Rerupture of intracranial aneurysms during angiography.
We analyzed 70 patients (64 from the literature and 6 of our own cases) who had suffered from rerupture of their aneurysms during angiography. When these cases are compared with those who had suffered rupture of their aneurysms only once and a rerupture, which did not coincide with angiography, they were clinically distinguished by a higher Hunt-Hess grade, a higher rate of IC aneurysms, less operability, far miserable outcome and concentration of aneurysmal rerupture within three hours after the initial subarachnoid haemorrhage. It is suggested waiting at least 3 hours after SAH before performing angiography and to use digital subtraction angiography in order to prevent aneurysmal rerupture during angiography.
