OBJECTIVE To establish the risk of carotid artery stent (CAS) complications in patients with aortic arch anomalies. METHODS In a prospective series of patients submitted to CAS, all cases with arch anomalies were compared with cases with normal arch anatomy (type I, II and III) in order to assess the impact of anatomic characteristics on technical and(More)
A well-functioning vascular access for hemodialysis plays a key role in the quality of life and clinical outcome of dialysis patients. A vascular access for dialysis is considered to be adequate when it provides a blood flow of at least 250 ml/min in the standard dialysis and up to 350-400 ml/min in the high-efficiency dialysis. So far, Cimino-Brescia(More)
OBJECTIVE To evaluate the peri-operative results of Anaconda endograft in the first 49 cases treated in a single centre. METHODS The study was carried out prospectively on cases of infrarenal abdominal aortic aneurysm (AAA) treated with Anaconda endograft. The characteristics of the proximal aortic neck and of the iliac access vessels were considered. The(More)
PURPOSE The purpose of this study was to analyze mode of presentation, surgical treatment, and early and long-term results of a series of extracranial internal carotid artery aneurysms (EICAA). METHODS A retrospective analysis was performed on all cases treated for EICAA in a single institution from March 1974 to March 1995. Patient follow-up was obtained(More)
INTRODUCTION Indication to carotid revascularisation is commonly determined by percent of stenosis as well as neurological symptoms and clinical conditions. High plaque embolic potential is defined as 'vulnerability'; however, its characterisation is not universally used for carotid revascularisation. We investigated the role of contrast-enhanced(More)
OBJECTIVE Persistent type II endoleaks (ELIIp, ≥6months) after an endovascular aneurysm repair (EVAR) can be associated with adverse outcomes. The aims of this study are the evaluation of the incidence of ELIIp, their pre-operative morphological predictive features (PMF) and the post-EVAR abdominal aortic aneurysm (AAA) evolution in the presence of ELIIp.(More)
OBJECTIVE The objective of this study was to evaluate early and late results of the Anaconda aortic endograft (Vascutek, Terumo, Inchinnan, Scotland) in a single-center experience. METHODS From September 2005 to March 2012, patients underwent endovascular aortic repair for abdominal aortic aneurysm (AAA) with Anaconda endograft were prospectively enrolled(More)
INTRODUCTION this prospective study defines the immune response to fresh arterial homograft replacement for graft infection. MATERIALS AND METHODS ten patients who underwent ABO-compatible homograft transplantation were studied for anti-HLA antibody production, and CD3-CD4-CD8-positive lymphocytes subset. Immunological studies were performed(More)
BACKGROUND The main histopathological features of abdominal aortic aneurysm (AAA) are tissue proteolysis mediated by matrix metalloproteinases (MMPs) and inflammation. This study aimed at verifying the presence and contribution of mesenchymal stromal cells (MSCs) to aneurysmal tissue remodeling. METHODS AND RESULTS MSCs were successfully isolated from the(More)
OBJECTIVE/BACKGROUND The influence of contralateral carotid occlusion (CCO) on the outcome of carotid endarterectomy (CEA) and stenting (CAS) is debated. This study aims to evaluate CEA and CAS results in patients with CCO. METHODS All carotid revascularizations from 2005 to 2011 were analyzed, focusing on the role of CCO on 30-day cerebral events and(More)
