TVPTVP

• The precise number of people affected by DVT/PE is unknown, but estimates range from 300.000 to 600.000 (1 to 2 per 1000, and in those over 80 years of age, as high as 1 in 100) each year in the United States.

• Estimates suggest that 60.000-100.000 Americans die of DVT/PE (also called venous thromboembolism).

• Among people who have had a DVT, one-half will have long-term complications (post-thrombotic syndrome)

Direct comparisons of proportional effects of different antiplatelet regimens on deep venous thrombosis and on pulmonary embolism

BMJ 1994;308:235-246

Proportional effects of antiplatelet therapy on numbers of patients observed to have pulmonary embolism in trials that sought venous

thrombosis systematically after general and orthopaedic (traumatic and elective) surgery and in high risk medical patients

BMJ 1994;308:235-246

  15 April 2000;Volume 355, Issue 9212, Pages 1295 - 1302,

Aspirin reduces the risk of pulmonary embolism and deep-vein thrombosis by at least a third throughout a period of increased risk.

There is now good evidence for considering aspirin routinely in a wide range of surgical and medical groups at high risk of venous thromboembolism.

Triflusal

• selective inhibition of TxB2 and platelet cyclo-oxygenase activity

• does not interfere significantly with endothelial synthesis of prostacyclin via the cyclooxygen ase-2 pathway.

• increases nitric oxide synthesis by neutrophils, and decreases the activity of nuclear transcription factor NF-B more than aspirin does

• inactivates intraplatelet phosphodiesterase • potentiates the antiaggregant effect of cAMP and

cGMP • These pharmacological differences make triflusal

potentially more effective and safer than aspirin

Triflusal appears to provide prevention of thromboembolic risk to patients who have undergone hip surgery, particularly total hip replacement

The amount of blood transfused was significantly reduced in triflusal compared with aspirin recipients who underwent hip surgery.

Risk of haemorrhage was also reduced in patients receiving triflusal versus aspirin.
