    Objective/BackgroundPersistent type II endoleak (EL II) with sac enlargement after endovascular repair of abdominal aortic aneurysm requires treatment to prevent rupture. Embolization is not always effective. Conversion to open repair with stent graft (SG) explantation is a high risk option. The aim of this study was to evaluate the feasibility and immediate results of an alternative technique combining obliterative endoaneurysmorrhaphy (OEA) with SG preservation.MethodsThe open surgical technique combined sacotomy, ligation of all patent back-bleeding vessels and SG preservation. The aneurysmal shell was tightly closed over the SG to protect it from the intestines. An intra-aortic occlusion balloon was used when clamping was required.ResultsTwelve patients were treated with the OEA technique at Amiens University Hospital. All 12 procedures were successful. Four patients had previously undergone unsuccessful transarterial or translumbar embolization. Aortic clamping was performed in four cases. No SG migration or graft dislocation was observed. Follow up computed tomography scan at a median of 12 months showed shrinkage of the aneurysm sac with stable diameters and no recurrence of EL II in all cases.ConclusionThe OEA technique is an alternative option for the treatment of progressive EL II, which can be particularly useful after failure of embolization

    PURPOSE The main purpose of the study was to report the estimated incidence, cumulative rate, risk factors and outcomes of submacular haemorrhage (SMH) with loss of vision in neovascular age-related macular degeneration (nAMD) receiving intravitreal injections (IVT) of vascular endothelial growth factor (VEGF) inhibitor in routine clinical practice. METHODS Retrospective analysis of treatment-naïve eyes receiving IVTs of VEGF inhibitors (ranibizumab, aflibercept or bevacizumab) for nAMD from 1 January 2010 to 31 December 2020 that were tracked the Fight Retinal Blindness! registry. Estimated incidence, cumulative rate and hazard ratios (HR) of SMH with loss of vision during treatment were measured using the Poisson regression, Kaplan-Meier survival curves and Cox proportional hazard models. RESULTS We identified 7642 eyes (6425 patients) with a total of 135 095 IVT over a 10-year period. One hundred five eyes developed SMH with loss of vision with a rate of 1 per 1283 injections (0.08% 95% confidence interval [95% CI] [0.06; 0.09]). The estimated incidence [95% CI] was 4.6 [3.8; 5.7] SMH with loss of vision per year per 1000 treated patients during the study. The cumulative [95% CI] rate of SMH per patient did not increase significantly with each successive injection (p = 0.947). SMH cases had a mean VA drop of around 6 lines at diagnosis, which then improved moderately to a 4-line loss at 1 year. CONCLUSIONS Submacular haemorrhage (SMH) with loss of vision is an uncommon complication that can occur at any time in eyes treated for nAMD in routine clinical practice, with only limited recovery of vision 1 year later

    Les maladies cardiovasculaires sont la première cause de morbidité et de mortalité dans les pays développés. Les AVC sont sources d'handicap et ont donc un impact économique majeur. Au cours des dernières décennies, des avancées importantes en terme de traitement mais aussi de prévention primaire et secondaire ont été réalisées face à ce problème de santé publique. Une meilleure connaissance de la physiopathologie de cette pathologie et de ses mécanismes génétiques sous-jacents permettra d'en améliorer le diagnostic et le traitement. Dans ce travail nous avons cherché à étudier l'intérêt physiopathologique des miARN au cours de l'évolution de la plaque carotidienne. Nous avons réalisé une revue approfondie de la littérature sur l'implication des miARN dans l'ACV d'origine carotidienne. Puis, nous avons réalisé une étude pilote dont le but était de comparer l'expression de plusieurs miARN d'intérêt entre des plaques carotidiennes humaines symptomatiques et asymptomatiques. Enfin, nous avons étudié l'expression de ces miARN dans le sérum de ces patients et établit des corrélations avec les données cliniques et paracliniques et notamment les facteurs de risque d'athéroclérose. La surexpression significative de miR-100, miR-125a, miR-127, miR-133a, miR-145 et miR-22 a été mise en évidence au sein des plaques carotidiennes symptomatiques par rapport aux asymptomatiques. L'expression de miR-125a était corrélée au taux sanguin de LDL cholestérol chez les patients symptomatiques. L'expression sérique de miR-127 et miR-145 était significativement diminuée chez les patients symptomatiques, d'où leur potentielle utilisation comme biomarqueur. La revue de la littérature a montré que d'autres miARN (tels que le miR-124, miR-210 et miR-223) ayant fait l'objet d'études dans des modèles cellulaires, animaux et chez l’homme sont également de bons candidats comme biomarqueurs dans l'AVC. De futures études idéalement multicentriques sur de larges échantillons permettront de mieux définir les applications de ces petits ARN en tant que biomarqueurs non invasifs et outils thérapeutiques en pratique dans la prise en charge de l'AVC et des pathologies cardiovasculaires.Cardiovascular diseases are the leading cause of morbidity and mortality in developed countries. Stroke is associated with a marked disability burden and has a major economic impact ; this is especially true for carotid artery stroke. Major advances in primary and secondary prevention aver the last few decades have helped to tackle this public health problem. Better knowledge of the pathophysiolgy of stroke and its underlying genetic mechanisms is needed to improve diagnosis and therapy. In this work we focused on stroke from carotid artery origin and studied pathophysiological interest of miRNA during carotid plaque progression. We made a detailed review about the involvement of miRNA in carotid-related stroke. Then we performed a pilot study with the aim to compare the expression of several miRNA, allegedly involved in plaque growth and intability, between symptomatic and asymptomatic plaques. We finally compared circulating miRNA expression between symptomatic and asymptomatic patients and we analyzed the association of several stroke risk factors with the expression level of miRNA. miR-100, miR-125a, miR-127, miR-133a, miR-145 and miR-221 were significantly overexpressed in symptomatic carotid plaques compared to asymptomatic plaques. miR-125a expression was significantly inversely correlated with the circulating level of low-density lipoprotein cholesterol in the symptomatic group. The expression of circulating miR-127 and miR-145 was significantly lower in symptomatic patients compared to asymptomatic, suggesting their potential role as biomarkers. Studies on cellular models, animal models and humans have shown that others miRNAs such as miR-124, miR-210 and mir-223, could be good candidates as biomarkers of stroke. Further multicenter studies based on large numbers of patients are needed to confirm the miRNAs

    Introduction. Le but de cette étude était d évaluer la faisabilité et les résultats de l anévrysmorraphie oblitérante avec conservation de l endoprothèse dans le traitement des endofuites de type 2 ou indéterminées associées à un accroissement du sac anévrysmal. Matériel et méthodes. Dans cette étude multicentrique rétrospective, 24 patients d âge moyen 77 ans ont été inclus. Une embolisation première a été réalisée chez 10 (42%) patients sans succès. Dans 21% des cas la fuite n était pas visible à l angioscanner et dans 17% des cas son origine restait indéterminée. Le délai moyen avant anévrysmorraphie était de 35 mois pour un diamètre du sac anévrysmal moyen de 79 mm, soit une augmentation de 18 mm par rapport au diamètre initial. Un clampage cœliaque a été réalisé chez 5 patients et un ballon d endoclampage mis en place chez 7 patients. Une endofuite de type 2 seule était retrouvée chez 18 patients et une endotension chez 2 patients. Une endofuite de type 2 était associée à un type 1 distal dans 1 cas, à un type 3 dans 2 cas et à un type 4 dans 1 cas. Résultats. Le taux de succès technique était de 100% avec un taux de mortalité opératoire nul. Le taux de mortalité à 30 jours était de 4%. La durée moyenne de séjour était de 13 jours. Trois patients ont eu des ré-interventions pour complications septiques (1 précoce et 2 tardives). Le suivi moyen était de 11,5 mois. Il n a été constaté aucune endofuite persistante ni aucune anomalie sur les endoprothèses au cours du suivi. Conclusion. L anévrysmorraphie oblitérante avec conservation in situ de l endoprothèse est une technique fiable avec de bons résultats précoces et à moyen terme, moins invasive qu un remplacement aortique et plus efficace que l embolisation.AMIENS-BU Santé (800212102) / SudocSudocFranceF

    microRNAs in the pathophysiology of CKD-MBD: Biomarkers and innovative drugs

    No full text
    International audiencemicroRNAs comprise a novel class of endogenous small non-coding RNAs that have been shown to be implicated in both vascular damage and bone pathophysiology. Chronic kidney disease-mineral bone disorder (CKD-MBD) is characterized by vessel and bone damage secondary to progressive loss of kidney function. In this review, we will describe how several microRNAs have been implicated, in recent years, in cellular and animal models of CKD-MBD, and have been very recently shown to be deregulated in patients with CKD. Particular emphasis has been placed on the endothelial-specific miR-126, a potential biomarker of endothelial dysfunction, and miR-155 and miR-223, which play a role in both vascular smooth muscle cells and osteoclasts, with an impact on the vascular calcification and osteoporosis process. Finally, as these microRNAs may constitute useful targets to prevent or treat complications of CKD-MBD, we will discuss their potential as innovative drugs, describe how they could be delivered in a timely and specific way to vessels and bone by using the most recent techniques such as nanotechnology, viral vectors or CRISPR gene targeting

    Aortic valve calcification in the era of non-coding RNAs: The revolution to come in aortic stenosis management?

    No full text
    International audienceAortic valve stenosis remains the most frequent structural heart disease, especially in the elderly. During the last decade, we noticed an important consideration and a huge number of publications related to the medical and surgical treatment of this disease. However, the molecular aspect of this degenerative issue has also been more widely studied recently. As evidenced in oncologic but also cardiac research fields, the emergence of microRNAs in the molecular screening and follow-up makes them potential biomarkers in the future, for the diagnosis, follow-up and treatment of aortic stenosis. Herein, we present a review on the implication of microRNAs in the aortic valve disease management. After listing and describing the main miRNAs of interest in the field, we provide an outline to develop miRNAs as innovative biomarkers and innovative therapeutic strategies, and describe a groundbreaking pre-clinical study using inhibitors of miR-34a in a pre-clinical model of aortic valve stenosis
