Intracranial arteriovenous malformations can be further complicated by the development of aneurysms, which themselves carry the risk of rupture and hemorrhage. New endovascular techniques allow for more treatment options for these lesions in the setting of arteriovenous malformations. Here we present the case of a patient who developed an aneurysm in the setting of an arteriovenous malformation...

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...

Behavioral effects have been found to result from the prenatal administration of substances known to be teratogenic to the CNS. These effects occur at dose levels lower than those producing gross malformations and when the agent is administered at times other than that optimal for CNS relevant technique for detecting adverse consequences of prenatal exposure to drugs and chemicals. Behavioral t...

Brain arteriovenous malformations cause intracranial hemorrhage. Molecular characterization of lesional tissue implicates angiogenic (vascular endothelial growth factor, ANG-2, matrix metalloproteinase-9) and inflammatory (cytokines and chemokines) pathways, but the pathogenesis remain obscure and medical therapy is lacking. Macrophage and neutrophil invasion has also been observed in the absen...

PURPOSE To determine whether there is a physiologic explanation for the predisposition of patients with certain angiographic characteristics to symptoms of hemorrhage and steal. METHODS Superselective transcatheter feeding arterial pressure and mean arterial pressure measurements were obtained before embolotherapy in 32 patients with cerebral arteriovenous malformations. Pressures were correl...

Cardiovascular Dimensions in Patients With Intracranial Arteriovenous Malformation • The hemodynamics of 29 adult subjects with a congenital intracranial arteriovenous malformation were studied by radiocardiography. The cardiac index, heart rate, stroke index, systemic arterial pulse pressure and radiographical heart volume did not differ significantly from the normal. However, the total blood ...

PURPOSE This study aimed to estimate the prevalence and incidence of cerebrovascular disease (CVD) and stroke in Korean male adolescents. MATERIALS AND METHODS The authors reviewed all medical certificates, medical records, and radiologic images from the examinations of Korean military conscription from January 2008 to May 2011. RESULTS Of the 101,156 examinees, 40 had CVD and stroke during...

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterised by vascular malformations in multiple organ systems, resulting in mucocutaneous telangiectases and arteriovenous malformations predominantly in the lungs (pulmonary arteriovenous malformation; PAVM), brain (cerebral arteriovenous malformation; CAVM), and liver (hepatic arteriovenous malformation; HAVM)....

OBJECTIVE To investigate the incidence and characteristics of patients with structural central nervous system (CNS) lesions and cerebrospinal fluid oligoclonal IgG bands. DESIGN A retrospective study. METHOD The medical records of patients with cerebrospinal fluid oligoclonal IgG bands were evaluated for the presence of structural CNS lesions, their location and cause, and for clinical char...

Capillary malformation (CM), or "port-wine stain," is a common cutaneous vascular anomaly that initially appears as a red macular stain that darkens over years. CM also occurs in several combined vascular anomalies that exhibit hypertrophy, such as Sturge-Weber syndrome, Klippel-Trenaunay syndrome, and Parkes Weber syndrome. Occasional familial segregation of CM suggests that there is genetic s...
