Hemarthroses and warfarin: joint destruction with anticoagulation

Area of Science:

• Orthopedic Surgery
• Hematology
• Vascular Medicine

Background:

• Anticoagulant therapy poses risks for patients, including potential bleeding complications.
• Superior vena cava syndrome (SVCS) is a serious condition often linked to thrombosis or malignancy.
• Recurrent hemarthrosis can lead to significant joint damage and chronic pain.

Observation:

• A 56-year-old male patient presented with a six-year history of recurrent right shoulder hemarthroses and SVCS.
• The patient's intermittent symptoms had resulted in marked destructive changes in the right shoulder joint.
• Arthroscopy provided pathological evidence of the underlying mechanism causing the arthropathy.

Findings:

• The patient's presentation suggests an unusual mechanism of arthropathy linked to anticoagulation and potential occult bleeding.
• Destructive arthropathy of the shoulder was confirmed pathologically.
• Superior vena cava syndrome co-occurred with shoulder hemarthroses, indicating a complex clinical presentation.

Implications:

• Close monitoring for symptoms of occult bleeding is essential in patients receiving anticoagulant therapy.
• This case highlights the importance of considering bleeding complications in patients with unexplained joint destruction and vascular syndromes.
• Further research may elucidate the precise link between anticoagulation, SVCS, and shoulder arthropathy.
