The authors evaluate resection therapy on aneurysms of abdominal aorta in patients of high age (mean 85 years) at the Clinic of Surgery in Plzen. In the period of 1998-March 2003 the authors performed 13 elective resections on aneurysms of abdominal aorta in patients of high age with zero mortality and 21 acute resections with 38% mortality. In the given period of time, 178 resections of aneurysms of abdominal aorta were made in patients younger than 78 years, 57 being acute interventions. Mortality of elective interventions was 2.9%, in acute interventions being 28%. The present groups indicate that mortality of resection therapy sharply increased in relation to circulation instability of the patients in cases of ruptured aneurysm, but nor in relation to age of the patients.
