Purpose
It is aimed to present endovascular treatment of carotid blowout syndrome (CBS) in patients with head and neck cancer.
Methods
A retrospective review was performed on patients with carotid blowout syndrome between 2012 and 2018 in our hospital. A total of ten patients with prior history of head and neck cancer surgery and radiation therapy were investigated with clinical, postoperative and follow-up findings as well as technical outcome. Digital subtraction angiography of the carotid arteries was performed in all the cases for the diagnosis of the source of bleeding. Detachable coils and covered stents were used in endovascular treatment of carotid blowout syndrome. After the procedures, all patients were admitted to the intensive care unit for the follow-up of both hemodynamic and neurologic conditions.
Results
Thirteen diagnostic and endovascular treatment sessions were performed in 10 patients. Seven patients had major surgery for head and neck cancer and all patients were treated with chemoradiotherapy. Head and neck cancers in seven of the ten patients were persistent and pharyngocutaneous fistula developed in five patients. Two patients had impending CBS and eight patients had acute CBS. A total number of 19 vascular lesions in 10 patients were detected and 4 patients had multiple lesions. In three patients, additional endovascular treatment of stent-graft deployment had required due to recurrent hemorrhage after a mean time of 5.33 days (range 1–11 days).
Conclusions
As a conclusion, covered stent application with or without coil embolization is a safe and efficient technique in treatment of CBS secondary to head and neck cancers.
