Abstract
PURPOSE: The primary objective of the present study was to use CT angiography and 3D reconstruction to assess and to classify the mediastinal pulmonary basal segmental arteries. METHODS: We report a particular type of bifurcated left lower pulmonary artery, namely, the "mediastinal basal pulmonary artery" type, which is the first branch from the proximal the left pulmonary artery (LPA) between the left main bronchus (LMB) and the left superior pulmonary vein (LSPV) and proceeding directly into the lower lobe. There are many types of mediastinal basal pulmonary arteries, and these can be classified worldwide in a unified way and format, which will be beneficial for clinical records, annotation and academic exchange. RESULTS: The mediastinal basal pulmonary arteries are described either as "supernumerary" when duplicating or "displaced" when replacing the normal arterial branching pattern of the lower lobe. The displaced type is more frequent than the supernumerary type. There are 12 types of left mediastinal basilar arteries. CONCLUSION: This is the first report to categorize the mediastinal basal pulmonary artery, is the first to suggest a system for mediastinal basal pulmonary artery nomenclature, and creates simplified models for use when planning anatomical segmentectomy. Knowledge and recognition of this rare and special condition may facilitate better diagnosis and treatment of these patients.
