Massive hemoptysis is a potentially lethal condition that deserves to be investigated thoroughly and brought under control promptly. The mortality rate depends mainly on the underlying etiology and the magnitude of bleeding. Although the diagnosis of hemoptysis may be established by chest radiograph, many pathologies may be missed. Because bronchoscopy and computed tomography are complementary, they may indicate pathologies not detectable by chest radiograph. Finding the etiology and site of the hemoptysis is imperative.
Urgent bronchoscopy should be performed in unstable patients because it exacts a paramount role in the diagnostic search and therapy. It can be used to facilitate the introduction of balloon-tip catheters into the bleeding bronchus for tamponade of the hemorrhagic artery, protecting de facto the contralateral lung or nonbleeding bronchi from blood aspiration. Endobronchial tamponade should only be used as a temporary measure until a more specific treatment is instituted. In stable patients, computed tomography should be ordered before any bronchoscopic exploration.
Surgery was once regarded as the treatment of choice in operable patients with massive hemoptysis. Bronchial artery embolization (BAE) is an excellent nonsurgical alternative; it is proven to be very effective and lacks the mortality and morbidity encountered in surgical interventions. Nevertheless, surgery is recommended in patients with massive hemoptysis caused by thoracic vascular injury, arteriovenous malformation, leaking thoracic aneurysm with bronchial communication, hydatid cyst, and other conditions in which BAE would be inadequate. MEDICAL MANAGEMENT: Conservative medical therapy may suffice in certain conditions, like bronchiectasis, coagulopathies, Goodpasture's syndrome, and acute bronchopulmonary infections. Preparation for other interventions (endobronchial tamponade, BAE, or surgery in eligible candidates) should be undertaken if the bleeding fails to respond to conservative measures. Supportive therapy should be applied vigorously to all patients with massive hemoptysis.
大量咯血是一种潜在的致命病症,值得进行全面调查并迅速加以控制。死亡率主要取决于潜在病因和出血量。虽然咯血的诊断可通过胸部X光片确定,但许多病变可能会被漏诊。由于支气管镜检查和计算机断层扫描具有互补性,它们可能会显示出胸部X光片无法检测到的病变。找出咯血的病因和部位至关重要。
对于病情不稳定的患者,应紧急进行支气管镜检查,因为它在诊断和治疗中起着至关重要的作用。它可用于将球囊导管插入出血支气管以压迫出血动脉,实际上可保护对侧肺或未出血的支气管不被血液吸入。支气管内压迫仅应作为临时措施,直至采取更具体的治疗方法。对于病情稳定的患者,在进行任何支气管镜检查之前应先进行计算机断层扫描。
手术曾被视为可手术治疗的大量咯血患者的首选治疗方法。支气管动脉栓塞术(BAE)是一种极好的非手术替代方法;事实证明它非常有效,且没有手术干预中出现的死亡率和发病率。然而,对于由胸血管损伤、动静脉畸形、伴有支气管相通的漏出性胸主动脉瘤、包虫囊肿以及其他BAE治疗不足的情况引起的大量咯血患者,建议进行手术。
在某些情况下,如支气管扩张、凝血障碍、古德帕斯丘综合征和急性支气管肺部感染,保守药物治疗可能就足够了。如果出血对保守措施无反应,应准备进行其他干预(支气管内压迫、BAE或对符合条件的患者进行手术)。应积极对所有大量咯血患者进行支持治疗。
