Decompressive craniectomy after intravenous tissue plasminogen activator administration for stroke

Area of Science:

• Neurology
• Neurosurgery
• Vascular Neurology

Background:

• Intravenous tissue plasminogen activator (IV tPA) is a standard treatment for acute ischemic stroke.
• The role of decompressive craniectomy (DC) following IV tPA for stroke is not well-established.

Purpose of the Study:

• To evaluate the safety and outcomes of decompressive craniectomy (DC) in patients who received IV tPA for acute ischemic stroke.
• To compare outcomes between patients undergoing DC after IV tPA and those undergoing DC without prior IV tPA.

Main Methods:

• Retrospective review of patients who underwent DC for malignant hemispheric infarction.
• Comparison of 20 patients who had DC after IV tPA with 20 patients who had DC without prior IV tPA.

Main Results:

• No significant differences in patient characteristics between the two groups.
• Similar rates of new or worsening intracranial hemorrhage (10% in each group).
• Comparable rates of functional outcomes (modified Rankin Scale scores 4-6, 5-6, and 6) between groups.

Conclusions:

• Decompressive craniectomy (DC) may be a safe and effective surgical option for managing space-occupying edema after IV tPA in acute stroke patients.
• The findings suggest that prior IV tPA administration does not negatively impact the safety or outcomes of DC.
