[Arteriovenous fistula for vascular access in childhood leukemia. Value of microsurgical technique (author's transl)].

Acute leukemia are now in progress with intensive and prolonged polychimiotherapy but such medicine is difficult to manage because veins are rapidly unserviceable. In order to simplify hematological treatment and psychological approach of this patients we have constructed arterio-venous fistula in children with malignancy. The operation of choice is a subcutaneous cephalic-vein to-radial-artery arterio-venous fistula on the fore arm at the distal part. 103 of this vascular access procedures are performed in 93 children and in infants weighing less than 10 kg: 57 are performed without magnification, 46 with the aid of operative microscope. The comparative study of this two procedures show that microsurgical technique is necessary to improve results, especially in the youngest patients. This vascular access are well accepted by the children and his families, and very useful for the medical staff.

[A new orthopedic apparatus for the treatment of congenital equinovarus clubfoot. The active-passive articulated splint. Critical study propos of 72 cases treated in our department].

The authors present a new equipment for orthopaedic assesment of club-foot. This "dynamic splint" aims to produce a self-correction of the deformity by the infant at time of each movement of his lower limb. With regard to 72 such deformities, concerning 47 children, they record the results after an average follow-up of more than 2 years. Criterions of results, clinical and chiefly radiological, more objectives, are classified into 3 parts : correction of varus of the foot, correction of adduction of the hind-foot, correction of equinus.

[Morphometry of the femoral head in the rabbit. Surface appearance of the acetabulum after femoral prosthesis].

An anatomical study has been achieved on 42 upper extremities of adult rabbit's thigh bones. Three types of prostheses have been perfected in order to analyse the reactions of the cartilage and of the subchondral bone when confronted with these implants. The animals were sacrificed at different intervals. The state of the acetabulum surface has been studied according to macroscopic and microscopic criteria. Three methods converge and agree in showing an arthrosis type of reaction with regard to the non operated controlateral articulation.

Familial extrahepatic biliary atresia.

Only a small number of cases with familial extrahepatic biliary atresia, suggesting a recessive autosomal inheritance, have been reported. However, the cases reported in twins are consistent with an acquired disease. Here the case of two brothers with familial atresia of the extrahepatic biliary system is studied. Diagnosis was confirmed by laparotomy and histologic study of biliary fibrous remnants. In the present cases parental consanguinity might suggest a recessive autosomal inheritance. However, clustering of cases in a family might also suggest a common exposure to responsible factors not so far identified.

Current surgical treatment of post-operative eventrations.

A series of 247 post-operative eventrations (POE) is reported with a study of general features, such as: patients' sex and age, size, location and etiology of POE (serial laparotomies, parietal sepsis), classic predisposing factors. Pre-operative preparation involved the use of Goni-Moreno progressive pneumo-peritoneum in 18.5% of patients. The procedures used were: parietal suturing (25%), the same plus a dacron buttress (6%), or a large reinforcing Dacron Mesh prosthesis (67%). Early sepsis was slightly more frequent after Dacron use. The incidence of predisposing factors in this field is reported. Other complications of the use of Dacron Mesh are studied (hematomas, skin necrosis). The post-operative uncomplicated course rate is 91%. Follow-up of 77% of operated patients showed satisfactory overall results in 81% of patients treated with Dacron prosthesis and in less than 50% after parietal suturing. Aseptic recurrence factors and late sepsis factors are also studied. Finally the efficiency of POE prosthetic repair is stressed and mandatory rules for the safe of Dacron Mesh are underlined.

[Sigmoid volvulus in children. About 6 cases (author's transl)].

About six of sigmoid volvulus m children, the authors underline the rarity of this etiology in large bowel obstruction. Two cases happened during neonate and four cases are associated with other pathologic diseases (2 neurologic ans 2 Hirschsprung diseases). Diagnosis is based on baryum enema and the best surgical management in emergency is resection and derivation with secondary anastomosis.
