Collateral ventilation in "Intralobar Pulmonary Sequestration"

Report of a Case

¹ Departments of Surgery, Mount Zion Hospital and St. Mary's Hospital

Though one cannot draw firm conclusions from a single case study, the absence of inflammation in this case of "intralobar sequestration" has permitted a clear delineation of the pathologic conditions present, which in turn support our inferences.

The role of collateral ventilation in producing emphysema with its concomitant air-trapping is apparent in this case of the "sequestration" complex.

Reference has been made to previously reported cases of simple bronchial cystic disease with associated collateral ventilation, air-trapping, and emphysema, but without systemic arterialization.

The similar features of the "sequestration" complex and bronchial cystic disease suggest that they represent variants of single process. Perhaps a preferable designation for the complex would be intralobar bronchial cystic disease, with or without systemic arterialization, as the case may be.
