Premature newborn now 1 month old with a patent ductus arteriosus

CXR of PDA clip on left mainstem bronchus
Preoperative CXR AP (above left) shows mild cardiomegaly and increased pulmonary vascularity. Postoperative CXR AP (above right) shows interval placement of a rather large clip on the ductus arteriosus. There is interval development of complete collapse of the left lung. CXR AP obtained after remove of the clip (below) shows interval reexpansion of the left lung.

The diagnosis was accidental clipping of the left mainstem bronchus along with the patent ductus arteriosus.
