Triangular Defect (Congenital Diaphragmatic Hernia)

atno_2_n.jpg: Operative findings: View from the opened abdominal cavity on the left diaphragm. The swab displaces the spleen to the midline. There is a posteriorly situated triangular defect. The diaphragm is anteriorly intact. The left lobe of the liver is also tilted to the midline. The diagnosis is a left pleuroperitoneal Bochdalek's diaphragmatic hernia of the lumbocostal trigonum without hernia sac in a 2.9-year-old boy. The herniated abdominal content is reduced by a few collapsed intestinal loops at the bottom of the figure. atno_3a_n.jpg: Analogous case of a 12.9-year-old girl with a congenital diaphragmatic hernia without a hernia sac. The left thoracic cavity is visible, and a part of the left kidney marks the border of the opening on the right side of the picture. atno_3b_n.jpg: The residual diaphragm is well developed with recognizable fibers in the same girl.
