| ［摘要］ 肺部高压的支气管动脉与肺静脉构成体循环，低压的肺动脉与肺静脉构成肺循环，支气管动脉、肺动脉和肺静脉三种血管构成肺部两套循环系统。体循环的高压动脉形成动静脉畸形包括支气管动脉-肺静脉畸形和支气管动脉-肺动脉畸形，动静脉畸形的供养动脉、畸形血管团和引流静脉极易形成动脉瘤，动脉瘤破裂引发大咯血。而肺动脉瘤少见，易被漏诊，肺动脉瘤的血供可单独来源于肺循环或体循环，也可同时累及肺循环和体循环，肺动脉瘤破裂大咯血单纯体循环动脉栓塞难以控制。因此，要重视大咯血患者肺动脉瘤的诊断与介入治疗。 |

| Abstract: |
| ［Abstract］ The lungs have a dual blood supplies constituted by bronchial artery, pulmonary artery and pulmonary vein. The high-pressure bronchial artery and pulmonary vein consists the systemic circulation and the low-pressure pulmonary artery and pulmonary vein consists the pulmonary arterial circulation. Arteriovenous malformations of systemic high-pressure arteries include bronchial artery-pulmonary vein malformations and bronchial-pulmonary artery malformations. The feeding arteries, malformed vascular masses and drainage veins of arteriovenous malformations are easy to form aneurysms. Massive hemoptysis can be caused by ruptured pulmonary artery aneurysm. Pulmonary artery aneurysm is rare and easy to be missed in diagnosis. The blood supply of pulmonary artery aneurysm can origin from pulmonary circulation or systemic circulation alone, and can also involve pulmonary circulation and systemic circulation at the same time. It is difficult to control the ruptured pulmonary artery aneurysm with massive hemoptysis by systemic arterial embolization alone. Therefore, attention should be paid to the diagnosis and interventional treatment of pulmonary artery aneurysms in patients with massive hemoptysis. |
