To evaluate the multi detector computed tomographic (CT) depiction of middle lobe vein variation of the right pulmonary vein and create a diagram for cardiologist and cardiovascular surgeons.
According to hospital records, between January 2009 and April 2010, 314 consecutive patients underwent pulmonary CT angiography (CTPA) and coronary CT angiography. The CT films from these patients were retrospectively analyzed.
Under normal conditions, the middle pulmonary vein (MPV) drains into the left atrium either by the "direct" or "indirect" route. Direct (37 patients, 11.8%) drainage means that the MPV does not drain into the upper or lower pulmonary veins but instead drains directly into the right pulmonary vein system. In contrast, indirect (276 patients, 87.9%) drainage occurs when the MPV drains into the upper or lower pulmonary veins. In this study, 12 different variations in drainage patterns were found.
Increasing the number of patients may have led to the identification of additional variants. However, clinically important variations are rarely seen. Correct mapping of the MPV is very important for cardiologists and for surgeons in order to provide the best treatment and avoid complications.
评估多探测器计算机断层扫描（CT）对右肺静脉中叶静脉变异的描述，并为心脏病专家和心血管外科医生创建一个示意图。
根据医院记录，2009 年 1 月至 2010 年 4 月期间，314 例连续患者接受了肺动脉 CT 血管造影（CTPA）和冠状动脉 CT 血管造影。对这些患者的 CT 胶片进行了回顾性分析。
在正常情况下，中叶静脉（MPV）通过“直接”或“间接”途径排入左心房。直接（37 例，11.8%）引流意味着 MPV 不排入上或下肺静脉，而是直接排入右肺静脉系统。相比之下，间接（276 例，87.9%）引流是指 MPV 排入上或下肺静脉。在这项研究中，发现了 12 种不同的引流模式变化。
增加患者数量可能会导致发现更多的变异。然而，临床上重要的变异很少见。正确映射 MPV 对心脏病专家和外科医生非常重要，以便提供最佳治疗并避免并发症。
