The indications, technique, and results of embolization of arteriovenous malformations with liquid adhesive agents delivered through the anterior choroidal artery are reported. Arteriovenous malformations of the temporal lobe were found in four patients with intracerebral bleeding and two with intractable epilepsy. In five of the six, the dominant arterial feeder was the anterior choroidal arte...

The association of intracranial hypertension and arteriovenous malformations is described in two patients. Both patients had the typical clinical features of pseudotumour cerebri and were found to have intracranial arteriovenous malformations on arteriography. The mechanism of raised intracranial pressure in patients with arteriovenous malformations is discussed.

OBJECTIVE To evaluate the occurrence of pulmonary arteriovenous malformations after a Fontan operation in the left isomerism and absent inferior vena cava. METHODS We retrospectively reviewed 19 patients with the left isomerism and absent inferior vena cava who underwent Fontan operations at our institution. We divided the patients into two groups: bilateral superior vena cava (group A, n=9),...

The roles of the Notch pathway proteins in normal adult vascular physiology and the pathogenesis of brain arteriovenous malformations are not well-understood. Notch 1 and 4 have been detected in human and mutant mice vascular malformations respectively. Although mutations in the human Notch 3 gene caused a genetic form of vascular stroke and dementia, its role in arteriovenous malformations dev...

Pulmonary arteriovenous malformations are abnormal direct communications between pulmonary arteries and pulmonary veins. Transcatheter embolotherapy is the preferred treatment method because of its less invasive nature. There are several methods for the treatment of pulmonary arteriovenous malformations, such as detachable occlusion balloon and coil embolization. The Amplatzer Vascular Plug is ...

PURPOSE Follow-up of vascular changes in a patient with congenital retinocephalofacial vascular malformation syndrome. METHODS MRI and cerebral angiography. RESULTS In a 36-year-old man, magnetic resonance imaging of the skull and cerebral angiography revealed left intracranial arteriovenous malformations. Follow-up observation of 27 years revealed no essential change of retinal and cerebra...

A role for the Notch signalling pathway in the formation of arteriovenous malformations during development has been suggested. However, whether Notch signalling is involved in brain arteriovenous malformations in humans remains unclear. Here, we performed immunohistochemistry on surgically resected brain arteriovenous malformations and found that, compared with control brain vascular tissue, No...

Hereditary hemorrhagic telangiectasia (HHT; Osler-Weber-Rendu syndrome) is an uncommon disease characterized by abnormal telangiectasias and arteriovenous malformations that cause recurrent bleeding. Here, we present the case of a patient with HHT, who had a history of pulmonary and hepatic arteriovenous malformations and endocarditis of a prosthetic aortic valve that was caused by methicillin-...

abstract background: the gamma knife radiosurgery (gkr) is an established management option for cerebral ar-teriovenous malformations (avms). therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. methods: radiosurgery was performed between february 2003 and april 2010 at kamraniye day clinic, teh-ran, iran, usi...
