Rescue therapy for refractory vasospasm after subarachnoid hemorrhage

Area of Science:

• Neurology
• Neurosurgery
• Critical Care Medicine

Background:

• Vasospasm and delayed cerebral ischemia are major causes of death and disability after aneurysmal subarachnoid hemorrhage (aSAH).
• While many vasospasm cases respond to initial treatments, some patients experience persistent symptoms and neurological decline.
• Refractory vasospasm presents a significant clinical challenge in managing aSAH.

Purpose of the Study:

• To review current standard treatments for refractory vasospasm in aSAH.
• To explore emerging novel therapies for managing vasospasm and delayed cerebral ischemia.
• To provide insights into improving cerebral perfusion and mitigating neurological deterioration.

Main Methods:

• Literature review of standard and novel therapeutic strategies.
• Analysis of treatments including hemodynamic augmentation, vascular interventions, and intra-arterial infusions.
• Discussion of emerging therapies for refractory cerebral vasospasm.

Main Results:

• Standard treatments like hemodynamic augmentation and vascular interventions are effective for most vasospasm cases.
• A subset of patients with aSAH requires advanced therapies for refractory vasospasm.
• Novel approaches aim to enhance cerebral blood flow and manage delayed cerebral ischemia.

Conclusions:

• Effective management of vasospasm and delayed cerebral ischemia is crucial after aSAH.
• Clinicians have multiple options for refractory vasospasm, despite varying levels of evidence.
• Further research into novel therapies is needed to optimize outcomes for patients with aSAH.
