[Incidence of postoperative deep vein thrombosis in general surgical and urological patients an investigation by means of the 125I-Fibrinogen test in 95 patients withoug prophylaxis (author's transl)].
We present the results of a control group of 95 patients who were thoroughly investigated in a prospective, randomized study, where the efficacy of small doses of s.c. heparin and dextran 40 is checked. The 125I-fibrogen test was used in all patients. 1. 35.8% of the patients develop deep vein thrombosis (DVT) during the first post-operative week. More than half of them show bilateral thrombosis. 2. There is no statistically significant difference in the thrombosis incidence between males and females. 3. 47% of the patients over 60 years develop postoperative DVT. Among those younger than 60 years, only 23% have DVT (P less than 0.025). 4. The DVT incidence in surgery of the colon is 58.3%. 5. Surgery for a malignant disease means probably increased risk for DVT (P less than 0.025). 6. More than half of the patients having a previous history of varicose veins develop postoperative DVT (P less than 0.025). 7. Obese patients are statistically seen not more prone to develop DVT than those of normal body build. 8. Immediately after operation 32.4% of DVT are diagnosed, 24 hrs. later 61.8%. 94% of all DVT are diagnosed up to the third postoperative day. 9. With the exeption of one patient, all DVT develop in the calf veins, 3/4 of all abnormal values were measured in the midcalf region.
