Zusammenfassung
Studienziel: Die feto-amniale Shuntanlage stellt eine ultraschallgezielte therapeutische Intervention zur dauerhaften Entlastung intrakavitärer Flüssigkeitsansammlungen bei schwer betroffenen Feten mit ungünstiger Prognose dar. Da das relativ hohe Eingriffsrisiko dem potenziellen Nutzen gegenübergestellt werden muss, evaluieren wir die Wertigkeit der verschiedenen Indikationen, die Komplikationsrate und die Zeitspanne der korrekten Positionierung der Shuntanlage. Patienten und Methode: Aussendung eines Fragebogens über feto-amniale Shuntanlagen von 1993 bis 2001 an alle deutschsprachigen Stufe-III-Zentren. An 6 Stufe-III-Zentren erfolgten 47 feto-amniale Shuntanlagen bei 30 Schwangerschaften (18 Feten mit Megavesica [3 davon mit urinösem Ascites], 8 Feten mit Hydrothorax, 2 Feten mit Hydronephrose, 1 Fetus mit zystisch adenomatoider Malformation der Lunge [CAM I], 1 Fetus mit Ovarialzyste). Ergebnisse: Das mediane Schwangerschaftsalter zum Zeitpunkt der Shuntanlage betrug 23,5 (range 16 - 33) Wochen, zum Zeitpunkt der Geburt 35 (range 23 - 41) Wochen. Die mediane Shuntfunktion betrug 19 (range 0 - 170) Tage. Insgesamt haben 18 von 30 Feten (60 %) von der feto-amnialen Shuntanlage profitiert. Schlussfolgerung: Die bestmögliche Selektion der Schwangerschaften, die von einer feto-amnialen Shuntanlage profitieren, ist notwendig. Grunderkrankung, Schwere und Progredienz der Störung sind hierbei die ausschlaggebenden Kriterien.
Abstract
Aim: Foeto-amniotic shunting is an ultrasound-guided, therapeutic intervention for drainage of persistent intracavital fluid retention in severely affected foetuses with a high risk of mortality. In order to weigh up the comparatively high risk of intervention against the possible benefit, we evaluated the value of different indications, the complication rate and the time span of drains in situ. Patients and Methods: We made a survey of all level III ultrasound centres of German-speaking countries from 1993 to 2001. Six level III centres returned the questionnaire: forty-seven foeto-amniotic shunting procedures were performed in 30 foetuses [megacystis in 18 foetuses (three of these with urinary ascites), hydrothorax in eight foetuses, hydronephrosis in two foetuses, cystic adenomatoid malformation of the lung in one foetus, ovarian cyst in one foetus]. Results: The median gestational age at time of shunting was 23.5 (range 16 - 33) weeks, at time of delivery 35 (range 23 - 41) weeks. The median time span of drains in situ was 19 (range 0 - 170) days. Altogether 18 of 30 foetuses (60 %) had a benefit of foeto-amniotic shunting. Conclusion: The best possible selection of pregnancies which might profit from foeto-amniotic shunting is required. The decisive criteria are the underlying defect as well as the severity and progression of the disorder.
