[Risk factors in aorto-iliac surgery (author's transl)].

The authors report a statistical analysis of 163 operations of aorto-iliac vascular surgery. A detailed study of their 14 deaths showed the various causes of mortality (immediate post-operative thrombosis, acute renal failure, digestive complications, septic cardiac, pulmonary, hemorrhagic and cerebro-vascular accidents). This analysis, compared with the findings in all the operated patients showed the main factors of risk in this type of surgery (age over 70 years immediate and late reoperations, heart lesions, renal, pulmonary and late lesions, the risk of sepsis). The indicate the means of prevention of such accidents and the therapeutic attitude when they occur. They conclude that the contra-indications are relative, but should be observed in order to lower the risk of this surgery below 5 p. cent mortality rate.
