Abstract
Carotid stenosis after neck irradiation is a well-described entity. A 78-year-old man presented with left eye amaurosis fugax 11 years after radical neck dissection and neck irradiation for mucoepidermoid carcinoma. The patient underwent carotid artery stenting for a high-grade stenosis of the left internal carotid artery. Twenty months after the procedure, a pulsatile neck mass developed with intermittent arterial bleeding. After control of the bleeding, he underwent resection of the left carotid bifurcation, including the indwelling stent and reconstruction with a saphenous vein interposition graft. A pectoralis myocutaneous flap was used for wound closure. In this case, localized infection of the stented carotid artery led to mycotic degeneration, pseudoaneurysm formation, and erosion to the skin surface. As carotid artery stenting becomes more widely used, previously unreported late complications associated with this procedure are likely to become apparent, and continued close follow-up is warranted.
