Acute Ischemic Stroke With Mild Symptoms-To Thrombolyse or Not to Thrombolyse?

Area of Science:

• Neurology
• Emergency Medicine
• Clinical Therapeutics

Background:

• Minor stroke management presents a therapeutic dilemma due to the risk of hemorrhage from acute thrombolytic therapy versus stroke severity.
• Approximately 30% of patients with minor stroke symptoms experience long-term disability.
• Current guidelines often advise against thrombolysis for non-disabling minor strokes due to limited evidence.

Purpose of the Study:

• To review current literature and evidence on managing minor stroke.
• To specifically evaluate the role and efficacy of intravenous (IV) thrombolysis in minor stroke cases.
• To explore definitions, pre-hospital recognition, and neuroimaging in minor stroke management.

Main Methods:

• Systematic review of existing literature and clinical evidence.
• Analysis of neuroimaging techniques for identifying potential treatment responders.
• Discussion of stroke definitions, pre-hospital recognition, and unknown onset scenarios.

Main Results:

• Evidence for IV thrombolysis in minor stroke is limited, leading to current guideline restrictions.
• Advanced neuroimaging may help identify patients with minor stroke who are likely to benefit from thrombolysis.
• Further research is needed to clarify the optimal management strategies.

Conclusions:

• The decision to use IV thrombolysis in minor stroke requires careful consideration of risks and benefits.
• Advanced imaging holds promise for personalizing treatment decisions in minor stroke.
• Ongoing research aims to provide clearer guidance for managing minor stroke patients.
