Abstract：
We present unusual coronary-pulmonary collaterals in a 65-year-old CTEPH patient. Perfusion mapping of a dual-energy computed tomography (DECT) study revealed areas of right lung that were minimally perfused despite unilateral occlusion of the right pulmonary artery, leading to the discovery of coronary-pulmonary collaterals via invasive coronary angiography. Pulmonary thromboendarterectomy removed the clot en-bloc. Post-surgery DECT and catheterization confirmed restoration of pulmonary arterial circulation and excellent hemodynamic response. Here, suggestion of perfusion to a proximally obstructed lung with DECT helped to document the presence of rarely documented coronary-pulmonary artery collaterals.
摘要：
我们在65岁的CTEPH患者中介绍了异常的冠状动脉-肺动脉侧支。双能计算机断层扫描（DECT）研究的灌注图显示，尽管右肺动脉单侧闭塞，但右肺区域的灌注程度最低。导致通过侵入性冠状动脉造影发现冠肺络脉。肺血栓内膜切除术去除血块。术后DECT和导管插入证实肺动脉循环恢复和良好的血流动力学反应。这里,建议使用DECT对近端阻塞的肺进行灌注，有助于记录罕见的冠状动脉-肺动脉侧支的存在。
