TI  - Posterior circulation in moyamoya disease: angiographic study.
PG  - 239-46
AB  - PURPOSE: To clarify the angiographic findings of the posterior circulation in 
      patients with moyamoya disease. MATERIALS AND METHODS: Seventy-six patients with 
      idiopathic moyamoya disease were studied with conventional angiography. The 
      angiographic findings were reviewed for steno-occlusive lesions, collateral 
      vessels, and aneurysms and compared with the finding of parenchymal lesions on 
      computed tomographic and magnetic resonance images. RESULTS: Of 152 posterior 
      cerebral arteries (PCAs), 66 (43%) had a stenotic or occluded lesion. The 
      frequency of PCA lesions statistically significantly increased with the extent of 
      the internal carotid artery (ICA) bifurcation steno-occlusive lesion. As the 
      severity of ICA stenosis increased, basal cerebral moyamoya vessels and 
      transdural collateral vessels similarly increased in number, but leptomeningeal 
      collateral vessels decreased owing to the progressive development of more PCA 
      lesions. Cerebral infarctions, ventricular dilatation, and cerebral atrophy were 
      found to increase in frequency in patients with steno-occlusive PCA lesions. 
      CONCLUSION: Steno-occlusive lesions of the PCA increase in frequency 
      proportionally with severity of ICA bifurcation steno-occlusive lesions, so that 
      cerebral infarctions increase in frequency with the extent of the PCA lesions.
