Video-assisted right basal segmentectomy was successfully performed on a 72-year-old man with an anomalous pulmonary artery. Multidetector row angiography showed the A7 branch arising from the right main pulmonary artery proximal to the branches of the superior trunks, lying under the middle bronchus, and reaching segment S7. Metastatic tumor (diameter 7 mm) was identified in the periphery of this vessel. This anomaly appears to be rare but seems also to be easily overlooked and could cause serious vessel injury even for video-assisted thoracoscopic right lower lobectomy.
对一名患有异常肺动脉的72岁男性成功实施了电视辅助右肺基底段切除术。多排探测器血管造影显示A7分支起源于右主肺动脉，位于上干分支近端，在中叶支气管下方，并延伸至S7段。在该血管周围发现了转移瘤（直径7毫米）。这种异常情况似乎很罕见，但也很容易被忽视，即使对于电视辅助胸腔镜右下叶切除术，也可能导致严重的血管损伤。
