title: Pelvic exsanguination following umbilical artery catheterization in neonates.
abstract: Umbilical artery catheterization in 400 newborns was followed by umbilical or hypogastric artery perforation with massive extra- and intraperitoneal bleeding in 7 infants. Common predisposing factors were multiple attempts and insertion against resistance. A characteristic clinical picture developed, including hypotension, abdominal distention, and lower abdominal wall induration and ecchymosis, often extending into the genitalia and upper thighs, with absent femoral pulses. Treatment is immediate transfusion and bilateral umbilical and hypogastric artery ligation. One of seven patients survived.
