Treatment of a Case of Common Carotid Artery Pseudoaneurysm That Developed after Surgery for Hypopharynx Cancer by Covered Stent Placement

“…2) Intraaneurysmal embolization may be considered as a measure to achieve temporary hemostasis, but long-term occlusion cannot be expected by this procedure. 2) Bypass surgery and artificial vessel replacement should be evaluated, 3) but they are difficult to perform as additional procedures to the neck that has been previously operated on or irradiated. 1,2) Therefore, endovascular treatment using a covered stent has recently emerged as the first choice.…”

“…Surgical treatment for CBS is highly invasive, and its outcomes are poor. [1][2][3] However, the outcomes of endovascular treatment for CBS have been reported to be more favorable compared with those of other treatments. 1,4) In the case reported here, we could prevent CBS by covered stent (Fluency Plus; Bard Peripheral Vascular, Tempe, AZ, USA) placement for common carotid artery pseudoaneurysm following treatment for hypopharynx cancer.…”
