Prophylaxis of venous thromboembolic complications in patients operated on abdominal organs

: Comparative analysis of results of venous thromboembolic complications prophylaxis (deep vein thrombosis--DVT1, pulmonary artery thromboembolism--PAT) in patients operated on abdominal organs during two periods--from 1980 to 1983 (when traditional methods were used--leg bandage, rarely--0.25-0.5 g aspirin 1-2 times a day 5-8 days after surgery) and from 1984 to 1998 (when in the operated patients with moderate, high and very high risk of DVT and PAT combination of physical methods of blood flow acceleration in leg deep veins with drugs was used--minidoses or individually selected doses of non-fractionated heparin, low-molecular heparin, dextrans) was carried out. Compared with first period the rate of manifested DVT decreased from 1 to 0.3%, fatal PAT (percentage of those who died from all operated)--from 0.3% in 1982-1983 to 0.026% in 1998, i.e. more than 10 times. In some years (1992-1993) there were no lethal outcomes of PAT.
