Atherosclerotic aneurysms of the subclavian artery
Insights
This study details four atherosclerotic aneurysms in normal subclavian arteries of three men, unrelated to thoracic outlet syndrome or trauma. Surgical resection via supraclavicular incision is a safe option for these rare arterial conditions.
Area of Science:
- Vascular Surgery
- Cardiovascular Medicine
- Arterial Disease
Background:
- Atherosclerotic aneurysms of the subclavian arteries are uncommon, particularly in the absence of typical risk factors.
- This report focuses on rare cases without thoracic outlet syndrome or trauma history.
Observation:
- Three adult male patients presented with four atherosclerotic aneurysms of otherwise normal subclavian arteries.
- Symptoms included supraclavicular discomfort, peripheral arterial emboli, or asymptomatic presentation.
Findings:
- Atherosclerotic subclavian artery aneurysms can be safely resected using a supraclavicular incision with medial clavicle resection.
- Median sternotomy is recommended for cases needing more proximal arterial control.
- The case of bilateral atherosclerotic aneurysms is the first reported in surgical literature.
Implications:
- Highlights a rare presentation of subclavian artery aneurysms.
- Provides surgical management insights for vascular surgeons.
- Emphasizes the importance of considering atherosclerosis as a cause of subclavian aneurysms.
Abstract:
The case reports of three adult men, in whom four atherosclerotic aneurysms of otherwise normal subclavian arteries were detected in the absence of thoracic outlet syndrome or a history of trauma, are detailed. Two patients complained of supraclavicular discomfort--one having a history suggestive of peripheral arterial emboli and the other was asymptomatic. These aneurysms can be resected safely using a supraclavicular incision with resection of the medial clavicle. In cases requiring more proximal arterial control, median sternotomy is advisable. Our one patient with bilateral atherosclerotic aneurysms appears to be the first such reported case in the surgical literature.
