Active angiogenesis in an extensive arteriovenous vascular malformation: a possible therapeutic target?
V ascular malformations result from the aberrant development of vascular elements during embryogenesis and fetal maturation. Despite apparent endothelial quiescence, some vascular malformations can expand rapidly during adolescence or pregnancy, after a surgical procedure, or in response to trauma. The pathogenesis of vascular malformations is not well clarified, but their formation and progres...
متن کاملArteriovenous malformations and other vascular malformation syndromes.
Vascular malformations are a disruption of the normal vascular pattern in which it is expected that a capillary network of microscopic vessels lies interposed between high-pressure arteries that deliver blood and thin-walled veins that collect low-pressure blood for return to the heart. In the case of arteriovenous malformations, arteries or arterioles connect directly to the venous collection ...
متن کاملGlioblastoma Mimicking an Arteriovenous Malformation
Abnormal cerebral vasculature can be a manifestation of a vascular malformation or a neoplastic process. We report the case of a patient with angiography-negative subarachnoid hemorrhage (SAH) who re-presented 3 years later with a large intraparenchymal hemorrhage. Although imaging following the intraparenchymal hemorrhage was suggestive of arteriovenous malformation, the patient was ultimately...
متن کاملSpontaneous hemorrhage in an intraorbital arteriovenous malformation.
OBJECTIVE To report the clinical findings and management of spontaneous hemorrhage in an unsuspected intraorbital arteriovenous malformation. DESIGN Interventional case report. METHODS Review of clinical findings, radiologic studies, and treatment of the patient. RESULTS A 75-year-old woman sought treatment for the rapid onset of severe proptosis. Orbital exploration of a "mass" imaged on...
متن کاملBalloon-assisted Onyx Embolization of an Extensive Mandibular Gingival Arteriovenous Malformation: a case report
This is a rare case of mandibular arteriovenous gingival malformations with episodes of spontaneous bleeding and referred to our department for emergent interventional therapy. Onyx was chose as embolic agent due to its specific physical properties and infuse under balloon-assisted technique for good penetration of embolic particles into the nidus and feeders. We present this case and share the...
