Platelet aggregation was studied by giving ADP or adrenalin to 28 patients with Moyamoya disease. There were 7 males and 21 females, and 27 normal controls, 11 males and 16 females. We found that 2 μM of ADP, and 9.1 and 22.7 μM of adrenalin induced statistically significant increases in nondissociative patterns of platelet aggregation in the patient group. Maximum aggregation was significantly increased in the patient group compared with the controls by the addition of ADP (2 and 4 μM) or adrenalin (9.1 and 22.7 μM). When patients were divided into two groups under and over 20 years of age, there was no discernible difference of platelet aggregation in either group.

    Background. To establish multiple bypass flow in an adult Moyamoya disease patient, the distal stump of the parietal superficial temporal artery (dsPSTA) was used as an additional donor. Methods. Its potential as the donor was first evaluated by measuring the arterial pressure directly in three...
