Abstract:
Objective To clinically analyze the frequent stroke localizations of moyamoya disease in order to improve our cognition toward it and reduce missed diagnosis. Methods All 32 patients were prospectively analyzed over the past 10 years in our hospital. Results The ratio of female to male was 1.28 and their age of onset ranged from 7 to 47 years old. Mean age of 5 ischemic stroke patients (15.6%) was 24 and mean age of 21 haemorrhagic stroke patients (65.6%) was 33 while mean age of 6 mixed type stroke patients (18. 8% ) was 32. The frequent ischemic stroke localizations were frontoparietal lobe (60%),temporo-occipital lobe (20%), and periventricular zone (20%). The frequent haemorrhagic stroke iocalizations were periventricular zone (42.8%), ventricle (39.2%), temporo-occipital lobe (10. 8%) and subarachnoid space (7.2%). No cerebellum and brain stem stroke occurred. Conclusion Adult patients usually develop intracranial hemorrhage. Moyamoya disease should be considered severely when adult patients develop periventricular and ventricular intracranial hemorrhage, frontoparietal cerebral infarction or adolescent patients develop ischemic stroke, especially companied with epilepsy.
