The best in vitro conditions for two and three parallel stenting during endovascular aneurysm repair

This study is a continuation of our previous, innovative in vitro study, which analyzed the best endograft and one parallel-stent combination, but now analyzing the performance of two and three parallel stents. We have observed comparable results: 30% endograft oversizing is still probably the most optimal, and the Excluder-Viabahn combination is related to smaller gutters, but higher stent compression and risk of infolding, than with Endurant-BeGraft. Infolding was also greater with three than with two parallel stents. These novel in vitro results can be very useful in planning EVAR with several parallel-stent procedures, where there is a paucity of factual knowledge.
