Malformations of the Fetal Dural Sinuses

Abstract: RÉSUMÉ:Malformations de sinus crâniens chez le foetus. Résumé : Contexte : Le terme « malformation de sinus crânien » est utilisé pour décrire des malformations vasculaires congénitales caractérisées par une dilatation massive d'un ou de plusieurs sinus crâniens. Ces dilatations sont en général associées à des shunts artério-veineux. Bien que ces malformations puissent être détectées avant la naissance, leur histoire naturelle et leur anatomie précoces sont mal connues. Méthodes : Nous avons révisé les autopsi… Show more

“…3,5,6 When they are midline in location, they have been reported to have a worse prognosis. 1 Midline DSMs with giant venous pouches are thought to result from uncontrolled dilation of the posterior sinuses, including the torcula and posterior SSS, with associated multiple low-flow AV shunts.…”

“…3,5 In this paper we report on a combined percutaneous and endovascular embolization approach. This approach was used in the management of 2 of these malformations with atypical angioarchitectural features, which were not amenable to conservative management or endovascular embolization alone.…”

“…Thrombosis of the fetal intracranial dural sinuses is a rare entity, with less than 20 cases reported in the literature with fetal MRI findings [1][2][3][4][5][6][7][8][9]. Thrombosis of the dural venous sinuses postnatally in infants and children can be caused by a host of abnormalities producing prothrombotic states such as underlying systemic conditions (sepsis, acute lymphoblastic leukemia, dehydration, homocystinuria), vascular trauma, vascular malformations and genetic factors with deficiencies of physiological anticoagulants such as antithrombin, protein C or protein S [10][11][12].…”

“…The consensus in the literature as to the cause of this type of fetal dural sinus thrombosis at the torcular Herophili is a type of congenital dural sinus malformation (DSM) with low-flow arteriovenous shunts [3][4][5][6]16]. DSMs are classified into midline with giant a b The midline dural sinus malformation with giant pouches is typified by abnormal development and growth of the posterior sinuses (transverse sinuses, torcular Herophili and posterior SSS) associated with multiple slow-flow arteriovenous shunting within the wall of the malformed sinus [4].…”
