Biology of vascular malformations of the brain.

BACKGROUND AND PURPOSE This review discusses recent research on the genetic, molecular, cellular, and developmental mechanisms underlying the etiology of vascular malformations of the brain (VMBs), including cerebral cavernous malformation, sporadic brain arteriovenous malformation, and the arteriovenous malformations of hereditary hemorrhagic telangiectasia. Summary of Review- The identificati...

MR and CT of occult vascular malformations of the brain.

The need for improved specificity in the diagnosis of "occult" vascular malformations led to the use of MR in suspected cases in order to determine MR's potential for improved diagnostic accuracy. Six patients with six lesions histologically diagnosed as vascular malformation after partial (1) or complete (5) microsurgical excision were studied by CT, MR, and selective magnification subtraction...

Sirolimus: A Rapid Treatment for Coagulopathy Because of Vascular Malformations

vascular malformations in the maxillofacial region

congenital vascular lesions occur most often in children. parents of these children take them to maxillofacial surgeons directly or during the treatment of other complications such as infection or jaw bone disorders. various terms now used are unable to describe the pathogenesis and mechanism of the effect of vascular lesions on growth and development of facial bone.  term of hemangioma is used...

Vascular malformations

1. Venous malformations: congenital venous anomalies pathologically characterised by anomalous veins (thickened and hyalinised walls) separated by normal brain. These anatomically abnormal veins drain normal brain tissue. It is thought that they result from intrauterine ischemic event occurring during the formation of medullary veins resulting in collateral venous drainage. This is the most com...

Management of Vascular Malformations

BACKGROUND Even though vascular malformations are well categorized, further details are relatively unknown. Of treated patients regarding the frequency, demographic distributions, and other related factors by multivariate regression analyses in proportion to total vascular malformations, methods of treatment and how to manage them have not been elucidated thoroughly. METHODS From January 2006...
