To treat acute-stage patents with stroke, interdisciplinary medical care by a team of specialized physicians and surgeons from different sections is essential. To this end, the Stroke Center was formed in the Osaka University Hospital.
In the Stroke Center, physicians and surgeons of the Trauma and Acute Critical Care Center, Neurosurgery, and Neurology and Cerebrovascular Diseases stand ready to accept patients with stroke via the Trauma and Acute Critical Care Center as a contact. We are committed to medical care for prevention of recurrence and rehabilitation of the patients after having an examination in the Stroke Center in cooperation with Geriatrics and Hypertension, the Clinic of Radiology, Rehabilitation, the Department of Nursing, and the Patient Support Center, as well as to home rehabilitation and social rehabilitation in cooperation with medical facilities in the community.
The mild patients or those, who intend to have preventive medical care, referred from other medical facilities in the community are accepted by registered medical practitioners and stroke-specialized physicians/surgeons of the Stroke Center in the Internal Medicine clinic and the Neurosurgery clinic every day.
In the Stroke Center, specialized physicians/surgeons of individual clinical sections discuss the treatment policy at case conferences to provide the most appropriate medical services to all the inpatients and some outpatients on an interdisciplinary basis.
The number of treated patients was approximately 500 in total each year, about half of which were acute-stage patients with stroke. We are specialized in all types of cerebrovascular diseases including cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage, TIA etc. Many of them have complex pathology associated with other systemic diseases.

On these patients, we performed various specialized examinations (cerebral angiography, carotid ultrasonography , transcranial Doppler ultrasonography, transesophageal echocardiography, and lower extremity venous ultrasonography) and conducted specialized procedures including endovascular surgery (carotid stenting procedures, coil embolization procedures), surgical clipping of unruptured cerebral aneurysms, and EC-IC Bypass.


Our center is characterized by interdisciplinary medical care services provided to acute-stage stroke patients by a team of specialized physicians and surgeons of specialty sections. At present, a staff of more than 50, many of which are physicians and surgeons specialized in stroke, have been registered in our center. Brain CT, MRI, carotid ultrasonography, transcranial Doppler ultrasonography, and transesophageal echocardiography can be performed any time, and thrombolytic therapy may be applied to patients with diseases susceptible to treatment on a 24-hour basis. Cerebral angiography and single photon emission computed tomography (SPECT) test on cerebral blood flow may be performed any time and interventional stroke therapy may be applied when indicated. We have a solid system capable of rapidly treating patients by surgical procedures and neuroendovascular therapy such as hematoma removal craniotomy and cerebral aneurysm coil embolization.
We provide medical care services to patients with stroke, most of whom suffer from systemic complications, in cooperation with the related clinical sections.

Considerations in referring your patients to the Stroke Center

Please describe in a referral letter which clinical section your patient needs to have an initial examination, Surgery or Internal Medicine, if possible. Your patients will be initially treated by a stroke-specialized surgeon of Neurosurgery if surgery is selected, or a stroke-specialized physician of Neurology and Cerebrovascular Diseases if Internal Medicine is selected.
