Encouraging results obtained with endovascular treatment of subclavian artery aneurysms (SAAs)¹ led us to use this technique as an alternative to conventional operation in a young female patient with an intrathoracic SAA on the right side complicated by a left-sided cervical aortic arch and agenesis of the left common carotid and vertebral arteries.

	Clinical summary

 
A pulsatile mass was detected in a 38-year-old woman during an echocardiographic assessment of the thyroid. Computed tomographic (CT) scanning showed a 14-mm left-sided cervical aortic arch at the T2 level, a 36-mm enlargement of the ascending aorta, and a normal-sized descending aorta (25 mm). An angiographic study confirmed the presence of a saccular aneurysm of the right subclavian artery with a broad neck, agenesis of the left carotid artery, and narrowing of the aortic arch (Figure 1). Because of the complexity of the patient's vascular abnormalities, we elected to use an endovascular procedure to treat the right SAA only.
