Current tips for ensuring successful transfemoral short limb cannulation in modular aortic endografts: a new method for incorporation in practice.

One of the most crucial steps in endovascular infrarenal abdominal aortic aneurysm repair is the short limb catheterization of the modular device and the confirmation of the intrastent position of the guidewire. Failed connection of the contralateral iliac limb to the main body because of malposition of the catheterizing guidewire may lead to serious complications. A new method confirming successful passage of the guidewire in the short leg of the main body of the modular stent graft, thus ensuring that the extension will be accurately docked within the short limb, is described in detail. Furthermore, current tips for ensuring successful short limb cannulation are also described in brief.
