A cavernous sinus (CS) dural arteriovenous fistula (DAVF) is a form of abnormal arteriovenous communication that can be treated with endovascular embolization. Establishing an optimal access route should be based on vascular architecture. We reviewed 64 patients with CS-DAVF who underwent endovascular embolization and report the endovascular treatment approach selection and outcome. ⋯ The vascular architecture of CS-DAVF is closely related to endovascular treatment approach selection and outcome. Combined with the modified IPS recanalization technique, the trans-IPS approach is the safest and most effective approach. Dual microcatheter and balloon assistance techniques ensure the safety and completeness of embolization.

Africa has an increased burden of neurosurgical diseases with an estimate of 1,986,392 neurosurgical cases, 108,824 neurosurgical case capacity, and 1,877,568 case deficits yearly. Literature suggests that about 8420 neurosurgeons are needed to fill this vast gap. The main objective of this study is to elucidate barriers encountered in pursuing neurosurgery training in the African context. ⋯ Even with its robust population growth, Africa is not producing enough neurosurgeons to meet the demands of the population due to several barriers. Delineating these challenges and barriers represents an important step in developing sustainable mechanisms for recruitment, training, mentorship, and support of burgeoning African neurosurgeons.

A Stereotaxic Atlas of the Human Lumbar-Sacral Spinal Cord has been created to provide an anatomical basis for radiologic and ultrasonic imaging and electrophysiological examination, which are used to target the placement of lumbar-sacral epidural stimulating electrodes and cellular transplantation in order to restore movement in individuals with sustained spinal cord injury or a degenerative disorder of the spinal cord. Through the availability of an atlas that exhibits axial images of the cytoarchitecture of each cord segment with a stereotaxic millimeter grid of dorsal-ventral depth from the midline dorsal surface of the cord and right-left distances from the midline of the cord, neuromodulation, and cellular therapy would undoubtedly be made not only more precise but also safer for patients. ⋯ The atlas provides an anatomical basis for radiologic and physiologic confirmation of target localization in the lumbar-sacral spinal cord.

Mobile stroke units (MSUs) have been implemented worldwide for stroke care, but outcome data are lacking to show their efficacy specifically in patients undergoing mechanical thrombectomy (MT). Here, we include patients from our stroke network MSU and compare them to patients who arrived conventionally. ⋯ Our pilot study demonstrates the efficacy of the MSU in decreasing door-to-puncture time and a concordant improvement in the discharge modified Rankin Scale score. Further prospective studies are needed to assess cost-efficacy and optimal protocol for MSUs in stroke care.

Prelemniscal radiation (Raprl) lesions and deep brain stimulation effectively control motor symptoms of Parkinson disease, but individual variations in the stereotactic location of its fiber components constitute a significant concern. The objective of this study was to determine individual variations in the stereotactic location of fiber tracts composing Raprl. ⋯ Individual PMP variations for fiber tracts in Raprl, identified by probabilistic tractography, provide a platform for planning the stereotactic approach to conform volumes for deep brain stimulation and lesions.
