Abstract
Spontaneous hematoma of the umbilical cord is a rare, unpreventable, and dramatic event mainly due to a disruption of the vascular wall, often resulting in adverse perinatal outcome. We describe a case of a term fetus with acute hemorrhage in the cord occurred intrapartum during spontaneous vaginal delivery. No iatrogenic factors were involved because no drugs, obstetric instruments, or procedures were applied. Umbilical hematoma probably developed in a time frame of 90 seconds, when the electronic fetal monitoring tracing detected a loss of fetal heart rate. At birth, the baby was in serious conditions with a low Apgar score (always 3 at 1, 5, and 10 minutes) and severe mixed acidosis. He was intubated, was ventilated, and underwent therapeutic hypothermia. Although all standard emergency procedures had been immediately applied, hypoxic-ischemic encephalopathy ensued within 24 hours postnatal. Placental examination revealed in the cord disruption of the elastic fibers in the vessels walls. Moreover, myofibroblasts in the Wharton's jelly appeared reduced in number and blunted, instead of their usual stellate shape. Chorioamnionitis but no funisitis was also present.Clinical follow-up of the child, aged 4 years, showed spastic t...Continue Reading
