BACKGROUND The pathogenesis of infantile hemangiomas is not yet understood. Growth factors and hormonal and mechanical influences have been thought to affect the focal abnormal growth of endothelial cells in these lesions. However, these influences may represent secondary responses to an underlying primary molecular event leading to the development of hemangiomas. OBSERVATIONS We report the r...

BACKGROUND Vascular malformations and hemangiomas, which are endothelial lesions of childhood, may result in considerable morbidity because they can cause discomfort and functional impairment and have a negative affect on the patient's appearance. Although vascular malformations may initially appear very similar to hemangiomas, they have distinct clinical courses. Infantile hemangiomas progress...

The field of extracranial vascular anomalies is considered as special focus of pediatric otolaryngology and it has shown a rapid development during the last years. The reason for this interest is finally also due to the global acceptance of the classification introduced by the ISSVA (International Society for the Study of Vascular Anomalies). Hemangiomas are the most frequently observed vascula...

A retrospective study of 502 patients treated with tunable flashlamp pulsed dye laser for superficial vascular malformations (433), ulcerated hemangiomas (65) and postinvolutional redness (4) is presented. Patients were treated in the period from June 1997 to March 2006, with follow-up ranging from six months to four years. The age of the patients ranged from three months to 80 years. Correlati...

PURPOSE To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations. METHODS Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography. RESULTS Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. ...

Introduction: Hepatic hemangiomas (HH) are the most common benign tumors of liver and consist vascular malformations or hamartomas congenital origin that increase due to ectasia. The declared giant hepatic (GHH) embody from 10 cm (most commonly) 20 more

Post-partum haemorrhage is a major determinant of maternal mortality. Traditionally, cases of post-partum haemorrhage caused by arterial injuries were managed by caesarean hysterectomies or bilateral internal iliac artery ligations. The diagnosis of aneurysms or arteriovenous malformations of uterine artery are often missed. Uterine curettage, caesarean section or vaginal delivery can result in...

PURPOSE Our goal was to describe the prevalence and types of cerebral vascular malformations (CVMs) seen with MR imaging in patients with hereditary hemorrhagic telangiectasia (HHT). METHODS We reviewed retrospectively the brain MR images of 184 consecutive patients with HHT. Catheter angiography was performed in 17 patients with CVMs detected on MR images. RESULTS MR imaging revealed 63 CV...

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...
