Two Cases of Anomalous V² Bronchus of the Pulmonary Vein in the Right Upper Lobe

Abstract

The usefulness of combined 3-D reconstruction imaging using CT angiography (CTA) and CT bronchography (CTB) data for the preoperative assessment of lung cancer was studied. Abnormalities or variations in pulmonary blood vessels and bronchi could be identified. We report 2 cases of lung cancer in which anomalous V² branches were clearly depicted by this method ; in one case the anomalous branch travelled dorsally to the main bronchus and, in the other, it travelled to the intermediate bronchus. The accurate preoperative assessment of pulmonary blood vessels and branching bronchi is necessary for doing the surgery safely. Combined 3-D reconstruction imaging using CTA and CTB data serves this purpose well.
