Apport pronostique de l'IRM (1TESLA) de diffusion et de perfusion a la phase hyperaigue des accidents vasculaires cérebraux ischémiques by Anne-Christine Januel( Book )

1 edition published in 2001 in French and held by 2 WorldCat member libraries worldwide

Objectif : Definir chez des patients victimes d'un AVD ischemique a un stade hyperaigu (<6 heures) des valeurs pronostiques grace aux sequences d'IRM de diffusion, de perfusion et d'angio MR. Materiels et methodes : Une etude prospective chez 12 patients porteurs d'un AVC ischemique a compris un bilan TDM et IRM (T2, flair, diffusion et perfusion, angioMR), dans les 6 premieres heures puis a J+4 et une IRM a 4 mois. Resultats : Nous avons etabli des correlations entre les volumes lesionnels definis par les differentes sequences d'IRM et les scores cliniques initiaux et finaux. Les sequences de diffusion et de perfusion a J0 sont tres bien correlees au volume infarci defini sur la sequence T2 de l'IRM a 4 mois, mais egalement au score clinique final. Les patients presentant une occlusion proximale sur l'angioMR, ont tous une evolution clinique plus defavorable. Conclusion : A un stade hyperaigu de l'AVC ischemique, les sequences de diffusion, de perfusion et d'angioMR paraissent predictives de la taille finale de l'infarctus et du devenir clinique a long terme. Les differents coefficients de diffusion et de perfusion etudies (ADC, TTP, VSC) devraient permettre d'etablir des donnees parametriques dans l'ischemie cerebrale et l'identification de plusieurs groupes relevant de therapeutiques differentes (techniques de desobstruction ou de repermeabilisation vasculaire et traitement neuroprotecteurs)
Apport de l'imagerie multimodale avancée au bloc de neuroradiologie interventionnelle by Jildaz Caroff( )

Since the very beginning of Interventional Neuroradiology (INR), the two pillars of this young specialty born in the 1960-70 have been both technological innovation and imaging. Thanks to numerous evolutions, we now can navigate our catheters anywhere in the brain. And all the available devices allow us to open an obstructed artery, occlude an hemorrhagic lesion or reconstruct a pathological vessel. The resolution of digital subtraction angiography has gradually improved over the years but up until recently we did not benefit from diverse options to plan and evaluate our treatments. The first part of this work consisted in demonstrating the clinical potential of a widely available but underused modality, the Cone Beam Computed Tomography. It allows a very good visualization of devices presenting a low radiodensity. In a second part, we exposed through multiple preclinical models, the potential impact of intravascular imaging with optical coherence tomography. Only used in the cardiology field, it could become an in vivo microscope for the analysis of neurovascular diseases and their treatment. Finally, after the description of morphological imaging modalities, we demonstrated the interest of functional imaging for the treatment planning of the cerebrovascular diseases managed by INR. We will illustrate this imaging progression through two very different approaches to treat intracranial aneurysms ; one endosaccular (WEB device) the other parietal (Flow diverter stents). In total, the importance of imaging is continuously growing in our field, because of the diversification of INR imaging. There is no doubt that in few years from now the multiplicity of these data will be provided through advanced reality systems similarly with pilots helmet mounted displays. In the future, it is possible that treatments will even be performed through imaging when magnetic resonance system will allow the remote navigation of catheters up to their pathological target

Remnants and Recurrences After the Use of the WEB Intrasaccular Device in Large-Neck Bifurcation Aneurysms( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract : BACKGROUND: Flow disruption with the WEB technique has been developed to treat large-neck bifurcation aneurysms. OBJECTIVE: To report our anatomic angiographic results at first (3-6 months) and second (18 ± 3 months) angiographic follow-up in a series of 15 patients. METHODS: Fifteen patients (15 aneurysms) were consecutively treated in our center by 2 operators for a large-neck bifurcation aneurysm between March 2012 and February 2014. Results were evaluated by assessing WEB cage position at the aneurysm neck on angiography and high-resolution contrast-enhanced flat-panel detector computed tomography, contrast medium stagnation within the WEB and aneurysm on intraprocedural angiography, and 1-day time-of-flight magnetic resonance angiography. All aneurysms were followed up by angiography. Results at follow-up were graded as complete occlusion, neck remnant, or residual aneurysm. The 2 operators compared postprocedural and follow-up images and classified them as better, same, or worse. Subtracted images were compared in different projections to assess any WEB device compression or shape changes. RESULTS: A worsening was observed between the postprocedural and first follow-up angiography in 10 of 14 (71.5%) and in 4 of 7 (57.2%) between the first and second control angiography. Compression of the WEB cage was observed at first follow-up in 8 of 14 (57.2%) and in an additional 3 of 7 cases (42.8%) at second control. Last angiography showed complete occlusion in 1 of 14 (7.2%), neck remnant in 8 of 14 (57.2%), and residual aneurysm in 5 of 14 (35.7%) cases. CONCLUSION: This article draws attention to the risk of WEB compression and aneurysm recanalization. Future prospective studies should evaluate delayed WEB shape changes with different types of WEB devices (dual layer, single layer, single layer spherical).
