Low-middle-income countries (LMICs) share a substantial proportion of global surgical complications. This is compounded by the seemingly deficient documentation of postsurgical complications and the lack of a national average for comparison. In this context, the implementation of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) that compares hospital performance based on postsurgical complication data provided by a wide array of centers, could be a major initiative in a resource-challenged setting. Implementation of the NSQIP has provenly mitigated postoperative morbidity and mortality across many centers all over the world. To our knowledge, this report is the first from an LMIC to report its postoperative neurosurgical complications in comparison with international benchmarks. ⋯ Implementation of the NSQIP is an important first step in creating a culture of transparency, safety, and quality. This is the first report of NSQIP implementation in an LMIC, and we have shown comparable results to developed countries.

Endovascular treatment (EVT) is less effective for intracranial atherosclerosis-induced emergent large vessel occlusion. Extracranial-intracranial (EC-IC) bypass surgery is a possible treatment option to augment cerebral blood flow in the perfusion defect area. We compared the efficacy and safety of EC-IC bypass surgery with those of EVT and maximal medical treatment for acute ischemic stroke. ⋯ Emergency EC-IC bypass surgery is an effective and safe treatment option for intracranial atherosclerosis-induced acute ischemic stroke for which EVT is inadequate.

The radial artery is gaining popularity as a vascular access site for neurointerventional procedures. However, recent analyses of wrist position and radial artery anatomy has suggested that the extended position of the wrist is not always necessary. Therefore, the following cadaveric study was performed to verify these findings. ⋯ These data support several recent clinical studies.

Cerebral arteriovenous malformations (cAVMs) represent tangles of abnormal vasculature without intervening capillaries. High-pressure vascular channels due to abnormal arterial and venous shunts can lead to rupture. Multiple pathways are involved in the pathobiology of cAVMs including inflammation and genetic factors such as KRAS mutations. Neutrophil release of nuclear chromatin, known as neutrophil extracellular traps (NETs), plays a multifunctional role in infection, inflammation, thrombosis, intracranial aneurysms, and tumor progression. However, the relationship between NETs and the pathobiology of cAVMs remains unknown. We tested whether NETs play a role in the pathobiology of cAVMs. ⋯ Our results offer the first evidence of intravascular expression of NETs, which might be associated with vascular inflammation in cAVMs.

Spinal meningiomas constitute 10% of all meningiomas. They most commonly rise in the thoracic spine and are most common in middle aged women; symptoms include progressive myelopathy.1,2 Radiation induced/radiotherapy-associated cranial meningiomas are well described with aggressive behavior; however, radiation-induced spinal meningiomas are extremely rare in the literature.3-7 Our patient had a history of Hodgkin lymphoma treated with neck radiation, and thyroid cancer treated with radioactive iodine/thyroidectomy. He presented with neck pain and myelopathy from a large intradural, extramedullary tumor compressing the spinal cord (C3-C5). ⋯ Cervical spine meningiomas with spinal cord compression and myelopathy should be resected to prevent further neurological decline. Dural splitting can be utilized to achieve "radical" tumor resection to prevent recurrence, which is particularly important if the tumor is aggressive and recurrent, as is the case in radiation-induced/radiotherapy-associated meningiomas. Upon dural closure, we applied autologous fat tissue along with fibrin glue to avoid spinal fluid leak as we published earlier.8 The patient consented to the procedure and publication of his image.
