Transcervical approach for carotid artery stenting with transitory reversal flow: Case report

2021

Introduction Carotid artery stenting (CAS) has been indicated as an alternative to carotid endarterectomy in high risk patients. Sometimes, an aortic arch can be anatomically unfavourable for CAS. Herein we report our experience in a case of CAS with transcervical approach. Presentation of case A 77-year-old male was referred to our hospital for severe subtotal occlusion of the left internal carotid artery. He had a past medical history of radiation to the head and neck for laryngeal cancer. Previous CT-angiography had shown a type III aortic with bovine arch. CAS via transcervical approach was performed with transitory reversal flow during the placement of RX Spider Filter 6 Fr (Medtronic,…

Treatment of isolated ascending aortic aneurysm by off-pump epiaortic wrapping is safe and durable.

2016

OBJECTIVES: Isolated ascending aortic aneurysm (iAA) is usually treated by open graft repair requiring sternotomy, cardiopulmonary bypass (CPB) and cardioplegia. This approach carries significant mortality in older patients or those presenting with comorbidities. We report an original series of patients presenting with iAA and treated with epiaortic wrapping by using a synthetic mesh. This less invasive aortic repair technique allows reducing the aortic diameter to a predefined value and is performed without CPB. METHODS: Data from patients presenting with an iAA and treated with the wrapping technique (WT) by polypropylene/polyester mesh from November 2006 to July 2015 were collected. The …

La flora vascolare e lichenica della Riserva Naturale Grotta Conza (Sicilia nord-occidentale). – Naturalista sicil., s. 4, 33 (1-2): 3-68.

Vascular and lichenic flora of Grotta Conza Nature Reserve (NW Sicily). Based on field investigation, bibliographic and herbarium researches we present a vascular and lichen flora of Grotta Conza Nature Reserve, a protected area of speleological and antropological interest located along the northern slopes of Pizzo Manolfo, very close the city of Palermo. The main outcrops of the area are represented by limestones of mesozoic and tertiary origin, while, bioclimate can be referred to thermomediterranean thermotype with subhumid ombrotype. Landscape, strongly influenced by the past prolonged historical utilization of the territory, shows total absence of primary woodlands, whose place is now …

Mortality of ruptured abdominal aortic aneurysm with selective use of endovascular repair

2009

The aim of this review was to examine the results over a seven-year period of treatment for ruptured abdominal aortic aneurysm (RAAA). From 2002 on, our tertiary referral centre offered both open and endovascular (EVAR) treatment modalities for RAAA. All patients with a proven RAAA who were admitted into our hospital were included. Primary outcome measure was surgical mortality. In total 261 patients were admitted with suspicion of acute AAA. Of these, 175 (67%) had a RAAA, confirmed by computed tomography-scanning or at laparotomy. One hundred and fifty-nine patients (90.9%) were treated, 114 by open repair and 45 by EVAR. Overall mortality of patients treated was 25.2%, with an open repai…

Carotid artery stenting in patients with brain meningioma.

2014

The association between carotid artery stenosis and brain meningioma is rather rare. Indeed, data in literature about this association are scarce and potential risks of carotid artery stenting using different protection devices are not known. We describe the endovascular treatment of severe carotid stenosis in two patients with intracranial meningioma.Riassunto L’associazione tra stenosi carotidea e menigioma cerebrale è piuttosto rara. Di conseguenza I dati su questa associazione sono scarsi in letteratura, e non sono noti i rischi potenziali dello stenting carotideo con l’uso di diversi apparati di protezione. Descriviamo il trattamento endovascolare di una stenosi carotidea serrata in du…

Altered expression of inflammation-related genes in human carotid atherosclerotic plaques.

2011

Abstract Objective Inflammation is a pivotal process in atherosclerosis development and progression, but the underlying molecular mechanisms remain largely obscure. We have conducted an extensive expression study of atherosclerotic plaques to identify the inflammatory pathways involved in atherosclerosis. Methods We studied 11 human carotid plaques, their respective adjacent regions and 7 control arteries from different subjects. Expression of 92 genes was studied by TaqMan low-density array human inflammation panel. Human aortic endothelial and smooth muscle cells were used for in vitro experiments. Results The mRNA levels of 44/92 genes (48%) differed significantly between the tissues exa…

Inquadramento clinico del paziente vasculopatico

2022

Le patologie vascolari sono uno dei più rilevanti problemi per la sanità nazionale e quindi rappresentano una importante branca della medicina. I segni, le manifestazioni e le evoluzioni delle malattie vascolari vanno spesso integrati con altre patologie capaci di influenzarne il percorso. L’aumento della durata della vita, con il conseguente invecchiamento della popolazione, rende il paziente vasculopatico una figura presente costantemente negli ambulatori di medicina. I dati dell’Istituto Nazionale di Statistica (ISTAT) riportano che in Italia l’età media della popolazione è di 44,9 anni e che la fascia di popolazione con età superiore a 65 anni è del 22,3%. Inoltre l’Italia è il Paese ch…
