Bilateral Renal Vein Thrombosis due to Elevated Factor VIII Levels.

Recent evidence has shown that high level of factor VIII is associated with increased risk of thromboembolism. High factor VIII levels are associated with a seven-fold increase in the risk of venous thrombosis. Renal vein thrombosis is usually associated with nephrotic syndrome, procoagulant state or oral contraceptive pills. We report a case of a lady who presented with bilateral renal vein thrombosis due to high factor VIII levels and oral contraceptive pills (OCP) use.
