VATS right posterior segmentectomy with anomalous bronchi and pulmonary vessels: a case report and literature review

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 (RS(2)). Under the guidance of 3D-CTBA, anatomic RS(2) 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.
