Highlights & Basics
- Antiphospholipid syndrome (APS) is the association of persistently elevated antiphospholipid antibodies with a variety of clinical features characterized by thromboses and pregnancy-related morbidity.
- Venous, arterial and microvascular thrombosis can affect any vessel in the body.
- Main treatment goals are management of acute thrombosis and prevention of thrombosis recurrence and pregnancy morbidity.
- Consideration should also be given to the presence of coexistent autoimmune disease in patients with antiphospholipid syndrome.
- Catastrophic disease, which presents as multiple thrombotic events within a short period, often as multiorgan failure, occurs in <1% of patients.
