Abstract

PIP: This is the 1st case report of a ductal closure occurring during fetal growth. The case was a spontaneous delivery in cephalic presentation from a 31-year-old gravida 3, para 3 Black woman who had been treated with isoniazid and spreptomycin up to 2 months before her delivery. Gestational age was 37 weeks when the fetus was delivered weighing 3.15 kgm. The cord had been wrapped around the fetus's neck, and breathing was delayed 2 minutes. In the nursery, the baby's general condition was poor, and congestive heart failure was diagnosed. The newborn had trieuspid insufficiency, severe heart failure, and acidosis at birth. These disappeared the next day. Hemodynamic studies when the baby was 4 hours old showed a large cone-shaped ductus arteriousus extending from the pulmonary artery but ending blindly at the aortic end.
