Successful Long-term Management of Two Cases of Moderate Hemoptysis Due to Chronic Cavitary Pulmonary Aspergillosis with Bronchial Occlusion Using Silicone Spigots

A 65-Year-Old Man with Refractory Hemoptysis Associated with Chronic Progressive Pulmonary Aspergillosis Who Failed to Respond to Combined Endobronchial Occlusion and Bronchial Artery Embolization: A Case Report and Literature Review

BACKGROUND Hemoptysis due to airway hemorrhage is treated with hemostatic agents, bronchial artery embolization (BAE), or surgical resection. We present the case of a 65-year-old man with refractory hemoptysis associated with chronic progressive pulmonary aspergillosis (CPPA) who failed to respond to combined endobronchial occlusion (EBO) with endobronchial Watanabe spigot (EWS) and BAE. CASE REPORT A 63-year-old man was diagnosed with CPPA in the right upper lung and presented to our hospital 2 years later for hemoptysis at age 65. He developed severe hemoptysis during an outpatient visit, and was urgently admitted, intubated, and ventilated to prevent choking on blood clots. Chest computed tomography showed a large mass in the apical portion of the right lung, constituting apical pleural thickening and an encapsulated pleural effusion, and dilatation in the bronchial artery supplying the right upper lung lobe. Bronchoscopy revealed the right upper lobe B1-B3 as the bleeding source. The patient had recurrent hemoptysis that was not controlled by BAE or 6 EBO+EWS procedures, and he ultimately died of hypoxemia.In the literature review, EBO+EWS can effectively control hemoptysis in appropriate cases, without the need for BAE or surgical lung resection. It is less invasive, is associated with fewer adverse events than BAE or surgery, and can achieve temporary hemostasis for severe hemoptysis. CONCLUSIONS BAE and EBO+EWS were ineffective in controlling recurrent hemoptysis caused by CPPA in this case. However, a multidisciplinary approach such as attempting hemostasis with combined EBO+EWS and BAE may be a viable treatment option in severe cases of hemoptysis.

Massive hemoptysis in a post-operative patient with recurrent lung cancer successfully treated by the combination therapy of Endobronchial Watanabe Spigot and bronchial artery embolization

A 76-year-old woman who was treated with lorlatinib for postoperative recurrent anaplastic lymphoma kinase-positive lung adenocarcinoma visited our hospital with massive hemoptysis. Chest computed tomography showed massive bleeding from the right upper lobe; however, the cause of bleeding was unclear. After bronchial artery embolization (BAE), bronchial occlusion was performed using an Endobronchial Watanabe Spigot (EWS) that was easily placed because BAE had reduced the bleeding volume. Treatment with BAE alone was inadequate; however, additional therapy with EWS after BAE successfully controlled the massive hemoptysis, especially in this patient who underwent lobectomy to prevent respiratory dysfunction.

A Collaborative Tale of Diagnosing and Treating Chronic Pulmonary Aspergillosis, from the Perspectives of Clinical Microbiologists, Surgical Pathologists, and Infectious Disease Clinicians

Chronic pulmonary aspergillosis (CPA) refers to a spectrum of Aspergillus-mediated disease that is associated with high morbidity and mortality, with its true prevalence vastly underestimated. The diagnosis of CPA includes characteristic radiographical findings in conjunction with persistent and systemic symptoms present for at least three months, and evidence of Aspergillus infection. Traditionally, Aspergillus infection has been confirmed through histopathology and microbiological studies, including fungal culture and serology, but these methodologies have limitations that are discussed in this review. The treatment of CPA requires an individualized approach and consideration of both medical and surgical options. Most Aspergillus species are considered susceptible to mold-active triazoles, echinocandins, and amphotericin B; however, antifungal resistance is emerging and well documented, demonstrating the need for novel therapies and antifungal susceptibility testing that correlates with clinical response. Here, we describe the clinical presentation, diagnosis, and treatment of CPA, with an emphasis on the strengths and pitfalls of diagnostic and treatment approaches, as well as future directions, including whole genome sequencing and metagenomic sequencing. The advancement of molecular technology enables rapid and precise species level identification, and the determination of molecular mechanisms of resistance, bridging the clinical infectious disease, anatomical pathology, microbiology, and molecular biology disciplines.
