[Sclerotherapy with ultrasonography in various risk zones (summary of a video film)].

The sclerosing injection of varicose veins remains a technique which is often essential in the management of a patient with superficial venous insufficiency. The sclerosing injection of high reflux sites, in particular the junctions of the great and small saphenous veins with the deep venous system, is technically difficult. Even great skill and long experience cannot necessarily protect the most hardened phlebologist from a complication which may often be catastrophic.

[Effect of noise on circulatory disorders].

The author reports a dramatic case of severe functional and trophic disorders of the lower limbs which proved to be entirely caused by noise. This case led him to study noise and its repercussions on the vascular system: physical characteristics, methods of measurement, epidemiology of this environmental nuisance, general and vascular diseases produced by the traumatic-vibration syndrome, and study of its mechanism of action. He concludes by calling for interdisciplinary action to combine fundamental research, screening and prevention of the disorders caused by noise.

[Advice of the phlebologist concerning care of the foot, walking and the selection of shoes].

The symbolic potential of the foot explains excessive psychological crystallizations and major patients' resistances to the phlebologist's advices. The author reviews hygiene advices concerning the feet (washing, pedicure, prevention of dermatoses and locking of joints), the three phases of physiological gait (heel gait, plantar and digital gait) and after a historical review of the shoes, exposes the damages caused by heels which are too high and describes the qualities of a physiological shoe.

[2 cases of recurrent deep venous thrombosis with protein C deficiency].

Because of their gravity and the complications involved, repeated deep venous thromboses require everything to be done to produce an aetiological diagnosis, for only this will make a preventive treatment possible. Amongst causes of phlebitis, haemostatic disorders and coagulation factor anomaly should be systematically looked for, as these can sometimes be corrected. Following the discovery of the Antithrombin III deficiency, the protein C deficiency shows clear progress along these lines.
