Intravenous DSA of three different mice (a, b, c) which developed pseudoaneurysm after vessel perforation (black arrows). Pseudoaneurysms arose from the proximal intracranial ICA (n = 2; a, b) and the proximal ACA (n = 1; c). Both ICA aneurysms showed a faster growth rate than of the ACA over several days with sudden death of both animals probably due to aneurysm rupture.
