Surgical practice highly depends on the availability of surgical equipment; this is particularly relevant to low- and middle-income countries (LMICs), where resources are limited. A key part of the efforts to improve surgical provision globally include providing affordable equipment to LMICs; however, the effectiveness and the impact of these initiatives have not yet been assessed. We aimed to evaluate the World Federation of Neurosurgical Societies neurosurgical equipment program in this context. ⋯ Equipment donation positively impacts neurosurgical units in LMICs by allowing expansion of neurosurgical practice, improved safety and quality, and affordability. Adequate follow-up, considerations regarding equipment durability and maintenance needs, and improved support for repairs should be prioritized to ensure maximal benefit.

Although sagittal spinal balance plays an important role in spinal deformity surgery, its role in decompression surgery for lumbar canal stenosis is not well understood. To investigate the hypothesis that sagittal spinal balance also plays a role in decompression surgery for lumbar canal stenosis, a prospective cohort study analyzing the correlation between preoperative lumbar lordosis and outcome was performed. ⋯ This study showed that preoperative lumbar lordosis significantly influences the outcome of decompression surgery on lumbar canal stenosis.

Acute lymphoblastic lymphoma is a malignant hematologic disease in childhood but rarely initially involves epidural compartment in adults. A 20-year-old male presented with progressive osphyalgia with constipation. Contrasted magnetic resonance imaging showed multiple vertebrae of hypointense T1 signals and an intraspinal epidural lesion. ⋯ Histopathology suggested malignant B-cell lymphoma with Ki-67 of 90% and positivity of leukocyte common antigen. A bone marrow biopsy was unequivocally diagnostic of B-cell acute lymphoblastic lymphoma followed by chemotherapy (methotrexate) and partial recovery was observed. The marrow biopsy was necessary if without hypercalcemia and abnormal peripheral blood examination.

A contralateral approach to aneurysm clipping in cases of bilateral middle cerebral artery (MCA) aneurysms reduces surgical time and cost. However, there is a lack of evidence for objective patient selection. In this study, we assessed the change in surgical freedom along the contralateral MCA to provide objective evidence for patient selection. ⋯ After the proximal 5 mm, there is no significant decrease in surgical maneuverability within the proximal 10 mm of MCA when approached contralaterally. When compared to the average length of the MCA from its origin to the aneurysm neck in the clinical series, it can be concluded that the first 10 mm (average, 12.4 mm) of the contralateral MCA may be considered a surgical comfort zone for a contralateral approach. This criterion may be useful for patient selection for a contralateral approach in cases of multiple bilateral intracranial aneurysms.

Internal carotid artery (ICA) reconstruction is still the most effective treatment for a blood blister-like aneurysm (BBA) on the supraclinoid segment of the ICA, and clipping after wrapping has the most precise effects. However, the materials used are most often artificial. This study examined the use of autologous dura to replace the artificial materials used for wrapping after suturing a BBA. ⋯ The method we adopted is new and showed satisfactory curative results, suggesting that ICA suturing with dura mater wrapping may become a method for the treatment of a BBA on the supraclinoid segment. The dura could potentially replace the artificial materials used for wrapping the ICA.
