Value of neurological and angiographic signs as indicators of the ruptured aneurysm in patients with multiple intracranial aneurysms

Summary

The purpose of the study was to assess the reliability of certain neurological and angiographic signs for the identification of the site of the rupture in patients with multiple intracranial aneurysm.

The series presented consisted of 101 patients with verified SAH and angiographically demonstrated multiple aneurysms. The ruptured aneurysm was verified by operation or at autopsy.

The commonest and most useful sign was the difference in size of the aneurysm; in 95 cases the larger or largest aneurysm was the ruptured one. Utilizing angiographie signs alone, identification of the responsible lesion was possible in 97 cases (96 per cent). By combining the neurological and angiographie signs, the ruptured aneurysm was correctly identified in 98 cases (97 per cent). Neurological signs were less frequently present than angiographic signs, and in addition they are useful only in cases with the aneurysms on opposite sides, except for oculomotor palsy, which always points to the ruptured posterior communicating aneurysm.
