Aberrant mediastinal basal pulmonary artery encountered at anatomical lung resection: A case report and review of the literature.

ABSTRACT:

Introduction

Abnormal branching of the pulmonary artery is often encountered in anatomical lung resection, which can potentially result in accidental vessel injury with life-threatening bleeding or extra lung resection. The mediastinal basal pulmonary artery (Arteria Praebronchialis, AP) is a very rare but potentially critical variant.

Presentation of case

We present the case of a patient with lung cancer accompanied by the left basal segmental pulmonary artery, independent A^8a+9, which was liable to be injured during lower lobectomy with poor interlobar fissure development. This variation was preoperatively recognized using three-dimensional contrast-enhanced computed tomography (3D-CECT) angiography, and vessel injury was avoided.
