Lupus anticoagulant, antiphospholipid syndrome and cardiac surgery

Area of Science:

• Cardiology
• Hematology
• Anesthesiology

Background:

• Lupus anticoagulant and antiphospholipid syndrome pose challenges in cardiac surgery.
• Hypercoagulation can occur despite anticoagulation, complicating surgical management.
• Accurate assessment of anticoagulation status is difficult in these patients.

Observation:

• A patient with lupus anticoagulant required aortic valve replacement and coronary revascularization.
• Standard anticoagulation monitoring may not reflect the true in vivo hypercoagulable state.
• Management involved heparin, specialized coagulation assays, and antifibrinolytics.

Findings:

• Successful surgical outcomes were achieved despite the presence of lupus anticoagulant.
• A tailored anticoagulation strategy, including heparin and specific assays, was effective.
• Reduced protamine dosage and tranexamic acid were utilized during the procedure.

Implications:

• This case demonstrates a feasible approach to managing patients with lupus anticoagulant undergoing major cardiac surgery.
• Highlights the need for specialized anticoagulation protocols in patients with antiphospholipid syndrome.
• Suggests potential strategies for optimizing anticoagulation, protamine dosing, and antifibrinolytic use in high-risk surgical patients.
