At various times after clinical embolism, bronchial arteriography was performed in 23 patients with documented pulmonary embolism. In 17 patients with no radiologic infiltrates, chronic stage bronchial arteriograms demonstrated bronchial-to-pulmonary arterial collaterals with antegrade filling of distal pulmonary arteries. No collateral circulation was detected at the acute stage. In one case of massive pulmonary embolism with well-developed bronchial-to-pulmonary arterial collaterals and antegrade filling of distal pulmonary arteries, brisk back-bleeding occurred at surgery, and an excellent therapeutic result following thromboembolectomy was gained. By contrast, in six patients with radiologic infiltrates, only one patient (subacute stage) showed bronchial-to-pulmonary arterial collaterals; these were peripheral and associated with retrograde, not antegrade, filling of distal pulmonary arteries. Bronchial arteriography has provided information about the development of collateral circulation in pulmonary embolism, and might be useful when thromboembolectomy is planned.
在临床发生栓塞后的不同时间，对23例有记录的肺栓塞患者进行了支气管动脉造影。在17例无放射学浸润的患者中，慢性期支气管动脉造影显示支气管至肺动脉的侧支循环，远端肺动脉呈顺行充盈。急性期未检测到侧支循环。在1例有发达的支气管至肺动脉侧支循环且远端肺动脉顺行充盈的大面积肺栓塞病例中，手术时出现了活跃的回血，血栓切除术取得了极佳的治疗效果。相比之下，在6例有放射学浸润的患者中，只有1例（亚急性期）显示有支气管至肺动脉的侧支循环；这些侧支位于外周，与远端肺动脉的逆行而非顺行充盈有关。支气管动脉造影提供了有关肺栓塞侧支循环发展的信息，在计划进行血栓切除术时可能有用。
