| Abstract | [Summary] Occlusive thromboaortopathy (Takayasu's disease) causes occlusive disorder not only in the aorta and its major branches, but also in the pulmonary vascular system. In detecting the latter disorder, the lung perfusion scintigram is useful, in which like pulmonary embolism, focal perfusion defect without ventilation impairment is thought to be a characteristic finding. However, perfusion defect with ventilation impairment has been noted in our present series of investigation and this contradictive result was discussed. All of 20 cases with a established diagnosis of occlusive thromboaortopathy, showed the focal perfusion defect with the concomitant region of decreased ventilation, and in 16 cases of them, any specific cause responsible for this ventilation impairment was not evident. Quantitative assessment of radioxenon and bronchography indicated that ventilation impairment of this disease was not thought to be airway obstruction, but to be decreased compliance of the affected region, which was accompanied with decreased volume of the peripheral affected region. The reason for decreased compliance in the case with the primary pulmonary vascular disease was discussed, and the decreased production of surfactant was thought to be incriminated. |
