriers in the form of less exposure, negative perceptions, and apprehensions toward the branch. Enhancing medical students' awareness about neurosurgery necessitates the integration of hands-on workshops, simulation-based training, didactic lectures, and neurosurgery rotations into the UG curriculum.

In >70% of patients with hemifacial spasm (HFS), the offending artery is either the anterior inferior cerebellar artery (AICA) or posterior inferior cerebellar artery (PICA), without a tortuous vertebrobasilar artery (VBA). We hypothesized that anchoring perforators around the root exit zone (REZ) of the AICA or PICA might induce vascular deviation and compression. We investigated the occurrence of these perforators from the AICA or PICA and the extent of VBA tortuosity to reveal the pathology of vascular compression. ⋯ Anchoring perforators around the REZ play a crucial role in vascular compression for patients with less tortuous VBAs. Moreover, surgeons should be prepared to deal with multiple perforators in a more complicated surgery in cases of less tortuous VBA.

Intracranial arteries have a high rate of variation, but a clear schematic overview is lacking. In this pictorial review we classify and depict all variations and anomalies within the anterior communicating artery complex. ⋯ The anterior communicating artery complex consists of the anterior cerebral artery, anterior communicating artery and the recurrent artery of Heubner. An overview of these variations may be helpful in distinguishing pathology from anatomical variations, assist neurosurgeons during clipping of cerebral aneurysms, and support interventional radiologists during endovascular treatments. This article summarizes the current knowledge of anatomical variations within the anterior communicating artery complex, their prevalence and clinical relevance. A total of 42 variants were identified and schematically depicted. We encourage all who diagnose, treat, and study the anterior communicating artery complex to use this overview for a uniform and better understanding of its anatomy.

Patients who present with a large colloid cyst (CC) and nondilated ventricles represent a therapeutic challenge.1-3 Although transcallosal approaches provide reliable access to the lateral ventricle and foramen of Monro, direct visualization of the vascular attachment of the CC to the roof of the third ventricle is not always possible. This can be especially true with CCs located more posteriorly and superiorly.4 Opening of the choroidal fissure can improve access and visualization to the posterior third ventricle; however, this maneuver is associated with some element of risk.5 There is a paucity of operative video in the literature illustrating the technique of gentle, microblade elevation of the fornix to improve visualization into the third ventricle and, on occasion, avoid the need to open the choroidal fissure.6 We report the case of a 28-year-old woman who presented with headaches and progressive short-term memory dysfunction (Video 1). Magnetic resonance imaging demonstrated a 17-mm CC associated with distortion and thinning of the bilateral fornices without hydrocephalus. ⋯ The index operative video discusses the technical nuances associated with trans-callosal resection of CC with use of the microblade retractor. Special emphasis is placed on the intricate relationship of neighboring anatomic structures. The patient consented to the procedure and the publication of her image.

To examine the association between vertebral cancellous Hounsfield units (HUs), age, bone mineral density, and T-score in a sample of Chinese adults. ⋯ From the findings of this study, it can be concluded that HUs may be a potential predictor of bone health, with implications for presurgical assessment of the quality of bone-screw interfaces for spinal surgery.
