“…Since the microsurgical technique with the aid of the operating microscope makes it possible to remove these lesions radically, this angiographic investigation is indispensable. This is not in agreement with the statement of Henderson and Gomez (1967) that the rare finding of a removable angioma or aneurysm in the posterior fossa (or occipital lobe) did not justify the added risk of routine complete serial four vessel angiography. Our series of cases definitely demonstrates the fact that a considerable number of supratentorial AVMs have their blood supplies also from the vertebral-basilar arterial system and that knowledge of this blood supply is necessary for the planning of the surgical procedure.…”

From a series of 325 cases of cerebral arteriovenous malformations, seven patients are reported presenting a change in size of the malformation in the course of several years. The enlargement of the malformation is documented by four vessel cerebral angiography, and haemodynamic and histopathological characteristics are discussed. Serial four vessel cerebral angiography is strongly indicated for accurate diagnosis, and radical excision of these malformations with the microtechnical method is advocated.

“…In total, we identified only 48 cases with delayed angiography at least 1 year after diagnosis. Of these cases, 28 (58%) AVMs enlarged, 16 (33%) remained the same and 4 (8%) became smaller [1,2,3, 6, 8,34,35,36,37,38,39,40,41]. This suggests that enlargement in size may be part of the normal pathophysiology of an AVM.…”

Background: Arteriovenous malformations (AVMs) are commonly thought to be congenital malformations; however, patients usually present in adolescence or adulthood. This study was carried out to better understand the development of AVMs between birth and presentation. Methods: A retrospective review was performed of the medical records of all patients under 25 presenting to a single institution with an AVM or spontaneous intracerebral hemorrhage from 2000 to 2007. Results: Out of a total of 34 cases, 3 children were identified with delayed de novo appearance of an AVM after an intracerebral hemorrhage and normal initial angiography. The clinical and angiographic features are presented for these 3 patients and for an additional patient with AVM recurrence after complete surgical excision. Conclusions: In the light of these cases and a review of the literature, we suggest a hypothesis that AVMs develop postnatally, undergoing a period of growth in childhood or early adulthood, and that they may become symptomatic from the time of their earliest development. The trigger to growth may be shear stress stimulating growth factor expression by endothelial cells lining an arteriovenous fistula. Alternative stimuli, such as venous hypertension, cannot be ruled out.
