ABSTRACT

OBJETIVO: análise histopatológica das artérias espiraladas do leito placentário em gestações complicadas pelo descolamento prematuro da placenta (DPP) associado à hipertensäo, comparando-as com a estrutura vascular dos leitos placentários normais. MÉTODO: a biópsia do leito placentário foi realizada em 23 gestantes com diagnóstico de descolamento prematuro de placenta associado à hipertensäo (G/HA) e idade gestacional maior ou igual a 28 semanas, submetidas ao parto cesáreo. O grupo controle (GC) foi constituído por 30 pacientes, sem doenças, submetidas a parto cesáreo por indicaçäo obstétrica. As variáveis histológicas selecionadas para estudo foram: padräo inalterado, modificaçöes fisiológicas, desorganização da camada média, alteraçöes hiperplásicas, necrose e aterose aguda. RESULTADOS: nas pacientes com DPP associado à hipertensäo ocorreu uma predominância significativa de desorganizaçäo da camada média, detectada em 50 por cento das pacientes, e de alteraçöes hiperplásicas, em comparaçäo ao GC, ao passo que a presença de modificaçöes fisiológicas foi estatisticamente mais significante no GC. Achados como necrose e aterose aguda foram observados em menores proporçöes no G/HA, mas sem diferenças significantes entre os dois grupos. CONCLUSÖES: os achados histológicos vasculares predominantes em grávidas com diagnóstico de DPP associado à hipertensäo foram desorganizaçäo da camada média e alteraçöes hiperplásicas. A presença do padräo patológico foi significativamente maior no G/HA, sendo o mais prevalente a desorganizaçäo da camada média. Houve predomínio do padräo normal, isto é, modificaçöes fisiológicas no GC

ABSTRACT

The clinical aspects and anatomopathological patterns of 150 postmenopausal women were studied using the progestogen challenge test. An endometrial biopsy was obtained and submitted to the progestogen test. A histopathological analysis of the uterine mucosa from women with a positive progestogen test revealed that the endometrium was active in 44 percent of cases and atrophic or inactive in 56 percent. In contrast, among women with a negative response, the endometrium was atrophic in 94 percent of cases and active in 6 percent. Analysis of clinical aspects did not show significant differences between groups in terms of age; age at menarche and at menopause; fasting blood glucose levels; or body mass. However, postmenopausal time was significantly shorter for women with a positive test, with a correlation between postmenopausal time of one to two years and test positivity. The progestogen challenge test for the detection of atrophic endometrium presented 78.57 percent sensitivity, 77.05 percent specificity, 44 percent positive predictive value, and 94 percent negative predictive value. Thus, when negative, the test is highly valuable, indicating the presence of atrophic endometrium in 94 percent of cases. False-negative results occurred in only 6 percent of the subjects, with no case of hyperplasia detected. However, when the response to the test was positive, the endometrium was atrophic in 56 percent of the cases. We suggest that, in order to avoid invasive procedures, the progestogen challenge test be combined with other methods such as transvaginal ultrasonography.
