Pulmonary artery sling (PAS) is a rare congenital vascular anomaly that results when the left pulmonary artery arises from the right pulmonary artery. There is little relevant literature on lobectomy for the treatment of lung cancer in patients with PAS, and the prognosis is unknown.
A 54-year-old asymptomatic man was found to have a nodule on the left lower lobe of the lung, which measured 2.5 cm. The patient also had PAS. Three-dimensional computed tomography angiography confirmed that the left pulmonary artery arose from the right pulmonary artery and passed between the main trachea and the esophagus toward the left thorax. No obvious contraindication was found in the preoperative examination, and the patient successfully underwent lobectomy of the left lower lobe by video-assisted thoracoscopic surgery. Histological examination of the lesion revealed invasive adenocarcinoma. The postoperative course was uneventful, and no complications occurred in the subsequent 3 years of follow-up.
Lobectomy in a lung cancer patient with PAS did not increase perioperative risk and had no significant effect on prognosis.
肺动脉吊带（PAS）是一种罕见的先天性血管异常，由左肺动脉起源于右肺动脉引起。关于肺动脉吊带患者行肺癌肺叶切除术的相关文献较少，且预后未知。
一名54岁无症状男性被发现左肺下叶有一个2.5厘米的结节。该患者还患有肺动脉吊带。三维计算机断层扫描血管造影证实左肺动脉起源于右肺动脉，并在主气管和食管之间向左胸走行。术前检查未发现明显禁忌证，患者通过电视辅助胸腔镜手术成功接受了左肺下叶切除术。病变组织学检查显示为浸润性腺癌。术后过程顺利，在随后3年的随访中未发生并发症。
肺动脉吊带患者行肺癌肺叶切除术不会增加围手术期风险，对预后也无显著影响。
