Introduction : The validity of intravenous rt-PA therapy for acute ischemic stroke patients within ４．５ hours after onset is reported, but the rate of the delivery of rt-PA therapy is assumed lower due to its lack of stroke specialists and its geographic location in depopulated areas. In February ２０１３, we developed the telemedicine system in our medically under-served area as a potential solution of medical disparities. Objects and Methods : After the introduction for １６ months, ９５ acute ischemic stroke patients were transferred to our hospital, seven （７．３７％） of which were subjected to the “drip and ship” method of rt-PA infusion using a telemedicine system for emergency medicine （k-support）. We examined the time course after onset and the treatment outcome of these seven cases. Results : Seven cases had rt-PA infusion started in the depopulated area. In five cases, recanalization of occluded vessels were demonstrated resulting in improved clinical symptoms. Conclusion : It was able to give a standard therapy using rt-PA infusion for acute ischemic stroke and the quality of the cerebral infarction medical treatment was improved by building the telemedicine system in the depopulated area
