Fibromuscular dysplasia of the right subclavian artery
European Journal of Radiology
|November 1, 1983
Insights
This report details a rare case of arterial fibromuscular dysplasia affecting the right subclavian artery, causing limb claudication. Surgical bypass successfully corrected the multifocal stenosis, restoring blood flow.
Area of Science:
- Vascular Surgery
- Cardiovascular Medicine
- Interventional Radiology
Background:
- Fibromuscular dysplasia (FMD) is a non-atherosclerotic vascular disease.
- Arterial FMD can affect various arteries, leading to stenosis, occlusion, or aneurysms.
- Subclavian artery involvement in FMD is less common but can cause significant upper extremity ischemia.
Observation:
- A patient presented with claudication symptoms in the affected limb.
- Diagnostic angiography revealed multifocal stenosis in the proximal right subclavian artery.
- The imaging findings were characteristic of fibromuscular dysplasia.
Findings:
- The case highlights an uncommon presentation of arterial fibromuscular dysplasia.
- Multifocal stenosis of the right subclavian artery was confirmed.
- Surgical intervention via a carotido-subclavian bypass graft was performed.
Implications:
- Successful surgical correction of subclavian artery FMD can alleviate ischemic symptoms.
- This case underscores the importance of considering FMD in the differential diagnosis of limb claudication.
- Vascular reconstruction techniques offer effective treatment for complex arterial anomalies.
Abstract:
The case of an uncommon form of arterial fibromuscular dysplasia is reported. The anomaly was located in the right subclavian artery. Claudication of the affected limb was the presenting symptom. Angiography was diagnostic in visualizing typical multifocal stenosis of the proximal portion of the right subclavian artery. Complete surgical correction was performed by establishing a carotido-subclavian by-pass graft.
