[Effect of extended anticoagulant therapy on long-term results of bypass for arterial occlusive disease].

Data selected from the questionnaire supplied by the 14 centres of vascular surgery have been analysed. All operated patients have been followed-up for 5 years. An analysis revealed that long-term oral anticoagulant therapy following vascular grafting statistically significantly improved the outcome of surgery in comparison with patients who have not been given oral anticoagulants. There has been no such a relationship, if antiaggregation agents had been used for the treatment.
