A clampless and sutureless aortic anastomosis technique using an endograft connector for aortoiliac occlusive disease in which the aorta cannot be cl…
2012
Bypass surgery in aortoiliac or aortofemoral occlusive disease can be technically demanding and hazardous due to huge calcifications and/or patient co-morbidities. We report about mid-term results of a telescoping sutureless aortic anastomosis technique using endografts as connectors to address such challenging situations. This is a single-center experience (2004–2011) in seven patients (63 ± 6 years) requiring aortoiliac (three) or aortofemoral (four) bypass surgery. In six cases, an aortic stent graft was telescoped into the infrarenal aorta and partly deployed within the aorta and partly outside the aorta. In the first case, a bifurcated stent graft was deployed and the iliac legs were p…

Arteriopatie viscerali
2022
Le malattie delle arterie viscerali e renali sono sempre di più frequente osservazione per il chirurgo vascolare. Il progressivo invecchiamento della popolazione e il costante progresso tecnologico, in particolare della diagnostica per immagini, sicuramente hanno contribuito a un più frequente riscontro di queste patologie. Per quanto riguarda la patogenesi, la malattia aterosclerotica è la causa più frequente per entrambi i distretti arteriosi analizzati. I recenti progressi delle procedure endovascolari hanno ulteriormente migliorato la prognosi di queste malattie arteriose permettendo di trattare patologie complesse con procedure sempre meno invasive, e la conoscenza di queste moderne te…
Tips and tricks to make the ascending aorta accessible to EVAR
2012
The ascending aorta is gaining increasing interest for endovascular specialists, as it opens the door to a potentially better way to treat aortic arch pathologies. Landing safely a stentgraft into the ascending aorta allows downgrading significantly the invasiveness of conventional open repair of the ascending aorta and/or aortic arch. Unfortunately, accessibility to the ascending aorta, in order to perform EVAR, can be challenging as the transfemoral approach might be cumbersome, or because the ascending aorta might not be appropriate for stentgraft landing. This paper will present some technical tips and tricks to achieve successful stentgraft landing in zone 0.
Expression of inflammation-related genes in human atherosclerotic plaques
2010
Aims: Atherosclerosis is an inflammator y disease which molecular mechanisms are not been completely investigated. Our aim is to perform a wide expression study of inflammation related genes in human atherosclerotic plaques. Methods: The Human Inflammation Array (Applied Biosystems) was used to perform the mRNA quantification of 92 inflammation-related genes in 12 atherosclerotic plaques, their respective adjacent regions (with a lower grade lesion) and 7 healthy ar teries. The principle of the array is the real-time PCR amplification with a TaqMan probe specific for each gene. Data analysis was performed with SDS 2.3 software with the comparative Ct method using the gene beta-2-microglobulin as h…

Trattamento immunomodulante delle lesioni pre-cancerose della cervice uterina ( LSIL ) con beta-glucani
2014
Il tumore della cervice uterina rappresenta oggi l'esempio più eclatante di neoplasia associata a fattori immunologici. Uno dei fattori di rischio principali di tale malattia è, infatti, l'infezione da HPV ( Human papillomavirus). L'incidenza di tale infezione risulta essere direttamente proporzionale all'entità della lesione neoplastica arrivando a toccare quota 89% nel cancro invasivo della cervice. Lo scopo del nostro lavoro è stato quello di osservare come un aumento della risposta immunitaria cellulo-mediata indotta dai Beta-glucani possa influenzare la risoluzione delle lesioni precancerose di basso grado della cervice uterina ( LSIL ). Sono state prese in considerazione, dal 2009 al …
Nanofibrillar scaffold resists to bile and urine action: experiences in pigs
2020
Biomaterial-based-scaffolds’ functions are to replace anatomical and functional features loss of an injured tissue. They can replace native tissue after their reabsorption. Material and methods. In our experimental procedures we utilized the PHEA-PLA+PCL scaffold in 2 female pigs to assess its resistance to bile and urine. Results. Both pigs survived to surgical procedures. After a month fibres appeared unchanged in term of form and dimension at electronic microscopy. Cells and ECM factors were founded inside the scaffold in a microscopical evaluation. Conclusion. Planar and tubular scaffolds were colonized by cells and extracellular matrix elements. The study conducted on pig suggested tha…
The Role of Early Revascularization and Biomarkers in the Management of Diabetic Foot Ulcers: A Single Center Experience
2022
Diabetic neuropathy and Peripheral Arterial Disease (PAD) are the main etiological factors in foot ulceration. Herein, we report our experience of diabetic foot ulceration (DFU) management, with an analysis of the relationship between the rate of lower extremity amputation, in persons with infected DFU, after revascularization procedures performed to prevent major amputation. This study highlights the role of different biomarkers, showing their usefulness and potentiality in diabetic foot ulcer management, especially for the early diagnosis and therapy effectiveness monitoring. A retrospective analysis, from September 2016 to January 2021, of diabetic patients presenting diabetic foot with …
