The impact of rebleeding on the life time probabilities of different outcomes in patients with ruptured intracranial aneurysms. A theoretical evaluation.
In order to strengthen patient-information a theoretical evaluation of the impact of rebleeding on the life time probabilities of different outcomes in patients with an aneurysmal subarachnoid haemorrhage (SAH) has been made using a life table method. The calculations were performed for SAH-presenting ages from 20 to 70 years assuming a rate of rebleeding of 50% in the first 6 months after the initial bleeding with a mortality rate of 70%, and the following years an annual rate of rebleeding of 3%, and with a mortality rate of 60%. A survey of the life time probabilities of the 4 different outcomes after an aneurysmal SAH shows the great life time reducing effect of rebleedings in all SAH-presenting ages.
