Induced Hypertension for Delayed Cerebral Ischemia after Aneurysmal Subarachnoid Hemorrhage—A German Nationwide Survey

Delayed cerebral ischemia (DCI) remains a major cause of morbidity after aneurysmal subarachnoid hemorrhage (aSAH). Induced hypertension (IH) is frequently used to improve cerebral perfusion in patients with DCI, with current practice primarily supported by observational evidence with inconsistent guideline recommendations. We conducted a nationwide survey to assess current institutional approaches to IH in the management of DCI after aSAH in Germany. An 11-item web-based questionnaire was distributed via LimeSurvey® between May and October 2025 to neurological and neurosurgical departments in Germany involved in the treatment of aSAH. The survey assessed institutional approaches to IH, monitoring and imaging strategies, and DCI treatment. Overall, 60/132 departments (45
