Abstract

Purpose

The aim of this study was to evaluate the efficacy of endovascular treatment of isolated iliac artery aneurysms (IIAA) and compare our data with those reported in the literature.

Materials and methods

From May 2005 to December 2010, 32 patients (31 men and one woman; mean age 73±12 years) with a total of 40 IIAAs underwent endovascular treatment at our institute. We evaluated technical success, long-term patency, early and late complications and overall mortality.

Results

At a median follow-up of 36 months, we achieved a technical success of 100%, a primary patency of 95% and a secondary patency of 100%, with complete exclusion of the aneurysm in 84.6% of cases. In 12.8% of cases, there was a reduction in aneurysm sac volume, with an incidence of type II endoleak of 12.8%. Overall survival at 1, 2, 3, and 6 years was 96.8%, 84.2%, 66.6% and 64%, respectively.

Conclusions

Our study documents the effectiveness of endovascular treatment of iliac aneurysms, which has become the first-choice treatment at our institute. This finding is consistent with the most recent literature and confirms the safety and long-term patency of stent-graft placement.

Riassunto

Obiettivo

Scopo del presente lavoro è stato valutare l’efficacia del trattamento endovascolare degli aneurismi isolati dell’asse arterioso iliaco (IIAA) e confrontare i nostri dati con quelli della letteratura.

Materiali e metodi

Da maggio 2005 a dicembre 2010, 32 pazienti (31 maschi ed 1 femmina; età media 73±12 anni) con un totale di 40 IIAA sono stati sottoposti a trattamento endovascolare. Sono stati valutati il successo tecnico, la pervietà a distanza, le complicanze precoci e tardive e la mortalità complessiva.

Risultati

Ad un follow-up medio di 36 mesi, abbiamo ottenuto successo tecnico del 100%; pervietà primaria del 95% e pervietà secondaria del 100%; esclusione dal circolo dell’aneurisma dell’84,6%. Nel 12,8% dei casi si è osservata riduzione volumetrica della sacca aneurismatica con incidenza di endoleak di II tipo del 12,8%. La sopravvivenza complessiva ad 1, 2, 3, e 6 anni è stata del 96,8%, 84,2%, 66,6%, 64% rispettivamente.

Conclusioni

Il nostro studio documenta l’efficacia del trattamento endovascolare degli aneurismi iliaci, che è diventata l’opzione di prima scelta nel nostro istituto. Tale riscontro è in linea con i più recenti dati della letteratura e conferma la sicurezza e la validità a lungo termine del posizionamento di endoprotesi.
