Partial interruption of inferior vena cava (I.C.V.) forms an integral part of treatment of thromboembolic disease. The most frequently used filter worldwide is currently that of Greenfield, but although its effectiveness and permeability are remarkable it can be the subject of transfixions, sliding movements and migrations. A new model of the authors' own conception is presented which eliminates these faults. The "2612" filter is based on the same concepts, but has added to it 6 lateral flanges soldered to the base of the arms, these applying pressure to the I.V.C. and ensuring its perfect positioning, and 12 hooks (6 turned downwards and 6 upwards) ensuring perfect stability. Results of a multicentre trial in 35 patients, after insertion of the "2612" filter and follow-up assessment after 3 months (28 cases) by cavography and in some patients by a scan, showed permeability of 93% and total efficacy. No side effects were reported. This filter appears to represent true progress in the means of interrupting I.V.C., and further studies are contemplated.

[Malignant transformation of endometriosis: a hypothesis on its histogenesis].

Carcinomatous degeneration of the endometrium is rarely seen. The authors consider the pathogenesis of this disorder based on two authentic cases. On the basis of their previous studies of the endometrium, the authors suggest that endometriotic centers are simply "dystrophies" developing from subcoelomic mesenchymal cells which although quiescent are still capable of proliferation and differentiation. "Dystrophies" are insensitive to hormonal incitation and this would explain the rarity of carcinomatous degeneration of the endometrium.

[Thoracic complications caused by catheterization of the superior vena cava system].

The authors report on 8 observations of respiratory complications, following catheterization of the superior caval system. They mention its clinical features, the seriousness of its development and the diagnostic procedure. The symptomatic treatment is based on the evacuation of the extravasation and the withdrawal of the catheter. Sometimes there has to be recourse to surgery. Finally, the authors emphasize the need for prevention of such typically iatrogenous complications.

[Bone and vascular injuries of the popliteal fossa. Apropos of 21 cases].

The authors report twenty-one cases of bony and vascular trauma of the popliteal fossa. The first step in the appropriate treatment of these lesions is to be aware of the associations of the two types of lesion, independent of the degree of bony damage; an isolated dislocation may be associated with a sub-adventitial rupture of the popliteal artery. Surgical treatment consists of bony fixation followed by vascular repair, which requires autologous popliteo-popliteal or femoro-popliteal venous by-pass grafts in 90 per cent of cases. This repair should concern both the artery and the vein, as the immediate prognosis depends on the complete repair of both vessels. The immediate results essentially depend on the nature of the traumatic aetiology: gunshot wounds, or motor vehicle accidents, and on the quality of the vascular repair. The long term prognosis depends on the quality of the orthopaedic treatment. In every case, the classical reputation of the severity of such associated lesions is fully justified.

[Ruptured aneurysms of the aorta. Analysis of a series of 75 cases].

Rupture of an abdominal aorta aneurysm was treated in 75 patients between 1969 and 1984. Global mortality was 70%, and factors influencing mortality, and its causes, are analyzed in this series. The presence and course of hemorrhagic shock is the essential prognostic factor, as well as the type of rupture. Mortality as a function of the groups varied between 27 and 90%. Causes of early mortality were directly related to collapse and its severity, other types of fatal complication being related to the patients general condition. Prognosis is improved by early diagnosis and rapidity of operative treatment. This series represents, in fact, only 36% of the total aneurysms operated upon during the same period, and a preventive surgical attitude is the only means of improving overall prognosis.
