Cerebral Hyperperfusion Syndrome After Endovascular Reperfusion Therapy in a Patient with Acute Internal Carotid Artery and Middle Cerebral Artery Occlusions

CHS may lead to unfavorable outcomes after reperfusion therapy for acute ischemic stroke. Recognizing clinical deterioration caused by CHS can be challenging in patients with neurologic disorders of acute ischemic stroke. Therefore, it is important to perform routine monitoring of regional cerebral oxygen saturation by using near-infrared spectroscopy, perform single-photon emission computed tomography promptly to evaluate cerebral blood flow, and maintain strict antihypertensive therapy to prevent CHS after reperfusion therapy.
