Habitual street food intake and subclinical carotid atherosclerosis.
2013
Street food (SF) is defined as out-of-home food consumption, and generally consists of energy-dense meals rich in saturated fats and poor in fibers, vitamins and antioxidants. Though SF consumption may have unfavorable metabolic and cardiovascular effects, its possible association with atherosclerosis has not been considered. The association between habitual SF consumption and asymptomatic carotid atherosclerosis, defined as the presence of plaques and/or increased intima-media thickness, was therefore investigated. One thousand thirty-five randomly selected adult participants without known diabetes and atherosclerotic cardiovascular diseases were cross-sectionally investigated in Palermo, …

Flow diversion for indirect carotid-cavernous fistula: Still an off-label indication?
2023
Background: Flow diversion (FD) is an established treatment for large or giant wide-necked unruptured intracranial aneurysms. In the past few years, the use of flow diverter devices was extended to several other “off-label” indications, including solitary or adjunctive treatment to coil embolization for direct (Barrow A type) carotid cavernous fistulas (CCFs). The use of liquid embolic agents still represents the first-line treatment for indirect CCFs. Typically, the ipsilateral inferior petrosal sinus or superior ophthalmic vein (SOV) is the preferred transvenous routes to access CCFs. In some cases, vessel tortuosity or different features make the endovascular access challenging, thus re…
Necessary Catheter Diameters for Mechanical Thrombectomy with ADAPT
2017
BACKGROUND AND PURPOSE: Large-bore catheters allow mechanical thrombectomy in ischemic stroke by engaging and retrieving clots without additional devices (direct aspiration first-pass technique [ADAPT]). The purpose of this study was to establish a model for minimal catheter diameters needed for ADAPT. MATERIALS AND METHODS: We established a theoretic model for the calculation of minimal catheter diameters needed for ADAPT. We then verified its validity in 28 ADAPT maneuvers in a porcine in vivo model. To account for different mechanical thrombectomy techniques, we factored in ADAPT with/without a hypothetic 0.021-inch microcatheter or 0.014-inch microwire inside the lumen of the aspiration…
Síndrome de Horner como manifestación de disección carotídea
2011
Caso Clínico: Un varón de 42 años se presenta con ptosis y miosis izquierda después de una historia de cefalea homolateral de 20 días de evolución, que empeora progresivamente durante los últimos días. Una angioresonancia revela disección de la arteria carótida interna. Discusión: El «síndrome de Horner doloroso» destaca como una urgencia médica por posible manifestación de una disección carotídea. Consideramos que el perfecto conocimiento de las urgencias neurooftalmológicas es de gran necesidad para el médico oftalmólogo y que estas requieren una atención multidisciplinaria para asegurar un seguimiento y tratamiento adecuado. Clinical Case: A 42-year-old man presented with ptosis and mios…
Relazione tra indice di resistenza renale e severità dell’aterosclerosi carotidea in soggetti con ipertensione arteriosa.
2014
RAZIONALE. L’indice di resistenza intraparenchimale renale (IR), valutato mediante eco-color-Doppler, è stato classicamente considerato mera espressione di resistenza vascolare distrettuale renale. Studi più recenti, tuttavia, hanno mostrato come tale indice sia anche influenzato da fattori a tergo, compliance vasale in primis, a prova di un suo possibile ruolo quale marker di alterazioni vascolari sistemiche. Diversi studi hanno dimostrato, inoltre, come lo spessore intimale (IMTc) e la placca a livello carotideo, valutati mediante ultrasonografia, siano documentati marcatori di danno d'organo subclinico nonché espressioni progressive di malattia aterosclerotica. Scopo del nostro studio è …
SILENT EMBOLIC INFARCTS ON COMPUTED TOMOGRAPHY BRAIN SCANS AND RISK OF IPSILATERAL HEMISPHERIC EVENTS IN PATIENTS WITH ASYMPTOMATIC INTERNAL CAROTID …
2009
OBJECTIVES: This study tested the hypothesis that silent embolic infarcts on computed tomography (CT) brain scans can predict ipsilateral neurologic hemispheric events and stroke in patients with asymptomatic internal carotid artery stenosis. METHODS: In a prospective multicenter natural history study, 821 patients with asymptomatic carotid stenosis graded with duplex scanning who had CT brain scans were monitored every 6 months for a maximum of 8 years. Duplex scans were reported centrally, and stenosis was expressed as a percentage in relation to the normal distal internal carotid criteria used by the North American Symptomatic Carotid Endarterectomy Trialists. CT brain scans were reporte…
UTILITÀ DI UN BASSO CUT-OFF DI INDICE DI RESISTENZA INTRARENALE NEL PREDIRE ALTERAZIONI VASCOLARI SISTEMICHE PRECOCI IN SOGGETTI CON IPERTENSIONE ART…
2014
Studi recenti mostrano come l’indice di resistenza intraparenchimale renale (IR), classicamente considerato espressione di resistenza vascolare renale, possa avere un importante ruolo quale marker di alterazioni vascolari sistemiche. Il valore soglia di IR il più spesso utilizzato per identificare pazienti con maggiore probabilità di danno d’organo e di mortalità è stato 0.70. Non è stato tuttavia verificato se un cut-off più basso abbia una maggiore capacità di identificare alterazioni vascolari sistemiche subcliniche. Scopo del nostro studio è pertanto quello di determinare, in soggetti con ipertensione arteriosa essenziale (EH), il valore di IR renale che meglio predica l’esistenza di un…
Atypical posterior circulation strokes: a case-based review of rare anatomical variations involved
2021
The circle of Willis is a very important vascular mechanism of protecting against cerebral ischemia, especially when circulation within the main arteries irrigating the brain is somehow impeded. As result of congenital malformation arising early in embryonic development, the fetal-type posterior circle of Willis remains as such during the rest of one's life. Consequently, the posterior cerebral artery (PCA) becomes a branch of the internal carotid artery (ICA), rather than of the basilar artery (BA). Furthermore, the rest of collateral circulation, between the anterior and the posterior regions of the brain, is also negatively affected (e.g., leptomeningeal vessels). The anatomical variant …
Effect of Oral Semaglutide on Cardiovascular Parameters and Their Mechanisms in Patients with Type 2 Diabetes: Rationale and Design of the Semaglutid…
2022
Type 2 diabetes (T2D) management has reached a point where not only optimal glycaemic control is necessary, but also additional interventions with proven cardiovascular risk reduction benefit. Subcutaneous semaglutide has been shown to provide cardiovascular protection, but its use may be limited by its injection formulation. To overcome this limitation, an oral semaglutide tablet has been developed, which could potentially be of the same value as its injection counterpart, but in a much wider group of patients with T2D, thereby allowing for broader cardiovascular risk reduction in this vulnerable patient population.A total of 100 consecutive patients with T2D and a disease duration of up t…
