Importance of cerebral pan-angiography for detection of multiple aneurysms in patients with aneurysmal subarachnoid haemorrhage.
In the Danish Aneurysm Study 948 patients had a ruptured intracranial aneurysm (RA) revealed by cerebral angiography. Unilateral carotid angiography (UCA) with or without vertebral angiography (VA) demonstrated the RA in 206 patients, and 16 (7.8%) unruptured aneurysms (UA) were disclosed by UCA and 1 UA by VA. In 740 patients with at least bilateral carotid angiography (BCA) 164 UA (22.2%) were disclosed by BCA and 10 by VA. I.e. the number of UA demonstrated in patients with RA is not only doubled by BCA compared to ipsilateral UCA, but tripled demonstrating that an additional UA is more likely situated on the opposite side of the RA. Pan-angiography (or at least BCA) is therefore recommended in patients with RA.
