Early structural degeneration of Mitroflow aortic valve: Another issue in addition to the mismatch?

2018

We reported two cases of early structural valve degeneration (SVD) with Mitroflow prosthesis in aortic position in patients above the age of 65 years. Microscopic aspects have been analysed to investigate the intrinsic mechanism of SVD. New techniques to improve the structure and the preservation of this prosthesis are needed in order to reduce potential dangerous early complications.

SUCCESSFUL ARTERO VENOUS FISTULA USING CARDICA C-PORT xA SYSTEM IN AN ELDERLY UREMIC PATIENT. A CASE REPORT.

2008

INTRODUCTION AND AIMS: In artero venous fistula (AVF) hand-sewn anastomoses are considered the gold standard. These are performed generally with a double running suture. These suturing techniques yeld excellent results, despite being time-consuming, difficult to perform with small vessels, and associated with a significant learning curve. These device are intented to enable rapid, precise and reliable anastomoses in AVF without artery cross-clamping. METHODS: We report the case of a male 65 years old uremic patient with serious atherosclerosis that, in local anesthesia, underwent proximal AVF by mechanical anastomosis between cephalic vein and radial artery without arterious cross-clamping.…

Heterogenous forms of dyslipidemiain women with polycystic ovary syndrome

2008

Forms of dyslipidemia are very common in individuals affected by polycystic ovary syndrome (PCOS), but in addition to plasmatic lipids, it is necessary to evaluate the alterations in the atherogenic lipoproteins (Lp) and apolipoproteins (apo). In our study we measured the concentrations of apoB, Lp(a) and low density lipoproteins (LDL) in 42 patients with PCOS (age: 28 +/- 7 years, body mass index: 27 +/- 5 kg/m-) and 37 healthy women (of the same age and body mass index). Methods: values of Lp(a) >30 mg/dl were considered high, whereas for apoB, values >100 g/l were considered high. Results: the patients with PCOS showed an increase in triglycerides (p=0.0011) and low levels of high densit…

STUDIO DELL'ATTIVITA' ELETTRICA GASTRICA CON ELETTROGASTROGRAFIA IN NEONATI PRETERMINE

2000

Gli Autori hanno valutato la differenza dei dati elettrogastrografici basali in neonati a digiuno confrontando i nati a termine con i prematuri suddivisi in base alla età gestazionale in prima e dopo la 32ma settimana e in base alla presenza o meno di gemellarità. I dati raccolti consentono di concludere che le differenze riscontrate tra egg dei neonati a termine e dei prematuri sono da riportare ad alcuni fattori di rischio particolari. In effetti al di sopra di 32 settimane di gestazione e in assenza della gemellarità i dati sono sovrapponibili a quelli dei nati a termine.

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…

Experimental investigations on a model of cryogenic edema.

1987

The role of mechanisms underlying formation and progression of vasogenic brain edema is investigated. On this purpose, cerebral edema was produced by cortical freezing in two different brain situations in rabbits (with or without replacement of bone flap). BBB (Blood-Brain Barrier) breakdown was evaluated by observation of Evans blue extravation, while a histopathological evaluation was carried out by light and transmission electron microscopy. Water content of brain tissue was determined by the wet/dry weight ratio method. Comparison of extension and intensity of cerebral edema between these two groups of animals shows a statistically significant difference: there was evidence of higher wa…

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…

Intraparenchymal Brain Hemorrhage: "Birdlime" Effect Usefulness.
