Video-Assisted Thoracic Surgery Lobectomy for Lung Cancer with Displaced B¹⁺²

Abstract

A 52-year-old man was diagnosed with lung adenocarcinoma in the left upper lobe (c-T1bN0M0). Preoperative bronchoscopy revealed a displaced anomalous B¹⁺² arising from the left main bronchus. Multiplanar reconstruction computed tomography showed that the displaced B¹⁺² was located behind the left main pulmonary artery, and the interlobar fissure was largely fused. Video-assisted thoracic surgery (VATS) left upper lobectomy was performed successfully. The “no-touch fissure” technique was efficient not only for avoiding accidental cutting of the displaced bronchus but also post-operative air leakage. This is the first reported case of VATS lobectomy for lung cancer associated with a displaced B¹⁺².
