A case of angiography-proven multiple coarctations of the pulmonary arteries is presented. The patient had a history of long-standing exertional dyspnea and intranasal cocaine use. A chest radiograph suggested oligemia in the left lung and enlargement of the right pulmonary artery, prompting ventilation and perfusion radionuclide lung imaging. The combined scintigraphic and radiographic findings were indistinguishable from those caused by pulmonary emboli. Although rare, this entity should be included in the differential diagnosis of multiple unmatched perfusion defects on pulmonary ventilation-perfusion studies.
本文报告一例经血管造影证实的多发性肺动脉缩窄病例。患者有长期劳力性呼吸困难病史且有鼻内使用可卡因史。胸部X线片提示左肺血流减少及右肺动脉增粗，促使进行通气和灌注放射性核素肺显像。闪烁显像与放射影像学联合检查结果与肺栓塞所致者难以区分。尽管此实体罕见，但在肺通气-灌注研究中出现多个不匹配灌注缺损的鉴别诊断中应考虑到它。
