Precannulated Fenestrated Endovascular Aneurysm Repair Using Guidewire Fixator: A Novel Method Using the Liungman Guidewire Fixator.

OBJECTIVE: By using a guidewire fixator, the distal guidewire position can be secured in an artery. This new principle enables a method for fenestrated endovascular aortic repair where the connection between the aortic branches and the stent graft fenestrations is made before inserting and deploying the stent graft.

METHODS: This is conducted using a fenestrated stent graft with preloaded catheters, through which the prepositioned and distally secured guidewires from the branches are inserted.

RESULTS: This report covers the method when implementing a single fenestration stent graft in pig.

CONCLUSIONS: Successful tests with single and dual fenestrated grafts have been conducted in pigs.
