Ventilation-perfusion pulmonary scintigraphy with analysis ofventilation-perfusion ratio, apex-base ventilation and perfusion gradient, pulmonary perfusion, and the condition of alveolar permeability at the 10th and 30th min after inhalation of radiopharmaceutical was carried out in 16 patients with clinical and scintigraphic signs of thromboembolism of distal pulmonary artery branches and 10 controls. Thromboembolism of distal pulmonary artery branches was manifested by an increase in apex-base ventilation and perfusion gradient in both involved and intact lungs vs. the same parameters in healthy people. Patients with bilateral thromboembolism of distal pulmonary artery branches were characterized by an increase in ventilation-perfusion ratio and retardation of alveolar permeability.
对16例有远端肺动脉分支血栓栓塞临床及闪烁显像征象的患者和10名对照者进行了通气-灌注肺闪烁显像，分析了吸入放射性药物后第10分钟和第30分钟的通气-灌注比、尖-底通气和灌注梯度、肺灌注以及肺泡通透性状况。与健康人相同参数相比，远端肺动脉分支血栓栓塞表现为患侧肺和健侧肺的尖-底通气和灌注梯度均增加。远端肺动脉分支双侧血栓栓塞的患者表现为通气-灌注比增加和肺泡通透性延迟。
