A lung granuloma with partial anomalous pulmonary venous connection and bronchial atresia

Partial anomalous pulmonary venous connection and a tracheal bronchus associated with lung cancer in the same lobe: classification of partial anomalous pulmonary venous connection in lung resection

A 73-year-old man with primary lung adenocarcinoma (StageIA3), which was solid nodule in the posterior segment, was simultaneously diagnosed as having partial anomalous pulmonary venous connection (PAPVC) and a tracheal bronchus in the same lobe on preoperative chest computed tomography. Right upper lobectomy was performed as the definitive treatment for both the lung cancer and the PAPVC. The superior pulmonary vein connected to the proximal superior vena cava and the pulmonary artery to the apical segment diverged at the proximal portion of the right pulmonary artery trunk along with the tracheal bronchus. The patient's pulmonary arterial pressure improved after lobectomy. The patient is living well without recurrence of lung cancer 6 months after surgery. In conclusion, it is important to confirm the presence of anomalous pulmonary vein drainage to prevent the lethal change of pulmonary-systemic blood flow. Based on the classification of PAPVC proposed, surgical plan should be considered carefully.

Management of partial anomalous pulmonary venous connections in patients requiring pulmonary resection: a case report and systematic review

Partial anomalous pulmonary venous connections (PAPVCs) are rare congenital anomalies that are frequently asymptomatic in adults. When PAPVCs are encountered in the patient requiring pulmonary resection, improper management can result in fulminant right-heart failure and death. In this report, we note our management of a 70-year-old male who presented with a right upper lobe ground-glass opacity (GGO) and a PAPVC. We also provide a systematic review of all contemporary reports and provide an algorithm for PAPVC management in the adult patient requiring pulmonary resection.
