Emergency endovascular repair of an acute aortocaval fistula with AAA: Case report and review of the literature
2009
A 72-year-old man with sudden abdominal pain and congestive cardiac failure presented a high-flow aortocaval fistula with a large abdominal aortic aneurysm as detected by Duplex ultrasonography and computed tomography angiography. As the patient’s multiple comorbidities precluded open repair, an emergency left aortouniiliac stent-graft deployment and femoro-femoral crossover bypass grafting were performed. Notwithstanding, incomplete exclusion of the fistula due to a small inflow from the contralateral iliac axis, the patient’s cardiac overload decreased with a rapid resolution of cardiac failure, allowing for a staged ligation of the right iliac artery with a complete occlusion of the aort…

THE POSTERIOR APPROACH IN THE REPAIR OF POPLITEAL ARTERY ANEURYSMS: A TWO CENTER EXPERIENCE
2010
Objective: Popliteal artery aneurysms (PAA) are most frequent among peripheral aneurysms. The most commonly performed surgical repair is proximal and distal ligation with a saphenous vein bypass. We aim to report the early and mid-term outcome of surgical repair of popliteal artery aneurysms via a posterior approach. Methods: A retrospective review of consecutive patients who underwent surgical PAA repair in two vascular surgery units between 1998 and 2009 was performed. Within this group, the posterior approach was used in 28 repairs in 26 patients (25 men). All patients had an ultrasound examination. Eighteen patients underwent conventional angiography while CT angiography with 3-D recons…
Quale tipo di allenamento fa bene al cuore?
2006
L’antica evidenza che i cuori dei così detti animali “atletici” (lepri, ratti selvaggi) abbiano una più alta densità capillare rispetto a quelli di specie più sedentarie con un simile peso corporeo (conigli, ratti di laboratorio) supporta l’ipotesi che sedute di allenamento ripetute nel tempo siano in grado di aumentare la vascolarizzazione del miocardio. Il rimodellamento vascolare capillare del cuore in risposta all’esercizio fisico è noto dipendere dalla sezione e dall’allocazione dei vasi lungo l’albero coronarico, dai fattori molecolarie meccanici, dall’età dei soggetti e dal tipo di programma di allenamento. Un lungo allenamento di endurance, in particolare, sembra essere il modello e…
Chimney and Periscope Grafts Observed Over 2 Years After Their Use to Revascularize 169 Renovisceral Branches in 77 Patients With Complex Aortic Aneu…
2013
Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; mean age 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch to visceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiring chimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned in advance and were not used as bailout. A standardized follow-up protocol including computed tomographic angiography, laboratory testing, and clinical examination…
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.
