Combination of Dexmedetomidine and Ketamine for Magnetic Resonance Imaging Sedation
Conclusions: The efficacy of DEX–KET sedation was comparable to that of midazolam for MRI examination. DEX–KET was related to shorter scan time and lower occurrence of complications compared to midazolam. Introduction Neurocritically ill patients often require brain magnetic resonance imaging (MRI) in addition to conventional neurological evaluations. Brain MRI can reveal structural lesions with a high sensitivity due to its excellent spatial resolution and enhanced soft tissue contrast (1–3). To acquire MRI images, patients' cooperation is imperative. However, keeping patients with ...

Successful Treatment of Growing Basilar Artery Dissecting Aneurysm by Pipeline Flow Diversion Embolization Device
We describe a case of successful management of a growing basilar artery dissecting aneurysm by the Pipeline flow diversion embolization device (PED). A 48-year-old woman presented with severe headache, neck pain, and altered consciousness. Computed tomography showed subarachnoid hemorrhage located in basal cisterns, with a pontine infarct shown on magnetic resonance imaging. Digital subtraction angiography showed dissecting aneurysm of the trunk of the basilar artery, with growth over time on repeated imaging. Repeated imaging demonstrated growth in size of the aneurysm. The aneurysm was treated with PED with complete obl...

Pre-injury Comorbidities Are Associated With Functional Impairment and Post-concussive Symptoms at 3- and 6-Months After Mild Traumatic Brain Injury: A TRACK-TBI Study
Conclusions: Pre-injury psychiatric and pre-injury headache/migraine symptoms are risk factors for worse functional and post-concussive outcomes at 3- and 6-months post-mTBI. mTBI patients presenting to acute care should be evaluated for psychiatric and headache/migraine history, with lower thresholds for providing TBI education/resources, surveillance, and follow-up/referrals. Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT01565551. Introduction Traumatic brain injury (TBI) remains a significant cause of morbidity and mortality worldwide. In 2013 ~2.8 million TBI cases were recorded an...
