Abstract

Pulmonary vein wedge angiography was applied to 25 patients ranging in age from 4 months to 16 years. The indications for this technique include (1) determination of the presence or absence of central (intrapericardial or mediastinal) pulmonary arteries in patients with pulmonary atresia where standard anterograde injections of contrast medium do not demonstrate these, (2) determination of the patency and caliber of a nonvisualized pulmonary artery when there is distal "occlusion" by a systemic-to-pulmonary artery anastomosis, (3) determination of the patency and caliber of a nonvisualized pulmonary artery when previous pulmonary arterial banding has led to acquired pulmonary artery atresia, and (4) determination of the presence of a mediastinal pulmonary artery in patients with so-called isolated congenital unilateral absence of a pulmonary artery. Surgical correlates to the interpretation of pulmonary vein wedge angiograms are provided in 18 patients. The present data suggest that pulmonary vein wedge angiography is a safe technique that provides considerable information about (1) the caliber of the parenchymal pulmonary arteries, (2) their sizes at the hilum of the lung, and (3) the presence or absence of a mediastinal confluence of pulmonary arteries. This technique may also complement those anatomic findings derived from anterograde injection of contrast material in patients with pulmonary atresia of a congenital or acquired nature.
