Pulmonary venous compression caused by a large lung mass was diagnosed in a 50-year-old female with metastatic renal cell carcinoma. The pulmonary venous flow pattern on Doppler revealed high flow velocity as well as the unusual finding of continued antegrade flow throughout the cardiac cycle (without reversal during atrial contraction). Extracardiac tumors can compress pulmonary veins, mimicking pulmonary vein stenosis. This may cause dyspnea due to elevated pulmonary venous pressures. This report describes an unusual pulmonary vein blood flow pattern in a patient with lung metastases.
一名50岁转移性肾细胞癌女性患者被诊断为因巨大肺部肿块导致肺静脉受压。多普勒显示肺静脉血流模式呈现高流速，以及在整个心动周期中持续正向血流这一异常发现（心房收缩期无血流逆转）。心外肿瘤可压迫肺静脉，酷似肺静脉狭窄。这可能因肺静脉压力升高导致呼吸困难。本报告描述了一名肺转移患者异常的肺静脉血流模式。
