      PopulationFigure 1 demonstrates how the sample population was divided between procedure and admission type. It can be seen that in this study the majority of cases underwent a repair of their aneurysm; in only 9% (79/884) was a decision made not to operate or the patient died before receiving surgery. Of the repairs performed, 93% (752/805) were done by an open surgical procedure and more commonly as an elective procedure.  |
