Disruption in the flow of blood vessels is of great concern during thoracic surgery. Preoperative 3-dimensional computed tomography facilitates visualization of the exact location and course of blood vessels. The right posterior upper lobe segmental vein, known as the right top pulmonary vein (RTPV), is an anomalous vein beginning at the right upper lobe and running through the posterior surface of the intermediate bronchus. We clinically investigated 31 patients with RTPV who underwent lobectomy or total resection of the right lung in our hospital or related institutions. We classified the final destination of RTPV into four types. The RTPV flowed into the left atrium in 35.5% of cases, superior pulmonary vein in 9.7%, inferior pulmonary vein in 41.9%, and independently into V6 in 12.9%. An RTPV with a diameter ≥ 5 mm was considered a main drainage vein in S2. We should pay attention to the RTPV during right lung lobectomy.
血管血流的中断在胸外科手术中是一个非常值得关注的问题。术前的三维计算机断层扫描有助于观察血管的确切位置和走行。右上叶段静脉，即右肺上静脉（RTPV），是一种异常静脉，起始于右上叶并穿过中间支气管的后表面。我们临床调查了 31 例在我院或相关机构行 RTPV 肺叶切除术或右全肺切除术的患者。我们将 RTPV 的最终目的地分为四型。RTPV 流入左心房的占 35.5%，流入上肺静脉的占 9.7%，流入下肺静脉的占 41.9%，独立流入 V6 的占 12.9%。直径≥5mm 的 RTPV 被认为是 S2 的主要引流静脉。在右肺叶切除术中，我们应该注意 RTPV。
