CASE REPoRT The patient was a 4l-year-old white girl. She had been born to a diabetic mother by cesarean section after seven months of gestation. The patient's birth weight was 3,175 gm (7 lb). She presented with mild respiratory distress, and a hypoplastic right lung was diagnosed clinically and radiologically. A heart murmur had been noticed when the patient was 27 months of age, and she was referred for a cardiac evaluation. The family history was noncontributory for congenital or rheumatic heart disease. The patient had no cyanosis or clubbing. Pulses were equal in all extremities, and the blood pressure was 90/40 mm Hg. The trachea was shifted to the right side. The chest was asymmetric, with flattening of the wall on !:lJ,e right side of the chest. The cardiac impulse was situated in

line. The first and second heart sounds were normal. A
continuous murmur was heard along the right sternal border. Breath sounds were diminished over the wall of the right side of the chest. The patient's electrocardiogram revealed right axis deviation and mild ventricular hypertrophy. A chest roentgenogram and barium swallow suggested hypoplastic right lung and a cardiac silhouette located in the right side of the chest (Fig 1). The clinical impression was patent ductus arteriosus with hypoplastic right lung. Cardiac catheterization and angiographie studies revealed patent ductus arteriosus which was entered from the pulmonary artery. The right pulmonary artery appeared hypoplastic and the left normal. The presence of the patent ductus arteriosus was further demonstrated by left ventricular cineangiogram (Fig 2). The right upper pulmonary vein entered the right atrium. Arterial oxygen saturation was 92 volumes percent, suggesting mild intrapulmonary shunting. Pulmonary arterial pressure was mildly elevated to 41/26 mm Hg. The patent ductus arteriosus was approached via a median sternotomy. The pericardium was opened, and ductal closure was achieved with two ligatures of heavy silk. The postoperative course was uneventful DISCUSSION
Fifty-nine . cases of patent ductus arteriosus were found on Schechter'sl review of 414 patients with congenital subtractive bronchopulmonic maHonnation. Six of this group underwent ductal closure. The usual surviving patient with an absent lung and persistent patent ductus arteriosus has the left lung absent and the patent ductus on the left. Closure of such a patent ductus is easily achieved through the left side of the chest. 2 ,4 In two patients with absent left lung and right-sided patent ductus arteriosus, the patent ductus was approached via bilateral anterior thoracotomy and via right anterolateral thoracotomy by Swan et aI. 5 . The feasibility and safety of an approach to the patent ductus arteriosus via a median sternotomy was demonstrated both by Kirklin and Silvera and by McGoon a in their experience with patients undergoing open-heart surgery. An approach via median sternotomy was chosen for our patient in order to avoid opening the left pleural space and compressing the single left lung during the ductal closure. Closure of a patent ductus arteriosus is indicated in the presence of a single pulmonary artery. This is especially important if there is pulmonary hypertension, as in our patient. The overloaded pulmonary circuit is exposed to the risk of pulmonary vascular disease if the left-to-right shunt is allowed to persist.

We present herein the first reported case of recurrent nocardiosis involving a sequestered area of lung. CASEREroRT On a routine chest x-ray film in October 1972, a 26-yearold asymptomatic white man was found to have multiple large pulmonary nodules in the right lower lobe (Fig 1A).

He had served overseas tours in Europe and southeast Asia, but had been in the United States for one year prior to this chest x-ray examination. Examination of the lungs revealed localized 8ne rAles over the right lower lung field posteriorly, along with percussion dullness.
