title: Thromboxane and prostacyclin formation in patients with deep vein thrombosis.
abstract: The urinary excretion of 2,3-dinor-TxB2 and 2,3-dinor-6-keto-PGF1 alpha (the major urinary metabolites of thromboxane B2 and prostacyclin) was measured in ten patients with confirmed deep vein thrombosis, using specific methods based on gas chromatography - mass spectrometry with deuterium-labelled internal standards. Measurements of these major urinary metabolites makes it possible to monitor the in vivo formation of thromboxane A2 and prostacyclin. The results demonstrate an abnormally high and very variable excretion of 2,3-dinor-TxB2 and 2,3-dinor-6-keto-PGF1 alpha in patients with deep vein thrombosis. This indicate that both thromboxane A2 and prostacyclin are involved in the course of events associated with this disease.
