We herein describe a patient with segmental pulmonary artery transection after blunt trauma, which was diagnosed preoperatively by computed tomography. Bolus tracking contrast-enhanced computed tomography clearly depicted both aortic and pulmonary vasculatures. A one-step examination quickly disclosed aortic damage and injury to significant visceral organs. To the best of our knowledge, our patient appeared to be a unique case of pulmonary segmental artery transection after blunt injury, which was preoperatively diagnosed by computed tomography. Ultimately, successful surgical repair of the pulmonary artery was performed.
