{"title":"Transforming pulmonary care with applications of endobronchial valves beyond emphysema: a narrative review.","authors":"Munir Adamu Bala, Ra'fat Tawalbeh, Vasileios Kouritas","doi":"10.21037/atm-25-138","DOIUrl":"10.21037/atm-25-138","url":null,"abstract":"<p><strong>Background and objective: </strong>Endobronchial one‑way valves (EBVs) were originally developed for lung volume reduction in severe emphysema. Because EBVs allow unidirectional airflow, they have been used off‑label to manage persistent air leaks (PALs)/bronchopleural fistulas (BPFs), haemoptysis, cavitary tuberculosis (TB), and other complex pulmonary conditions. This review summarises the evidence of endobronchial valve applications beyond emphysema.</p><p><strong>Methods: </strong>We conducted a narrative review of English‑language literature from January 1, 2000 to August 1, 2025, searching PubMed, Embase, Scopus, and Google Scholar for clinical trials, observational studies, case series, and case reports describing EBV use beyond emphysema. The selection of articles was based on relevance to the topic, with emphasis on clinical outcomes. No formal quantitative synthesis was performed given the narrative scope.</p><p><strong>Key content and findings: </strong>Across case series, EBV placement achieves cessation or substantial reduction of air leaks in roughly half to 80% of patients with postoperative or spontaneous BPFs, often allowing chest tube removal within days and avoiding reoperation. Reported complications are uncommon and include valve migration, expectoration, transient hypoxaemia, and localized infection. Case reports indicate EBVs can serve as emergency bronchoscopic plugs to control massive haemoptysis when conventional therapy fails. Emerging evidence in multidrug‑resistant TB shows that collapse therapy using EBVs alongside appropriate chemotherapy accelerates sputum culture conversion and cavity closure; in a randomized trial, EBV treatment markedly improved culture conversion and long‑term cure rates compared with chemotherapy alone. EBVs have also been used in critical care settings to isolate injured lungs and facilitate weaning from mechanical ventilation or extracorporeal membrane oxygenation (ECMO).</p><p><strong>Conclusions: </strong>EBVs have evolved into a versatile tool in pulmonary medicine, extending well beyond emphysema treatment. The literature to date indicates that EBVs can effectively seal PALs, control focal pulmonary haemorrhage, and induce therapeutic lung collapse in cavitary disease-all with a minimally invasive approach. EBVs hold significant promise for improving patient care in challenging scenarios, and further research is warranted.</p>","PeriodicalId":8216,"journal":{"name":"Annals of translational medicine","volume":"13 6","pages":"77"},"PeriodicalIF":0.0,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12771056/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145916595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While both induced and spontaneous IVDD animal models have provided valuable insights, they also present inherent limitations that restrict their translational applicability. Increasing evidence supports the use of sheep as a highly relevant large animal model, as spontaneous spine disorders in this species closely mirror many features of human IVDD. Sheep exhibit remarkable similarities to humans in terms of disc cellular composition, anatomical configuration, physiological loading, histological architecture, and molecular signaling pathways. These features make the ovine model uniquely positioned to bridge the gap between basic science and clinical translation, fulfilling both scientific and regulatory requirements. In this review, we highlight the shared features of IVDD between sheep and humans and examine both spontaneous and induced ovine models currently used to study disc degeneration. Furthermore, we discuss how the integration of advanced technologies, such as surgical navigation systems can refine the reproducibility and precision of these models. These innovations not only enhance experimental rigor but also strengthen the translational value of the ovine model, advancing our understanding of IVDD pathophysiology, diagnosis, prevention, and treatment. Continued refinement of ovine models will play a critical role in the development of effective therapeutic strategies for managing IVDD in humans.</p>","PeriodicalId":8216,"journal":{"name":"Annals of translational medicine","volume":"13 6","pages":"79"},"PeriodicalIF":0.0,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12771051/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145916585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
