background: radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (avm) may be used as markers for specific vascular targeting agents. in this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (pecam-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

BACKGROUND AND PURPOSE Arteriovenous malformations are an important etiology of hemorrhagic stroke. However, current imaging modalities and risk do not provide insights into individual AVM hemodynamics and its role in pathophysiology. The aims of this study are to determine whether intracranial 4D flow MR imaging can provide insights into arteriovenous malformation hemodynamics independent of t...

Pulmonary arteriovenous malformation (AVM) is not routinely appreciated during the standard echocardiogram to assess for structural abnormalities or pulmonary hypertension. The distal pulmonary AVM is suspected only if an injection of agitated saline is performed and late entry of particles is appreciated in the left heart structures. A large or complex pulmonary AVM can result in significant r...

BACKGROUND The treatment of giant deep arteriovenous malformations (AVMs) remains challenging. CASE DESCRIPTION We report a case of giant deep AVM diagnosed in a 9-year-old girl, for whom the AVM rupture occurred 9 years later. At the age of 9, the girl developed mild left hemiparesis. Magnetic resonance imaging revealed a giant deep AVM. The patient underwent one course of stereotactic radio...

Arteriovenous malformation (AVM) is the most common cause of spontaneous intraparenchymal hemorrhage in children, excluding hemorrhages of prematurity and early infancy. Because most children diagnosed with an AVM undergo initial treatment emergently, the natural history of AVMs in the pediatric population is not well understood. Most pediatric AVMs do not come to clinical attention unless they...

Avian vacuolar myelinopathy (AVM) is a neurologic disease primarily affecting bald eagles (Haliaeetus leucocephalus) and American coots (Fulica americana). The disease was first characterized in bald eagles in Arkansas in 1994 and then in American coots in 1996. To date, AVM has been confirmed in six additional avian species. Attempts to identify the etiology of AVM have been unsuccessful to da...

This report describes a rare case of a patient with arteriovenous malformation in the parotid region that received endovascular treatment. A 44-year-old female who presented with cardiac murmur in the left neck on close examination was referred to our hospital. Physical findings included left jugular vein distention, swelling of the left neck, and vascular murmur on auscultation. Cervical magne...

Uterine arteriovenous malformation (AVM) is a rare entity in gynecology with fewer than 100 cases reported in the literature. Due to abnormal connection between arteries and veins without an intervening capillary system, recurrent and profuse vaginal bleeding is the most common symptom which can be potentially life-threatening. Uterine AVM can be either congenital or acquired. Acquired AVM is r...

Avian vacuolar myelinopathy (AVM) is a disease of unknown etiology, which has been diagnosed in a variety of birds from surface water reservoirs in the southeastern United States. Pathology suggests a natural or anthropogenic compound may be the cause of this disease. With the goal of identifying the toxicant that causes AVM, we qualitatively analyzed sediments and American coot (Fulica america...
