Pulmonary sequestration complicated by anomalies of pulmonary venous return.
Five anomalies of pulmonary venous drainage were seen among 12 children operated for lung sequestration. In two children, venous drainage from the sequestrated lobe and the rest of the right lung was via a single channel into the inferior vena cava ("scimitar syndrome"). In one of these children, the sequestrated lobe was resected and repair of the scimitar syndrome was delayed; in the second patient, the anomalous pulmonary venous drainage was not recognized preoperatively and the vein was ligated, resulting in acute hemorrhagic infarction of the right lung and death of the patient. Three patients had less severe anomalies of pulmonary venous drainage. We recommend very careful evaluation of patients with lung sequestration with special reference to pulmonary venous drainage.
