To assess the role of magnetic resonance angiography(MRA) and the effect of
encephaloduroarteriosynangiosis (EDAS) on the pediatric moyamoya disease (MMD). we
analyzed the findings of MRA comparing with conventional angiographr(CA) and
corebral blood flow(CBF) studies using 99mTc-HMPAO SPECT or
H2O15-PET with or without diamox enhancement. and
focusing on change following surgery for EDAS. Our assessment involoved 23 children
with MMD. in whom 44 EDAS procedures were performed.
On MRA compared with CA. stenosis of internal carotid artsries was accurately
visualized in eight of 19 hemispheres (42%) and augmented in 11(58%). The visualized
in two(11%). Changes in the middle and anterior cerebral artery were similirly visible in
both MRA and CA studies.
Evaluation of postoperative MRA showed that at tIns site of surgery, the major
clangs was dilation of the of 19 hemispheres (68%)
In comparison with perioperative CBF studies, basal CBF improved in 23 of 36
hemispheres(54%) within one year of surgery In particular. early improvement of basal
CBF within 3 months. was observed in seven hemispheres(30.4%).
CBF studies with diamox snhancement showed that after surgery. vascular reserve
was normal or improved in eight of 12 hemispheres(67%)
In conclusion, it may be stated that although definitive diagnosis requires further
improvement in the delineation of fine vasculature. MRA promises to a useful alternative
to conventional angiography in the diagnosis and postoperative evaluation of MMD. To
understand the effects of sungery on MMD, perioperative CBF studies are mandatory.
