[The technic of ambulatory phlebectomy].

Ambulant phlebectomy, according to Muller, is a technique which represents one therapeutic stage in the treatment of a varicosity. Ambulant phlebectomy is a phlebological technique which, preoperatively, requires clinical phlebological and velocimetric examinations, and post-operatively the application of a phlebological compressive bandage. In combination with surgery and sclerotherapy, ambulant phlebectomy results in the total eradication of the varicosity through punctures of 2 or 3 mm, 0.5 cm to several centimetres apart. Ambulant phlebectomy is an efficient, quick and aesthetically pleasing technique.

[Ostial incontinence: sclerosis or resection of the saphenous junction?].

The point of this paper was to compare the long-term results of sclerotherapy and resection/stripping. The authors base their argument on the study of 50 case histories of patients treated by sclerotherapy, and the same number of case histories of patients treated using the resection/stripping of the saphenofemoral junction, followed by sclerotherapy. All these patients were treated between 1965 and 1975 and, at the end of this ten year period, they were considered to need no further treatment, other than routine checks. The results were presented in two comparative series. It would seem that from the fifth year onwards the two methods give results which are appreciably similar, though obtained more rapidly by the resection/stripping method. With these results in mind, the authors mention the general position of the literature on the subject, asking whether it is possible to know whether the two series are really comparable, a fact which would seem certain. They investigate the situation of the patients after five years and deal with the more particular point of isolated ostial incompetence recidivism.

[Familial case of Milroy-Meige-Nonne disease].

Milroy-Meige-Nonne's disease is an exceptional disorder. The authors give an account of a family in which 8 cases were enumerated spread over 4 generations. The clinical pictures given show lymphatic affection of varying severity. The authors take this opportunity to give short historical and anatomical reviews of the disease. Finally they describe current treatment.

[An iatrogenic complication subsequent to an injection of corticoids into the instep].

The authors give an account of their observations of a female patient who was treated for a sprained ankle by an injection of a crystalline suspension of triamcinolone. This therapeutic procedure caused cutaneous and subcutaneous atrophy of the external malleolar region and a strip of atrophy right along the lymph course of the leg. This observation led to bibliographical research and a review of the histological and clinical phenomena characterizing this type of accident. They note that the medico-legal position of the practitioner may be in question.

[The anterior saphenous veins of the thigh].

The authors base their argument on a homogeneous series of 75 patients who, in the course of crossectomies and the stripping of the long saphenousvein carried out by the authors, were given a puncture-phlebectomy of the accessory anterior saphenous vein or veins. Firstly they analyse the clinical characteristics of the incompetence of these veins in the 75 patients. Then, in the discussion, they carry out a closer study of the anterior saphenous veins in the thigh, which have their own anatomical, physiopathological, clinical, and therapeutic characteristics. Without mistaking the role of complementary sclerosis in these cases, they affirm that reliable results are more difficult to obtain with this sort of vein and they suggest peroperative puncture phlebectomy as the results of this seem very encouraging.

[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.

[Epidemiology of varicose veins].

Having recalled the classic works on epidemiology, and having mentioned recent research, the author then considers: 1) Fundamental epidemiological facts. He shows that there is a zone of great varicose occurrence (Western Europe, North America); a zone of mild occurrence (Black Africa, the Far East, the Third World in general); and zones showing discrepancies, (South America, the Mediterranean Basin, India). 2) Explanatory hypotheses concerning the upright posture of Man; prolonged standing; heredity, both clinical (work done by Merlen) and biological (work by Nièbes), affecting the biochemical structure of the venous wall producing degradation of the conjunctive tissue; our way of dressing; the seated position. The terms of a plausible hypothesis must include all the elements defined by Burkitt. 3) Research axes: the role of abdominal hyper-pressure proved by Doppler examination (Folse), provoked by constipation (Cleave) and the idea of an alimentary factor.

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.

The sclerotherapy of telangiectasia.

UNLABELLED: Indications. The sclerotherapy can be used in three sorts of telangiectasia: a) Telangiectasia associated with venous stasis. The practitioner must keep to one rule; sclerotherapy of varicose veins before sclerotherapy of telangiectasia. b) Single telangiectasia. c) Periodic telangiectasia. Technique. The material is: a) sclerosants: chromicized glycerin at 1,11% (Scleremo), polydacanol (Aetoxisclérol) at 0,50%; b) needles: 3/10, 4/10 or 5/10 mm in diameter; c) syringes, 3 ml; d) lenses magnifying X 2. Two important rules: a) progress from the largest to the smallest vessels; b) use little sclerosant at a time and many injections. Other recommendations: 3 or 4 weeks between consultations, compression. RESULTS: telangiectasia usually disappear in a few days. COMPLICATIONS: allergic reactions, cramps, scarring (excessive or extravascular injections), permanent pigmentation (excessive dosage). In conclusion, effectiveness of microsclerosis.

[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.

[Macroscopic and microscopic pathological anatomy of the hemorrhoidal vascular network in hemorrhoidal disease].

In this study, the writers have taken as the basis of their investigation the anatomic and pathological analysis of samples studied as a matter of course after hemorrhoidal operations performed regularly at St Mark's Hospital. They describe their macro- and microscopic findings and, in the discussion, they summarise the development of our knowledge in this field, note the inconsistency between anatomical conclusions and clinical variations, stress the importance of the slipped vascular pad phenomenon, and reject the oft-cited concept of the existence of a corpus cavernosum in the rectum.
