We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have been reported in the literature; however, we describe herein superselective angiographic findings in more detail and demonstrate the arteriovenous shunt more clearly than the previous reports. In addition, a literature review was performed to discuss the association of a developmental venous anomaly with vascular lesions.

Intracranial arteriovenous malformation is rarely presented in newborns or infants. We describe an unusual case of congenital arteriovenous malformation of the brain with multiple sequestered grape-like venous sacs presented with congenital hydrocephalus. This 4-month-old girl born with a large head, presented with progressive hydrocephalus over a period of 4 months. The brain CT showed multiloculated cysts with a high-density mural nodule and thin cerebral mantle. The right lateral ventricle was collapsed by the cystic lesion, and the contralateral ventricle was markedly dilated, which was thought to be due to aqueductal obstruction by the conglomerated nidus of the arteriovenous malformation. Surgical removal of both hemispheric masses, including the overlying thin mantle. The lesion was pathologically confirmed as the arteriovenous malformation which was composed of markedly dilated veins and multiple sequestered aneurysmal sacs. The overlying cerebral tissue was dysplastic and partly infarcted. This case shows that intracerebral arteriovenous malformation is indeed a congenital anomaly and suggests that intrauterine vascular compromise can result in focal or wide maldevelopment of the brain.

Aneurysm of the vein of Galen is a very rare disease. The authors present a case of secondary aneurysm of the vein of Galen which was confirmed by characteristic clinical symptoms, brain CT and angiographic findings. The patient was a 14-year-old right handed girl with intermittent headache, nausea, vomiting, dysphasia and gait disturbance. Neurologic examination revealed dysarthria, nasal voice, blurring of both margins of optic discs, truncal ataxia and dysdiadochokinesia. Sensory function was normal but right hemiparesis was seen. Roentgenogram of the skull revealed diffuse thinning of the calvarium, widening of sella turcica and erosion of clinoid processes. Computed tomogram of the brain showed dilatation of all ventricles and round hyperdense mass behind the third ventricle in the midline. The lesion was enhanced markedly and homogeneously. Left and right internal carotid angiograms showed arteriovenousmal-formation with drainage to the aneurysm of the vein of Galen.

In this report, we descrbed a case of multiple brain abscesses associated with diffuse congenital pulmonary arteriovenous malformations (PAVM). Although the cases of brain abscesses associated with congenital PAVM are very rare, the brain abscess could be an initial clinical manifestation in asymptomatic PAVM as in the case presented in this report. PAVM may contribute to the development of a brain abscess by allowing easy bacterial access to systemic circulation through the right-to-left pulmonary vascular shunt, bypassing the filtering effect of the pulmonary capillaries. Hence, this association should be considered in cases with brain abscesses of undetermined etiologic factors.

We have had 37 patients with cerebral arteriovenous malformation and subarachnoid hemorrhage, who were admitted to the Department of Neurosurgery, Yonsei Medical Center from 1964 to 1976. All of the cerebral arteriovenous malformations were proved by cerebral angiography. Since the site of the lesions were considered to have a close relation to the neurologic deficit and the results of surgery, various analysis of clinical manifestations and of the cerebral angiographic findings were attempted. Out of 37 patients, surgery was performed in 28 and the results were analysed according to the various type of surgical procedure.

Arteriovenous malformation (AVM) of the brain is one of the important pathologic conditions which cause intracerebral or subarachnoid hemorrhage, epilepsy, or chronic cerebral ischemia. The spontaneous regression of cerebral AVM is reported to be very rare and more likely to occur when the AVM is small, is accompanied by hemorrhage, and has fewer arterial feeders. We report a case of right occipital AVM which at follow-up angiography performed four years later showed near-complete spontaneous regression.

Arteriovenous malformations are extremely rare conditions in that can result from abnormalities in the structure of blood vessels, which may be potentially fatal. A 30-year-old female patient visited our hospital with a complaint of swelling on the right maxillary posterior gingiva along with the large port-wine stain on right side of face. On clinical examination, the swelling was compressible and pulsatile. Radiographic examination revealed a lytic lesion of maxilla. Diagnostic angiography revealed a high-flow arteriovenous malformation of maxilla which was treated by selective transarterial embolization of maxillary artery using polyvinyl alcohol particles.

OBJECTIVETo introduce the technique of transarterial interventional embolization treating for arteriovenous malformations (AVM) in the face.

METHODSFrom April 1998, 17 patients have been treated with this method. Seldinger's maneuver was used in this series. Of them, 11 cases received only interventional embolization; 6 cases received both interventional embolization and surgical resection.

RESULTSThe interventional embolization was effective in all the 17 cases, which was confirmed by immediate angiography. Their clinical symptoms were gradually relieved. Interventional embolization obviously decreased hemorrhage during surgical resection.

CONCLUSIONSInterventional embolization provides a new way for the treatment of AVM. Preoperative embolization can lower the surgical risk as it obviously decreases hemorrhage during the surgical procedure.

This report concerns a 4-month-old infant with progressive prominent and redness of his left eye since birth. This report concerns a 4-month-old infant with progressive prominent redness of his left eye since birth. Angiography revealed a congenital pial arteriovenous fistula between the temporal branch of the left posterior cerebral artery and left cavernous sinus through the sphenoparietal sinus, a condition not reported in the literature. The fistula was successfully occluded with two micro-coils by vertebrobasilar approach.
