A 64-year-old man with chronic atrial fibrillation was referred to our hospital for resection of a biopsy-proven adenocarcinoma of the right lung. A preoperative coronary angiogram demonstrated large, tortuous collateral vessels arising from the proximal right (Figure 1) and left circumflex (Figure 2) coronary arteries. These vessels supplied the right lung. The native coronary arteries were moderately diseased. A right ventriculogram showed no visualization of the right pulmonary artery (Figure 3). A computed tomogram of the chest also showed that the right pulmonary artery was absent (Figure 4). An aortogram showed no arterial supply to the right lung other than that from the coronary arteries. The patient underwent a right pneumonectomy and did well thereafter.
