Case Reports5-fluorouracil-induced leukoencephalopathy with acute stroke-like presentation fulfilling criteria for recombinant tissue plasminogen activator therapy.
A 61-year-old man underwent systemic chemotherapy with intravenous infusion of nedaplatin and 5-fluorouracil. On the day after the final drug administration, he suddenly experienced difficulty in speaking followed by left-sided weakness. His National Institutes of Health Stroke Scale score was 12. ⋯ An initial magnetic resonance imaging scan of his brain revealed a hyperintense area in the bilateral white matter and corpus callosum, and these abnormalities had improved on the follow-up scan. We diagnosed him with 5-fluorouracil-induced leukoencephalopathy with acute stroke-like presentation. Our experience suggests that 5-fluorouracil-induced leukoencephalopathy potentially fulfills all eligibility criteria for recombinant tissue plasminogen activator therapy.

Aphasia predicts unfavorable outcome in mild ischemic stroke patients and prompts thrombolytic treatment.
Patients with an acute ischemic stroke rated as mild, and for this reason not submitted to thrombolysis, have an unfavorable outcome in a non-negligible proportion. Whether selective presentation features help identify those at risk of bad outcome, and whether it could be recommended to treat only patients with such features, is poorly elucidated. We report our experience based on retrospective evaluation of a consecutive series of patients scoring 6 or less on baseline National Institutes of Health Stroke Scale (NIHSS), some of whom received thrombolysis. ⋯ Aphasia is an early marker of unfavorable outcome in mild ischemic stroke patients. In these patients thrombolysis should be considered beyond the NIHSS scoring.

Case ReportsDabigatran-related intracerebral hemorrhage resulting in hematoma expansion.
Warfarin-related intracerebral hemorrhage carries a particularly high risk of neurologic deterioration and death because of a high rate of hematoma expansion of about 50%. Novel oral anticoagulants (NOACs)--apixaban, dabigatran, and rivaroxaban--have a significantly smaller risk of intracerebral hemorrhage (ICH). ⋯ Second, there is no specific antidote for neither of the NOACs. We present a case that suggests that hematoma expansion may occur after NOAC-related ICH.

Decompressive surgery for malignant cerebral venous sinus thrombosis: a retrospective case series from Pakistan and comparative literature review.
Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke in the West; however, it is prevalent in Asia and the Middle East. CVST is treated with dose-adjusted heparin or heparinoid followed by warfarin to facilitate recanalization of venous sinuses. For those with progressive malignant cerebral edema, the role of decompressive surgery has been reported from developed countries. We present data on decompressive craniectomy from a tertiary care stroke center in a developing country and compare our results and population with that described in the international literature. ⋯ Patients who received decompressive hemicraniectomy in Pakistan for CVST had excellent outcomes in all cases when intervention was performed with intact preoperative pupillary reflexes. Of the data reviewed, most reported (two-third) patients show the same prognosticators; however, one third show that even with nonreactive pupils complete recovery is possible.

Comparative StudyRelative changes in transcranial Doppler velocities are inferior to absolute thresholds in prediction of symptomatic vasospasm after subarachnoid hemorrhage.
The absolute transcranial Doppler (TCD) velocity threshold has been validated as a screening tool for vasospasm after subarchnoid hemorrhage (SAH). We assessed whether relative changes in velocity were superior to absolute TCD thresholds in the detection of symptomatic vasospasm. We reviewed consecutive patients with aneurysmal SAH who underwent serial TCD monitoring and survived at least 7 days. ⋯ The best characteristics were observed for the combination of MFV >175 cm/s and/or maximal LR >6 (AUC 0.81). Our data suggest that absolute thresholds of TCD FVmean provide the most accurate prediction of symptomatic MCA vasospasm after SAH. Other thresholds, including relative change from baseline and day-to-day changes, are inferior to established absolute thresholds.
