Recent advances in neurointerventional strategies, including the endovascular thrombectomy (EVT) and carotid artery stenting (CAS) techniques, have revolutionized ischemic stroke management by expanding treatment options and improving patient outcomes. Conventional transcranial Doppler (TCD), a tool long used in stroke care, lacks the ability to directly visualize vessels, limiting its application. However, TCD is still valuable as a non-invasive adjunctive monitoring strategy in neurointervention, owing to its ability to provide continuous, real-time bedside hemodynamic monitoring, offering precise numerical data, high repeatability, low invasivity, and no risk of radiation or contrast agent exposure. This unique capacity for continuous monitoring is particularly useful when integrated with artificial intelligence (AI) for data interpretation. This review explored the potential of TCD as an adjunct tool in neurointervention, emphasizing its roles in EVT and CAS. In EVT, TCD aids to evaluate post-recanalization blood flow, predicting clinical outcomes by assessing cerebral autoregulation and collateral status, and identifying patients at risk of hyperperfusion syndrome. TCD can further aid in stroke risk assessment in patients with asymptomatic carotid stenosis, as well as the selection of candidates for CAS by detecting microemboli, assessing the cerebrovascular reserve, and evaluating ophthalmic artery flow reversal. It can also be used to detect cerebral hyperperfusion following CAS. The utility of TCD extends to other endovascular procedures beyond neurointerventions, where automated and AI-assisted devices enhance its real-time intraoperative neuromonitoring abilities. This review discusses the potential of TCD to refine patient selection, predict outcomes, and enhance the efficacy of neurointerventional procedures.

Surfer's myelopathy is a rare nontraumatic spinal cord disorder associated with surfing. This study reports three patients with surfer's myelopathy. All patients were young males who were previously healthy and first-time surfers at the onset of their symptoms. They developed the symptoms while surfing or shortly thereafter, presenting with lower back pain followed by an acute myelopathy. Spine magnetic resonance imaging showed T2 hyperintense cord lesion. Since the number of surfers is increasing in Korea, awareness of surfer's myelopathy is necessary for early recognition and proper management.

Background: and Purpose We aimed to determine whether the care process and outcomes in patients with acute stroke who received recanalization therapy changed during the outbreak of coronavirus disease 2019 (COVID-19) in South Korea. Methods: We used data from a prospective multicenter reperfusion therapy registry to compare the care process including the time from symptom onset to treatment, number of treated patients, and discharge disposition and treatment outcomes between before and during the COVID-19 outbreak in South Korea. Results: Upon the COVID-19 outbreak in South Korea, the number of patients receiving endovascular treatment to decrease temporarily but considerably. The use of emergency medical services by stroke patients increased from 91.5% before to 100.0% during the COVID-19 outbreak (p=0.025), as did the median time from symptom onset to hospital visit [median (interquartile range), 91.0 minutes (39.8–277.0) vs. 176.0 minutes (56.0–391.5), p=0.029]. Furthermore, more functionally dependent patients with disabilities were discharged home (59.5% vs. 26.1%, p=0.020) rather than staying in a regional or rehabilitation hospital. In contrast, there were no COVID-19-related changes in the times from the hospital visit to brain imaging and treatment or in the functional outcome, successful recanalization rate, or rate of symptomatic intracerebral hemorrhage. Conclusions These findings suggest that a prehospital delay occurred during the COVID-19 outbreak, and that patients with acute stroke might have been reluctant to visit and stay in hospitals. Our findings indicate that attention should be paid to prehospital care and the behavior of patients with acute stroke during the COVID-19 outbreak.
