By Yasargil classification it is divided into four types; type I shows small cisternal fistula between the vein of Galen
and the pericallosal arteries or posterior cerebral artery, type II showing multiple fistulae between the vein of Galen
and the thalamoperforating vessels, type III is a mixed variety of type I and II and type IV: parenchymal arteriovenous malformation (AVM) with drainage into the vein of Galen
Diagnosis and management of vein of Galen
He was transferred to Wellington Hospital and a magnetic resonance imaging (MRI) and further specialist investigation confirmed the primary diagnosis of Vein of Galen
5), (6) There is also a distinction between the VGM and the Vein of Galen
aneurysmal dilation (VGAD) which are AVMs localised in the subpial space, which drain into a tributary of the vein of Galen
, resulting in overload and dilatation.
That is how they were able to diagnose the Vein of Galen
condition so early.
Vein of Galen
malformation is a rare and usually fatal condition where an abnormal communication between the arteries and veins in the brain causes stress to the heart.
Although patients with high flow shunts through Vein of Galen
abnormalities may present with severe cardiovascular abnormalities secondary to the shunt, our patient's presentation did not suggest significant cardiovascular impairment and pressure on the trachea from an abnormal cardiovascular structure such as an enlarged left atrium seemed unlikely.
The vascular lesions included 4 vein of Galen
malformations, 2 cerebral aneurysms, 14 cerebral AVMs, 2 spinal AVMs, 1 posterior fossa dural AVF and 1 indirect acquired CCF.
INTRODUCTION: The vein of Galen
is located under the cerebral hemispheres and drains the anterior and central regions of the brain into the sinuses of the posterior cerebral fossa.
Vein of Galen
aneurysmal malformation (VOGM) is an arterio-venous fistula involving aneurysmal dilatation of the median prosencephalic vein of Markowski.
In London they diagnosed vein of Galen
, which meant blood was being pumped from his arteries to his veins.
