Pulmonary artery sling

open access: yesThe Journal of Thoracic and Cardiovascular Surgery, 1975
Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availability of a corrective operation, the mortality rate remains very high (50 per cent of surgically treated children) due to the high incidence of associated obstructive anormaliies of the tracheobronchial tree.

Irisin Attenuates Pulmonary Vascular Remodeling in Pulmonary Arterial Hypertension via Ubiquitin‐Mediated Regulation of ENO1

open access: yesAdvanced Science, EarlyView.
Irisin is a crucial plasma biomarker and promising therapeutic target that reflects disease severity, pulmonary vascular remodeling status and clinical outcome in patients with pulmonary arterial hypertension (PAH). As a novel protective factor, irisin is downregulated in PAH. By ubiquitination, irisin promotes Enolase 1 degradation and suppresses cell

4D-flow MRI assessment of blood flow before and after endovascular intervention in a patient with pulmonary hypertension due to isolated pulmonary artery involvement in large vessel vasculitis

open access: yesRadiology Case Reports, 2020
A 43-year-old woman presented with dyspnea during exertion and lower leg edema. Contrast-enhanced computed tomography images demonstrated extensive proximal narrowing in the right main pulmonary artery with thickening and enhancement.

Persistent Vascular Collagen Accumulation Alters Hemodynamic Recovery from Chronic Hypoxia [PDF]

open access: yes, 2012
Pulmonary arterial hypertension (PAH) is caused by narrowing and stiffening of the pulmonary arteries that increase pulmonary vascular impedance (PVZ). In particular, small arteries narrow and large arteries stiffen. Large pulmonary artery (PA) stiffness

The Wall Eclipsing Sign on Pulmonary Artery Computed Tomography Angiography Is Pathognomonic for Pulmonary Artery Sarcoma

open access: yesPLoS ONE, 2013
Background The objective of this study was to evaluate the imaging characteristics of pulmonary artery sarcoma (PAS) on pulmonary artery computed tomography angiography (PACTA) that can be used to differentiate between PAS and pulmonary thromboembolic ...

PP2Acα Deficiency in Vascular Smooth Muscle Cells Accelerates Aortic Aneurysm and Dissection by Regulating KLF4 Phosphorylation and Ubiquitination

open access: yesAdvanced Science, EarlyView.
Vascular smooth muscle cells (VSMCs)‐specific deficiency of PP2Acα exacerbates aortic aneurysm and dissection (AAD) by promoting phenotypic switching through AKT1‐mediated phosphorylation and stabilization of Kruppel‐like factor 4 (KLF4). Reduced PP2Acα enhances KLF4 ubiquitination resistance, suppressing VSMC contractile genes and accelerating aortic ...

Minimally Invasive Chemical Biopsy Needle with Self‐Wettable Extraction Phase For In Vivo Tissue Sampling During Medical Procedures

open access: yesAdvanced Science, EarlyView.
A new tissue sampling device using an acupuncture needle with bio‐compatible extraction sorbents in the recessed section is developed. The coating material using self‐wettable particles doesn't require solvent activation after sterilization. This device is applied for the anti‐cancer drug concentration monitoring during the in vivo lung perfusion ...

Reoperation of Pulmonary Artery Intimal Sarcoma for Recurrence After Pulmonary Artery Replacement

open access: yesAnnals of Thoracic Surgery Short Reports
Pulmonary artery intimal sarcoma has very poor prognosis, for which radical resection may be difficult. A 68-year-old man with pulmonary artery intimal sarcoma underwent bilateral pulmonary artery resection and replacement.

Cardiovascular Disease Meets Cancer: Exploring the Epidemiology in China and Homotherapy Targeting Intersectional Mechanisms

open access: yesAdvanced Science, EarlyView.
Cardiovascular disease (CVD) and cancer are leading causes of death worldwide, with overlapping risk factors and pathophysiological mechanisms. This review explores shared pathways, including metabolic dysregulation, chronic inflammation, and gut microbiome alterations, highlighting dual‐benefit strategies such as lifestyle modifications and repurposed
