background traditional digital subtraction angiography (dsa) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (avm) and dural arteriovenous fistulas (davf). objectives the aim of this study was to analyze different less invasive magnetic resonance angiography (mra) images, time-resolved mra (tr-mra) and three-dimensional ti...

The complete or partial spontaneous disappearance of a cerebral arteriovenous malformation is rare. Spontaneous thrombosis in large arteriovenous malformations has been reported in only two cases. We report the case of a large arteriovenous malformation in a 17-year-old man, that thrombosed spontaneously after minor surgical manipulation and review the literature and some possible mechanisms fo...

Seven neonates with arteriovenous malformation of the vein of Galen are described. Six presented with cyanotic heart failure. Two cases had antenatal cerebral infarction, five periventricular leukomalacia, and three recent haemorrhagic infarction. Cerebral damage due to the malformation suggests that surgical correction of the arteriovenous malformation offers little to neonates, though after t...

central nervous system infection is a rare complication of endovascular procedures. we report a 21-year-old woman presented with headache, nausea, vomiting, and right-sided hemiparesis 4 months after endovascular embolization of cerebral arteriovenous malformation. investigations led to the diagnosis of multiple brain abscesses. this is the sixth case report of brain abscess following endovascu...

A 63-year-old male presented with a cerebral arteriovenous malformation in the dominant motor area which subsequently disappeared spontaneously. He had suffered from epileptic attacks in his right extremities for 2 years before he first presented aged 53 years. He was treated with anticonvulsants and was followed up. Bleeding from the cerebral arteriovenous malformation occurred when he was 61 ...

PURPOSE To characterize cerebral hemodynamics in patients immediately before microsurgical resection of moderate to large arteriovenous malformations during isoflurane anesthesia. METHODS In angiographically defined arteriovenous malformation feeding and nonfeeding arteries, transcranial Doppler studies were performed in 25 surgeries on 22 patients. The mean blood flow velocity and pulsatilit...

Spontaneous regression of cerebral arteriovenous malformation is rare and less than hundred cases have been reported in literature. The authors report a case 64 year/male who was diagnosed with which found to undergo spontaneous on repeat imaging. phenomenon.

The incidence of aneurysmal subarachnoid hemorrhage is about 10-11 cases per 100,000 inhabitants. The true incidence of multiple aneurysms is not known, however, according to previous studies it may vary between 20% and 30%. The association of arteriovenous malformation and cerebral aneurysm is well documented and varies between 20% and 30%. A case is described of a 47-year-old female presentin...

Seventeen patients with an intracranial arteriovenous malformation were studied with positron emission tomography. Cerebral blood flow, cerebral blood volume, oxygen extraction fraction, and glucose and oxygen metabolism were evaluated in both hemispheres, excluding the area of the malformation itself. Patients were divided into three groups according to the size of their malformation, and resu...
