目的:比较支气管肺的络脉的可视化和支气管肺的抵押品慢性血栓栓塞肺动脉高压患者的血液循环第二原发性肺动脉高压。设置:在学术医院转诊中心的心脏病。病人:九个慢性血栓栓塞肺动脉高压患者和17原发性肺动脉高压。干预措施:支气管肺的担保物被选择性支气管动脉造影或胸造影术形象化。支气管肺的抵押品血液流动被注入吲哚菁绿估计下面的升主动脉和抽样的二尖瓣左心室。结果:肺动脉高压程度相当的两组。大支气管肺的络脉呈现在所有的血栓栓塞肺动脉高压患者支气管动脉造影术或造影术或两者兼而有之。没有一个原发性肺动脉高压组研究造影术有支气管肺的担保物(P < < 0.001)。所有的慢性血栓栓塞肺动脉高压患者有明显的支气管肺的抵押品血液流动,这是(平均(SD)) 29.8(18.6) %的全身血液流动。没有可记录的抵押品血液流动在11 15原发性肺动脉高压患者。 In the remaining four patients the mean value was 1.1 (1.8)% of the systemic blood flow (P < < 0.001). CONCLUSIONS: Visualisation of bronchopulmonary collaterals by thoracic aortography or by bronchial arteriography, or the demonstration of an increased bronchopulmonary collateral flow, helps to distinguish patients with chronic thromboembolic pulmonary hypertension from those with primary pulmonary hypertension.
