Age and comorbidity burden of patients going anterior cervical discectomy and fusion (ACDF) have increased significantly over the past 2 decades, resulting in increased expenditures. Non-home discharge after ACDF contributes to increased direct and indirect costs of postoperative care. The purpose of this study was to identify independent prognostic factors for discharge disposition in patients undergoing ACDF. ⋯ Numerous sociodemographic and clinical characteristics influence the risk of non-home discharge and discharge to inpatient rehabilitation in patients undergoing ACDF. Policy makers and payers should consider these factors when determining appropriate preoperative adjustment for risk-based reimbursements.

Radiation-induced telangiectasia of the central nervous system has been described predominantly in children, with up to 20% of patients affected after 3-41 years of radiotherapy.1,2 We present the case of a 45-year-old male with a pontine pilocytic astrocytoma treated with standard-dose radiation for 6 weeks in 1993. He developed a 3-cm multicystic, hemorrhagic brainstem lesion but was asymptomatic. The lesion caused severe brainstem mass effect, compatible with cavernous malformation or capillary telangiectasia.3 It has been reported that cavernomas and capillary telangiectasias share a similar pathologic process.4,5 The patient was surgically treated with a supracerebellar infratentorial approach to diagnose the hemorrhagic component of the lesion and ensure there was no transformation of the pilocytic astrocytoma (Video 1). ⋯ From the surgeon's perspective, capillary telangiectasias appear similar to cavernous malformations on gross inspection, so pathologic confirmation is essential. Postoperative imaging demonstrated total resection of the lesion. The patient was discharged on postoperative day 3 with no neurologic deficit.

Postoperative seizures are potential complications of chronic subdural hematoma (cSDH). Knowledge of risk factors may help to identify patients that may benefit from antiepileptic prophylaxis. ⋯ Perioperative antiepileptic prophylaxis may be recommended in patients with preoperative midline shift. Membranectomy may not be routinely applied during surgery.

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.

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.
