[Arterial stenosis after renal transplantation].

Attention is drawn to the fact that renal transplants are quite commonly complicated by stenosis of the arterial pedicle. The symptomatology (hypertension, oliguria, fever and gradual loss of renal function) points to the need for angiography. In about 70% of cases, surgical management in the light of the nature of the lesion thus visualised will give good results. Stress is laid on the importance of prophylaxis with platelet anti-clumping agents. Pyramidol appears to offer encouraging results in this connection.
