Abstract:
Subclavian arterial aneurysms are relatively rare compared to aortic aneurysms. The common causes of subclavian arterial aneurysms are arteriosclerosis, non-specific inflammation, thoracic outlet syndrome, and trauma. A case of a subclavian arterial aneurysm is reported. The patient was a 57-year-old woman. She had no previous history of hypertension, infection and trauma. She underwent complete resection of the aneurysm and reconstruction of right subclavian artery. Exploration of the aneurysmal wall revealed circumferential ridge which caused stenosis of the right subclavian artery at the orifice of the aneurysm. It has been suggested that a subclavian arterial aneurysm developed as a result of abnormal development of the embryologic right fourth and distal sixth aortic arches.
