Cerebral hyperperfusion syndrome after endovascular stent graft reconstruction for postirradiated carotid blowout syndrome: a case report

Background: Cerebral hyperperfusion syndrome (CHS) is a failure of autoregulation after revascularization procedure. It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report: We present rare case patient who underwent stent graft implantation to treat postirradiated carotid blowout syndrome. The developed hypertension, focal neurological deficit, and seizures the procedure; neuroimages revealed ipsilateral edema, swelling, increased perfusion. CHS was diagnosed based on clinical radiological findings. recovered gradually receiving supportive care. Conclusion: Owing risk CHS, monitoring for perfusion prevention hypertension suggested undergo placement
