The early diagnosis and effective treatment of cerebral vasospasm after SAH remain complex and challenging. While TNS at an effective dose might increase cerebral perfusion and help to prevent vasospasm and DCI, we were not able, in this pilot study, to highlight it by using MRI assessment at 3 months. Further studies are required to determine its efficacy, risk-benefit ratio and efficiency. In parallel, due to an unexpectedly high frequency of vasospasm in asymptomatic patients, we recommend systematic CTA/PCT for the early management of patients with aneurysmal SAH. A positive CTA/PCT finding will help to identify and stratify patients who should be carefully considered for treatment intensification, including more aggressive preventive management of potential clinical vasospasm and, consequently, early endovascular therapy.
