Randomized Controlled Trial Multicenter StudyAntiplatelet therapy in combination with rt-PA thrombolysis in ischemic stroke (ARTIS): rationale and design of a randomized controlled trial.
Thrombolysis with recombinant tissue plasminogen activator (rt-PA) is currently the only approved acute therapy for ischemic stroke. After rt-PA-induced recanalization, reocclusion is observed in 20-34%, probably caused by platelet activation. In acute myocardial infarction, the combination of thrombolytic and antiplatelet therapy leads to a better outcome compared to thrombolytic treatment alone. In patients with acute ischemic stroke, several studies showed that those on antiplatelet treatment prior to rt-PA had an equal or even better outcome compared to patients without prior use of antiplatelet therapy, despite an increased risk of bleeding. ⋯ This study will answer the question whether the combination of rt-PA and antiplatelet therapy improves the functional outcome in ischemic stroke patients.

Multicenter StudyPreoperative prediction of outcome in 283 poor-grade patients with subarachnoid hemorrhage: a project of the Chugoku-Shikoku Division of the Japan Neurosurgical Society.
The management of patients with poor-grade subarachnoid hemorrhage (SAH) continues to be controversial. The objective of this study was to examine predictors of outcome of poor-grade SAH after surgical obliteration of the aneurysm. ⋯ Advanced age, WFNS grade V, improvement in WFNS grade, and LDA associated with vasospasm on CT were found to be independent predictors of clinical outcome, whereas rebleeding, early aneurysm surgery and treatment modality (surgical clipping or Guglielmi detachable coil embolization) were not independently associated with outcome in patients with poor-grade aneurysm.

Multicenter StudyDoes current oral antiplatelet agent or subtherapeutic anticoagulation use have an effect on tissue-plasminogen-activator-mediated recanalization rate in patients with acute ischemic stroke?
Our goal is to assess if current antiplatelet (AP) use has an effect on recanalization rate and outcome in acute stroke patients. ⋯ No correlation was found between AP use and recanalization rate and good outcome in patients with acute stroke who received IV rt-PA treatment. Prior AP use should not defer patients from receiving IV rt-PA treatment in an acute stroke setting.
