PURPOSE To assess baseline and follow-up plasma concentrations of metalloproteinase-9 (MMP-9), MMP-2, and tissue inhibitor of metalloproteinase-2 (TIMP-2) in patients undergoing carotid thromboendarterectomy (TEA) in relation to tissue expression and diagnostic features. BASIC METHODS Using sandwich enzyme-linked immunosorbent assay, plasma levels of(More)
Intermittent claudication of the masticatory muscles is an unusual symptom sometimes described in association with temporal arteritis. We describe here two cases where this symptom was due to insufficient blood supply to the masticatory muscles caused by atherosclerotic changes of carotid vessels. In one of our cases surgical revascularization was followed(More)
PURPOSE To reduce the rates of morbidity and mortality in aortic graft infection, a new diagnostic approach is needed to help identify low-grade stages, specifically when there are minimal or no clinical signs of overt infection. The aim of this study was to evaluate the role of technetium 99m--hexametazime white blood cell scanning (99mTc scanning) in(More)
Inflammatory abdominal aortic aneurysms are characterized by dense perianeurysmal fibrosis involving the adjacent organs. Attempts to isolate the aneurysm can lead to operative injuries of these structures, thus increasing the rates of complications and mortality. In the last 12 years 45 patients with inflammatory abdominal aortic aneurysms underwent(More)
AIM Intraoperative cerebral embolization is a greater concern in patients undergoing carotid-artery stenting (CAS) than in those undergoing the reference standard treatment carotid endarterectomy (CEA). We evaluated cerebral embolism with diffusion-weighted magnetic resonance imaging (DW-MRI) and transcranial Doppler monitoring during CAS and CEA. METHODS(More)
We describe popliteal arterial adventitial cystic disease which causes intermittent claudication in a young athletic man, with atypical manifestation, without loss of foot pulses on knee flexion nor murmur in the popliteal fossa. The findings obtained from Magnetic Resonance Imaging were non-diagnostic. The diagnosis resulted from Echo-Doppler(More)
We have studied the kinetics of smooth muscle cell growth in the tunica media of human arteries obtained from 12 patients affected by obstructive vascular disease, and one case operated because of a trauma. The studies were carried out on arterial samples by autoradiography after in vitro labelling with 3H-thymidine. Different patterns of radioactive(More)
Cerebral embolization is still a major concern in patients undergoing transfemoral carotid artery stenting. Intraoperative transcranial Doppler (TCD) monitoring and diffusion-weighted magnetic resonance imaging (DW-MRI), two techniques currently used to study this phenomenon, have provided data suggesting the importance of aortic arch catheterization in(More)
The positive correlation between cerebral ischemia and carotid atherosclerosis of extracranial tract has been well established. The reliability of echotomography as diagnostic and prognostic tool in the evaluation of the carotid atherosclerotic lesions is now intensively investigated. Most of the attention has been payed to the accuracy in the determination(More)
Transfemoral filter-protected carotid artery stenting (CAS) has emerged as a valid alternative to carotid surgery. To overcome the drawbacks of femoral access for CAS and reduce embolic load, some have proposed cervical access with internal carotid artery (ICA) flow reversal. In a series of patients at high risk for femoral access who underwent(More)
