Considering the fact that stroke patients admitted during non-office hours were in more severe clinical condition we found no differences in outcome. Fear of impaired access to sophisticated treatment options during non-office hours could be dispelled by the fact, that rate of thrombolytic treatment was even higher during night and weekend. Therefore, our data do not confirm a weekend effect or night effect on stroke treatment. Delay in request of medical care of mildly affected patients that suffer from stroke on weekends confirms need for educational efforts.

Accurate assessment of stroke is critical for patient prognosis and selection of appropriate treatment regimens in order to optimize patient outcomes. Advanced neurosonologic techniques are straightforward, portable, and cost-effective, representing significant advantages over other noninvasive imaging modalities for monitoring of the hemodynamic status of acute ischemic stroke. Ultrasound findings acquired both early (<3 h from onset of stroke) and later (6–24 h after stroke) have demonstrated feasibility and validity for the detection of stenosis/occlusion of key intracranial structures, such as the middle cerebral artery, and for immediate and unambiguous indication of flow velocities, particularly when contrast enhancement is used. In addition, the target of thrombolysis can be identified and localized, and the success of therapy monitored, by transcranial ultrasound. Finally, transcranial ultrasound can be used to gauge the appropriateness of more complex and costly imaging studies, thereby optimizing utilization of health care resources.
