The femoral tripod remains technically crucial in vascular surgery, as well for an elective revascularization as for an extensive approach to the arterial tree. The management of septic complications and healing disorders in this area is really challenging. Obturator bypass (OB) represents an alternative sometimes employed in this context, but few recent series were recently published. The objectives of this work were thus to evaluate the results of OB in terms of patency, morbi-mortality, healing evolution and absence of reinfection.

Nutcracker syndrome (NCS) describes the symptomatic compression of the left renal vein between the aorta and superior mesenteric artery. Whereas asymptomatic compression is a common radiological finding, patients with NCS can report a range of symptoms. There are no specific diagnostic criteria and interventions include a range of open surgical and endovascular procedures. Therefore, we wished to develop an international consensus document covering aspects of diagnosis, management, and follow-up for patients with NCS.

Thanks to its well proved long-term patency rates, native radiocephalic arteriovenous fistula remains the most commonly used vascular access type. Many articles had approached the criteria leading to a mature fistula. The aims of this work are to evaluate variables that may affect the maturation of distal fistulas and to determine if wrist fistulas have less risk of maturation failure than the snuff-box fistulas.

A biomechanical approach to the rupture risk of an abdominal aortic aneurysm could be a solution to ensure a personalized estimate of this risk. It is still difficult to know in what conditions, the assumptions made by biomechanics, are valid. The objective of this work was to determine the individual biomechanical rupture threshold and to assess the correlation between their rupture sites and the locations of their maximum stress comparing two computed tomography scan (CT) before and at time of rupture.

Long-term outcomes of accessory renal artery (ARA) coverage after endovascular aneurysm repair (EVAR) are unknown. We analyzed the impact of ARA coverage on renal function long-term.

The aging of the population leads us to treat older patients, in particular presenting with acute limb ischemia (ALI). However, there has been little evaluation of this pathology in the nonagenarians. The objectives of this work are thus to evaluate the 1-month and 1-year mortality of the nonagenarians treated for ALI, which made possible to determine the 1-year survival and to highlight the factors influencing the mortality.

The main objective of this study was to identify the changes that have occurred in the treatment of abdominal aortic aneurysms (AAA) in France over a period of 10 years.

Patients suffering from chronic mesenteric ischemia are at risk of malnutrition due to the fear of food and weight loss. However, the impact of malnutrition on the morbidity and mortality at the time of surgery is not studied extensively, just as its prevalence. The main objective of this study was to evaluate the influence of malnutrition on the survival of the patients operated for chronic mesenteric ischemia. The secondary objectives were to evaluate the prevalence of malnutrition in this population and to evaluate the early complications after surgery according to the nutritional condition of the patients.

Despite current progress, the prognosis of critical limb ischemia (CLI) remains poor. The ageing of the population, the increasing prevalence of diabetes mellitus, and the stability of tobacco use will increase the prevalence of CLI. CLI patients have risk factors for malnutrition, and the impact of malnutrition on morbidity and mortality has been demonstrated in the general population. However, we have little information on the consequences of undernutrition in the CLI population. The aim of this study is to assess the impact of malnutrition on the early outcomes in CLI patients.

Pancreaticoduodenal artery aneurysms (PDAAs) are rare, but rupture can occur at any time regardless of the size. We describe here the case of 53-year-old woman who presented with a ruptured PDAA associated with compression of the celiac trunk by the median arcuate ligament. We first performed revascularization of the celiac trunk without intervening on the PDAA because of surgically hostile conditions. We observed complete regression of the PDAA, probably due to the dramatic decrease in inflow to the PDAA, thanks to the revascularization procedure. This prompted us to cancel the secondary endovascular embolization. The patient remained asymptomatic at 3 months.

The aim of this study is to evaluate radiation exposure, endovascular theatre equipment, and practices in France during iliac angioplasty.

The renal safety of suprarenal (SR) fixation stent grafts has not been demonstrated yet. The principal objective of this study was to analyze the effect of the type of fixation of stent grafts on the renal function at 1 year, by calculating the estimated glomerular filtration rate (eGFR). The secondary objective was the evaluation of the morphological repercussion of the implants at the renal level by computed tomography.

The prevalence of obesity is increasing, and its impact on the outcome of open and endovascular abdominal aortic aneurysm (AAA) repair remains unclear, particularly in the European population. We herein assessed the impact of obesity on the postoperative course for both techniques.

The complications of EVAR require compliance to a close follow-up imaging. The purpose of this study was to determine whether home location predicted a poor compliance to imaging follow-up after EVAR.

Randomized controlled trials that have established recommendations for carotid surgery have excluded patients >79 years of age, and in our day to day practice, patients in this age group are becoming more common. We sought to analyze the outcomes of carotid endarterectomy (CEA) in octogenarians, determine the risk factors of morbidity and mortality, and evaluate the midterm survey of these patients.

To assess our current practice concerning the indications and the immediate and midterm results of femorofemoral bypass.

Millions of teeth are saved each year by root canal therapy. Although current treatment modalities offer high levels of success for many conditions, an ideal form of therapy might consist of regenerative approaches in which diseased or necrotic pulp tissues are removed and replaced with healthy pulp tissue to revitalize teeth. Melanocortin peptides (α-MSH) possess anti-inflammatory properties in many acute and chronic inflammatory models. Our recent studies have shown that α-MSH covalently coupled to poly-l-glutamic acid (PGA-α-MSH) retains anti-inflammatory properties on rat monocytes. This study aimed to define the effects of PGA-α-MSH on dental pulp fibroblasts. Lipopolysaccharide (LPS)-stimulated fibroblasts incubated with PGA-α-MSH showed an early time-dependent inhibition of TNF-α, a late induction of IL-10, and no effect on IL-8 secretion. However, in the absence of LPS, PGA-α-MSH induced IL-8 secretion and proliferation of pulp fibroblasts, whereas free α-MSH inhibited this proliferation. Thus, PGA-α-MSH has potential effects in promoting human pulp fibroblast adhesion and cell proliferation. It can also reduce the inflammatory state of LPS-stimulated pulp fibroblasts observed in gram-negative bacterial infections. These effects suggest a novel use of PGA-α-MSH as an anti-inflammatory agent in the treatment of endodontic lesions. To better understand these results, we have also used the multilayered polyelectrolyte films as a reservoir for PGA-α-MSH by using not only PLL (poly-l-lysine) but also the Dendri Graft poly-l-lysines (DGLG4) to be able to adsorb more PGA-α-MSH. Our results indicated clearly that, by using PGA-α-MSH, we increase not only the viability of cells but also the proliferation. We have also analyzed at the nanoscale by atomic force microscopy these nanostructured architectures and shown an increase of thickness and roughness in the presence of PGA-α-MSH incorporated into the multilayered film (PLL-PGA-α-MSH)10or (DGLG4-PGA-α-MSH)10in accordance with the increase of the proliferation of the cells growing on the surface of these architectures. We report here the first use of nanostructured and functionalized multilayered films containing α-MSH as a new active biomaterial for endodontic regeneration.

The aim of this study was to evaluate the quality of the current treatment of patients presenting with ruptured abdominal aortic aneurysms (RAAAs), from the first symptoms to the operating room with an analysis of preoperative mortality risk factors.

Conventional open surgery is still important beside endovascular surgery in the management of abdominal aortic aneurysms, with less reinterventions in the long-term follow-up. Incisional hernias are the major complication open surgery in the mid- and long term. The occurrence of this late complication could be due to the choice of the incision, median or transverse. The objectives of our retrospective and bicentric study were to characterize the long-term risk factors for incisional hernias after open surgery for abdominal aortic aneurysms, in particular by comparing the 2 types of laparotomy, and to determine the prevalence of the operated and not operated incisional hernias.

Nutcracker syndrome can cause disabling chronic pain requiring surgical intervention. At present, data describing a straightforward management approach are lacking. Transposition of the left gonadal vein is one of the surgical therapeutic alternatives. The aim of the present study was to describe our clinical results with gonadal vein transposition.

Current decision about when to operate abdominal aortic aneurysms (AAAs) is based only on the maximum aneurysm diameter (MAD). However, small aneurysms still rupture and we can observe very large AAA without any symptom. A simple morphologic analysis could be a tool to assess the risk of rupture.
