Case ReportsSuperselective Provocative Test with Propofol Using Motor-Evoked Potential Monitoring for Managing Cerebral Arteriovenous Malformations Fed by the Anterior Choroidal Artery.
When feeder artery obliteration is performed via an endovascular procedure to treat cerebral arteriovenous malformation (AVM), it is important to prevent the ischemic complications that are associated with feeder occlusion. A provocative test may be beneficial in some cases to protect against ischemic complications. ⋯ The patient underwent a superselective provocative test with a 3 mg of propofol under general anesthesia using motor-evoked potential monitoring. The feeder embolization was performed as planned after the provocative test, and the patient exhibited no neurological deficits, such as hemiparesis, during the procedure.

Prophylactic Use of Antiepileptic Drugs in Patients with Spontaneous Intracerebral Hemorrhage.
The effect of prophylactic antiepileptic drugs (AEDs) on mortality and functional outcome in patients with intracerebral hemorrhage (ICH) is uncertain. ⋯ Patients with higher ICH scores and larger hemorrhages are more likely to receive prophylactic AEDs. We found no independent effect of prophylactic AED treatment on outcome after ICH.

Prescribing Aerobic Exercise Intensity without a Cardiopulmonary Exercise Test Post Stroke: Utility of the Six-Minute Walk Test.
The cardiopulmonary exercise test (CPET) is an established method for determining target exercise training intensity (ventilatory threshold [VAT]) and cardiovascular risk; unfortunately, CPET is not readily accessible to people post stroke. The objective of this study was to determine the utility of the 6-minute walk test (6MWT) as a less resource-intensive alternative to CPET for prescribing exercise intensity to people post stroke with motor impairments. ⋯ The 6MWT-hr was not interchangeable with the target training VAT-hr determined by CPET. However, in combination with CPET, the 6MWT will indicate when deficits preclude walking alone as the primary exercise modality for optimizing cardiovascular fitness. Future studies to develop a less resource-intensive, multimodal alternative to the CPET for prescribing exercise are needed. A modality that minimizes the effect of stroke deficits, specifically poor balance, should be included.

Observational StudySevere Hemorrhagic Transformation after Thrombolysis for Acute Ischemic Stroke Prevents Early Neurological Improvement.
Intravenous thrombolysis can improve neurological outcomes after acute ischemic stroke (AIS), but hemorrhagic transformation (HT) of the infarct remains a risk. Current definitions for symptomatic intracerebral hemorrhage (ICH) all entail that there be some degree of associated neurological deterioration. However, early deleterious effects of secondary ICH might also be manifested as reduced neurological improvement. This study aims to investigate whether there are any independent associations between different radiological subtypes of HT and the degree of neurological improvement 24 hours after thrombolysis. ⋯ The PH2 subtype of HT is associated with reduced neurological improvement or deterioration 24 hours after thrombolysis for AIS.

Case ReportsCerebral Venous Thrombosis Associated with Intracranial Hemorrhage and Timing of Anticoagulation after Hemicraniectomy.
Cerebral venous thrombosis (CVT) is a rare cerebrovascular event that can present with headache, seizure, and focal neurological deficits. Approximately 30%-40% of patients with CVT also present with intracranial hemorrhage. Current guidelines recommend anticoagulation after CVT even in the setting of intracranial hemorrhage, but the timing of initiation is unclear. We present a case of CVT where timing of anticoagulation was unclear by current guidelines. ⋯ This case illustrates the challenge of determining when to resume anticoagulation for CVT.
