A case of intralobar sequestration of the lung associated with an abnormal pulmonary artery

A Theory of the Origin of Intralobar Sequestration of Lung

“…In five of the seven cases the pulmonary artery to the lower lobe on the side of the lesion was, at operation, found to be greatly reduced in size. This has been noted previously by McDowell, Robb, Hinds, and Nicks (1951), by Cole and others (1951), by Findlay and Maier (1951), and by McDowell and others (1955). The other finding, in the specimens examined post-operatively, was that the lesions in the lung and the systemic artery were very closely related in their distribution in all cases.…”

Two Cases of Intralobar Sequestration of the Lung

“…This composite picture conforms in every respect -with the case previously recorded from Green Lane Hospital (McDowell et al, 1951), and may perhaps be taken as a pattern for the recognition of the con--dition of sequestration following the establishment of :a communication with the normal bronchial tree. The picture is that of a semi-cystic mass situated typically in the postero-medial aspect of the hemithorax, susceptible to sudden changes in bulk related to partial evacuation of its contents or the trapping of air.…”

“…In the present cases, as well as in the earlier one from Green Lane Hospital (McDowell, Robb, Hinds, and Nicks, 1951), iodized oil injected into the anomalous vessel drained out of the pulmonary vein, and radiographs taken of the specimen after injection of the oil into the anomalous vessels showed free communication between it and the inferior pulmonary vein. Most authors agree that the venous return is through the pulmonary vein.…”

Intralobar Pulmonary Sequestration

“…8 Although the condition may be suspected, exact preoperative diagnosis is not often possible. Productive cough, respiratory embarrassment, hemoptysis, and asthma may also be presenting complaints.…”
