Frequency of Structural Anomalies in Fetuses With Single Umbilical Arteries: A Report of 34 Cases

Abstract

Objective: The aim of this study was to present perinatal results of cases with single umbilical artery (SUA). Material and Methods: In this study, prenatally diagnosed 34 cases with SUA were evaluated between March 2006 and January 2011. Results: The gestational age at diagnosis varied between 16 and 37 weeks. The mean maternal age was 28.1 years. Ten of the 34 fetuses had additional congenital anomalies. The incidence of SUA was higher in female fetuses than male fetuses. The incidence of major structural anomalies (29%) were found. Major anomaly rate of female was significantly higher than male. Conclusion: Single umbilical artery, can be determined before 24 weeks of gestation. Early prenatal diagnosis and management is important for karyotype analysis and postnatal results. Detailed ultrasound examination should be performed for detection of additional congenital anomalies.

Tek Umbilikal Arterli Fetuslarda Yapısal Anomalilerin Sıklığı: 34 Olgunun Sonuçları

Abstract

Amaç: Bu çalışmanın amacı, tek umbilikal arter ( TUA ) saptanan olguların perinatal sonuçlarını sunmaktır. Gereç ve Yöntem: Bu çalışmaya Mart 2006 ile Ocak 2011 tarihlari arasında TUA saptanan 34 olgu dahil edildi. Bulgular: Onaltı ile 37 gebelik haftaları arasında tanı konuldu. Ortalama maternal yaş 28.1 yıl olarak bulundu. On fetusta ek anomali saptandı. TUA insidansı kız fetuslarda erkek fetuslardan daha yüksek idi. Majör yapısal anomali insidansı % 29 bulundu. Majör anomali insidansı kız fetuslarda erkek fetuslardan daha yüksekti. Sonuç: TUA, gebeliğin 24. haftasından önce tespit edilebilir. Erken prenatal tanı ve yönetim karyotip analizi ve postnatal sonuçlar için önemlidir. Detaylı ultrasonografi incelemesi ilave konjenital anomalilerin tespiti için yapılmalıdır.
