title: Intrapartum rupture of the falciform ligament and umbilical vein. A rare cause of hemoperitoneum in the newborn.
abstract: Intra-abdominal hemorrhage in the newborn is uncommon, but it must be considered in the first 48 hours of life in the infant with pallor, anemia, abdominal distension, and shock. The injured liver is the most common source of bleeding, with the spleen and kidney less often involved. In the case presented, the hallmarks of intra-abdominal hemorrhage were evident. Exploratory laparotomy revealed intraperitoneal bleeding emanating from the disruption of the umbilical vein and its enveloping falciform ligament. There was no other site of intra-abdominal bleeding and there were no intrinsic abnormalities of the umbilical cord or the placenta. Disruption of the intra-abdominal umbilical vein represented the sole source of intra-abdominal bleeding in this patient. The case is reported to document disruption of the intra-abdominal umbilical vein as a rare cause of neonatal hemoperitoneum.
