[Role of the external saphenous vein in repeat surgery of primary varicose veins of the lower limbs].

Between January 1968 and June 1978, we required to carry out 170 repeat operations for primary varicose veins of the lower limbs. In 34 operations (21.9% of cases) the re-operation involved a surgical procedure on the external saphenous: --in 6 cases, isolated ligature of the arch, --in 28 cases, stripping of the short saphenous. In our practice surgical reoperation is only indicated when there is a substantial point of leakage between deep and superficial systems. Residual varicosities after surgery require simple post-operative sclerosis. Surgery to the short saphenous is carried out in various circumstances; a) Where the initial operation involved an error in technique: Wrongly sited ligature of the arch (5 cases). This occurs less frequently than in the cases of the internal saphenous . b) Where the first operation was defective by reason of a tactical error: The short saphenous had not been recognized as responsible for varicose veins and had been ignored. Where several years after an operation on the long saphenous, insufficiency developed in the short saphenous and required treatment in its turn. Preoperative assessment involved phlebography and a Doppler examination in the majority of cases. The results are difficult to assess since in nearly two thirds of the cases, surgery to the external saphenous was combined with a further surgical procedure on the internal saphenous.

[Current role of surgery in chronic venous diseases].

Non invasive explorations of chronic venous disease, particularly echo-doppler techniques, have greatly improved our understanding of the underlying pathophysiological mechanisms. The findings of the physical examination are however still the basis of all indications for surgery. The most frequently performed procedures involve treatment of superficial venous insufficiency. Classical stripping of the large superficial veins with crossectomy has largely been replaced by more individualized procedures. The long-term effectiveness of certain revolutionary methods such as the Chiva procedure have not yet been proven. Indications for surgery of the perforating veins is a matter of debate but could benefit from the development of less traumatic endoscopic techniques. Surgery of deep vein insufficiency is another field of development. The follow-up in recently reported series is now long enough for an assessment of the therapeutic value of these procedures. Deep vein surgery has given a variable degree of success for post thrombotic syndrome but its effectiveness is proven in Primary deep vein insufficiency.

[Oral and dental health status in a population of schoolchildren aged 5 to 15 years in Wallis].

This study was performed in 1992 with three aims: to assess precisely the prevalence of dental carries in the child population of Wallis Island; to evaluate the need for dental care; and create a database allowing the oro-dental status to be followed and the effectiveness of preventive programmes to be assessed. The total population of the Wallis Islands according to the 1990 (the most recent) census was 8,973 living in twenty villages. The population was classified into four ethnic groups: Wallisian (94.4%), Futunian (1.2%), European (3.9%) and miscellaneous (0.5%). The lifestyle of the population is traditional and there is virtually no manufacturing, overseas trade or tourism. The population of Wallis Island is young, with 56.6% of the population under 20 years old. Almost all the children attended school from the age of 6 to the age of 19 [3]. Half the Island's children (n = 1407) between the ages of 5 and 15 years old were classified into 11 age groups and were examined. Children from all schools were included in the study group which was representative of the child population of Wallis Island (94.4% were Wallisian) (table 1). The study was performed according to the 1988 WHO guidelines [4] and Cahen [5]. At age 5, a mean of 3.26 teeth had erupted. The permanent dental set (other than the 3rd molars) were present by age 12 years in virtually all cases. The percentage that had carrie-free permanent teeth were 89.9% at age 5, 59.9% at age 6, 22% at age 12 and only 13.4% at age 15.(ABSTRACT TRUNCATED AT 250 WORDS)

[The contribution of Doppler echography in the diagnostic and therapeutic plan in chronic venous insufficiency surgery].

Indications for duplex scan in venous surgery. Vascular surgeons are led to request Duplex Scan examination of patients with chronic venous insufficiency in a number of circumstances: A) To obtain information supporting the diagnosis and treatment plan: Chronic venous insufficiency may be due to isolated superficial venous insufficiency or (and) deep venous insufficiency (post-thrombotic syndrome, primary deep valvular insufficiency, congenital malformation). In practice, Duplex Scan examination of the deep venous system is indicated whenever the patient's history is suggestive of deep venous thrombosis or the clinical status is stage 2 or 3 (Ad Hoc Committee classification). In patients with reflux in the popliteal fossa, Duplex Scan is helpful because physical examination and Doppler cannot correctly differentiate short saphenous insufficiency, gastrocnemius insufficiency and reflux in the popliteal-tibial axis, especially as these physiopathologic mechanisms may be associated. In patients with atypical varices, Duplex Scan can demonstrate: Absence of reflux in the greater saphenous vein-femoral vein termination or the short saphenous vein-popliteal vein termination. Varices in the lateral or posterior thigh. In patients with varicose vein thrombosis, Duplex Scan can reveal: The extent of any association with deep venous system. The extent of superficial venous thrombosis. When the results of varicose vein surgery are unsatisfactory, Duplex Scan can determine whether a redo surgery is justified: Persistence of a major leak between the deep and superficial venous system usually prompts redo surgery. Less often, recurrence is due to primary deep valvular insufficiency, in which case valvuloplasty may be indicated.(ABSTRACT TRUNCATED AT 250 WORDS)
