Simple technique to ensure coaxial guidewire positioning for placement of iliac limb of modular aortic endograft.
Endovascular abdominal aortic aneurysm repair using a modular bifurcated stent-graft requires the initial placement of the main component in the infrarenal aorta, followed by insertion of additional iliac stent-graft(s) to exclude aneurysm and to securely affix the device. Placement of the contralateral iliac component within the main bifurcated device is critical in this endovascular procedure, as malpositioning of the contralateral iliac limb can require conversion to open aneurysm repair. A simple adjunctive technique utilizing a rotational maneuver of a pigtail catheter is described. This maneuver reliably confirms the proper placement of the contralateral iliac stent-graft within the main bifurcated device.
