[Acquired telangiectases of the lower extremities].

The aim of our study is to place the different forms of telangiectasia of the lower limbs in their clinical categories, before tackling, along with Dr OUVRY, the therapeutic problem with which the phlebologist is daily confronted. The idiopathic telangiectasias of the lower limbs are very common in women, and are considered as simple, but clearly form an entity within the framework of venous pathology : unfortunately we do not have a very precise pathophysiological explanation to provide a basis for prophylaxis, which is still doubtful, or for definitive treatments : nevertheless that is a field for the exercise of the phlebologist's skill. Other types of telangiectasia, which we have mentioned, should call for a search for a general pathology in terms of a complete physical examination from a dermatological viewpoint. More rarely, their precise dermatological category will be that of a dysembryoplasia, while others will be vascular naeval disorders with delayed manifestation. These will all require a specific therapeutic approach.

[Sclerosing treatment of telangiectasis of the lower extremities].

Sclerosant treatment of the telangiectasias should follow several rules : --Sclerosis of varicose veins, then of varicosities, should always precede sclerosis of the telangiectasias. --Small amounts of sclerosant material should be injected at a time, using numerous points of injection. --The author describes the material employed and recommends the use of loop glasses for the treatment of the smallest telangiectasias. --The efficacy of sclerosant treatment is greater than that of other known methods.

[Telangiectases].

The authors have carried out a study of telangectasia in the light of the most recently collected data. They emphasize the ideas already well-known and widely accepted. They consider points which have so far only been discussed and in particular the existence of an arterial intake which, despite all that has been said about it here and there, is still fairly hypothetical. They emphasize the precautions which have to be taken to prevent the recurrence of telangectasia.

[Aetoxisclerol: lst impressions].

Polydocanol is a sclerosing product recently introduced in France. It is less efficient in treating large or medium-sized varicose veins than iodine or trombovar. Because it is pleasant to use, it is mostly advised in the treatment of varicosities and telangiectasias. Like the other sclerosing products that have been used to date, polydocanol can induce allergic reactions in some individuals.

The place of surgery in the treatment of primary varices of the short saphenous vein.

Theories involving the therapy of primary varices of the short saphenous vein are still under discussion today. We try to define the place of surgery between two opposing points of view: that of the partisans of systematic short saphenectomy, and that of the partisans of sclerotherapy on its own. The authors have operated 1341 patients: --between 1961-1971: 968 underwent systematic short saphenectomy, --between 1971-1978: 373 patients underwent eclectic short saphenectomy. The results of the first series gave a 16% failure rate, in the second series there was a 2-3% failure rate. From which we raise the following points: 1. is systematic short saphenous excision always anodine? 2. the criteria for surgical indication to remember are: --clinical: incontinent dilated saphenofemoral junction, ampullary saphenofemoral junction, thick sclerous junction which has resisted sclerosis, saphenal trunk being related to the system of the long saphena; --radiological: wide-gauged saphenofemoral junction, reflux in full channel. Surgery will therefore be reserved for: --the short saphenous axes which are thick, hard, and difficult to sclerose, --wide-necked very ectasic saphenofemoral junctions, --short saphenal axes surrounded by sclerous atrophic cellulitis. From this we take our theory of "experimental" sclerotherapy, the failure of which is the only reason for adopting a surgical solution.

[Deep venous thromboses of the leg. Clinical and therapeutic aspects].

Pulmonary embolism and post-phlebitic syndromes are the most serious risks run by the patient suffering from deep venous thrombosis in the lower limbs. The prognostic of phlebitis depends on how quickly the diagnosis is made, and on the quality of treatment. There is no constant functional or physical symptom. Diagnosis must therfore be readily referable and, if necessary, should be confirmed by paraclinical examinations. Current treatment makes particular use of heparine and haemodilution, always associated with walking and elasto-adhesive compression. Early institution of treatment means that the development of complications can be avoided and gives the patient the best chances of a cure without sequels.

[16 cases of faulty stripping for primary varices].

In answer to the question of knowing whether it is dangerous or not to carry out the excision of intact saphenous veins, the authors define what they mean by faulty strippings. They study 16 personal cases of such strippings, taking their pre-, per-, and postoperative statements from the case-histories. In the discussion they consider the "whys and wherefores" of this kind of faulty treatment, and the mediocre results obtained in medium and long term.

[The external saphenous artery. Preliminary remarks on its importance in phlebology].

An arterial branch, companion of the external saphenous artery, has been described on rare occasions by anatomists. Certain exceptional complications of sclerosant treatment of the varicose external saphenous vein can only be explained by accidental injection of this arteriole. The accidental injection produces cutaneous ischaemia of variable severity and sometimes a partial muscular ischaemia, usually of the internal gemellus. Certain precautions should be taken in order to avoid such an accident. Curative treatment involves both immediate actions and a secondary treatment.

[Should external saphenectomy be routine or eclectic? Results of two series compared].

Based on a comparison between one series where external saphenectomy was routine and another series where external saphenectomy was eclectic, the authors give their preference for excision of the external saphenous when it is clearly diseased, and in this way obtain a 99% success rate. In the discussion, they emphasize that the anatomy of the popliteal fossa can vary, and they attempt to define a plan of management in regard to the external saphenous when it is diseased.

[Echography and sclerotherapy].

Duplex-scanning represents major progress in diagnosis of venous insufficiency. It now permits also amelioration of sclerotherapy, by direct visual reference to the Doppler screen by which means we guide puncture of the vein and control the injection, whether the vein is deep or the location difficult. It permits us also to follow up the results rigorously. The video shows the injection technique by Doppler guidance. The authors report the initial results of a study of 72 consecutive cases.
