Background: Anatomic variation may increase the difficulty and risk of anatomic segmentectomy. The preoperative three-dimensional computed tomography bronchography and angiography (3D-CTBA) can provide a detailed model of the segmental structure, and contribute to precise and safe segmentectomy.
Case presentation: This is a case of anomalous bronchi and pulmonary vessels in the right upper posterior segment (RS2). Under the guidance of 3D-CTBA, anatomic RS2 segmentectomy was performed accurately and safely. The postoperative condition was uneventful.
Conclusions: This rare case highlights the importance of 3D-CTBA to guild accurate segmentectomy with anatomic variation.
