There was analyzed the risk of surgical intervention in patients, suffering abdominal aorta aneurism, using the risk indices POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity) and GAS (Glasgow Aneurysm Score). The theoretically obtained indices were compared with the real indices and the availability of the indices for the practice were determined. The investigation was done in 122 consequent patients, suffering infrarenal abdominal aorta aneurism, to whom the abdominal aorta prosthesis was performed in 2005-2007 yrs. Lethality was 9.8% and complications rate--51.6%. The ROC curve analysis (the interrelationship curve of false-positive and true-positive results) and the analysis of square under the curve were performed for the indices availability analysis. The indices did not reveal high specificity for the lethality prognostication. |
