Bilateral congenital eventration of the diaphragms: successful surgical management.
Bilateral congenital eventration of the diaphragms is a relatively rare occurrence, associated with an almost uniform mortality. We recently have had experience with three patients who underwent successful treatment of this anomaly. Each patient presented as a newborn with severe respiratory insufficiency. One had had a sibling who died shortly after birth with a congenital diaphragmatic hernia. One infant had associated respiratory distress syndrome. PA and lateral chest roentgenograms demonstrated the anomaly in each patient. In two, the use of ultrasound clearly demonstrated the presence of attenuated diaphragms and paradoxical motion. Each infant underwent transabdominal bilateral diaphragmatic plication, reinforced with transversus abdominis muscle, within the first 2 weeks of life. Two infants showed prompt improvement in arterial blood gases and were extubated following the operation. The infant with respiratory distress syndrome required a tracheostomy for continued mechanical ventilation. This infant developed a recurrent eventration of the left diaphragm 6 months after the initial operation and has undergone a secondary plication with clinical improvement. Unlike unilateral eventration, bilateral eventration of the diaphragms is associated with persistent and significant respiratory symptoms. Surgical plication should be performed urgently in all of these patients, before chronic pulmonary changes occur.
