Covered carotid stent controls pseudoaneurysm bleeding but extrudes within 4 months, requiring surgical removal.
Case Report (n=1)
No
This case highlights the rare but severe complication of carotid artery stent extrusion in head and neck cancer patients, demonstrating that surgical removal and artery ligation can be a viable emergency management strategy.
Covered carotid stents may extrude in head-neck cancer; leaves open optimal surveillance and alternatives.
Carotid blowout syndrome is a rare but fatal complication of head and neck cancer. A 62-year-old female patient underwent carotid artery stent implantation for a carotid pseudoaneurysm following multiple surgeries. However, she subsequently presented to the emergency department with bleeding secondary to carotid artery stent extrusion. She underwent emergency surgery, and the carotid artery stent was removed. This case highlights the importance of long-term surveillance of carotid stents in cancer patients who are at risk for tissue necrosis and recurrence.

Beyazal et al. (2026) conducted a case report in 62-year-old female patient with recurrent laryngeal squamous cell carcinoma and carotid pseudoaneurysm treated with carotid artery stent implantation followed by carotid blowout syndrome (n=1). Covered carotid artery stent placement was evaluated on Resolution of bleeding from carotid pseudoaneurysm and presence of stent extrusion requiring surgical removal. Covered carotid artery stent placement successfully controlled pseudoaneurysm bleeding but resulted in thrombosis and extrusion within 4 months in a patient with recurrent laryngeal cancer requiring surgical stent removal without neurological complications.
