Repositioning Technique for the Decompression of Symptomatic Dolichoectatic Vertebrobasilar Pathology: A Comprehensive Review of Sling Characteristics and Surgical Experiences.
The repositioning of a dolichoectatic vertebrobasilar artery (VBA) for arterial decompression has been extensively used in the clinical setting. We aimed to describe and summarize the technical characteristics and clinical results of the sling technique. ⋯ The excellent surgical outcomes and durable long-term results suggest that the repositioning technique is highly effective in resolving symptoms related to the compression of DVB pathology. The wrap-sling technique might be the preferred option owing to the simultaneous symptom relief and lower rate of temporary complications. However, cranial nerve manipulation should be meticulously implemented to avoid permanent negative effects.

Review Case Reports
Primary Diffuse Leptomeningeal Melanomatosis: Case Report and Review of the Literature.
Primary diffuse leptomeningeal melanomatosis (PDLM) is an extremely rare pathologic condition that can mimic several other neurologic disease states. ⋯ PDLM is an extremely rare disease, and diagnosis is difficult because of nonspecific clinical, radiographic, and laboratory findings. In approximately half of cases, no distinct mass is shown on imaging workup, which may further complicate diagnosis. PDLM should be on the differential diagnosis for cases of diffuse dural enhancement. Neurosurgical intervention is often limited to ventriculoperitoneal shunting for increased intracranial pressure and dural and cranial biopsy to obtain diagnosis. If the initial biopsy is nondiagnostic, hypermetabolic activity as seen on positron emission tomography may be helpful to find an alternative biopsy site.

Review Historical Article
Neurological Functional Surgery in Mexico: From Pre-Columbian Cranial Surgery to Functional Neurosurgery in the 21st Century.
From the predominance of the pre-Columbian cultures to the present, an interest has existed in Mexico in brain structure and function, in both normal and pathological conditions. This interest has resulted in both medical and surgical attempts to treat some neurological conditions. ⋯ At present, functional neurosurgery in Mexico constitutes, similar to that in other countries, a recognized surgical subspecialty that provides valuable information to treat brain dysfunctions such as movement disorders, pain, epilepsy, and other conditions. In the present report, we have briefly described the main historical aspects of the emergence and development of functional neurosurgery in Mexico.

Review Case Reports
Trigeminal Neuralgia Caused by Dural Arteriovenous Fistula in Meckel Cave Treated with Gamma Knife Radiosurgery: A Case Report.
Classic trigeminal neuralgia is an often debilitating condition that frequently results from vascular compression at the root entry zone of the trigeminal nerve. We report a case of dural arteriovenous fistula surrounding the trigeminal nerve from near the root entry zone extending as far ventral as the Meckel cave treated solely with Gamma Knife radiosurgery. ⋯ This case suggests that trigeminal neuralgia associated with dural arteriovenous fistula can potentially be treated with Gamma Knife radiosurgery; however, more extensive studies and long-term follow-up to evaluate vessel patency will be necessary to elucidate further the role of stereotactic radiosurgery alone in treating this entity.

Meta Analysis Comparative Study
Radiographic and Clinical Outcomes of Oblique Lateral Interbody Fusion Versus Minimally Invasive Transforaminal Lumbar Interbody Fusion for Degenerative Lumbar Disease.
The effects of oblique lateral interbody fusion (OLIF) and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) have not been compared by a meta-analysis. The present study aimed to summarize the radiographic and clinical outcomes of OLIF and MI-TLIF for degenerative lumbar disease. ⋯ The radiographic and functional outcomes and length of hospital stay were similar between the 2 groups. The OLIF group showed advantages in operative blood loss and operative time; however, the incidence of complications in this technique was greater than that in the MI-TLIF group.
