title: [Bronchogenic carcinoma associated with right aortic arch and postaortic left brachiocephalic vein--report of a case].
abstract: 61-year-old male was admitted to our hospital for surgical treatment of bronchogenic squamous cell carcinoma arising from left B8. The patient had right aortic arch with aberrant left subclavian artery and postaortic left brachiocephalic vein. Intraoperatively, left ligamentum arteriorsus forming vascular ring between the left subclavian artery and the pulmonary artery was found, however the ligamentum arteriorsus was not divided because no symptom of esophago-tracheal compression was observed. The left brachiocephalic vein was located between the ascending aorta and the arterial ligament. The lower lobe of the left lung was resected, and lymph nodes in the left side of the mediastinum were dissected easily because the aortic arch was positioned on the other side. Preoperative assessment of the type of branching and the course of arteries and veins is important for safe operation.
