Vascular malformations of the central nervous system.

HYPERVITAMINOSIS A-INDUCED CENTRAL NERVOUS SYSTEM DEFECTS

In this investigation the effects of excess vitamin A administration during the early embryonic period were studied. Intramuscular injection of a single dose of 15000,20000 or 25000 IU/kg vitamin A to pregnant Balb/c strain mice on either day 7,8,9 or 10 of gestation (vaginal plug= day 0 of gestation) produced major malformations in the central nervous system (CNS) including exencephaly, h...

Intraventricular Cerebrovascular Pathologies of Hydrocephalus and Managements

Cavernous malformations (CM), also called cavernous angiomas and cavernomas, are lowflow vascular malformations that constitute 5-13% of all central nervous system vascular malformations (Moriarity et al., 1999; Raychaudhuri et al., 2005). On the other hand, IVC are rare pathological entities, constituting 2,5-10.8% of cerebral CM (Kivelev et al., 2010). The first report of an IVC was published...

Skin and Soft Tissue Injuries in Congenital Vascular Malformations

Concepts and controversies in the management of cerebral developmental venous anomalies.

d evelopmental venous anomaly is a widely used synonym for venous angioma or cerebral venous malformation [1]. DVAs are the most frequently encountered cerebral vascular malformation and are frequently reported as incidental findings in computed tomography and magnetic resonance imaging studies. Radiological and autopsy series have demonstrated that DVAs occur in 2.5 to 3% of the general popula...

Associated Risk Factors and Prevalence of Congenital Malformations in Ardabil, Iran

Introduction: Congenital anomalies are the most common cause of disability in developed and developing countries. Costs of hospitalization and treatment of congenital anomalies pose a significant burden to families and societies. The objective of the present study was to determine the associated risk factors and prevalence of congenital malformations in Ardabil, Iran. Methods: This cross-secti...
