We present two cases of individual pulmonary vein atresia without vestige of an involved pulmonary vein. On CT, we noted the absence or interruption of normal pulmonary venous structures, and the presence of abnormal vascular structures that represented collaterals for the involved lung parenchyma. On angiography, the atretic pulmonary vein was found to drain into the other ipsilateral pulmonary veins through the collaterals.

In this review, the clinical features and management of less commonly encountered cyanotic cardiac lesions are reviewed. Pathophysiology, clinical features, laboratory studies and management are discussed. The clinical and non-invasive laboratory features of these cardiac defects are sufficiently characteristic for the diagnosis and invasive cardiac catheterization and angiographic studies are not routinely required. Such studies may be needed either to define features that could not be clearly defined by non-invasive studies or prior to performing trans-catheter interventions. Surgical correction or effective palliation is possible at relatively low risk. But, residual defects, some requiring repeat catheter or surgical intervention, may be seen in a significant percentage of patients and consequently, continued follow-up after surgery is recommended.
