Appropriateness of surgery performed for abdominal aortic aneurysm at tertiary hospitals in Spain

2021

Background: The aim of this study was to analyze the appropriateness of the type of repair (open or endovascular) performed for abdominal aortic aneurysm (AAA) in five university hospitals in Spain, according to evidence-based recommendations. Methods: A multicenter, retrospective cross-sectional study of patients with AAA who underwent elective open surgical repair (OSR) or endovascular aneurysm repair (EVAR). Data were collected on demographic and clinical variables and type of surgical repair. A pair of vascular surgeons from each participating hospital performed a blinded assessment based on GRADE recommendations. The concordance between the two evaluators and the agreement between thei…

RED BLOOD CELL DISTRIBUTION WIDTH PREDICTS MORBIDITY AND MORTALITY AFTER AORTIC VALVE REPLACEMENT

2014

Objective: Red blood cell distribution width (RDW), is a measurement of the size variation as well as an erythrocyte heterogeneity index (i.e., anysocytosis). used in combination with the mean corpuscular volume for anemia diagnosis. However, it is emerging as an useful predictor biomarker of mortality and morbidity of cardiovascular diseases. However, until now no literature data there are about the RDW role in predicting mortality after aortic valve replacement (AVR). Thus, in this pilot study biological significance of elevated RDW values in early outcome following AVR was evaluated Methods: We enrolled 75 patients (mean age 73.5 ±7.9 years) subjected to AVR and/ or not co temporally to …

Wewnątrznaczyniowe dwuetapowe leczenie tętniaków aorty brzusznej z użyciem Heli-FX EndoAnchor System

2019

Wstęp: Wyniki leczenia tętniaków aorty brzusznej mimo wprowadzenia nowych technik wewnątrznaczyniowych nadal nie zawsze są zadowalające. Szczególnie trudną grupą pacjentów są osoby z krótką oraz stożkową szyją. W tej grupie chorych często występuje w okresie pooperacyjnym przeciek typu I. Jedną z metod mających temu powikłaniu zapobiec jest zastosowanie wkrętów wewnątrznaczyniowych Heli-FX. Ma to zwiększyć przyleganie systemu stentgraftu do ściany aorty brzusznej oraz zapobiec jego ewentualnej migracji. Materiał i metody: Autorzy niniejszego artykułu proponują zastosowanie leczenia dwuetapowego. Pierwszy etap stanowiła implantacja przedłużki aortalnej tuż poniżej odejścia tętnic nerkowych i…

RELAZIONE TRA ENDOTELINA-1 PLASMATICA E STIFFNESS AORTICA IN PAZIENTI IPERTESI CON MALATTIA RENALE CRONICA

2012

Vari studi hanno dimostrato come la stiffness arteriosa aumenti con il progressivo deterioramento della funzione renale. Una correlazione inversa è stata altresì dimostrata fra livelli plasmatici di endotelina-1 (ET-1) e filtrato glomerulare (GFR). Dati sperimentali hanno evidenziato che l’infusione di ET-1 è seguita da un incremento della stiffness arteriosa ed il trattamento con antagonisti del recettore ET-A dell’ET-1 in pazienti nefropatici ha comportato una riduzione della rigidità aortica, in parte indipendentemente dagli effetti sulla pressione arteriosa. Pochi dati esistono in letteratura sulle relazioni tra distensibilità aortica e concentrazioni plasmatiche di ET-1 in pazienti con…

Relazioni tra stiffness aortica ed indice di resistenza intrarenale nell’ipertensione arteriosa

2012

Per molti anni lo studio mediante eco-color-doppler dei parametri semiquantitativi emodinamici renali è stato utilizzato per rilevare le alterazioni della perfusione del rene trapiantato, per la diagnosi della stenosi dell’arteria renale o per valutare la progressione di alcune nefropatie. Più recentemente è stato osservato che tali parametri, ed in particolare l’indice di resistenza intrarenale (IR), non sono soltanto espressione della perfusione parenchimale, ma sono associati anche ad alterazioni morfo-funzionali sistemiche dell’albero vascolare. Vari studi hanno dimostrato come la stiffness aortica vada aumentando con il progressivo deterioramento della funzione renale. Tuttavia, dati c…

Genetic Factors as Promising Biomarkers of Sporadic Ascending Aortic Aneurysm

2014

Thoracic aorta shows various changes with advancing age and a progressive deterioration in structure and function. As a result, vascular remodeling (VR) and medial degeneration (MD) occur. VR and MD are typical entities of sporadic thoracic aortic aneurysm (TAA), actually considered a common and serious health risk and a pathology by unclear mechanisms. Increased activity of the coagulation system, inflammation, activation of extracellular matrix remodeling and endothelial dysfunction pathways have been recently evidenced to have a key role in its onset. Thus, polymorphisms of the coagulation system [fibrinogen (rs1800790); Factor II ( rs1799963); Factor V (rs6025); Factor VII (rs121964926)…

Periscope endograft technique to revascularize the left subclavian artery during thoracic endovascular aortic repair.

2013

Purpose: To present early and midterm results of the periscope endograft (PG) technique to maintain left subclavian artery (LSA) blood flow in thoracic endovascular aortic repairs (TEVAR) involving zone 3. Methods: From April 2010 to January 2013, 14 consecutive high-risk patients (11 men; mean age 7068 years, range 56–87) underwent TEVAR with the PG technique for 10 thoracic aortic aneurysms (TAA), 2 traumatic aortic ruptures, and 2 aortic dissections without a suitable landing zone (.2 cm distal to the LSA). Five procedures were performed emergently for rupture (3 TAAs and the 2 trauma cases). Two patients had a periscope deployed in an aberrant right subclavian artery. The periscope endo…

Pęknięty tętniak aorty zstępującej - duże wyzwanie dla niedużego ośrodka chirurgii naczyniowej

2018

Pacjentka, lat 76, została skierowana do Uniwersyteckiego Szpitala Klinicznego w Opolu z powodu podejrzenia rozwarstwienia aorty wstępującej i tamponady osierdzia. Przy przyjęciu chora w stanie ogólnym skrajnie ciężkim, z objawami głębokiego wstrząsu, niestabilna hemodynamicznie oraz wentylowana mechanicznie. W wykonanym doraźnie badaniu angio-TK stwierdzono rozwarstwienie aorty zstępującej z pękniętym tętniakiem w jej środkowym i dolnym odcinku oraz duży krwiak lewej jamy opłucnowej. Ze względu na znaczną szerokość aorty zstępującej, nawet w jej początkowym odcinku oraz aorty brzusznej powyżej pnia trzewnego do zaopatrzenia tętniaka potrzebne są dwa elementy stentgraftów o średnicy 46 mm. …
