AI Article Synopsis
- Chronic pulmonary arterial obstructions typically arise from chronic thromboembolism, but can also be linked to rare conditions like vasculitis or intimal sarcoma.
- A unique case of a 42-year-old woman with a solitary pulmonary artery obstruction led to a lobectomy, as the possibility of intimal sarcoma could not be ruled out.
- The analysis of the resected samples showed large vessel vasculitis, suggesting it should be included as a potential cause for single pulmonary artery obstructions.
Article Abstract
Chronic pulmonary arterial obstructions are caused mostly by chronic pulmonary artery thromboembolism and rarely by vasculitis or intimal sarcoma of the pulmonary artery. We herein report an unusual case of a 42-year-old woman with a solitary obstruction of the pulmonary artery in the right lower lobe of her lung. Because we could not exclude the possibility of intimal sarcoma, middle and lower lobectomy was performed. The resected specimens revealed large vessel vasculitis (LVV) and an isolated lesion in the right lower lobe pulmonary artery. LVV should therefore be considered in the differential diagnosis for single pulmonary arterial stenosis or obstruction.

Targeted FTO knockout in endothelial cells Boosts adhesion and lowers inflammatory infiltration to alleviate pulmonary arterial hypertension.
Biochem Biophys Res Commun
January 2025
Department of Ultrasonography, Fuwai Yunnan Hospital, Chinese Academy of Medical, Sciences/Affiliated Cardiovascular Hospital of Kunming Medical University, Kunming, 650102, China. Electronic address:
Pulmonary arterial hypertension (PAH) is a syndrome characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, ultimately leading to right heart failure and even death. Increasing evidence implicates the fat mass and obesity-associated protein (FTO) in various metabolic and inflammatory pathways; however, its role in pulmonary endothelial function and PAH remains largely unexplored. In this study, we examined the effects of endothelial cell-specific FTO knockout on PAH development.

Background: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection, hospitalisation and death in adults.
Methods: Based on evidence regarding the impact of RSV on adult populations at risk for severe infection and the efficacy and safety of RSV vaccines, the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine endorses this position paper with recommendations to prevent RSV-associated disease and its complications in adults through vaccination.
Conclusion: The RSV vaccine is recommended for people aged ≥50 years with risk factors (chronic obstructive pulmonary disease, asthma, heart failure, coronary artery disease, diabetes, chronic kidney disease, chronic liver disease, immunocompromise, frailty, dementia, and residence in a nursing home) and all persons aged ≥60 years.
Background: RING finger protein 213 () p.R4810K is an established risk factor for moyamoya disease and intracranial artery stenosis in East Asian people. Recent evidence suggests its potential association with extracranial cardiovascular diseases, including pulmonary hypertension.

Xuanwu Hospital, Capital Medical University, Beijing, China.
Purpose: To study the effects of breathing exercises on preventing pulmonary complications in patients undergoing coronary artery bypass graft surgery.
Methods: Observing whether preoperative breathing exercises can reduce the incidence of postoperative pulmonary complications in patients undergoing coronary artery bypass graft surgery; observing whether these exercises can improve postoperative arterial oxygen pressure, oxygen saturation, and the distance walked in a six-minute walk test after surgery; as well as reduce hospital stay duration, lower treatment costs, and improve the quality of life as measured by the Short Form-36 Health Survey (SF-36).
Design: The study population includes patients undergoing coronary artery bypass graft surgery under general anesthesia; the research center is Capital Medical University Xuanwu Hospital; the sample size is 120.

Infective endocarditis used to frequently cause mortality in subjects having PDA before the advent of antibiotics and surgical ligation. It has been documented that clinically silent PDAs may cause infective complications of heart valves. We present case of an 18-years-old male who presented with palpitations and fever to our emergency department.
