International workshop on Cerebral Venous Thrombosis (ISCVT), 20 years later, what next ?

Publié dans Saison 2017-2018

Introduction

Cerebral venous thrombosis (CVT), is a rare and long neglected variety varety of stroke which can be due to a multitude of causes such as head trauma, surgery, pregnancy and delivery and a host of medical conditions. Once thought to be frequently lethal, CVT has nowadays a good prognosis , provided that it is diagnosed and treated very early.

20 years ago, J Ferro, from Portugal lounched the first International Study on Cerebral Venous Thrombosis (ISCVT), which he chaired together with 3 of us coming from Mexico (FB), Nederland (JS) and France (MGB). The purpose of the present meeting is to summarize the progresses made in the last 20 years, to review the ongoing trials, and to discuss new potential diagnostic tools and therapeutic measures in order to further improve the acute and long term prognosis of patients suffering CVT.

Genetics by Pankaj Sharma

CVT is an understudied subtype of stroke. As is known to affect young (mainly female) patients its aetiological cause has been mainly linked to hormonal relationships. Notwithstanding this gender difference, the presence of this condition in a younger population opens up the tantalising possibility that there is a likely genetic susceptibility to CVT. Several investigators across the world have attempted to dissect such an aetiological basis but the relatively rarity of this condition means that no single investigator has had the capability to identify its genetic basis in a robust and reliable fashion. This talk will summarise the know data on CVT genetics and also present information about the ongoing international study to establish the largest genetic DNA bank in CVT in order to enable us to better understand the genetic basis of this important condition.

Isolated intracranial HT and sinus pathology by Jérôme Mawet

Almost 20 years ago, attention was drawn on the fact that cerebral venous thrombosis may present as an isolated intracranial hypertension, mimicking idiopathic isolated hypertension (IIH).

Today, radiological evidence of cerebral venous sinus stenosis in almost all patients with IIH and improvement of IIH after venous sinus stenting in case series suggest that the spectrum of cerebral venous disease is larger and not only relies on occlusion, but that cerebral venous stenosis may also be highly clinically relevant. This presentation will present the present data on venous disorders and intracranial hypertension and discuss the actual treatment recommendations.

CVT and woman hormonal life by Isabelle Crassard and Geneviève Plu-Bureau

Cerebral venous thrombosis is three times more common among women than men. This sex ratio could be partly explained by specific female factors like oral contraceptives and to lesser extent pregnancy and post-partum. Combined hormonal contraceptives (CHC) increased the risk of CVT. The increase in thrombotic risk is the highest the first year of CHC use and 3rd generation (desogestrel or gestodene) or drospirenone or cyproterone acetate combined with ethinyl-estradiol CHC use are associated with an increased venous thrombotic risk as compared to 2nd generation (levonorgestrel combined with ethinyl-estradiol) CHC use. Moreover, the increased risk of venous thrombosis from CHC use may be synergic to that of biological thrombophilia. Despite a wide variety of clinical presentations, early diagnosis of CVT, mostly based on MRI/MRA, is essential but often difficult particularly during post-partum because of the numerous causes of headache that may occur after delivery. There are not specific clinical or radiological pattern of CVT during pregnancy and post-partum. The prognosis of CVT is however better in women with gender specific risk factors than in other causes of CVT, with a complete recovery in 80% of patients. Future pregnancy is possible, but contraception with estro-progestogens is definitely contra-indicated. Progestin-only contraceptive is an alternative for women with contraindication of estrogen use. By contrast with COC, low doses of both oral progestin contraceptives and intra-uterine levonorgestrel could be safe with respect to venous thrombotic risk.

CVT and RCVS: is there a link? by Anne Ducros

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe headaches, often of the thunderclap type, and multifocal constriction of cerebral arteries, that resolve spontaneously in 1 to 3 months. More than half the cases of RCVS occur in special circumstances such as exposure to vasoactive substances or postpartum. A few patients with RCVS occurring in the setting of a CVT have been described, underscoring the fact that a patient with severe headaches might have two distinct underlying vascular disorders. Diagnosis relied on careful clinical analyses of the headache features and serial cerebral imaging.

Several hypotheses can be raised to explain the association of CVT and RCVS. It is difficult to imagine that a CVT could by itself trigger cerebral arterial constriction. Both conditions may share the same cause, e.g. postpartum or female hormonal treatments. Since RCVS has also been reported in the setting of abnormal intracranial pressure, intracranial hypertension due to CVT might trigger a RCVS. Conversely, post lumbar puncture syndrome might also be involved.

MGB 600Marie-Germaine Bousser

Marie-Germaine BOUSSER is emeritus Professor of Neurology at Paris Diderot University and former head of the Neurology department of Lariboisière Hospital in Paris. She is a headache and stroke specialist and was one of the Presidents of the International Headache Society and of the French headache society. She was one of the founders of the European Stroke Conference and she was the founder and first President of the French Stroke Society.

Cerebral venous thrombosis (CVT) has long been one of her favorite topics. She published in 1985 a series of 38 patients suffering from CVT in which she was one of the first to recommend the use of heparin treatment. In 1992, together with R. Ross Russell, she published a book on CVT. In the last 20 years, MG BOUSSER and her co-worker Isabelle CRASSARD gathered a cohort of over 500 patients with CVT about which they have written many articles on various aspects of this disorder.

Luca Antonio Ramenghi is the Medical Director of Neonatal Intensive Care Unit at Gaslini Children’s Hospital. His main scientific interest has been since the begining of his career the diagnosis of brain lesions acquired during the perinatal period, in term and preterm babies (intraventricular haemorrhage, cerebellar haemorrhage, perinatal arterial stroke and perinatal axphyxia). The first pubblication were based on the use of transfontanellar ultrasound and in the following years on brain MRI of neonates.
