Angioplasty of the terminal aorta: follow-up of 20 patients treated by PTA or PTA with stents

Endovascular treatment of steno-occlusions of the infrarenal abdominal aorta

“…rence or worsening of symptoms, excluding the potential for atherosclerosis progression proximally or distally to the target lesion [19,20] or inadequate stent expansion [18], we should recall intimal hyperplasia, which may cause restenosis and lead, when highly critical, even to thrombotic reocclusion of the stent [13,20,23,27]. However, in-stent neointimal hyperplasia is less frequent in the aorta than in other vascular districts, as this is a high-flow vessel [1]. Accordingly, in most cases, restenotic lesions can be treated with a percutaneous approach, with secondary patency rates approaching 100% [13,23,27].…”

“…Comunque, l'iperplasia intimale intra-stent a livello aortico è meno frequente che in altri distretti in relazione all'elevato flusso [1]. La maggior parte dei casi di restenosi può comunque essere trattata con approccio percutaneo con tassi di pervietà secondaria che raggiungono il 100% [13,23,27].…”

“…Infrarenal aortic occlusive disease is an uncommon consequence of atherosclerosis and mainly affects middleaged women with dyslipidaemia and a history of smoking [1]. Usual management involves endarterectomy for focal lesions or surgical bypass for more extensive aortoiliac disease and is characterised by established and favourable long-term results (90% 5-year and 75% 10-year patency rates) [2,3] even if burdened by a nonneg-…”

“…La malattia occlusiva dell'aorta sottorenale è una infrequente sequela dell'aterosclerosi e colpisce soprattutto soggetti di sesso femminile di età media, con dislipidemia e anamnesi di tabagismo [1]. Il trattamento convenzionale prevede l'endoarterectomia, per le lesioni focali, o il by-pass chirurgico per la patologia aorto-iliaca estesa, ed è caratterizzato da buoni risultati a lungo termine (pervietà del 90% a 5 anni e del 75% a 10 anni) [2,3], anche se è gravato da ligible rate of major complications (in 5-10% of cases).…”

In vitro haematic proteins adsorption and cytocompatibility study on acrylic copolymer to realise coatings for drug-eluting stents

“…A stent is an expandable tubular device [1,2] able to scaffold the vessel and to maintain the perviety of the artery after balloon angioplasty [3,4], in order to restore the normal flow conditions [5] in arteries clogged up by the build-up of fatty substances [6].…”
