VENOUS THROMBOSIS AND HYPERHOMOCYSTEINAEMIA

We report a 39-year-old man with a history of recurrent deep venous th rombosis (DVT) whose only laboratory-identified risk factor was modera te hyperhomocysteinaemia. After being lost to follow-up without interv ention, he presented with another DVT: Apart from standard anticoagula tion therapy he received vitamin supplementation (folate and vitamin B -12), which normalised his elevated plasma homocysteine level. Moderat e hyperhomocysteinaemia is a relatively common abnormality and an easi ly modifiable risk factor for DVT.
