Insights
Aggressive treatment of symptomatic cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) can improve outcomes. This multimodal approach achieved good functional results in 66% of patients with delayed ischemic neurologic deficits.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Symptomatic cerebral vasospasm (CVS) and delayed ischemic neurologic deficits (DIND) affect approximately one-third of patients post-aneurysmal subarachnoid hemorrhage (SAH).
- The natural history of symptomatic CVS is devastating, necessitating aggressive treatment despite limited large-scale clinical trial evidence.
Purpose of the Study:
- To evaluate the effectiveness of a structured, multimodal treatment protocol for symptomatic CVS and DIND following aneurysmal SAH.
- To provide practical guidelines for managing symptomatic CVS based on clinical experience.
Main Methods:
- Retrospective analysis of 79 cases with symptomatic CVS and DIND after aneurysmal SAH.
- Implementation of a multidisciplinary treatment protocol involving neurosurgeons, interventional neuroradiologists, and neurointensive care specialists.
Main Results:
- A good functional outcome was achieved in 66% of patients treated with the multimodal protocol.
- The protocol emphasizes close and rapid multidisciplinary collaboration.
Conclusions:
- An aggressive, structured multimodal treatment regimen is effective in improving functional outcomes for patients with symptomatic CVS and DIND after aneurysmal SAH.
- Multidisciplinary collaboration is crucial for successful management.
Abstract:
Symptomatic cerebral vasospasm (CVS) with delayed ischemic neurologic deficits affects about one third of the patients after aneurysmal subarachnoid hemorrhage (SAH). In spite of the lack of definite evidence of large clinical trials, the devastating outcome of the natural history of symptomatic CVS demands an aggressive CVS treatment in a practically oriented, structured multimodal treatment regimen. With our treatment protocol good functional outcome could be reached in 66% of the patients with symptomatic CVS. This policy requires close and fast multidisciplinary collaboration between neurosurgeons, neuroradiologists, competent in endovascular interventions, and specialists for neurointensive care. We report on our experience with 79 cases with symptomatic CVS and delayed ischemic neurologic deficit (DIND) after aneurysmal SAH. The different treatment options with CVS are reviewed and practical guidelines for a step by step treatment are given.
