Delay between symptoms and surgery for carotid artery stenosis: modification of our practice.
2014
Recent data from the literature concerning symptomatic carotid stenosis show that the long-term benefits of surgery are greater when the surgery is performed soon after the neurologic event, ideally within 2 weeks. Since 2009, following recommendations, we decided to perform surgery as quick as possible. The aim of the study was to determine whether this approach increased postoperative morbimortality and the way it could change our practice.Using a prospective database containing a consecutive and continuous series of 1,500 carotid endarterectomies performed between 2003 and 2012, we extracted the records concerning the 417 symptomatic carotid stenoses (27.8%). We compared the 30-day and l…
Long-Term Results of Stenting of the Aortic Bifurcation
2012
Background To evaluate the long-term results in a multicentric continuous series of narrowing lesions of the aortic bifurcation treated with a kissing stent. Methods From January, 1st 1999 to the December, 31st 2001, all of the patients ( n = 80) presenting with stenosis of the aortic bifurcation ( n = 15) and/or the 2 common iliac arteries ( n = 65), treated with a kissing stent, in 8 teaching hospitals were collected retrospectively. The risk factors were smoking (91%), dyslipidemia (60%), arterial hypertension (42%) and diabetes (27%). In 84% of cases, the indication for treatment was claudication. The lesions were stenotic n = 76) and/or thrombotic ( n = 18). The associated lesions were…
Specific enrichment of 2-arachidonoyl-lysophosphatidylcholine in carotid atheroma plaque from type 2 diabetic patients
2016
IF 3.942; International audience; Background and aims: Diabetic patients are at high risk of stroke and coronary artery disease. Recent data suggest that arachidonic acid metabolism is altered in diabetic conditions and that these alterations contribute to accelerated atherosclerosis. Little is known about how these alterations affect the metabolism and the proportions of different lipid species within the atherosclerotic plaque. The aim of our study was to perform a targeted lipidomic analysis of human atherosclerotic lesions, with a specific focus on PUFA-containing lipid species, to reveal differences in the fatty-acid composition of plaque in diabetic patients compared with non-diabetic…
High incidence of venous thrombosis after surgery for abdominal aortic aneurysm
2009
Objective The incidence of venous thromboembolism (VT) after aortic abdominal aneurysm (AAA) surgery is imprecisely reported. On one hand, thromboprophylaxis has improved, on the other hand, AAA patients have become older and/or present worse comorbidities. Herein, we prospectively analyzed the incidence of VT in a continuous series of patients operated on for AAA repair and looked for predictive factors. Materials and Methods Between January 1, 2005, and December, 31, 2006, 193 consecutive patients (177 men and 16 women), mean age 73 (range, 47-93) underwent elective AAA repair, 137 open (71%) and 56 endovascular (29%), in our institution. Thromboprophylaxis consisted of thigh-length compr…
Development of Abdominal Aortic Aneurysm Is Decreased in Mice with Plasma Phospholipid Transfer Protein Deficiency
2013
International audience; Plasma phospholipid transfer protein (PLTP) increases the circulating levels of proatherogenic lipoproteins, accelerates blood coagulation, and modulates inflammation. The role of PLTP in the development of abdominal aortic aneurysm (AAA) was investigated by using either a combination of mechanical and elastase injury at one site of mouse aorta (elastase model) or continuous infusion of angiotensin II in hyperlipidemic ApoE-knockout mice (Ang II model). With the elastase model, complete PLTP deficiency was associated with a significantly lower incidence and a lesser degree of AAA expansion. With the Ang II model, findings were consistent with those in the elastase mo…
