The Ductus Venosus

Abstract

Background the ductus venosus (DV) is not well known in general radiology, but it plays a role in the daily work of pediatric radiologists. Consequently all general radiologists who also care for a pediatric department should be familiar with the physiological and pathological findings related to the DV. Methods: Literature research in Medline, using the keywords “ductus venosus” and “umbilical vein catheter”. Results and conclusions In the first weeks of life the DV is regularly still patent. It should be recognized as DV and not be mistaken for a pathological portosystemic shunt.The ductus venosus is the lead structure for umbilical vein catheters. Radiologists should be able to assess the correct catheter position. Radiologically important findings of an umbilical vein catheter are mainly malposition and intrahepatic extravasation. Agenesis of the DV can lead to intra- or extrahepatic compensatory portosystemic shunts, in which as well as in the case of persistent patency of the DV, there may be the necessity for radiological-interventional or surgical occlusion.

Duktus Venozus Agenezisinin Prenatal Tanısı: Olgu Serisi

“…Duktus venozus agenezisi (DVA), portal-umblikal venöz sistem ve hepatik-sistemik venöz sistem arasında olan anastomozun başarısızlığından dolayı oluşmaktadır. DVA bazı vakalarda asemptomatik seyredebilirken, kardiyak defektler, kromozom anomalileri, portokaval şantlar, portal ven agenezisi ve diğer çeşitli patolojik değişikliklerle eşlik edebilmektedir (2,3). Sonuçları fetal hidrops ve kalp yetmezliği olabilir, bu nedenle bu vakalar kötü prognozlu olup, prenatal mortalite ve gebelik terminasyon oranı bu vakalarda yüksektir (2,3).…”
