Persistent, severe post-thrombolysis angioedema: Simple management of a difficult problem

Area of Science:

• Neurology
• Emergency Medicine
• Pharmacology

Background:

• Acute stroke management often involves thrombolysis.
• Post-thrombolysis angioedema is typically mild and self-limiting.
• Severe angioedema, including macroglossia, is a rare complication.

Observation:

• A case of severe orolingual angioedema with persistent macroglossia following thrombolysis for acute stroke is presented.
• The patient experienced significant tongue edema, differing from commonly reported mild cases.
• The severe macroglossia resolved with a conservative management approach.

Findings:

• Post-thrombolysis angioedema can present with life-threatening severity, specifically macroglossia.
• The pathophysiology of thrombolysis-induced angioedema involves complex inflammatory pathways.
• Even severe cases may be manageable with targeted interventions.

Implications:

• Clinicians should be aware of the potential for severe angioedema post-thrombolysis.
• Prompt recognition and management are crucial for potentially life-threatening airway compromise.
• Further research into the spectrum and management of post-thrombolysis angioedema is warranted.
