| To evaluate the clinical significance of the echogenic vasculature in the baseal ganglia of premature infantswith hypoxic episode, we retrospectively reviewed the cranial sonograms of 19 premature in fants who showedechogenic vasculatures in the basal ganglia. We arbitratily grouped the echogenicity of basal ganglia vasculatureas group I, when the echogenicity was lower ; group II, when the echogenicity was the same ; group III, when theechogenicity was higher than the echogenicity of Sylvian fissure. We analysed the incidence and degree ofintracranial hemorrhage and follow-up sonographic brain abnormalities regarding each group of echogenicvasculatures. group I echogenicity (7 cases) revealed 2 cases of germinal matrix hemorrhage (GMH), 1 case of gradeI intraventricular hemorrhage (IVH), 4 cases of grade II IVH. Out of 7 cases, 2 cases showed ventriculardilatation in the follow-up brain sonograms. Group II echogenicity (8 cases) revealed 5 cases of grade II IVH, 3cases of grade III IVH, in teh follow-up brain sonograms, there were 5 cases of periventricular leukomalacia, 1case of ventricular dilatation and 1 case of brain atrophy. Grade III echogenicity (4 cases) showed 1 case ofgrade II IVH and 3 cases of grade III IVH. They all showed brain atrophy in the follow-up sonograms. We concludedthat the echogenic vasculature of the basal ganglia in premature infant can reflect the degree of initial hypoxicinsult and could be applied as a prognostic indicator. |
