In some patients acute pulmonary emboli may fail to resolve normally, resulting in chronic pulmonary embolism. This may lead to pulmonary hypertension, respiratory insufficiency, cor pulmonale, and death. The angiographic evaluation in nine patients with chronic pulmonary embolism who underwent embolectomy is presented. Particular emphasis on the predictive value of selective bronchial arteriography in four of these patients is considered. In chronic pulmonary embolism, pulmonary arteries distal to obstructed areas may remain patent and be supplied by hypertrophied bronchial arteries. Since back-bleeding of arterial blood from the bronchial circulation at surgery may predict the success of embolectomy, preoperative bronchial arteriography may be useful for predicting potential surgical success.
在一些患者中，急性肺栓塞可能无法正常消退，从而导致慢性肺栓塞。这可能会导致肺动脉高压、呼吸功能不全、肺源性心脏病和死亡。本文介绍了对9例接受栓子切除术的慢性肺栓塞患者的血管造影评估。特别强调了其中4例患者选择性支气管动脉造影的预测价值。在慢性肺栓塞中，阻塞区域远端的肺动脉可能保持通畅，并由肥大的支气管动脉供血。由于手术时支气管循环中动脉血的回流血可能预示栓子切除术的成功，术前支气管动脉造影可能有助于预测潜在的手术成功率。
