Association of aneurysm and arteriovenous malformation on the posterior inferior cerebellar artery. Report of three further cases and review of the literature.
As far as we know, only 20 patients with association of aneurysm and arteriovenous malformation (AVM) on the posterior inferior cerebellar artery (PICA) have been reported so far. Further three personal cases are presented here and the pertinent literature is reviewed, the coexistence of aneurysm(s) and AVM on the PICA district increases the risk of intracranial bleeding compared with patients harbouring this association in the cerebral hemispheres. The direct approach of both lesions (excision of the AVM and clipping of the aneurysm) in one-stage operation is the treatment of choice.
