In the management of a patient with a ruptured aneurysm, the immediate goal is to prevent a second bleed as re-bleeding has a 60-80% risk of death and severe disability. The risk of a re-bleed is approximately 1.5% per day, reaching a cumulative risk of 20% at the end of the first 2 weeks, and 50-60% at the end of 6 months.
The best treatment option is often individualised, depending on the site, shape and location of the aneurysm. The patient’s age and clinical condition are also factors to consider.
