Full textAbdominal aortic aneurysms occur in 5-9% of the population over the age of 65, and rupture of these aneurysms cause every year at least 15,000 deaths. Although most AAAs are small and asymptomatic, their diameter typically increases over time and about 60% eventually require surgical repair. To date, no therapy can slow or stop the growth of small aneurysms. The aneurysmal wall is characterized by chronic inflammation and tissue remodeling involving synthesis and destruction that leads to the loss of elastin. All these elements are present in the elastase model of aneurysm in mice. While many data have been accumulated on the involvement of metalloproteinases in the degradation of the extracellular matrix, the role of serine proteases has received much less interest. Using this model in mice cathepsin S and cathepsin C knockout, we have shown that their presence was essential for aneurysmal development. We also showed that it was possible to block the model using E64, an inhibitor of cathepsins. Taken together these data suggest that cathepsins play a role in the initiation of the inflammatory reaction and that cathepsins are a potential way of research for the development of medication which could slow down the AAAs growth. In order to block by pharmacological means the model, we developed the possibility to infuse doxycyline directly on the aneurysm. These studies showed that it was possible to block the model with an infusion of local doxycycline without blood levels of doxycycline. This experimental work opens the way for the development of drug-eluting stent graft, i.e. a stent graft able to infuse an active product which can stabilize the wall of the aneurysm

Full textCardiovascular diseases are the first cause of mortality around the industrialized world with a continuous increase in their incidence along with the expansion of the major risk factors such as aging, obesity and diabetes. In abdominal aortic aneurysm (AAA), the presence of inflammatory infiltrates, and particularly monocytes/macrophages, has underscored the contribution and importance of immuno-inflammatory responses in aneurysmal degeneration. It is one of the most common diseases of the abdominal aorta and presents a major health problem. The importance of macrophages has recently been highlighted by a number of evidence, which are the main population observed within the site of aneurysm, are believed to derive from circulating monocytes although no direct evidence has been provided to date. Recent evidence has shown that their accumulation is particularly enhanced in the early onset of AAA in mice, and that the inhibition of CCR2/ MCP1 signaling as well as the early depletion of circulating monocytes, are protective. Hence, it seems crucial to understand the mechanisms of monocyte recruitment in the initiation and progression of AAA. In this PhD project with a particular interest in abdominal aortic aneurysm, we were particularly interested in understanding the trafficking behavior of monocyte subsets in AAA and their role in disease pathogenesis. Using a mouse model of aneurysm induction in ApoE-/- mice, we showed that Ang II triggered the mobilization of Ly-6Chigh, and to a lesser extent Ly-6Clow monocytes, from the spleen and their consequent recruitment in the aorta. Spleen removal or B lymphocyte deficiency in Apoe-/- mice similarly impaired early monocyte mobilization in response to Ang II and protected against AAA development, independently of blood pressure. Reconstitution of Apoe-/- Rag-/- mice with total splenocytes but not with B-Cell depleted splenocytes restored monocyte mobilization in response to Ang II and enhanced susceptibility to AAA. Taken together, this study provides novel mechanistic insights on the early events involved in AngII-induced AAA formation. It highlights the role of the splenic monocyte reservoir in this process and identifies an intriguing role for B lymphocytes in mediating AngII-induced early and transient mobilization of splenic monocytes. Nevertheless, further understanding of the molecular mechanisms that underlie such interactions is likely to lead to the identification of effective therapeutic targets

Full textEndovascular aneurysm repair (EVAR) and transcatheter aortic valve implantation (TAVI) are endovascular interventions where preoperative CT image analysis is a prerequisite for planning and navigation guidance. In the case of EVAR procedures, the focus is specifically on the challenging issue of aortic segmentation in non-contrast-enhanced CT (NCCT) imaging, which remains unresolved. For TAVI procedures, attention is directed toward detecting anatomical landmarks to predict the risk of complications and select the bioprosthesis. To address these challenges, we propose automatic methods based on deep learning (DL). Firstly, a fully-supervised model based on 2D-3D features fusion is proposed for vascular segmentation in NCCTs. Subsequently, a weakly-supervised framework based on Gaussian pseudo labels is considered to reduce and facilitate manual annotation during the training phase. Finally, hybrid weakly- and fully-supervised methods are proposed to extend segmentation to more complex vascular structures beyond the abdominal aorta. When it comes to aortic valve in cardiac CT scans, a two-stage fully-supervised DL method is proposed for landmarks detection. The results contribute to enhancing preoperative imaging and the patient's digital model for computer-assisted endovascular interventions

Full textThe goal of this study is to determine complementary criterions to existing morphological criterions justifying the surgical operation to treat abdominal aortic aneurysms (A. A. A. ), that are not reliable. The realization of this goal goes through the characterization of fluids dynamics inside A. A. A. . Long et al. (2004) showed that beyond a diameter of 5 cm, the A. A. A. Wall became compliant again. To study influence of this compliance, first of all, we set up an experimental study, in which we compared two models of A. A. A. , one rigid and one soft. Afterwards, we realized numerical simulations in order to get to parietal haemodynamic parameters. These two studies showed the influence of the wall compliance, as well as the influence of haemodynamic conditions on dynamics inside A. A. A. . The compliance of the aneurysmal wall might become another criterion to justify surgical intervention
