With regards to acquired haemophilia, a small series described a spontaneous DVT in a 60 year old woman and in an 80 year old man with splenic marginal zone lymphoma and a proximal leg vein occlusion after a femoral to popliteal by-pass in a 76 year old man [22]; pulmonary embolism developed in a 29 year old man who was on tranexamic acid to minimise bleeding episodes that were managed with recombinant factor VII when occurring acutely [23]: none of these patients had inherited or acquired thrombophilia. Here, F7 is linked to deep vein thrombosis.
