Abstract

Purpose: To determine causes of polyhydramnios and the respective perinatal outcome.

Materials and Methods: We retrospectively analyzed cases with polyhydramnios at the Medical University Graz, Austria from 2003 – 2011. Inclusion criteria were single deepest pocket ≥ 8 cm, amniotic fluid index ≥ 25 cm, each of the latter parameters > 95th percentile or subjective impression. Etiologies, including TORCH infection, diabetes and congenital malformations, as well as perinatal outcome were evaluated.

Results: Out of 860 singleton pregnancies with polyhydramnios, 2.9 % had positive TORCH serology, 8.5 % had congenital anomalies, 19.8 % had maternal diabetes, and 68.8 % were idiopathic. The most common fetal anomalies were cardiac defects (32.9 %). Elective caesarean sections were more common in the groups with malformations and maternal diabetes. Low birth weight combined with severe polyhydramnios or maternal diabetes was associated with malformations.

Conclusion: Diagnosis of polyhydramnios should prompt glucose-tolerance testing, detailed sonography including fetal echocardiography, and TORCH serology. Especially pregnancies with polyhydramnios and small fetuses as well as those with maternal diabetes should be carefully evaluated for malformations.

Zusammenfassung

Ziel: Ein Polyhydramnion tritt in 1 – 2 % aller Schwangerschaften auf. Ziel der vorliegenden Studie ist die Ermittlung repräsentativer Zahlen über mögliche Ursachen und das perinatale Outcome betroffener Schwangerschaften.

Material und Methoden: In einer retrospektiven Analyse wurden Einlingsschwangerschaften mit einem Polyhydramnion, welche zwischen 2003 und 2011 an der Universitätsklinik für Frauenheilkunde und Geburtshilfe in Graz betreut wurden, evaluiert. Ein Polyhydramnion wurde definiert als „single deepest pocket“ (SDP) ≥ 8 cm, „amniotic fluid index“ (AFI) ≥ 25 cm, das Überschreiten der 95. Perzentile des entsprechenden Gestationsalters einer der beiden Parameter oder der subjektive Eindruck. Zielparameter waren die zugrundeliegende Ätiologie, im speziellen eine Infektion mit Toxoplasmose, anderen Viren, Röteln, Cytomegalovirus oder dem Herpes simplex Virus (TORCH), ein mütterlicher Diabetes oder angeborene fetale Fehlbildungen sowie das perinatale Outcome.

Ergebnisse: Im untersuchten Zeitintervall trat bei 973 Einlingsschwangerschaften ein Polyhydramnion auf. Bei 2,9 % der Patientinnen lag eine positive TORCH-Serologie vor, in 8,5 % konnte prä-, oder postnatal eine strukturelle Anomalie oder eine Aneuploidie festgestellt werden. 19,8 % waren mit einem mütterlichen Diabetes assoziiert und 68,8 % der Fälle waren idiopathisch. Die primäre Sectiorate war höher in den Gruppen mit fetalen Fehlbildungen und mütterlichem Diabetes. Niedriges Geburtsgewicht mit ausgeprägtem Polyhydramnion und mütterlicher Diabetes waren häufiger mit fetalen Fehlbildungen assoziiert.

Schlussfolgerung: Die diagnostische Abklärung bei vorliegendem Polyhydramnion, sollte ein Diabetesscreening, eine detaillierte Ultraschalluntersuchung mit Echokardiografie, sowie eine TORCH-Serologie umfassen. Ist das Polyhydramnion mit einem kleinen Kind oder mütterlichem Diabetes assoziiert sollte ein sorgfältiger Fehlbildungsausschluss erfolgen.
