Delay between symptoms and surgery for carotid artery stenosis: modification of our practice.
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…
Mycotic Aneurysm of Both Internal Iliac Arteries due to Candida albicans.
International audience; : We report the case of a 21-year-old man, with a Candida-related endocarditis causing multiple emboli and bilateral false aneurysms of the internal iliac arteries. As the distal runoff vasculatures of both internal iliac arteries were occluded, these arteries required ligation. Although there were few consequences with the procedure, multiple emboli and recurrence of endocarditis after cardiac surgery led to the patient's death.
Long-Term Results of Stenting of the Aortic Bifurcation
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
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…
Development of Abdominal Aortic Aneurysm Is Decreased in Mice with Plasma Phospholipid Transfer Protein Deficiency
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…
