ASSOCIATION OF RENAL RESISTIVE INDEX WITH CAROTID INTIMA-MEDIA THICKNESS IN HYPERTENSIVE PATIENTS

Incidence and prognostic factors related to major adverse cerebrovascular events in patients with complex aortic diseases treated by the chimney tech…

Abstract Objective Endovascular aneurysm repair (EVAR) with the chimney technique (ch-EVAR) has been used for the treatment of aortic aneurysms as an alternative approach to fenestrated endografting or open repair. Nonetheless, the need for an upper extremity arterial access may contribute to a higher risk for periprocedural cerebrovascular events. This study reports on the perioperative cerebral and major adverse cardiac and cerebrovascular events (MACCE) after ch-EVAR. Methods The PERICLES registry (PERformance of the chImney technique for the treatment of Complex aortic pathoLogiES) is an international, retrospective multicenter study evaluating the performance of ch-EVAR for the treatme…
Collected World Experience About the Performance of the Snorkel/Chimney Endovascular Technique in the Treatment of Complex Aortic Pathologies
2015
OBJECTIVES: We sought to analyze the collected worldwide experience with use of snorkel/chimney endovascular aneurysm repair (EVAR) for complex abdominal aneurysm treatment. BACKGROUND: EVAR has largely replaced open surgery worldwide for anatomically suitable aortic aneurysms. Lack of availability of fenestrated and branched devices has encouraged an alternative strategy utilizing parallel or snorkel/chimney grafts (ch-EVAR). METHODS: Clinical and radiographic information was retrospectively reviewed and analyzed on 517 patients treated by ch-EVAR from 2008 from 2014 by prearranged defined and documented protocols. RESULTS: A total of 119 patients in US centers and 398 in European centers …
STIFFNESS AORTICA STIMATA MEDIANTE METODICA OSCILLOMETRICA E PROGRESSIONE DEL DANNO RENALE IN PAZIENTI IPERTESI NEFROPATICI
2022
Scopo del lavoro: Scopo principale del nostro studio è stato quello di analizzare la possibile relazione tra aumento della rigidità aortica e progressione della malattia renale cronica in un gruppo di pazienti ipertesi nefropatici, endpoint secondari riguardavano l’eventuale ruolo prognostico della pulse wave velocity (PWV) sugli eventi cardiovascolari (CV) e sulla mortalità totale. Materiali e metodi: sono stati arruolati 395 pazienti che sono stati sottoposti a esami bioumorali, monitoraggio ambulatoriale della pressione arteriosa e stima della stiffness aortica mediante dispositivo oscillometrico Arteriograph. Sono stati inoltre registrati i dati relativi all’insorgenza di eventi card…
Comparison of the strain field of abdominal aortic aneurysm measured by magnetic resonance imaging and stereovision: a feasibility study for predicti…
2015
International audience; The prediction of the risk of rupture of abdominal aortic aneurysm (AAA) is a complex problem. Currently the criteria to predict rupture of abdominal aortic aneurysms are aneurysm diameter and growth rates. It is generally believed that study of the wall strain distribution could be helpful to find a better decision criterion for surgery of aortic aneurysms before their rupture. The wall strain distribution depends on many biological and biomechanical factors such as elastic properties of the aorta, turbulent blood flow, anatomy of the aorta, presence of thrombus or not and so on. Recently, numerical simulations to estimate rupture-potential have received many attent…
FATTORI ASSOCIATI ALLA DISCORDANZA TRA ALTERAZIONI DELLA PULSE WAVE VELOCITY AORTICA E AUMENTO DELLO SPESSORE MIO-INTIMALE CAROTIDEO IN SOGGETTI IPER…
2014
Numerosi studi hanno dimostrato come lo spessore mio-intimale carotideo (IMTc), valutato mediante eco-color-Doppler, sia un importante marcatore di danno d’organo subclinico nonché espressione di alterazione vascolare sistemica. Recenti dati, d’altro canto, hanno evidenziato come anche la pulse wave velocity aortica (PWVa), nota misura di stiffness arteriosa, sia indice di precoce danno vasale. Pur dipendendo parzialmente da comuni fattori patogenetici, IMTc e PWVa non hanno un significato clinico del tutto sovrapponibile e risultano non raramente discordanti tra loro. Appare pertanto interessante identificare quali siano i fattori associati al divergente comportamento di tali parametri. So…
