Summary
Pulmonary artery involvement (PAI) affects 33.8% of aortoarteritis patients, commonly impacting upper lobe branches. PAI can lead to pulmonary hypertension, influencing patient prognosis.
Area of Science:
- Cardiovascular Imaging
- Vascular Medicine
- Rheumatology
Background:
- Aortoarteritis, a large vessel vasculitis, can affect the pulmonary arteries.
- Pulmonary artery involvement (PAI) in aortoarteritis presents diagnostic challenges and impacts patient outcomes.
Purpose of the Study:
- To describe the angiographic findings in patients with aortoarteritis and pulmonary artery involvement.
- To evaluate the diagnostic features and clinical implications of PAI in aortoarteritis.
Main Methods:
- Retrospective analysis of angiographic findings in 133 patients with aortoarteritis.
- Intravenous digital subtraction angiography and conventional arteriography were utilized.
- Detailed assessment of stenosis, occlusion, and distribution of lesions in pulmonary arteries.
Main Results:
- Pulmonary artery involvement (PAI) was identified in 45 (33.8%) of 133 aortoarteritis patients.
- Angiographic findings included stenosis and/or occlusion of segmental, lobar, and subsegmental pulmonary arteries, predominantly in upper lobes.
- Bilateral lesions were more frequent than unilateral; main pulmonary artery involvement was absent. Pulmonary hypertension was noted in 9 of 46 patients.
Conclusions:
- Pulmonary artery involvement is a significant manifestation of aortoarteritis with characteristic angiographic findings.
- PAI, particularly when leading to pulmonary hypertension, adversely affects the clinical course and prognosis of patients with aortoarteritis.
