Association of Membrane Thickness, Histopathologic Findings and Premature Rupture of the Membranes / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: The aim of our study was to compare the thickness and histopathologic changes in the fetal membrane between premature rupture of membranes (PROM) and intact membrane after delivery. METHODS: In a prospective study involving 31 patients who were divided into 4 groups such as or=37 weeks without PROM, and >or=37 weeks with PROM, we measured the thickness of membrane and studied the histopathologic findings in vitro by light microscopy of histological sections. RESULTS: The membrane thickness of or=37 weeks with PROM and >or=37 weeks without PROM were similar (25.6 micrometer, 26.0 micrometer). But the membrane thickness of >or=37 weeks with/without PROM was significantly thinner (25.8 micrometer) compared with that (38.9 micrometer) of or=37 weeks was statistically significant. The histopathologic change of PROM positive group was prominent as amnionitis. Further evaluation will be needed about the relationship between membrane thickness and PROM.
