- Abstract
Purpose: To safely perform lymphadenectomy in the sub-aortic arch area during esophagectomy for esophageal cancer, we investigated the spatial relationships between the bronchial arteries (BAs) and the left recurrent laryngeal nerve (LRLN).Methods: For this macro-anatomical study, 72 cadavers were used.Results: Of the 195 dissected BAs, 15 (7.7%) arteries ran dorsally across the LRLN. Such a running pattern of the BA was found in 15 (20.8%) of the 72 cadavers. Fourteen (93.3%) of the 15 arteries ran anteriorly along the left side of the esophagus, and 13 (86.7%) passed further to the lateral side of the left main bronchus to reach the ventral surface of the tracheobronchus; we named this running pattern “Type III”. Of the 51 arteries with the Type III pattern, 25.5% ran across the dorsal side of the LRLN.Conclusion: Approximately 20% of the cadavers had BAs running dorsally to the LRLN in the sub-aortic arch area. Most of these arteries had the Type III pattern. One-quarter of the BAs with the Type III pattern showed this running pattern. Care must be practiced to safely perform lymphadenectomy for esophageal cancer in patients with Type III BAs.
