[Unusual procedures in the cure of aneurisms of the subrenal aorta (author's transl)].

From 1959 to 1977, out of 419 aneurisms of the subrenal aorta operated on, 84 were by unusual procedures: --25 restoratory endo-aneurismorraphies with thrombo-endarterectomy were carried out for small aneurisms in young subjects; --4 were enveloped in dacron (in particular for a risk of distal acute post-operative thrombosis); --in 55 cases, these were high risk surgical subjects where conventional treatment by removal of the aneurism and graft appeared to have a bad prognosis: 43 were treated by axillo-femoral by pass with ligature of the aorta just above the aneurism either for acute arterial obstruction with sensory and motor ischemia, or for embolism or for subjacent obstruction; 12 large advanced aneurisms with fissures of tears were treated by axillo-bifemoral by pass and exclusion. Depending on the results obtained, are deduced the operative indications for these procedures.
