Multimodal computed tomography evaluation before thrombolysis in acute ischaemic stroke

Area of Science:

• Neurology
• Radiology
• Emergency Medicine

Background:

• Thrombolytic therapy for ischemic stroke, such as recombinant tissue plasminogen activator (rt-PA), carries a risk of hemorrhage.
• Current clinical practice often administers rt-PA without knowing the specific ischemic stroke subtype.
• This undiscriminating use is hazardous, particularly in patients without large-artery thromboemboli.

Observation:

• Advances in computed tomography (CT) now allow rapid delineation of stroke pathophysiology.
• Multimodal CT can be performed without delaying rt-PA administration.
• A case study demonstrates the feasibility of this technique in a regional hospital setting.

Findings:

• Multimodal CT enables quick identification of ischemic stroke subtypes.
• This imaging approach can guide the judicious selection of patients for rt-PA therapy.
• The technique is practical for use in regional hospitals.

Implications:

• Improved patient selection for rt-PA therapy can minimize hemorrhage risk.
• This approach supports more precise and effective stroke treatment strategies.
• Wider adoption of multimodal CT can enhance the safety and efficacy of acute ischemic stroke management.
