ABSTRACT

De janeiro a dezembro-1986, nasceram 120 crianças com peso ao nascimento inferior a 1500 gramas. Dessas, 85 foram escolhidas para estudo por apresentarem avaliaçäo ultrassonográfica de crânio e/ou estudo necroscópico. A mortalidade do grupo de estudo foi de 70//, porém a mortalidade geral do período foi de 52,5//. A avaliaçäo ultrassonográfica foi realizada em 41 crianças. A incidência de hemorragia peri-intraventricular (HPIV) foi de 42,3//. Vinte e três crianças (63,8//) apresentaram HPIV grau II ou III; 10 apresentaram HPIV grau I (27,7//) e apenas 3 (8,3//) tinham o grau IV. Treze crianças tinham realizado ultrassonografia de crânio e exame necroscópico. Houve concordância total entre as duas avaliaçöes em 9 (69//), enquanto 2 casos (16//) apresentavam concordância parcial, pois o diagnóstico dos graus de HPIV foram divergêntes. Apenas 2 casos apresentavam discorância entre as avaliaçöes de ultrassom e necrópsia. Em ambos a avaliaçäo ultrassonográfica inicial mostrou ausência de hemorragia intracraniana e a necrópsia, HPIV. Entretanto, o óbito ocorreu 20 e 53 dias, respectivamente, após a avaliaçäo sonográfica. Concluimos que a incidência de HPIV foi comparável à referida na literatura e que no exame ultrassonográfico de crânio é bastante confiável para o seu diagnóstico

ABSTRACT

From January to December 1986, 120 preterm infants were born with birth-weight under 1500 gm. Eighty-five infants were included in the study group either because they had a cranial sonographic evaluation or a necropsy. The mortality rate was 70% for the study group, but was 52.5% for the whole period. The sonographic examination was performed in 41 infants. The incidence of periventricular-intraventricular hemorrhage (PIVH) was 42.3%. Twenty-three cases had PIVH grade II (63.8%), 10 grade I (27.7%), and 3 (8.3%) grade IV. Thirteen infants had sonographic and necroscopic examinations. We observed a total agreement between sonographic and necroscopic diagnosis in 9 cases (69%). Two cases were classified as partial agreement as they differed only in the grading of PIVH, whereas in two cases there was a false negative diagnosis in the ultrasound examination. The interval between the examinations in these two false negative cases was 53 and 20 days, respectively. We conclude that the incidence of PIVH found in our study is comparable to that of the literature and that cranial ultrasonography is a sensitive neuroimage technique for the diagnosis of PIVH in the newborn preterm infant.
