ABSTRACT
AIMS:
The occurrence of type I endoleaks represent an ominous sign after endovascular aneurysms repair (EVAR). We report our experience using balloon-expandable stents (BES) for the treatment of proximal Type I endoleaks at five high-volume hospitals in Argentina. METHODS ANDRESULTS:
Of 1,395 patients who underwent EVAR, we retrospectively collected data of 29 (2%) consecutive patients who underwent additional BES to repair proximal type I endoleaks. The mean age was 75.8 years old (range 63-87) and 93% were male. A hostile anatomy was found in 89.6% of the cases. BES oversize (balloon/neck diameter ration ≥ 30%) was frequent (69%); whereas, BES/prosthesis diameter ratio was less than 1 in 79% of the cases. Complete and partial sealing was obtained 72 and 28% of the cases, respectively. There were no immediate or late surgical conversion or major complications related with stent implantation. At a median time follow-up of 14.9 months (25-75% interquartiles 4.5-17.5 months), there were no cardiovascular deaths, evidence of aneurysm sac enlargement or need for re-intervention.CONCLUSIONS:
Our preliminary results suggest that BES implantation for the treatment of proximal type I endoleaks is feasible and safe with favourable mid-term results and may preclude the need for surgical conversion.
