The following article was reviewed: in the article, o'connor kp, bohnstedt bn.Viabahn stent extrusion into the airway in association with nasopharyngeal squamous cell carcinoma.Interdisciplinary neurosurgery 2019;18.Article 100464.Viabahn was placed in the carotid artery of a patient with nasopharygeal squamous cell carcinoma to treat "carotid blowout syndrome".Six months later, the stent was extruded into the airway and the patient coughed up the stent.The authors conclude: "our patient had stent extrusion into the airway approximately six months after placement.The patient reported to the clinic one week after extrusion without bleeding or symptomatology.Ct neck angiography demonstrated that the vessel thrombosed from the common carotid at the level just off the aortic arch to the internal carotid at the level of the cavernous sinus.The patient also had sufficient collateral flow from the contralateral side which allowed avoidance of neurological symptoms secondary to brain ischemia.We believe this to be a unique situation following vessel protection.The patient experienced vessel occlusion with stent extrusion.".
