Safety of protocol violations in acute stroke tPA administration.
Intravenous (IV) tissue plasminogen activator remains the only approved therapy for acute ischemic stroke (AIS) in the United States; however, less than 10% of patients receive treatment. This is partially because of the large number of contraindications, narrow treatment window, and physician reluctance to deviate from these criteria. ⋯ Despite more than one third of patients receiving thrombolysis with protocol violations, overall rates of hemorrhage remained low and did not differ from those who did not have violations. Our data support the need to expand access to thrombolysis in AIS patients.

Case ReportsEndovascular treatment for cerebral septic embolic stroke.
This case demonstrates an alternative approach to cerebral revascularization by performing both intravascular mechanical thrombectomy and local injection of thrombolytics that may reduce mortality, bleeding, and the diminished quality of life experienced by patients following an acute septic embolic stroke.

Does symptom onset to primary stroke center time goals affect stroke outcome?
Treating acute ischemic stroke (AIS) within 4.5 hours and door-to-needle time of less than 60 minutes may optimize recovery. It is unknown if onset to Primary Stroke Center (PSC) time goals affect outcome. The purpose of this study was to examine effects of symptom onset to PSC time goals on outcome. ⋯ In our Comprehensive Stroke Center (CSC), onset to PSC time goals were not significant predictors of the 90-day outcome. Expedited care processes in CSC may compensate for differences in outcome. These results should be validated in a larger cohort and in PSCs versus CSCs.

Specific needs for telestroke networks for thrombolytic therapy in Japan.
The concept of telestroke networks has been proposed to overcome regional disparities in stroke treatment. Such networks do not yet operate in Japan. We aimed to determine the specific needs for telestroke networks and to estimate the effects on the number of thrombolytic therapies. ⋯ If 24/7 full telestroke support was introduced to the existing hospitals, 6.8-69.3 more patients could be treated by intravenous (IV) tPA annually. These numbers exceeded the estimated annual increases of .8-13.7 more patients if a drip-and-ship telestroke network was introduced into an underserved area outside the 60-minute-driving-time area. This study uncovered that many Japanese stroke hospitals, especially low-volume facilities located in rural areas, do not perform IV tPA therapy in 24/7 fashion and telestroke support to these hospitals may be highly effective compared with the drip-and-ship network in an underserved area.

Case ReportsA rare cause of embolic stroke in hereditary hemorrhagic telangiectasia.
A 57-year-old male patient with hereditary hemorrhagic telangiectasia presented with an acute right middle cerebral artery ischemic stroke. Investigations revealed a right middle cerebral artery M2 occlusion, hypoxemia, and a large pulmonary arteriovenous malformation and right lower limb deep venous thrombosis. Closure of the pulmonary arteriovenous malformation was successfully performed with an Amplatzer device. Catheter closure of pulmonary arteriovenous malformations in patients with hereditary hemorrhagic telangiectasia is a recognized treatment modality to prevent recurrent ischemic stroke and other embolic and hemorrhagic complications.
