Neuroprotection from the collateral perspective

Area of Science:

• Neurology
• Vascular Biology
• Stroke Medicine

Background:

• Neuroprotection for acute ischemic stroke has been researched for over 50 years without therapeutic success.
• Existing research on the ischemic cascade has largely ignored the critical role of collateral circulation.
• Advances in multimodal imaging and revascularization options highlight the importance of vascular factors.

Purpose of the Study:

• To review the role of collateral circulation in acute ischemic stroke pathophysiology.
• To emphasize the significance of vascular aspects in neuroprotection strategies.
• To explore how collateral perspective influences the future of neuroprotection.

Main Methods:

• Review of existing literature on ischemic stroke, neuroprotection, and collateral circulation.
• Analysis of the impact of collateral perfusion on the ischemic penumbra and drug delivery.
• Synthesis of findings regarding multimodal imaging and revascularization techniques.

Main Results:

• Collateral circulation is a fundamental, yet often overlooked, factor in ischemic stroke.
• Collateral perfusion defines the ischemic penumbra, affects drug delivery, and impacts clinical outcomes.
• Emerging evidence underscores the importance of vascular aspects and collateral dependence in neuroprotection.

Conclusions:

• Future neuroprotection strategies for acute ischemic stroke must incorporate the role of collateral circulation.
• Combined approaches of revascularization and neuroprotection, considering collateral status, are essential for therapeutic success.
• Addressing the collateral perspective is crucial for advancing neuroprotection in acute ischemic stroke treatment.
