Abstract
We report two cases of an anomalous pulmonary vein with right V6 flow in the superior pulmonary vein. Case 1: A 70-year-old man presented with a complaint of right chest pain. Chest computed tomography revealed two nodules in the upper and lower lobes of the right lung. Since malignancy could not be ruled out, the tumors were resected. Pre-operative three-dimensional computed tomographic angiography (3D-CT angiography) showed an anomalous pulmonary vein with right V6 flow in the superior pulmonary vein. We performed a wedge resection in the right upper lobe and right lower lobectomy. Case 2: A 65-year-old man was found to have an abnormal shadow in the right middle lobe during post-operative follow-up for colon cancer. Pre-operative 3D-CT angiography showed right V6 flow in the superior pulmonary vein. A complete understanding of the anatomic features of the pulmonary vascular branch prior to surgery is essential for safe and accurate pulmonary operations.
