[Prevention of postsurgical thromboembolism with small doses of heparin].

The study includes 390 patients of different age, operated for various conditions during the last quarter of 1975, and systematically treated post operatively with heparin (the cases in which heparin was contraindicated were not included). None of the patients developed signs of thromboembolism after the operation. The drawbacks of the method are virtually inexistent as compared to the gravity of postoperative thrombolic complications.
