Pulmonary artery pseudoaneurysms (PAPAs) are rare and potentially fatal vascular complications that often require early detection. Most common etiologies are infection and trauma (including iatrogenic from procedures like pulmonary artery catheterization or lung biopsy). Early clinical signs include hemoptysis, dyspnea, and hemodynamic instability. Diagnostic workup should always include appropriate imaging modality, with computerized tomography (CT) and CT angiography as important diagnostic tools. Given the limited number of reported cases, treatment is not definitive and is largely guided by symptoms and patient present. In the case of massive hemoptysis, coil embolization or pulmonary vascular stenting is the preferred option. In the current case of asymptomatic PAPA, we will outline a more conservative approach to treating PAPA.
肺动脉假性动脉瘤（PAPA）是一种罕见且可能致命的血管并发症，通常需要早期检测。最常见的病因是感染和创伤（包括肺动脉导管插入术或肺活检等操作引起的医源性创伤）。早期临床症状包括咯血、呼吸困难和血流动力学不稳定。诊断检查应始终包括适当的成像方式，计算机断层扫描（CT）和CT血管造影是重要的诊断工具。鉴于报道的病例数量有限，治疗尚无定论，主要根据症状和患者情况来指导。在大量咯血的情况下，弹簧圈栓塞或肺血管支架置入是首选方案。在当前无症状PAPA的病例中，我们将概述一种更保守的PAPA治疗方法。
