A video-assisted thoracic surgical lobectomy for a lung tumour with a rare anomalous pulmonary artery.

A detailed knowledge of anomalies of the anatomical course of the pulmonary vessels is extremely important for video-assisted thoracic surgery (VATS). Inadvertent vascular ligation and dissection are catastrophic for patients undergoing lobectomy. We describe a case with a rare anomaly of the left pulmonary artery and highlight the importance of identifying the courses of pulmonary vessels for VATS lobectomy.
