Desarrollo de un modelo predictivo de mortalidad a largo plazo y complicaciones relacionadas con la endoprótesis, en la reparacion endovascular de an…

Desde el inicio de la reparación endovascular de aneurismas de aorta abdominal infra renal, la progresión de dicho tratamiento ha superado en numero al realizado anualmente mediante cirugía abierta convencional, en la mayoría de servicios de Cirugía Vascular. A ello ha contribuido principalmente la menor mortalidad operatoria los 30 días y al atractivo que supone para pacientes un procedimiento menos agresivo y para los profesionales, el ofrecer una alternativa en casos en los que la cirugía abierta sería inasumible por elevado riesgo. Sin embargo se pueden señalar dos puntos de controversia en dicha tendencia: -La menor tasa de mortalidad postoperatoria, puede hacer que se ofrezcan alterna…

MR-Angiographie peripherer Gefäße mit automatischer Verschiebetisch-Technik bei 1.0 T im Vergleich zur i. a. DSA

1999

PURPOSE Contrast-enhanced (CE) 3D-MR angiography of peripheral arteries was performed in 8 patients with peripheral arterial occlusive disease by applying a new tracking technique on a 1.0 T system (Magnetom Harmony, Siemens). The studies were compared with intra-arterial digital angiography as gold standard. MATERIALS AND METHODS Imaging of the distal aorta, pelvis, upper and lower limb arteries was accomplished with a Flash-3D-sequence (TR/TE = 6.2/3.2 ms) within 26 s acquisition time of each region after a single bolus of 30 ml contrast agent. Individual circulation time was determined by a test bolus before each examination. RESULTS 112 vessel segments were evaluated. MR angiography ach…

Análisis tiempo-frecuencia de la fibrilación ventricular. Estudio experimental

2006

Introduction and objectives. The analysis of frequency variability during ventricular fibrillation has yielded inconsistent results. We used an experimental model of ventricular fibrillation, with a short timescale, to analyze variations in frequency and their associated spatial distribution. Methods. Epicardial recordings of ventricular fibrillation were made in 10 perfused isolated rabbit heart preparations using a multiple electrode system (i.e., 240 unipolar electrodes). Both spectral and time-frequency analysis were used to derive the dominant frequency in the anterolateral wall of the left ventricle. Results. Linear regression analysis showed that there was a good correlation between …

Haemorheological components in the pre-geriatric and geriatric age range in a randomly selected Western Sicily population sample (Casteldaccia study)

1993

{Received 24.8.1992; accepted 7.12.1992} On a randomly selected western Sicily population sample (Casteldac­ cia Study: 600 subjects; 300 males and 300 females) of an age range from 40 to 79 years, were determined: Haematocrit (Htc) , blood vi­ scosity, plasma viscosity, filterability of whole blood and fibrinogen. Par­ ticipation was 97%, being 582 subjects (M = 287, F = 295). All the parameters measured showed a progressive increase with age and si­ gnificant differences were found between male and female subjects: Htc and blood viscosity were higher in male subjects (p < 0.01), while plasma viscosity, whole blood filterability and fibrinogen were higher in female subjects (p < 0.05). In …

Imaging funzionale per diffusione (DWI) e ischemia cerebrale in fase acuta: Potenzialità diagnostiche e confronto con metodiche convenzionali

1997

Stroke is the third leading cause of death and is a major cause of long-term disability. Neuroprotective treatment within a 4-hour «therapeutic window» has proved highly efficacious in reducing morbility and mortality in animal model. It is with this background that the need for emergent diagnosis and therapy of acute stroke in strongly suggested. Computed tomography (CT) shows the parenchymal changes of acute stroke too late to be helpful, and its role has been primarily to evaluate the possibility of intracerebral or subarachnoid hemorrhage. While conventional magnetic resonance (MR) imaging can demonstrate parenchymal abnormalities 4–6 hours after ischemia, newer techniques such as diff…

Un parcours de soins primaires pour améliorer la prise en charge et le pronostic des patients diabétiques avec une plaie de pied

2021

Resume Introduction Les plaies de pied diabetique (PPD) sont un probleme frequent, associe a un risque eleve d’amputation et de mortalite. L’adressage rapide a une structure specialisee du pied diabetique permet d’ameliorer le taux de cicatrisation et de diminuer le risque d’amputation. Une proportion importante de patients avec une PPD sont adresses tardivement vers ces structures specialisees. Un parcours de soins primaires des patients avec une PPD a ete developpe par l’International Diabetic Foot Care Group en collaboration avec le D-Foot International pour ameliorer l’orientation de ces patients vers les structures specialisees. Nous presentons une version adaptee au systeme de soin fr…
