Abstract
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 7.8mm 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 (7.8mm in diameter) and is an extremely rare variant, passing posterior to the RMB and draining into the LA.
