The right top pulmonary vein (RTPV), a rare pulmonary vein (PV) variant draining the right upper lobe, arises independently from the right superior PV, travels posterior to the right bronchial tree and drains directly into the left atrium (LA) or another PV. We report an RTPV discovered on preoperative computed tomography (CT) scanning in a 60-y-old man who subsequently underwent prone thoracoscopic esophagectomy and subcarinal lymph node dissection. The preoperative CT scan showed an anomalous vessel 7.8 mm in diameter arising from the right upper lobe, running posterior to the right main bronchus (RMB), and draining directly into the LA. To our best knowledge, this is the largest reported RTPV (7.8 mm in diameter) and is an extremely rare variant, passing posterior to the RMB and draining into the LA.
右上肺静脉（RTPV）是一种罕见的肺静脉（PV）变异，引流右上叶，独立于右上肺静脉发出，走行于右支气管树后方，直接汇入左心房（LA）或另一肺静脉。我们报告了一名60岁男性患者，术前计算机断层扫描（CT）发现RTPV，随后接受了俯卧位胸腔镜食管切除术和隆突下淋巴结清扫术。术前CT扫描显示，一条直径7.8毫米的异常血管发自右上叶，走行于右主支气管（RMB）后方，直接汇入LA。据我们所知，这是报道中最大的RTPV（直径7.8毫米），是一种极其罕见的变异，走行于RMB后方并汇入LA。
