          TERMINOLOGY

          • Abbreviations

            • Left pulmonary artery sling (LPAS)
          • Definitions

            • Left pulmonary artery (PA) originates from posterior aspect of right PA, forming "sling" around distal trachea as it courses toward left between trachea and esophagus
            • Also: Anomalous origin of left pulmonary artery
            • Carina: Uppermost dichotomy site of trachea (usually T4-T5)
            • Pseudocarina: Tracheal dichotomy to left main bronchus and bridging bronchus (T5-T7)
