Innominate artery aneurysm with thrombus: detection by two-dimensional echocardiography
Journal of the American College of Cardiology
|August 1, 1983
Summary
A 51-year-old man experienced forearm and hand ischemia due to an innominate artery aneurysm. Two-dimensional echocardiography detected a mobile thrombus missed by angiography, highlighting its value in assessing embolic risk.
Area of Science:
- Vascular surgery
- Diagnostic imaging
- Cardiology
Background:
- Innominate artery aneurysms can lead to serious complications like limb ischemia.
- Accurate diagnosis is crucial for effective treatment and risk stratification.
- Traditional angiography may not always reveal all pathological elements within aneurysms.
Observation:
- A patient presented with claudication and ischemia of the right forearm and hand.
- A saccular aneurysm of the innominate artery was identified.
- A pedunculated, mobile thrombus within the aneurysm was visualized by 2D echocardiography.
Findings:
- Two-dimensional echocardiography successfully identified the innominate artery aneurysm and an associated mobile thrombus.
- Aortic arch angiography failed to visualize the thrombus.
- The findings suggest 2D echocardiography's utility in detecting intracardiac masses and aortic aneurysms.
Implications:
- Two-dimensional echocardiography may improve the detection of embolic sources in patients with aortic aneurysms.
- This imaging modality could be vital for identifying patients at high risk of embolization.
- Enhanced visualization aids in surgical planning and patient management for innominate artery aneurysms.
