             arteriovenous malformation, aortic arch dissection, other central nervous system

             aneurysm requiring treatment;
          7. Massive infarction on imaging;
          8. Patients who are unable to cooperate due to epileptic seizure at the onset of stroke

         21. Serious hepatic impairment or serious renal insufficiency;
         22. Subjects who have participated in another investigational study and used
             investigational product before screening;
