Mediastinal pulmonary artery is associated with greater artery diameter and lingular division volume.


ABSTRACT: Pulmonary vessels have numerous variation and aberrant branching patterns. Mediastinal lingular artery (MLA), the most common aberrant branch, might contribute to greater blood flow to lingular division. Hence, we investigated a correlation between lingular division volume and MLA using three-dimensional CT volumetry. We included 199 consecutive patients who underwent surveillance chest CT to detect possible malignancies in April 2015. We measured lingular division volume and cross-sectional area of lingular arteries using three-dimensional CT volumetry. MLA was identified in 58 cases (29.1%). The MLA group had significantly greater lingular division volume (median?±?quartile deviation: 378.3?±?75.5?mL vs. 330.0?±?87.5?mL; p?=?0.021) and percentage lingular division to left lung volume (19.0?±?2.62% vs. 16.6?±?2.39%; p?2; p?=?0.003). The total cross-sectional area of the lingular arteries strongly correlated to the percentage of lingular division to left lung volume (r?=?0.689, p?
