Objectives: In low-risk pregnancies, the management of oligohydramnios is not clear. The aim of this study was to compare maternal and neonatal outcomes in cases of isolated oligohydramnios randomised to either induction of labour or expectant management., Methods: 87 women pregnant beyond 40 completed weeks were asked to participate in the study. Fifty-four accepted and were randomised at 288 days of pregnancy. Twenty-six were randomised to expectant management and 28 to induction of labour. The primary maternal outcome was the mode of delivery and the primary neonatal outcomes were cord blood pH and Apgar score at delivery., Results: No significant differences were found for any important maternal or neonatal outcome., Conclusion: Based on these results, the decisions about management could be individualised. Even though the number of patients included was small, these results are well in concordance with others., (Copyright (c) 2005 S. Karger AG, Basel.)

Objective. To describe the establishment of the fetoscopic guided laser occlusion (FLOC) technique for treatment of twin-to-twin transfusion syndrome (TTTS) and the initial results in a Swedish national center. Design. Retrospective, descriptive study. Setting. Tertiary level university hospital. Population. All referred and treated cases suffering significant TTTS. Methods. The present study includes all cases of FLOC for TTTS at the Center of Fetal Medicine at Karolinska University Hospital, Stockholm, Sweden from October 2001 until December 2009. Patients were referred from all over Sweden and a few from other Nordic countries. The patients were evaluated with ultrasound examination between gestational ages of 18 and 26 weeks. Data from patients were extracted from our electronic medical record system and, in addition, families were contacted and medical records requested from referring hospitals. Main outcome measures. Pregnancies with one or more surviving infants after FLOC treatment categorized according to stage of TTTS. Results. In 75% of pregnancies, one or more infant was born alive. At stage I, both infants survived in one pregnancy and one survived in the second. There was no significant difference between cases at stage II or III, i.e. 73 vs. 78% of pregnancies resulted in one or more surviving infant. At stage IV, 66% of pregnancies ended with one or more surviving infant. Conclusions. Treatment of TTTS is feasible in a rather small country like Sweden, with comparable results to other centers. There are strong arguments for centralization and further improvement of this kind of highly specialized treatment. [ABSTRACT FROM AUTHOR]

Aim: To determine infant survival and neonatal outcome after fetoscopic laser treatment of twin-to-twin transfusion syndrome (TTTS). Results: In 53/71(75%) laser-treated TTTS cases, at least one twin was liveborn and in 42/71(59%) cases at least one twin survived infancy. Fetal survival did not differ between donors [41/71(58%)] and recipients [46/71(65%), P=0.36]. Among liveborns, infant survival was 29/41(71%) in donors and 36/46(78%) in recipients (P=0.12). Infant survival did not correlate to maternal characteristics (age, BMI, smoking or parity), gestational age at treatment or severity of TTTS (Quintero stage). No TTTS infant born before 25 weeks of gestation survived the first week. Among the 87 infant survivors, 26 (30%) had an Apgar score <7 at 5 min, 47 (54%) developed respiratory distress syndrome, 10 (11%) showed signs of severe brain damage, nine (10%) renal failure, eight (9%) bronchopulmonary dysplasia, and five (6%) infants developed retinopathy of prematurity ≥stage 3. There was no significant difference in neonatal morbidity between recipients and donors. Conclusions: Fetal survival after laser treatment was comparable to that reported by other international centers. There was no significant difference in survival or neonatal morbidity between donors and recipients. Major neonatal morbidity was common, and combined with extremely preterm delivery the prognosis of TTTS is poor. [ABSTRACT FROM AUTHOR]
