[Results of surgery in 144 cases for aneurysms of the infra-renal abdominal aorta in patients over 75 years of age].

114 patients aged over 75 underwent surgery for aneurysm of the infra-renal abdominal aorta in the University Teaching Hospitals in Nantes and Angers between 1979 and 1988. A retrospective study of these patients was performed to evaluate the immediate and long-term results. The mean age of the patients was 79 (+/- 4) years, the oldest being 94. 70% were men. Half of the patients underwent emergency or semi-emergency surgery (52 cases). Cardiovascular factors (in particular coronary insufficiency in 17% of cases) were the most common risk factors. In all cases grafting after laying open the aneurysm was performed, with an aorto-aortic graft in 32% of patients, an aorto-iliac graft in 37% or an aorto-bifemoral graft in 27% of patients. Combined intestinal revascularisation was performed in 10% of case either involving the inferior mesenteric artery or at least one internal iliac artery; renal revascularisation was performed in 3.5% of cases. 75% of patients underwent simple grafting. The mean duration of hospitalisation was 14 days (+/- 6), including a mean period of 7 days in ICU. 36 patients (31%) died in the first post-operative month. The mortality rate in patients who underwent emergency surgery for a complication of the aneurysm (essentially rupture) was 61% versus 6' for elective surgery. 96% of the patients who survived the first post-operative month were independent at the end of the study or at the time of their death.(ABSTRACT TRUNCATED AT 250 WORDS)

[Electroencephalographic changes in patients with cardiopathies, subsequently operated under extracorporeal circulation. Significance and outcome. Evaluation of 679 cases].

This study analysed the pre-operative electroencephalographic recordings of 679 patients with heart disease, later undergoing surgery under extra-corporeal circulation. The type and the severity of the abnormalities are listed for each heart disease. These results are compared to those already published in the literature on this subject and are discussed in terms of a number of possible aetiological factors: the age of the patients, data provided by the pre-operative cardio-pulmonary assessment. This analysis does not enable us to demonstrate, with any statistical significance, the aetiological factor(s) of these electroencephalographic alterations. Finally, comparison of the pre-, intra- and postoperative EEG in the same patients enables us to evaluate the prognostic value of these electrical abnormalities.
