Venous pressures were measured within the vein of Galen aneurysm/straight sinus complex in 15 patients with Galenic arteriovenous fistulae and vein of Galen aneurysms. Pressures exceeded normal (less than 5 cm of H2O) in each instance, ranging between 9 and 55 cm of H2O. Measured values exceeding 20 cm of H2O were associated with an increased occurrence of brain calcification. Mean venous press...

rteriovenous malformation of the vein of Galen, also known as vein of Galen aneurysm, is a distinct intracranial anomaly characterized by a midline, deeply located, high-flow lesion with an extremely complex vascular architecture. Although they represent fewer than 1% of all cerebral arteriovenous malformations seen in children and adults, almost all cases diagnosed in the fetus and neonate inv...

azygos vein aneurysm is a rare cause of a posterior or paratracheal mediastinal mass. trauma or conditions causing elevated flow or pressure in the azygos system, such as cardiac failure or cirrhosis of the liver are secondary causes of aneurysm of the azygos vein. we report a case of asymptomatic saccular aneurysm of the azygos vein in a 45-year-old man with blunt minor chest trauma. the azygos...

We report an unusual case of a ruptured aneurysm from an infraoptic anterior cerebral artery in an 11-year-old child. To our knowledge, this is the second such case treated with Guglielmi detachable coils in the pediatric population that has been described in the literature, excluding that of a vein of Galen aneurysm that resulted in remarkable recovery. We conclude that the endovascular techni...

We present the prenatal diagnosis of a vein of Galen aneurysm in a 34-week fetus. The aneurysm was 8 x 3.5 x 3 cm in dimension, and located posterior to the third ventricle. Color flow examination revealed a turbulent flow in the lesion. There was significant cardiomegaly. Prenatal ultra-fast magnetic resonance imaging was used to view the malformation in three dimensions. Although the pregnanc...

A 6-month-old girl , while being evaluated by her family physician for otitis media, was found to have a head circumference of 47 cm (99th percentile), with a tense and full anterior fontanelle. Past medical history was unremarkable, with normal developmental milestones. A noncontrast CT scan showed enlarged lateral and third ventricles and a homogeneous, high-attenuation mass in the region of ...

We applied computational fluid dynamic (CFD) analysis on the numerical grid of a 3D rotational digital subtraction angiogram obtained in a 22-year-old male patient, with an accidentally discovered vein of Galen malformation associated with single feeder aneurysm, to understand the flow pattern through the two aneurysms and improve our general understanding of hemodynamic characteristics of this...

Arteriovenous malformations of the vein of Galen are rare , usually presenting with cardiac failure in infancy or with hydrocephalus and raised intracranial pressure in older children [1]. Computed tomographic (CT) and angiographic features are well known [2 , 3]. Magnetic resonance imaging (MRI), however, is a new imaging modality, and experience with aneurysms of the vein of Galen is not yet ...
