It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report: We present a rare case of a patient who underwent stent graft implantation to treat postirradiated carotid blowout syn-drome. The patient developed hypertension, focal neurological deficit, and seizures after the procedure; neuroimages revealed ipsilat-eral cerebral edema, swelling, and increased cerebral perfusion. CHS was diagnosed based on clinical and radiological findings. The patient recovered gradually after receiving supportive care. Conclusion: Owing to the risk of CHS, monitoring for cerebral perfusion and prevention of hypertension is suggested for patients who undergo stent graft placement for postirradiated carotid blowout syndrome.Case report | Cerebrovascular circulation | Hypertension | Stents[SDGs]SDG3journal article10.18700/jnc.2200592-s2.0-85145611732https://api.elsevier.com/content/abstract/scopus_id/85145611732
