The health care expenditure in Vietnam is equivalent to 1% of that in the United States. For most patients with brain arteriovenous malformations (AVM), surgery is the only available treatment modality. This study reports on the outcomes on AVM microsurgery in this resource-restricted environment. ⋯ Notwithstanding the limitation in health care resources in Vietnam, surgery for AVMs was successful in eliminating the malformation, with obliteration rates and morbidity comparable with international standards.

This study aimed to predict methylation status of the O6 methylguanine-DNA methyltransferase (MGMT) gene promoter status by using magnetic resonance imaging radiomics features, as well as univariate and multivariate analysis. ⋯ This study showed that radiomics using machine learning algorithms is a feasible noninvasive approach to predict MGMT methylation status in patients with glioblastoma multiforme cancer.

To report the perioperative complication rates in elderly patients undergoing lumbar arthrodesis and to analyze the risk factors. ⋯ The risk factor of perioperative complication in elderly patients after lumbar arthrodesis was fusion segment (≥3), and BMI was a protective factor. Elderly patients with BMI <24.32 are more likely to have perioperative complications after lumbar arthrodesis.

Surgical treatment of large and giant pituitary adenomas is challenging and associated with higher risk of complications and lower rate of gross total resection. We present our experience with surgical management of large and giant adenomas using the extended endoscopic transsphenoidal approach (EETA). ⋯ EETA can be a safe and efficient approach as the first-line treatment of patients with large and giant pituitary adenomas and is associated with high rates of gross total resection or near-total resection, visual function improvement, and a relatively low rate of complications.

Current guidelines recommend the administration of nimodipine for the prevention of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). However, nimodipine can lead to significant drops in mean arterial pressure and cerebral perfusion pressure. Catecholamines are then used to maintain them while nimodipine is reduced and/or held. There is no evidence that nimodipine retains its neuroprotective effect at lower doses. We aimed to investigate the role of nimodipine interruption in the setting of aSAH and its possible impact on the incidence of DCI. ⋯ Our analysis reveals a greater incidence of DCI in patients with aSAH when nimodipine is interrupted.
