Acute aortic thrombosis in antithrombin III deficiency
JAMA
|May 1, 1981
Summary
Antithrombin III deficiency can cause acute aortic thrombosis in young patients. Warfarin sodium therapy normalized antithrombin III levels in two reported cases, suggesting its consideration for arterial thrombosis.
Area of Science:
- Cardiovascular Medicine
- Hematology
- Genetics
Background:
- Antithrombin III (ATIII) deficiency is a rare inherited condition predisposing individuals to venous thromboembolism.
- Arterial thrombosis, particularly aortic thrombosis, is an uncommon manifestation of ATIII deficiency.
Observation:
- Two young patients presented with acute aortic thrombosis.
- Both patients exhibited significantly reduced antithrombin III levels.
Findings:
- Antithrombin III levels normalized in both patients following treatment with warfarin sodium.
- This suggests a potential therapeutic role for warfarin in managing acute aortic thrombosis associated with ATIII deficiency.
Implications:
- Antithrombin III deficiency should be considered in the differential diagnosis of acute arterial thrombosis, especially in young individuals.
- Early identification and appropriate anticoagulation, such as with warfarin, may be crucial for managing this rare complication.
