Subclavian Artery Aneurysms: Rare but Serious Risks
Subclavian artery aneurysms, though rare, pose significant risks. These occur in the subclavian arteries, which supply blood to the arms and branch to the brain. Understanding their formation and cause synonym is crucial for early detection and treatment.
Subclavian arteries, two in number, originate from the brachiocephalic trunk on the right and the aortic arch on the left. They are divided into three parts relative to the scalenus anterior muscle and extend about two centimeters above the clavicle. These arteries branch into vertebral arteries, crucial for brain oxygenation.
Aneurysms in subclavian arteries can develop due to various reasons. Post-traumatic injuries, thoracic outlet obstruction, and arteriosclerosis are some of the known causes. Less commonly, atherosclerosis, thoracic outlet syndrome, connective tissue disorders, infections, and other traumas can also lead to these aneurysms.
Subclavian artery aneurysms, though uncommon, can have severe consequences if left untreated. Understanding their causes and anatomy is vital for prompt diagnosis and management. Further research into less common causes can enhance prevention and treatment strategies.
