Saccular ascending aorta aneurysm: report of an unusual presentation
No full textWe describe an unusual presentation of a large saccular aneurysm of the ascending aorta, mimicking an acute coronary syndrome. The compression of the aneurysm on the left main coronary artery was probably the cause of these confusing symptoms. Our experience confirms the fundamental role of modern cardiac imaging techniques in the differential diagnosis of these unusual cases and in the planning of the correct surgical procedure
Cardiac transapical approach: A new solution for the treatment of complex thoracic aortic disease
No full textAortic valve regurgitation secondary to ectopia and atresia of the left main coronary artery.
No full textCongenital atresia of the LMCA is an extremely rare anomaly which is often clinically complicated by silent angina, myocardial infarction, failure to thrive, or sudden cardiac death. Moreover, the atretic and ectopic origin of the LMCA associated with aortic valve anomalies is an even rarer condition. Herein, the case is described of a patient with a very rare association between the ectopic and atretic left main coronary artery (LMCA) and severe aortic valve regurgitation
Primary Endovascular Repair of the Ascending Aorta.
No full textDifferent case series have been published demonstrating the feasibility of endovascular repair of the ascending aorta in selected patients deemed unfit for open surgery. However, the use of commercially available stent graft in the ascending aorta remains off-label, and their excessive length often prevents their deployment in the ascending aorta. Here we report a case of successful primary endovascular repair of the ascending aorta using a physician modified off-the-shelf device
LONG- VERSUS SHORT-AXIS ULTRASOUND GUIDANCE FOR SUBCLAVIAN VEIN CANNULATION
No full textAIM. The aim of this study was to compare the short and long axis approaches to ultrasound
guided subclavian vein cannulation with respect to indicators of success.
METHODS. Patients (n = 46) undergoing cardiac surgery and requiring central venous
cannulation were randomised to undergo either long- or short-axis ultrasound-guided cannulation
of the subclavian vein by a skilled anesthesiologist. First pass success, number of
needle passes, procedural taken and complications were documented for each procedure.
RESULTS. The subclavian vein was successfully cannulated in all 46 patients.
The first pass success rate was higher in the short axis group 86 % compared to the long axis
group 56 % [24:28 (86 %) versus 10:18 (56 %) p = 0.043]. Procedural time was significantly
lower in the short axis (1.44 ± 1.11 versus 3.00 ± 2.01 min p = 0.002). Fewer
needle redirections were required in the short axis group (0.14 ± 0.36 versus 1.11 ± 1.13
p = 0.008).
CONCLUSIONS. The short-axis procedure was associated with a higher first pass success
rate, shorter procedure time and fewer needle redirections. A short-axis procedure for
ultrasound-guided subclavian cannulation offers advantages over long-axis procedure
Potere e libertà nella rete
No full textIl contributo si propone di analizzare alcune linee di tendenza nel rapporto rapporti tra potere e libertà in Internet: dopo aver sottoposto a critica alcune recenti ricostruzioni che enfatizzano la dimensione sociale e comunitaria della rete, lo scritto si sofferma su alcune problematiche attinenti al rapporto tra i privati utenti della rete, i grandi intermediari e i gestori delle piattaforme, e il potere pubblico. In particolare, per quanto attiene al ruolo di provider e gestori, si evidenzia l’esigenza di superare il mito della loro neutralità senza per questo configurare in capo ad essi forme di responsabilità editoriale, e valorizzando il ruolo che in questo senso può essere svolto dalle procedure c.d. di notice and take down; per quanto attiene al rapporto col potere pubblico, si valuta favorevolmente il tendenziale abbandono del ricorso allo strumento penale, e si evidenzia l’esigenza di privilegiare interventi normativi sulle modalità di diffusione dei contenuti, con specifico riferimento al tema della profilazione degli utenti finalizzata all’invio di materiale informativo, e all’esigenza di contrastare modalità non trasparenti di diffusione, quali quelle che si avvalgono di bot e fake account.The paper analyzes current trends in the relationship between Public Power and Internet Freedom. After having challenged recent theories about the social dimension of the Internet, the paper focuses on issues related to the relationship between private users, Internet intermediaries and platform providers, and Public Power. In particular, as far as the role of Internet intermediaries and providers is concerned, the Author argues that time is ripe to dispel the myth of their neutrality but warns that they should held liable as editors/publishers not just for this reason, and that the so called “notice and take down procedures” may play an important role in the field. As far as the relationship between Internet providers and Public Power is concerned, the Author agrees with those recommending setting aside the use of criminal law and highlights the need to support regulation on how contents are shared −considering the specific issue of users profiling− and to contrast non-transparent methods of dissemination of information such as those using bots and fake accounts
Immediate endovascular treatment of blunt aortic injury: Our therapeutic strategy
No full textBackgroundPosttraumatic aortic rupture is a potentially lethal injury. Endovascular procedure has recently proved to be a valid option. Timing of the treatment, however, is still a debated issue. We evaluated the feasibility and safety of immediate stent-graft repair of acute posttraumatic aortic injury.MethodsFrom 1998 to 2005, 15 patients (11 men and 4 women, mean age 42.3 years) with blunt aortic injury were treated with immediate stent-graft positioning. In patients with clinical and radiologic signs of impending rupture, endovascular treatment was performed in an emergency setting (11 cases). In the 4 remaining patients the aortic lesion was treated after clinical management. When present, immediate life-threatening nonaortic lesions were treated before endovascular stenting (6 cases). In 1 case emergency laparotomy and endovascular procedure were performed simultaneously. Stent positioning was monitored by intraoperative transesophageal echocardiography in all cases.ResultsEndovascular procedure was successful in 100% of the patients. Two patients died perioperatively as a consequence of a multiorgan failure. Both patients were in American Society of Anesthetists class V and were in severe intractable hemorrhagic shock before the procedure. Computed tomography scan performed before discharge showed correct positioning of the stent graft and absence of endoleaks in all cases. At a mean follow-up of 29 months (range 1-79) all patients were alive but 1, who died of unrelated cause, and no intervention-related complication had occurred.ConclusionsImmediate stent-graft repair of posttraumatic aortic injury is a feasible and safe procedure. It allows us to minimize the surgical risks and to treat stable and unstable lesions even when associated lesions would contraindicate traditional surgical intervention
