RESUMEN
BACKGROUND: Massive hemoptysis is characterized by its life-threatening nature, potentially leading to airway obstruction and asphyxia. The objective of this study was to evaluate the clinical effectiveness of combining endobronchial tamponade with bronchial artery embolization (BAE) in the treatment of massive hemoptysis. METHODS: Between March 2018 and March 2022, a total of 67 patients with massive hemoptysis who underwent BAE were divided into two groups: the combination group (n = 26) and the BAE group (n = 41). Technical and clinical success rates were assessed, and adverse events were monitored following the treatment. Blood gas analysis and coagulation function indicators were collected before and after the treatment, and recurrence and survival rates were recorded during the follow-up period. RESULTS: All patients achieved technical success. There were no significant differences in the clinical success rate, recurrence rates at 3 and 6 months, and mortality rates at 3 months, 6 months, and 1 year between the combination group and the BAE group. However, the hemoptysis recurrence rate at 1 year was significantly lower in the combination group compared to the BAE group (15.4% vs. 39.0%, P = 0.039). No serious adverse events were reported in either group. After treatment, the combination group showed higher levels of arterial partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2), fibrinogen (FIB), and D-dimer (D-D) compared to the BAE group (P < 0.05). Multivariate regression analysis demonstrated a significant correlation between combined therapy and hemoptysis-free survival. CONCLUSION: Combination therapy, compared to embolization alone, exhibits superior efficacy in improving respiratory function, correcting hypoxia, stopping bleeding, and preventing recurrence. It is considered an effective and safe treatment for massive hemoptysis.

BACKGROUND: Non-small cell lung cancer (NSCLC) has a poor prognosis. Transvascular intervention is an important approach for treating NSCLC. Drug-eluting bead bronchial artery chemoembolisation (DEB-BACE) is a technique of using DEBs loaded with chemotherapeutic drugs for BACE. This study aims to conduct a meta-analysis to comprehensively assess the effectiveness and safety of DEB-BACE in treating NSCLC and investigate a novel therapeutic strategy for NSCLC. METHODS AND ANALYSIS: Wanfang, China National Knowledge Infrastructure, Medline (via PubMed), Cochrane Library, Scopus and Embase databases will be searched in November 2024. A meta-analysis will be conducted to assess the effectiveness and safety of DEB-BACE in the treatment of NSCLC. The following keywords will be applied: "Carcinoma, Non-Small-Cell Lung", "Non-Small Cell Lung Cancer", "Drug-Eluting Bead Bronchial Arterial Chemoembolization" and "drug-eluting beads". Reports in Chinese or English comparing the efficacy of DEB-BACE with other NSCLC treatment options will be included. Case reports, single-arm studies, conference papers, abstracts without full text and reports published in languages other than English and Chinese will not be considered. The Cochrane Handbook for Systematic Reviews of Interventions will be used to independently assess the risk of bias for each included study. In case of significant heterogeneity between studies, possible sources of heterogeneity will be explored through subgroup and sensitivity analysis. For the statistical analysis of the data, RevMan V.5.3 will be used. ETHICS AND DISSEMINATION: This meta-analysis will seek publication in a peer-reviewed journal on completion. Ethical approval is not required for this study as it is a database-based study. PROSPERO REGISTRATION NUMBER: CRD42023411392.

AIM: This study assesses the safety and efficacy of particle embolization during bronchial artery embolization (BAE) in patients with shunts between bronchial and non-bronchial systemic arteries and the pulmonary artery. METHODS: In this retrospective, single-center study, we analyzed 312 BAE procedures performed from June 2020 to April 2023. The patient cohort had shunts between bronchial and non-bronchial systemic arteries and the pulmonary artery. We meticulously collected and examined comprehensive data, including clinical characteristics, computed tomography (CT) imaging, and embolization procedural details. RESULTS: Vascular shunts were identified in 49 patients. The etiologies of hemoptysis included post-TB sequelae (42.8%), bronchiectasis (26.5%), active TB (12.2%), aspergilloma (8.1%), bacterial pneumonia (4.1%), lung cancer (4.1%), and non-tuberculous mycobacterial infection (2%). The technical success rate of the procedures was 98%, with 149 out of 152 identified vessels successfully embolized. All patients experienced cessation or significant reduction of hemoptysis within 24 hours following the procedure. The clinical success rates were 97.9% at one month, 93.9% at six months, and 89.8% at one year. No shunt-related complications were detected. CONCLUSION: BAE with particle embolization is a safe and effective treatment for hemoptysis, particularly in cases with complex shunts between bronchial and non-bronchial systemic arteries and the pulmonary artery.

BACKGROUND: Bronchiectasis has high rates of hemoptysis and recurrent hemoptysis, which is inconsistent among various etiologies. Idiopathic bronchiectasis and post-tuberculous bronchiectasis are two important etiologies in China, but the differences in clinical features and risk factors of recurrent hemoptysis have not been elucidated. METHODS: Patients hospitalized for idiopathic bronchiectasis or post-tuberculosis bronchiectasis were included. Patients were followed up for at least 24 months post-BAE. Demographic characteristics and clinical data were collected and analyzed between idiopathic bronchiectasis and post-tuberculosis bronchiectasis. Based on the outcomes of recurrent severe hemoptysis in patients with post-tuberculosis bronchiectasis, Cox regression models were used to identify risk factors for recurrence. RESULTS: Among 417 patients including 352 idiopathic bronchiectasis and 65 post-tuberculous bronchiectasis, 209 (50.1%) were females. Compared with the idiopathic group, the proportion of patients with female (54.5% vs. 26.2%, p < 0.001), with sputum (79.5% vs. 36.9%, p < 0.001), isolation of Pseudomonas aeruginosa (28.7% vs. 7.7%, p < 0.001), and the number of bronchiectatic lobes≥ 3(98.3% vs 50.8%, p < 0.001) were lower, and the proportion of destroyed lung (4.5% vs. 26.6%, p < 0.001) and recurrence of severe hemoptysis (22.4% vs. 41.5%, p = 0.001) were higher in the post-tuberculous group. Among patients with post-tuberculosis bronchiectasis, destroyed lung [HR: 3.2(1.1,9.1), p = 0.026] and abnormal esophageal proper artery [HR: 2.8(1.1,7.0), p = 0.032] were two independent risk factors for the recurrence of hemoptysis. CONCLUSIONS: The recurrence rate of severe hemoptysis in patients with post-tuberculous bronchiectasis receiving BAE is high, and the proper esophageal artery should be actively evaluated and standardized treatment should be given.

BACKGROUND: Airway stenting is an established procedure for treating oncological emergencies in patients with airway disorders. In patients with airway hemorrhage, respiratory conditions may worsen during stenting. Bronchial artery embolization (BAE) is useful to prevent bleeding from the bronchus. We aimed to evaluate the efficacy and safety of airway stenting after BAE in patients with malignant airway disorders. METHODS: The medical records of all patients who underwent airway stenting following BAE at the National Hospital Organization Okayama Medical Center between 2016 and 2023 were retrospectively reviewed. RESULTS: Thirteen procedures (11 silicone Y stents, one hybrid stent, and one self-expandable metallic stent) were performed. The median duration from BAE to airway stenting was one day (range: 1-5 days). Nine patients experienced tumor shrinkage, and none experienced severe bleeding after BAE during the stent procedure. No other major complications were associated with the stent placement. The median survival time after stenting was 169 days (range; 24-1086). No serious complications caused by BAE, such as spinal cord infarction, were observed. CONCLUSIONS: Airway stent placement was safely performed after BAE without severe bleeding or acute respiratory failure. BAE, followed by airway stenting, is useful.

Pulmonary actinomycosis is a rare infectious disease that can be difficult to diagnose due to nonspecific imaging abnormalities and to a need for repeated lung sampling by CT-guided biopsy or bronchoscopy. It may present with hemoptysis, which can occur with or without antibiotic therapy and bronchial artery embolization may be required. We report here a case of pulmonary actinomycosis with imaging by thoracic CT, digital subtraction angiography, and pathological specimens.

The pathophysiology of pulmonary hypertension (PH) is not fully understood. Here, we tested the hypothesis that hypoxic perfusion of the vasa vasorum of the pulmonary arterial (PA) wall causes PH. Young adult pig lungs were explanted and placed into a modified ex vivo lung perfusion unit (organ care system, OCS) allowing the separate adjustment of parameters for mechanical ventilation, as well as PA perfusion and bronchial arterial (BA) perfusion. The PA vasa vasorum are branches of the BA. The lungs were used either as the control group (n = 3) or the intervention group (n = 8). The protocol for the intervention group was as follows: normoxic ventilation and perfusion (steady state), hypoxic BA perfusion, steady state, and hypoxic BA perfusion. During hypoxic BA perfusion, ventilation and PA perfusion maintained normal. Control lungs were kept under steady-state conditions for 105 min. During the experiments, PA pressure (PAP) and blood gas analysis were frequently monitored. Hypoxic perfusion of the BA resulted in an increase in systolic and mean PAP, a reaction that was reversible upon normoxic BA perfusion. The PAP increase was reproducible during the second hypoxic BA perfusion. Under control conditions, the PAP stayed constant until about 80 min of the experiment. In conclusion, the results of the current study prove that hypoxic perfusion of the vasa vasorum of the PA directly increases PAP in an ex situ lung perfusion setup, suggesting that PA vasa vasorum function and wall ischemia may contribute to the development of PH.NEW & NOTEWORTHY Hypoxic perfusion of the vasa vasorum of the pulmonary artery directly increased pulmonary arterial pressure in an ex vivo lung perfusion setup. This suggests that the function of pulmonary arterial vasa vasorum and wall ischemia may contribute to the development of pulmonary hypertension.

BACKGROUND: Bronchial arterial embolization (BAE) has been accepted as an effective treatment for bronchiectasis-related hemoptysis. However, rare clinical trials compare different sizes of specific embolic agents. This study aims to evaluate whether different Embosphere microsphere sizes change the outcome of BAE. METHODS: A retrospective review was conducted on consecutive patients with bronchiectatic hemoptysis who were scheduled to undergo BAE treatment during a period from January 2018 to December 2022. The patients received BAE using microspheres of different sizes: group A patients were treated with 500-750 µm microspheres, and group B patients were treated with 700-900 µm microspheres. The cost of embolic microspheres (Chinese Yuan, CNY), duration of hospitalization, complications, and hemoptysis-free survival were compared between patients in group A and those in group B. A Cox proportional hazards regression model was used to identify predictors of recurrent hemoptysis. RESULTS: Median follow-up was 30.2 months (range, 20.3-56.5 months). The final analysis included a total of 112 patients (49-77 years of age; 45 men). The patients were divided into two groups: group A (N = 68), which received 500-750 µm Embosphere microspheres, and group B (N = 44), which received 700-900 µm Embosphere microspheres. Except for the cost of embolic microspheres(group A,5314.8 + 1301.5 CNY; group B, 3644.5 + 1192.3 CNY; p = 0.042), there were no statistically significant differences in duration of hospitalization (group A,7.2 + 1.4 days; group B, 8 + 2.4days; p = 0.550), hemoptysis-free survival (group A, 1-year, 2-year, 3-year, 85.9%, 75.8%, 62.9%; group B, 1-year, 2-year, 3-year, 88.4%, 81.2%,59.4%;P = 0.060), and complications(group A,26.5%; group B, 38.6%; p = 0.175) between the two groups. No major complications were observed. The multivariate analysis results revealed that the presence of cystic bronchiectasis (OR 1.61, 95% CI 1.12-2.83; P = 0.001) and systemic arterial-pulmonary shunts (SPSs) (OR 1.52, 95% CI 1.10-2.72; P = 0.028) were independent risk factors for recurrent bleeding. CONCLUSIONS: For the treatment of BAE in patients with bronchiectasis-related hemoptysis, 500-750 µm diameter Embosphere microspheres have a similar efficacy and safety profile compared to 700-900 µm diameter Embosphere microspheres, especially for those without SPSs or cystic bronchiectasis. Furthermore, the utilization of large-sized (700-900 µm) Embosphere microspheres is associated with the reduced cost of an embolic agent.

PURPOSE: This retrospective study aimed to investigate the effectiveness and safety of bronchial arterial chemoembolization with drug-eluting beads (DEB-BACE) plus chemotherapy versus chemotherapy alone in patients with stage III and IV lung squamous cell carcinoma (LSCC) who are not appropriate candidates for radiochemotherapy. MATERIALS AND METHODS: In this retrospective analysis, we screened all adult patients undergoing either DEB-BACE plus chemotherapy or chemotherapy alone for stage III or IV LCSS at authors' center from January 2018 to August 2021. Each 21-day chemotherapy cycle consisted of intravenous injection of gemcitabine (1.0 g/m2) on days 1 and 8 and cisplatin 75 (mg/m2) on day 1. The planned cycles were 4. DEB-BACE consisted of microcatheter infusion of CalliSpheres beads carrying cisplatin (75 mg/m2) and gemcitabine (1.0 g/m2), at 3 weeks prior to chemotherapy. The primary outcome was overall survival (OS). The secondary outcomes included progression-free survival (PFS), pulmonary response, and adverse events (AEs). RESULTS: The final analysis included 95 patients in the chemotherapy group and 41 patients in the combination treatment group. The median OS was 14 months (95 % CI 11.0-17.0) in the chemotherapy group and 19 months (95 % CI 18.0-24.0) in the combination group (P = 0.015). In multivariate Cox regression analysis, DEB-BACE plus chemotherapy was associated with lower risk of death versus chemotherapy only (HR 0.16, 95 % CI 0.05-0.52; log rank test P = 0.003). The median PFS was 6 months (95 % CI 4.0-7.0) in the chemotherapy group and 8 months (95 % CI 6.0-8.0) in the combination group (P = 0.015). The pulmonary objective response rate (ORR) and disease control rate (DCR) were 48.4 % and 62.1 % in chemotherapy group versus 82.9 % and 90.2 % in combination group (P < 0.001 and = 0.001, respectively). AEs occurred in 133 patients (97.8 %). The rate of bone marrow suppression was 48.4 % (46/95) in the chemotherapy group versus 7.3 % (3/41) in the combination group (P < 0.001). CONCLUSION: Compared with chemotherapy alone, DEB-BACE plus chemotherapy was associated with longer survival outcomes and lower rate of bone marrow suppression.

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.

OBJECTIVE: Comparing the efficacy and safety of particulate [microspheres/polyvinyl alcohol (PVA)] and non-particulate [n-butyl-2-cyanoacrylate (NBCA)] agents used as the embolic agents for bronchial artery embolization (BAE) intervention in patients experiencing massive hemoptysis. PATIENTS AND METHODS: A total of 58 individuals (47 male, 11 female, standard deviation = 53.9 ± 14.8, age range = 18-84) were recruited for a retrospective study in a single unit. Thirty (51.7%) of the patients underwent BAE intervention with NBCA, and 28 (48.3%) underwent the same procedure with a particulate embolizing agent (microspheres/PVA). The demographic distribution of the patients, the etiological factors, the technical and clinical success rates, and complications were documented, with the two groups subsequently compared. RESULTS: The technical and clinical success rates following the procedure were 100% for both groups. The average follow-up duration was 34 months in the NBCA group and 33.5 months in the particulate embolizing agent group. In comparison, the rate of recurrent hemoptysis was 3.3% in the former and 17.9% in the latter, with the presence of recurrent hemoptysis not statistically different between the two groups (p = 0.097). Major complications and procedural death did not occur in either of the samples. CONCLUSIONS: The use of NBCA in BAE presents a safe and effective method. The combination of NBCA and particulate embolizing agents (PVA/microspheres) achieved equal technical and clinical success and significantly increased the hemoptysis-free survival rates in terms of life-threatening hemoptysis. MAIN POINTS: (1) In managing massive hemoptysis, using NBCA is a safe and effective method similar to using particulate embolizing agents. (2) Although not statistically significant, recurrent hemoptysis is observed less frequently in the NBCA group. (3) Technique and clinical success were relatively high and similar in the groups where NBCA and particulate embolizing agents were used.

Bronchial artery embolisation (BAE) is a treatment used to manage haemoptysis. We performed a 7-year review of BAE procedures for haemoptysis at our CF centre aiming to evaluate the incidence and outcomes of patients with neurovascular complications post-BAE. Our review suggests that whilst BAE is an effective method for controlling life-threatening haemoptysis, patients are at risk of developing neurovascular complications with long term residual symptoms, and therefore careful consideration should be given in offering BAE, especially to otherwise well patients with chronic small volume haemoptysis and managing teams should have a low threshold to image symptomatic patients.

BACKGROUND: Postoperative pneumonia is a common and major cause of mortality after radical esophagectomy. Intraoperative preservation of the bronchial arteries is often aimed at avoiding tracheobronchial ischemia; however, it is unknown whether this contributes to a reduction in postoperative pneumonia. PATIENTS AND METHODS: We enrolled 348 consecutive patients who underwent radical esophagectomy for esophageal cancer at Toranomon Hospital from January 2011 to July 2018. We classified patients into a bronchial artery-resected (BA-R) group (n = 93) and a bronchial artery-preserved (BA-P) group (n = 255) and compared the incidence of postoperative pneumonia between the two groups. A propensity score-matching analysis for bronchial artery preservation versus resection was performed. RESULTS: Overall, 182 patients were matched. Univariate analysis of the propensity score-matched groups showed that Brinkman index ≥ 400, vital capacity (%VC) < 80%, and bronchial artery resection were associated with the development of postoperative pneumonia. Multivariate analysis revealed three significant factors associated with postoperative pneumonia: Brinkman index ≥ 400 [p = 0.006, odds ratio (HR) 3.302, 95% confidence interval (95% CI) 1.399-7.790], %VC < 80% (p = 0.034, HR 6.365, 95% CI 1.151-35.205), and bronchial artery resection (p = 0.034, HR 2.131, 95% CI 1.060-4.282). The incidence of postoperative complications (CD grade III) was higher in the BA-R group (BA-R 42.8% versus BA-P 27.5%, p = 0.030). There was no significant difference in overall survival between the two groups at 5 years (BA-R 63.1% versus BA-P 72.1%, p = 0.130). CONCLUSION: Preserving the bronchial artery is associated with a decreased incidence of postoperative pneumonia.

AIM: To report the authors' experience of bronchial artery embolisation (BAE) in a series of patients to control haemoptysis associated with infected pulmonary artery pseudoaneurysms (PAPs). MATERIALS AND METHODS: All patients who underwent BAE based on computed tomography angiography (CTA) findings indicative of haemoptysis between February 2019 and September 2022 at Xiangyang Central Hospital were identified. Charts of patients with haemoptysis and infectious PAPs were reviewed retrospectively. Data were collected data on age, sex, underlying pathology, source pulmonary artery of the PAP, association with cavitary lesions or consolidation, systemic angiography findings, technical and clinical success, and follow-up. RESULTS: Seventeen PAPs were treated in 16 patients, with a mean age of 60.3 years (range: 37-82 years). The most common underlying cause was tuberculosis (15/16, 93.8%). Imaging by CTA did not identify the source pulmonary artery for 15 (88.2%) PAPs; all were associated with cavitary lesions or consolidation. All PAPs were visualised on systemic angiography. The technical and clinical success rates were both 87.5%. Two patients who experienced a recurrence of haemoptysis during follow-up underwent repeat CTA, which confirmed the elimination of the previous PAP. CONCLUSION: BAE may be a valuable technique to control haemoptysis associated with infectious PAPs that are visualised on systemic angiography. A possible contributing factor is PAPs arising from very small pulmonary arteries.
