Percutaneous transluminal angioplasty of abdominal aortic stenoses

Abstract

Percutaneous transluminal angioplasty (PTA) was performed on 25 patients with localized distal abdominal aortic stenoses. All patients were smokers and all complained of bilateral lower limb claudication. Eleven patients had small distal aortas and iliac vessels. Technically successful dilatation was achieved in all patients. Long-term follow-up was available on 17 of the patients. The mean follow-up period was 38 months. Cumulative patency at 5 years was 70%. Thirteen patients remain asymptomatic 15-83 months following PTA. Late failure occurred in 4 patients, 1-38 months following PTA. No complications related to PTA were experienced. PTA of localized aortic stenoses is a safe alternative to surgery and should be the treatment of choice in this condition.

Endovascular treatment of steno-occlusions of the infrarenal abdominal aorta

“…Endovascular treatment of infrarenal aortic stenosis has been proposed [28,29] as a viable alternative to surgical revascularisation since the 1980s, and data available have established the safety and effectiveness of PTA, with an 85% primary and a 90% secondary patency rate [7][8][9][10][11][12] together with a low (3%) risk of major complications, such as vessel-wall rupture and distal and visceral embolism [21]. However, most evidence concerns the treatment of focal (<20-mm) stenoses not involving the distal aortic bifurcation [21].…”

“…Il trattamento endovascolare delle stenosi dell'aorta sottorenale è stato proposto a partire dal 1980 [28,29] come una valida alternativa alla rivascolarizzazione chirurgica e i dati disponibili in letteratura hanno stabilito l'efficacia della PTA con pervietà primaria dell'85% e secondaria del 90% [7][8][9][10][11][12] e con basso tasso di complicanze maggiori (3%) quali la rottura della parete vasale e l'embolizzazione distale o viscerale [21]. Comunque la maggior parte dei dati riguarda il trattamento di stenosi focali (<20 mm) che non coinvolgevano la biforcazione aortica [21].…”

“…La mini-invasività, la riduzione della morbidità e dei costi rispetto alla chirurgia e i buoni risultati immediati e a distanza [7][8][9][10][11][12] hanno consolidato il ruolo della PTA come approccio di prima scelta nel trattamento delle stenosi focali dell'aorta sottorenale [11].…”

“…Its limited invasiveness, lower morbidity and costs in comparison to surgery and favourable early and long-term results [7][8][9][10][11][12] have subsequently established the role of PTA as the first-choice strategy in the management of focal infrarenal aortic stenosis [11].…”

Outcomes of endovascular treatment of chronic total occlusion of the infrarenal aorta

“…Recent studies have shown improved clinical outcomes of endovascular therapy in complex iliac lesions involving the aortic bifurcation due to recent advances in devices and skills. [9][10][11][12][13][14][15] However, there are a paucity of data on immediate and long-term outcomes of endovascular treatments of chronic aortic occlusive disease. 16,17 We therefore sought to investigate the immediate and longterm outcomes of endovascular therapy in patients with chronic total occlusion of the infrarenal aorta.…”
