Brain arteriovenous malformations

Neurology, 2020
Brain arteriovenous malformations (AVMs) are anomalous direct shunts between cerebral arteries and veins that convalesce into a vascular nidus. The treatment strategies for AVMs are challenging and variable.

Complete regression of intracranial arteriovenous malformations

Surgical Neurology, 2002
Spontaneous and complete regression of intracranial arteriovenous malformations (AVMs) is a rare occurrence, with only 59 angiographically proven cases reported in the English literature. We present three new cases and perform a literature review to determine possible mechanisms underlying this unusual phenomenon.Three patients with angiographically ...

Intracranial Arteriovenous Malformation Surgery

2017
Intracranial arteriovenous malformations (AVMs) are vascular abnormalities consisting of direct connections between arteries and veins, bypassing capillaries. Resection of AVMs is a technically challenging neurosurgical procedure, particularly when they are located near eloquent areas with risk of severe neurological impairment.

Surgical Treatment of Intracranial Arteriovenous Malformation

Neurological Research, 1982
The surgical indication and techniques of intracranial arteriovenous malformations are discussed, on the basis of 203 experiences with AVMs. A special key point in our surgical techniques is described as follows. The feeding arteries of the AVM--or the main artery at the base of the brain, which is the original source of the feeding artery--are ...

Endovascular Treatment of Intracranial Arteriovenous Malformation

Neurosurgery Clinics of North America, 2009
Arteriovenous malformations (AVMs) of the brain are vascular lesions in which an abnormal tangle or nidus of vessels permits pathologic shunting of blood flow from the arterial to the venous tree without an intervening capillary bed. With brain imaging techniques, an increasing number of AVMs are detected before they hemorrhage, leading to new ...

Association of intracranial aneurysm and arteriovenous malformation

Medical Journal of Australia, 1983
In a series of 252 patients (47 with arteriovenous malformation, 205 with aneurysms), two patients had a coexisting intracranial aneurysm and an arteriovenous malformation. In one patient, the aneurysm was proximal to the main feeding arteries of the arteriovenous malformation.

Association of an intracranial arteriovenous malformation and a meningioma

Neuroradiology, 1998
A case of a simultaneously discovered arteriovenous malformation (AVM) and a meningioma is presented. A review of the literature revealed only four similar cases, but there have been 30 reports of other intracranial tumors in association with AVM. The possible mechanisms of this rare association are discussed.

Growing intracranial arteriovenous malformation in a newborn

Child's Nervous System, 1986
A case is reported of a growing arteriovenous malformation in a newborn, premature baby. The reason for early operative intervention is emphasized, based on histological investigation of the malformation. The literature is reviewed.

The change is size of intracranial arteriovenous malformations

Journal of the Neurological Sciences, 1973
Abstract Twenty-one patients with an intracranial AVM were subjected to 2 separate serial carotid angiograms. The median time between examinations was 44 months. The volumes of the malformations were calculated using an ellipsoid volume approximation. The median volume in the first angiogram was 5.8 cm 3 and in the second angiogram 7.1 cm 3 . With a
