| Abstract
| - Purpose. The purpose of this study was to review the use of covered stents in patients with squamous cell carcinoma of the head and neck threatening bilateral neurovascular structures. Methods. The radiology information system was searched for all patients with bilateral head and neck carcinoma treated with covered stents in the carotid vasculature from 2006 through 2009. Five patients (one woman) of mean age 60.5 years (range 45-69) were identified. All had carotid blowout syndrome after treatment for primary squamous cell carcinoma of the head and neck with subsequent tumor recurrence or metastases immediately threatening bilateral carotid vasculature. Covered stents were placed. Long-term follow-up included clinical progress, verification of stent patency and detection of tumor progression via ultrasound or contrast-enhanced CT after the first month and then every 3-6 months. All patients were maintained on antiplatelet medication after treatment. Results. Covered stents were safely deployed in all patients. Mean survival was 5 months with one outlier surviving for 3 years. There were no subsequent uncontrollable hemorrhages. Conclusion. The use of covered stents for avoidance of catastrophic hemorrhage following treatment in patients with head and neck tumors with bilaterally threatened carotid arteries was successful.
