Interruption of the right middle and lower lobe pulmonary arteries combined with arterial aneurysm formation at the origin of the right subclavian artery branch: a case report
Clinical Report: Interrupted Pulmonary Arteries with Subclavian Aneurysm
Overview
This report details a rare case of a 64-year-old female with interrupted pulmonary arteries in the right middle and lower lobes, complicated by an aneurysm at the right subclavian artery origin. The findings highlight the importance of imaging for diagnosis and the need for individualized treatment strategies.
Background
Interrupted pulmonary artery (IPA) is a rare congenital anomaly, primarily seen in children, but can present in adults with significant clinical implications. This condition can mimic chronic pulmonary embolism and is often associated with pulmonary hypertension and collateral circulation. Understanding its presentation and management is crucial for improving patient outcomes.
Data Highlights
Case study of a 64-year-old female with interrupted pulmonary arteries and subclavian aneurysm.
Key Findings
Patient presented with chest tightness and shortness of breath after physical activity.
CT pulmonary angiography confirmed interruption of the right middle and lower lobe pulmonary arteries.
Extensive collateral circulation was observed, along with pulmonary hypertension.
An aneurysm was detected at the origin of the right subclavian artery.
Clinical Implications
Clinicians should maintain a high index of suspicion for vascular anomalies in patients presenting with unexplained respiratory symptoms. Imaging plays a critical role in diagnosis, and treatment should be tailored based on symptomatology and the presence of complications such as hemoptysis or pulmonary hypertension.
Conclusion
This case underscores the rarity of interrupted pulmonary arteries in adults and the importance of early recognition and appropriate management to enhance patient prognosis.
In a target-trial emulation of more than 600,000 veterans, GLP-1 RA initiators saw fewer new substance use disorders—and patients with existing SUDs had fewer overdoses, hospitalizations, and deaths.
In adults with chronic kidney disease, higher proteinuria and lower estimated glomerular filtration rate are associated with increased risk of incident cognitive impairment.
