The association of cerebral aneurysms, infundibula, and intracranial arteriovenous malformations.
Intracranial arteriovenous malformations (AVMs) are congenital communications between the cerebral arteries and veins without an intervening capillary network. The association of the malformations with other vascular lesions such as intracranial aneurysms has previously been reported. We have reviewed 132 consecutive patients with intracranial AVMs evaluated angiographically at New England Medical Center. In addition to the expected high incidence of saccular aneurysms, a high incidence of arterial infundibula was found. A review of the association between the AVMs, aneurysms and infundibula, and possible etiologic factors in the relationship forms the subject of this report.
