英国学者Broberg等发现,艾森曼格综合征患者发生肺动脉栓塞时出现心功能下降和肺动脉血流速度降低。作者选择55例成人艾森曼格综合征患者行CT肺动脉成像,心血管MRI,心脏彩超检测心功能、肺动脉内径及肺动脉血流速度,同时测定血液高凝状态和血小板功能。结果显示,55例患者中,11例(20%)可检测出血栓,与无肺动脉栓塞的患者相比, British scholar Broberg et al. Found that patients with Eisenmenger’s syndrome had decreased cardiac function and decreased pulmonary blood flow velocity during pulmonary embolism. We selected 55 patients with adult Eisenmenger’s syndrome who underwent CT pulmonary angiography, cardiac MRI, cardiac function, pulmonary artery diameter and pulmonary blood flow velocity, and blood hypercoagulability and platelet function. The results showed that in 55 patients, thrombi were detected in 11 (20%), compared with patients without pulmonary embolism,
