To the Editor:

Vascular access site thrombosis is a major cause of morbidity in patients receiving hemo­dialysis. The role of hypercoagulable states in recurrent vascular access site thrombosis remains poorly understood. We herewith report a case of recurrent thrombosis of vas­cular access in an elderly female patient on hemodialysis.

We report on a 58-year-old female patient who was on maintenance hemodialysis (HD) thrice weekly for the previous four years. During this period, she had repetitive throm­botic complications of her vascular access resulting in necrosis of the distal fingers. The problem persisted despite warfarin sodium therapy. A detailed search for any local factors contributing to this complication did not yield any positive results. Concentrations of factors II, V, VII, VIII, X, XI, antithrombin III, protein C, protein S, anti-cardiolipin antibodies type M and G and lupus antico­agulant antibodies were investigated. The only abnormality found was high levels of factor VIII (FVIII). She died two years later due to septicemia secondary to infection of the necrosed fingers.

Similar cases have been published in literature among HD patients.[1],[2] Factor VIII is normally bound to the von Willebrand factor. Unbound Factor VIII may play a role in recurrent venous thrombosis.[3] The use of bio-incompatible dialyzers (like cuprophane) is associated with changes of Factor VIII­related von Willebrand concentration and significant platelet activation and loss.[4],[5] Increased levels of Factor VIII is incriminated in causing recurrent thrombosis in non­dialysis patients also.[6],[7]

Hypercoagulable states are common in patients with recurrent vascular access site thrombosis. Increased factor VIII is a frequent cause in these situations, in addition to "traditional" risk factors.
