Vascular neurosurgery has developed significantly in Nigeria, but its burden and challenges remain unclear. This study systematically reviewed vascular neurosurgical literature from Nigeria. ⋯ This study illustrates the epidemiological burden of neurovascular pathology (based on the available data in published literature) in Nigeria, and raises awareness amongst service providers and researchers of the attendant challenges and epochal trends seen within vascular neurosurgery in Nigeria.

Approximately 25% of intracranial aneurysms originate at the internal carotid artery and posterior communicating artery (PCoA) junction.1 In contrast to typical PCoA aneurysms, which are usually saccular, a subset known as true PCoA aneurysms arise directly from the PCoA. These represent about 1.3% of all intracranial aneurysms and 6.8% of PCoA aneurysms.1 The first report of a true PCoA aneurysm was in 1979.2Video 1 illustrates the microsurgical clipping of a true PCoA aneurysm in a 27-year-old man with subarachnoid hemorrhage and left-sided ophthalmoplegia. ⋯ The patient had an uncomplicated recovery and was discharged on postoperative day 5 with resolved third nerve dysfunction. A literature review from 2022 documented only 47 cases of true PCoA aneurysms, predominantly manifesting with rupture.3 Some studies suggest that these aneurysms may have a higher rupture risk than typical internal carotid artery-PCoA junction aneurysms.4 Microsurgical clipping is a primary treatment, often in cases associated with a fetal posterior cerebral artery variant.5 Ensuring the patency of the PCoA and thalamoperforating arteries is crucial, with careful visualization of the clip's distal ends to avoid impacting nearby neurovascular structures.

This study analyzed the effectiveness and safety of ultra-low dose fluorescein sodium (FL)-guided malignant glioma resection and its potential to predict the pathological characteristics of glioma. ⋯ Ultra-low-dose FL-guided resection of malignant gliomas is safe and effective. The Ki67 positivity rate was directly proportional to the intensity of FL, indicating its potential to predict gliomas during pathological examination.

This was a single-institutional retrospective cohort study. ⋯ The online wound-related risk calculator was found to accurately predict wound infections but not wound reoperations within our metastatic spine surgery cohort. We suggest that the model may be clinically useful despite underlying population differences, but further work must be done to generate and validate accurate prediction tools.

Soft tissue defects and persistent cerebrospinal fluid (CSF) leaks can create complications after cervical spinal surgery. The supraclavicular artery island (SAI) flap is useful in closing tissue defects, particularly in these complex surgeries and multiple reinterventions. However, technical reports in this context are scarce. We describe application of the SAI flap technique to control persistent CSF leak in the first documented instance (to our knowledge) of a low-grade fibromyxoid sarcoma (LGFMS) in the cervical epidural space. Additionally, we conducted a comprehensive review of PubMed, Embase, and Google Scholar from their earliest records through December 17, 2023 using combined terms, "supraclavicular artery island flap AND spine" and "supraclavicular AND flap AND spine". ⋯ The SAI flap technique provided wound defect coverage in this case and is suitable for addressing issues such as persistent CSF leaks or soft tissue coverage after cervical spine surgery.
